(the “Parent”), through its wholly owned subsidiaries, is principally engaged in retail brokerage; securities trading; investment banking; investment advisory; retail, consumer, and commercial banking; and related financial services. We have offices throughout the United States and several European cities. Our major geographic area of concentration is throughout the United States, with a growing presence in the United Kingdom and Europe. Our company’s principal customers are individual investors, corporations, municipalities, and institutions. Basis of Presentation The consolidated financial statements include Stifel Financial Corp. and its wholly owned subsidiaries, principally Stifel, Nicolaus & Company, Incorporated (“Stifel”) and Stifel Bank & Trust (“Stifel Bank”). All material intercompany balances and transactions have been eliminated. Unless otherwise indicated, the terms “we,” “us,” “our,” or “our company” in this report refer to Stifel Financial Corp. and its wholly owned subsidiaries. The accompanying consolidated financial statements have been prepared in conformity with U.S. generally accepted accounting principles, which require management to make certain estimates and assumptions that affect the reported amounts. We consider significant estimates, which are most susceptible to change and impacted significantly by judgments, assumptions, and estimates, to be: valuation of financial instruments and investments in partnerships, accrual for contingencies, allowance for loan losses, derivative instruments and hedging activities, fair value of goodwill and intangible assets, provision for income taxes and related tax reserves, and forfeitures associated with stock-based compensation. Actual results could differ from those estimates. Certain amounts from prior periods have been reclassified to conform to the current period’s presentation. The effect of these reclassifications on our company’s previously reported consolidated financial statements was not material. Consolidation Policies The consolidated financial statements include the accounts of Stifel Financial Corp. and its subsidiaries. We also have investments or interests in other entities for which we must evaluate whether to consolidate by determining whether we have a controlling financial interest or are considered to be the primary beneficiary. In determining whether to consolidate these entities, we evaluate whether the entity is a voting interest entity or a variable interest entity (“VIE”). Voting Interest Entity. Voting interest entities are entities that have (i) total equity investment at risk sufficient to fund expected future operations independently, and (ii) equity holders who have the obligation to absorb losses or receive residual returns and the right to make decisions about the entity’s activities. We consolidate voting interest entities when we determine that there is a controlling financial interest, usually ownership of all, or a majority of, the voting interest. Variable Interest Entity. VIEs are entities that lack one or more of the characteristics of a voting interest entity. We are required to consolidate certain VIEs in which we have the power to direct the activities of the entity and the obligation to absorb significant losses or receive significant benefits. In other cases, we consolidate VIEs when we are deemed to be the primary beneficiary. The primary beneficiary is defined as the entity that has a variable interest, or a combination of variable interests, that maintains control and receives benefits or will absorb losses that are not pro rata with its ownership interests. The determination as to whether an entity is a VIE is based on the structure and nature of the entity. We also consider other characteristics, such as the ability to influence the decision-making relative to the entity’s activities and how the entity is financed. With the exception of entities eligible for the deferral codified in Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2010-10, “Consolidation: Amendments for Certain Investment Funds” (“ASU 2010-10”) (generally asset managers and investment companies), ASC 810 states that a controlling financial interest in an entity is present when an enterprise has a variable interest, or combination of variable interests, that have both the power to direct the activities of the entity that most significantly impact the entity’s economic performance and the obligation to absorb losses of the entity or the rights to receive benefits from the entity that could potentially be significant to the entity. Entities meeting the deferral provision defined by ASU 2010-10 are evaluated under the historical VIE guidance. Under the historical guidance, a controlling financial interest in an entity is present when an enterprise has a variable interest, or combination of variable interests, that will absorb a majority of the entity’s expected losses, receive a majority of the entity’s expected residual returns, or both. The enterprise with a controlling financial interest, known as the primary beneficiary, consolidates the VIE. We determine whether we are the primary beneficiary of a VIE by first performing a qualitative analysis of the VIE’s control structure, expected benefits and losses, and expected residual returns. This analysis includes a review of, among other factors, the VIE’s capital structure, contractual terms, which interests create or absorb benefits or losses, variability, related party relationships, and the design of the VIE. Where a qualitative analysis is not conclusive, we perform a quantitative analysis. We reassess our initial evaluation of an entity as a VIE and our initial determination of whether we are the primary beneficiary of a VIE upon the occurrence of certain reconsideration events. See Note 28 for additional information on VIEs.

Accounting Policies [Abstract]
Summary Of Significant Accounting Policies	NOTE 2 – Summary of Significant Accounting Policies Cash and Cash Equivalents We consider money market mutual funds and highly liquid investments with original maturities of three months or less that are not restricted or segregated to be cash equivalents. Cash and cash equivalents include money market mutual funds, deposits with banks, certificates of deposit, and federal funds sold. Cash and cash equivalents also include balances that Stifel Bank maintains at the Federal Reserve Bank. Cash Segregated for Regulatory Purposes Our broker-dealer subsidiaries are subject to Rule 15c3-3 under the Securities Exchange Act of 1934, which requires our company to maintain cash or qualified securities in a segregated reserve accounts for the exclusive benefit of its clients. In accordance with Rule 15c3-3, our company has portions of its cash segregated for the exclusive benefit of clients at December 31, 2015. Brokerage Client Receivables, Net Brokerage client receivables include receivables of our company’s broker-dealer subsidiaries, which represent amounts due on cash and margin transactions and are generally collateralized by securities owned by clients. Brokerage client receivables, primarily consisting of floating-rate loans collateralized by customer-owned securities, are charged interest at rates similar to other such loans made throughout the industry. The receivables are reported at their outstanding principal balance net of allowance for doubtful accounts. When a brokerage client receivable is considered to be impaired, the amount of the impairment is generally measured based on the fair value of the securities acting as collateral, which is measured based on current prices from independent sources, such as listed market prices or broker-dealer price quotations. Securities owned by customers, including those that collateralize margin or other similar transactions, are not reflected in the consolidated statements of financial condition. Securities Borrowed and Securities Loaned Securities borrowed require our company to deliver cash to the lender in exchange for securities and are included in receivables from brokers, dealers, and clearing organizations in the consolidated statements of financial condition. For securities loaned, we generally receive collateral in the form of cash in an amount in excess of the market value of securities loaned. Securities loaned are included in payables to brokers, dealers, and clearing organizations in the consolidated statements of financial condition. We monitor the market value of securities borrowed and loaned on a daily basis, with additional collateral obtained or refunded as necessary. Fees received or paid are recorded in interest revenue or interest expense. Substantially all of these transactions are executed under master netting agreements, which gives us right of offset in the event of counterparty default; however, such receivables and payables with the same counterparty are not set-off in the consolidated statements of financial condition. Securities Purchased Under Agreements to Resell and Repurchase Agreements Securities purchased under agreements to resell (“resale agreements”) are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. We obtain control of collateral with a market value equal to or in excess of the principal amount loaned and accrued interest under resale agreements. These agreements are short-term in nature and are collateralized by U.S. government agency securities. We value collateral on a daily basis, with additional collateral obtained when necessary to minimize the risk associated with this activity. Securities sold under agreements to repurchase (“repurchase agreements”) are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. We make delivery of securities sold under agreements to repurchase and monitor the value of collateral on a daily basis. When necessary, we will deliver additional collateral. Financial Instruments We measure certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents, financial instruments owned, available-for-sale securities, investments, financial instruments sold, but not yet purchased, and derivatives. Other than those separately discussed in the notes to the consolidated financial statements, the remaining financial instruments are generally short-term in nature, and their carrying values approximate fair value. The fair value of a financial instrument is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., “the exit price”) in an orderly transaction between market participants at the measurement date. We have categorized our financial instruments measured at fair value into a three-level classification in accordance with Topic 820, “Fair Value Measurement,” which established a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from independent sources. Unobservable inputs reflect our assumptions that market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the transparency of inputs as follows: Level 1 – Quoted prices (unadjusted) are available in active markets for identical assets or liabilities as of the measurement date. A quoted price for an identical asset or liability in an active market provides the most reliable fair value measurement, because it is directly observable to the market. Level 2 – Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the measurement date. The nature of these financial instruments includes instruments for which quoted prices are available but traded less frequently, derivative instruments whose fair value have been derived using a model where inputs to the model are directly observable in the market, or can be derived principally from or corroborated by observable market data, and instruments that are fair valued using other financial instruments, the parameters of which can be directly observed. Level 3 – Instruments that have little to no pricing observability as of the measurement date. These financial instruments do not have two-way markets and are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation. Valuation of Financial Instruments When available, we use observable market prices, observable market parameters, or broker or dealer prices (bid and ask prices) to derive the fair value of financial instruments. In the case of financial instruments transacted on recognized exchanges, the observable market prices represent quotations for completed transactions from the exchange on which the financial instrument is principally traded. A substantial percentage of the fair value of our financial instruments owned, available-for-sale securities, investments, and financial instruments sold, but not yet purchased, are based on observable market prices, observable market parameters, or derived from broker or dealer prices. The availability of observable market prices and pricing parameters can vary from product to product. Where available, observable market prices and pricing or market parameters in a product may be used to derive a price without requiring significant judgment. In certain markets, observable market prices or market parameters are not available for all products, and fair value is determined using techniques appropriate for each particular product. These techniques involve some degree of judgment. For investments in illiquid or privately held securities that do not have readily determinable fair values, the determination of fair value requires us to estimate the value of the securities using the best information available. Among the factors we consider in determining the fair value of investments are the cost of the investment, terms and liquidity, developments since the acquisition of the investment, the sales price of recently issued securities, the financial condition and operating results of the issuer, earnings trends and consistency of operating cash flows, the long-term business potential of the issuer, the quoted market price of securities with similar quality and yield that are publicly traded, and other factors generally pertinent to the valuation of investments. In instances where a security is subject to transfer restrictions, the value of the security is based primarily on the quoted price of a similar security without restriction but may be reduced by an amount estimated to reflect such restrictions. The fair value of these investments is subject to a high degree of volatility and may be susceptible to significant fluctuation in the near term, and the differences could be material. The degree of judgment used in measuring the fair value of financial instruments generally correlates to the level of pricing observability. Pricing observability is impacted by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established, and the characteristics specific to the transaction. Financial instruments with readily available active quoted prices for which fair value can be measured from actively quoted prices generally will have a higher degree of pricing observability and a lesser degree of judgment used in measuring fair value. Conversely, financial instruments rarely traded or not quoted will generally have less, or no, pricing observability and a higher degree of judgment used in measuring fair value. See Note 6 for additional information on how we value our financial instruments. Available-for-Sale and Held-to-Maturity Securities Securities available for sale include U.S. government agency securities; state and municipal securities; agency, non-agency, and commercial mortgage-backed securities; corporate fixed income securities; and asset-backed securities. Securities held to maturity are recorded at amortized cost based on our company’s positive intent and ability to hold these securities to maturity. Securities held to maturity include agency and commercial mortgage-backed securities, asset-backed securities, consisting of collateralized loan obligation securities and ARS, and corporate fixed income securities. We evaluate all securities in an unrealized loss position quarterly to assess whether the impairment is other-than-temporary on a quarterly basis. Our other-than-temporary impairment (“OTTI”) assessment is a subjective process requiring the use of judgments and assumptions. Accordingly, we consider a number of qualitative and quantitative criteria in our assessment, including the extent and duration of the impairment, recent events specific to the issuer and/or industry to which the issuer belongs, the payment structure of the security, external credit ratings and the failure of the issuer to make scheduled interest or principal payments, the value of underlying collateral, current market conditions, and our company’s ability and intent to hold the investment until its value recovers or the securities mature. We may determine that the decline in fair value of an investment is other-than-temporary if our analysis of these factors indicates that we will not recover our investment in the securities. If we determine that impairment on our debt securities is other-than-temporary and we have made the decision to sell the security or it is more likely than not that we will be required to sell the security prior to recovery of its amortized cost basis, we recognize the entire portion of the impairment in earnings. If we have not made a decision to sell the security and we do not expect that we will be required to sell the security prior to recovery of the amortized cost basis, we recognize only the credit component of OTTI in other income in the consolidated statements of operations. The remaining unrealized loss due to factors other than credit, or the non-credit component, is recorded in accumulated other comprehensive loss. We determine the credit component based on the difference between the security’s amortized cost basis and the present value of its expected future cash flows, discounted based on the purchase yield. The non-credit component represents the difference between the security’s fair value and the present value of expected future cash flows. We estimate the portion of loss attributable to credit using a discounted cash flow model. Key assumptions used in estimating the expected cash flows include default rates, loss severity, and prepayment rates. Assumptions used can vary widely based on the collateral underlying the securities and are influenced by factors such as collateral type, loan interest rate, geographical location of the borrower, and borrower characteristics. Unrealized gains and losses on our available-for-sale securities are reported, net of taxes, in accumulated other comprehensive income included in shareholders’ equity. Amortization of premiums and accretion of discounts are recorded as interest income using the interest method. Realized gains and losses from sales of securities available for sale are determined on a specific identification basis and are included in other revenue in the consolidated statements of operations in the period they are sold. Loan Classification We classify loans based on our investment strategy and management’s assessment of our intent and ability to hold loans for the foreseeable future or until maturity. Management’s intent and ability with respect to certain loans may change from time to time depending on a number of factors, including economic, liquidity, and capital conditions. The accounting and measurement framework for loans differs depending on the loan classification. The classification criteria and accounting and measurement framework for bank loans and loans held for sale are described below. Bank Loans and Allowance for Loan Losses Bank loans consist of commercial and residential mortgage loans, home equity loans, stock-secured loans, construction loans, and commercial and industrial and consumer loans originated or acquired by Stifel Bank. Bank loans include those loans that management has the intent and ability to hold and are recorded at outstanding principal adjusted for any charge-offs, allowance for loan losses, deferred origination fees and costs, and purchased discounts. Loan origination costs, net of fees, are deferred and recognized over the contractual life of the loan as an adjustment of yield using the interest method. Bank loans are generally collateralized by real estate, real property, marketable securities, or other assets of the borrower. Interest income is recognized using the effective interest rate method, which is based upon the respective interest rates and the average daily asset balance. Discount accretion is recognized using the effective interest rate method, which is based upon the respective interest rate and expected lives of loans. We regularly review the loan portfolio and have established an allowance for loan losses for inherent losses estimated to have occurred in the loan portfolio through a provision for loan losses charged to other operating expenses in the consolidated statements of operations. In providing for the allowance for loan losses, we consider historical loss experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available. Loans Held for Sale Loans that we intend to sell or for which we do not have the ability and intent to hold for the foreseeable future are classified as held for sale. Loans held for sale consist of fixed-rate and adjustable-rate residential real estate mortgage loans intended for sale. Loans held for sale are stated at lower of cost or market value. Declines in market value below cost and any gains or losses on the sale of these assets are recognized in other revenues in the consolidated statements of operations. Market value is determined based on prevailing market prices for loans with similar characteristics or on sale contract prices. Deferred fees and costs related to these loans are not amortized but are recognized as part of the cost basis of the loan at the time it is sold. Because loans held for sale are reported at lower of cost or market value, an allowance for loan losses is not established for loans held for sale. Impaired Loans A loan is considered impaired when, based on current information and events, it is probable that the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement will not be collectible. Factors considered in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. We determine the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Once a loan is determined to be impaired, when principal or interest becomes 90 days past due or when collection becomes uncertain, the accrual of interest and amortization of deferred loan origination fees is discontinued (“non-accrual status”) and any accrued and unpaid interest income is reversed. Loans placed on non-accrual status are returned to accrual status when all delinquent principal and interest payments are collected and the collectibility of future principal and interest payments is reasonably assured. Loan losses are charged against the allowance when we believe the uncollectibility of a loan balance is certain. Subsequent recoveries, if any, are credited to the allowance for loan losses. Large groups of smaller balance homogenous loans are collectively evaluated for impairment. Accordingly, we do not separately identify individual consumer and residential loans for impairment measurements. Impairment is measured on a loan-by-loan basis for non-homogeneous loans, and a specific allowance is established for individual loans determined to be impaired. Impairment is measured by comparing the carrying value of the impaired loan to the present value of its expected cash flow discounted at the loan’s effective interest rate, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent. Investments Our broker-dealer subsidiaries report changes in fair value of marketable and non-marketable securities in other income in the consolidated statements of operations. The fair value of marketable investments is generally based on either quoted market or dealer prices. The fair value of non-marketable securities is based on management’s estimate using the best information available, which generally consists of quoted market prices for similar securities and internally developed discounted cash flow models. Investments in the consolidated statements of financial condition contain investments in securities that are marketable and securities that are not readily marketable. These investments are not included in our broker-dealer trading inventory or available-for-sale or held-to-maturity portfolios and represent the acquiring and disposing of debt or equity instruments for our benefit. Fixed Assets Office equipment is depreciated on an accelerated basis over the estimated useful life of the asset of two to seven years. Leasehold improvements are amortized on a straight-line basis over the lesser of the estimated useful life of the asset or the term of the lease. Buildings and building improvements are amortized on a straight-line basis over the estimated useful life of the asset of three to thirty-nine years. Depreciation expense is recorded in occupancy and equipment rental expense in the consolidated statements of operations. Office equipment, leasehold improvements, and property are stated at cost net of accumulated depreciation and amortization in the consolidated statements of financial condition. Office equipment is reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable. Goodwill and Intangible Assets Goodwill represents the cost of acquired businesses in excess of the fair value of the related net assets acquired. We test goodwill for impairment on an annual basis and on an interim basis when certain events or circumstances exist. We test for impairment at the reporting unit level, which is generally at the level of or one level below our company’s business segments. For both the annual and interim tests, we have the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, we determine it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, then performing the two-step impairment test is not required. However, if we conclude otherwise, we are then required to perform the first step of the two-step impairment test. Goodwill impairment is determined by comparing the estimated fair value of a reporting unit with its respective carrying value. If the estimated fair value exceeds the carrying value, goodwill at the reporting unit level is not deemed to be impaired. If the estimated fair value is below carrying value, however, further analysis is required to determine the amount of the impairment. Additionally, if the carrying value of a reporting unit is zero or a negative value and it is determined that it is more likely than not the goodwill is impaired, further analysis is required. The estimated fair values of the reporting units are derived based on valuation techniques we believe market participants would use for each of the reporting units. We have elected July 31 as our annual impairment testing date. Identifiable intangible assets, which are amortized over their estimated useful lives, are tested for potential impairment whenever events or changes in circumstances suggest that the carrying value of an asset or asset group may not be fully recoverable. Loans and Advances We offer transition pay, principally in the form of upfront loans, to financial advisors and certain key revenue producers as part of our company’s overall growth strategy. These loans are generally forgiven by a charge to compensation and benefits over a five- to ten-year period if the individual satisfies certain conditions, usually based on continued employment and certain performance standards. We monitor and compare individual financial advisor production to each loan issued to ensure future recoverability. If the individual leaves before the term of the loan expires or fails to meet certain performance standards, the individual is required to repay the balance. In determining the allowance for doubtful receivables from former employees, management considers the facts and circumstances surrounding each receivable, including the amount of the unforgiven balance, the reasons for the terminated employment relationship, and the former employees’ overall financial situation. Derivative Instruments and Hedging Activities We recognize all of our derivative instruments at fair value as either assets or liabilities in the consolidated statements of financial condition. These instruments are recorded in other assets or accounts payable and accrued expenses in the consolidated statements of financial condition and in the operating section of the consolidated statements of cash flows as increases or decreases of other assets and accounts payable and accrued expenses. Our company’s policy is not to offset fair value amounts recognized for derivative instruments and fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral arising from derivative instruments recognized at fair value executed with the same counterparty under master netting arrangements. The accounting for changes in the fair value (i.e., gains and losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments under Topic 815, “Derivatives and Hedging,” we must also designate the hedging instrument or transaction, based upon the exposure being hedged. For derivative instruments that are designated and qualify as cash flow hedges (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive income, net of tax, and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item, if any, is recognized in current earnings during the period of change. We do not use derivatives for trading or speculative purposes and, at December 31, 2015, do not have any derivatives that are not designated in qualifying cash flow hedging relationships. See Note 15 for additional details. Revenue Recognition Customer securities transactions are recorded on a settlement date basis, with related commission revenues and expenses recorded on a trade date basis. Commission revenues are recorded as the amount charged to the customer, which, in certain cases, may include varying discounts. Principal securities transactions are recorded on a trade date basis. We typically distribute our proprietary equity research products to our client base of institutional investors at no charge. These proprietary equity research products are accounted for as a cost of doing business. Investment banking revenues, which include underwriting fees, management fees, advisory fees, and sales credits earned in connection with the distribution of the underwritten securities, are recorded when services for the transactions are completed under the terms of each engagement. Expenses associated with such transactions are deferred until the related revenue is recognized or the engagement is otherwise concluded. Investment banking revenues are presented net of related unreimbursed expenses. Expenses related to investment banking deals not completed are recognized as non-interest expenses in the consolidated statements of operations. For the periods presented, there were no significant expenses recognized for incomplete transactions. We have not recognized any incentive income that is subject to contingent repayments. Asset management and service fees are recorded when earned, based on the period-end assets in the accounts, and consist of customer account service fees, per account fees (such as IRA fees), and wrap fees on managed accounts. We earn fees from the investment partnerships that we manage or of which we are a general partner. Such management fees are generally based on the net assets or committed capital of the underlying partnerships. We have agreed, in certain cases, to waive management fees, in lieu of making a cash contribution, in satisfaction of our general partner investment commitments to the investment partnerships. In these cases, we generally recognize our management fee revenues at the time when we are allocated a special profit interest in realized gains from these partnerships. Operating Leases We lease office space and equipment under operating leases. We recognize rent expense related to these operating leases on a straight-line basis over the lease term. The lease term commences on the earlier of the date when we become legally obligated for the rent payments or the date on which we take possession of the property. For tenant improvement allowances and rent holidays, we record a deferred rent liability in accounts payable and accrued expenses in the consolidated statements of financial condition and amortize the deferred rent over the lease term as a reduction to occupancy and equipment rental expense in the consolidated statements of operations. Income Taxes We compute income taxes using the asset and liability method, under which deferred income taxes are provided for the temporary differences between the financial statement carrying amounts and the tax basis of our company’s assets and liabilities. We establish a valuation allowance for deferred tax assets if it is more likely than not that these items will either expire before we are able to realize their benefits, or that future deductibility is uncertain. We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. We recognize interest and penalties related to uncertain tax positions in provision for income taxes/(benefit) in the consolidated statements of operations. See Note 24 for further information regarding income taxes. Foreign Currency Translation We consolidate our foreign subsidiaries, which have designated their local currency as their functional currency. Assets and liabilities of these foreign subsidiaries are translated at year-end rates of exchange. Revenues and expenses are translated at an average rate for the period. In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 830, “Foreign Currency Matters,” gains or losses resulting from translating foreign currency financial statements are reflected in accumulated other comprehensive income, a separate component of shareholders’ equity. Gains or losses resulting from foreign currency transactions are included in net income. Recently Adopted Accounting Guidance Business Combinations In September 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2015-16, Business Combinations (Topic 805): "Simplifying the Accounting for Measurement-Period Adjustments" (“ASU 2015-16”), which eliminates the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. Under this ASU, acquirers must recognize measurement-period adjustments in the period in which they determine the amounts, including the effect on earnings of any amounts they would have recorded in previous periods if the accounting had been completed at the acquisition date. This guidance is effective for fiscal years beginning after December 15, 2016, with early adoption permitted. We elected to early adopt this ASU in the third quarter of 2015. The adoption of ASU 2015-16 did not have a material impact on our consolidated financial statements. Disclosures for Investments in Certain Entities That Calculate Net Asset Value Per Share In May 2015, the FASB issued ASU No. 2015-07, “Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities That Calculate Net Asset Value Per Share (or Its Equivalent).” The guidance removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The guidance also removes the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. Rather, those disclosures are limited to investments for which the entity has elected to measure the fair value using that practical expedient. The guidance is effective for fiscal years beginning after December 15, 2015, and for interim periods within those years. The guidance shall be applied retrospectively for all periods presented. Early application is permitted. The guidance is not expected to have a material impact on our consolidated financial statements. Interest - Imputation of Interest In April 2015, the FASB issued ASU No. 2015-03, “Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs” (“ASU 2015-03”). The guidance in ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. ASU 2015-03 is effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted, and a retrospective approach is required. The guidance is not expected to have a material impact on our consolidated financial statements. Consolidation In February 2015, the FASB issued ASU No. 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis” that amends the criteria for determining whether limited partnerships and similar entities are VIEs, clarifies when a general partner or asset manager should consolidate an entity, and eliminates the indefinite deferral of certain aspects of VIE accounting guidance for investments in certain investment funds. Money market funds registered under Rule 2a-7 of the Investment Company Act and similar funds are exempt from consolidation under the new guidance. The new accounting guidance is effective beginning on January 1, 2016. Early adoption is permitted. We elected to early adopt this ASU in 2015. The adoption of ASU 2015-02 did not have a material impact on our consolidated financial statements. Repurchase Agreements In June 2014, the FASB issued ASU No. 2014-11, "Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures," ("ASU 2014-11") amending FASB Accounting Standards Codification Topic 860, "Transfers and Servicing." The amended guidance changes the accounting for repurchase-to-maturity transactions and repurchase financing arrangements. The guidance also requires new disclosures for certain transfers accounted for as sales and collateral supporting transactions that are accounted for as secured borrowings. ASU 2014-11 is effective for annual and interim periods beginning after December 15, 2014, except for the disclosures related to secured borrowings, which are effective for annual periods beginning after December 15, 2014, and for interim periods beginning after March 15, 2015. The adoption of ASU 2014-11 did not have a material impact on our results of operations or financial position. Revenue Recognition In May 2014, the FASB issued ASU No. 2014-09, "Revenue From Contracts with Customers (Topic 606)," ("ASU 2014-09") which supersedes current revenue recognition guidance, including most industry-specific guidance. ASU 2014-09 requires a company to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods and services. The guidance also requires additional disclosures regarding the nature, amount, timing, and uncertainty of revenue that is recognized. The FASB has approved a one-year deferral of this standard, and this pronouncement is now effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and is to be applied using one of two retrospective application methods, with early application not permitted. We are currently evaluating the impact the new guidance will have on our consolidated financial statements. Discontinued Operations In April 2014, the FASB issued ASU No. 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity,” (“ASU 2014-08”) amending FASB ASC Topic 205-20, “Discontinued Operations,” (“ASC 205-20”). The amended guidance changes the criteria for reporting discontinued operations and requires new disclosures. ASU 2014-08 is effective for annual and interim periods beginning on or after December 15, 2014, and will be applied prospectively. The adoption of ASU 2014-08 did not have a material impact on our consolidated financial statements.

Business Combinations [Abstract]
Acquisitions	NOTE 3 – Acquisitions Kelwynne, LLC On October 7, 2015, Stifel Aviation Finance Acquisition, LLC (“SAFA”) completed the acquisition of Kelwynne, LLC. On October 19, 2015, SAFA sold Kelwynne, LLC to Stifel Aviation Finance II, LLC (“SAF2”). Stifel Venture Corp owns 40% of SAF2’s Class A units. Upon SAFA’s sale of Kelwynne, LLC to SAF2, the Company deconsolidated SAF2, as it was no longer majority-owned or controlled the Company. Barclays’ Wealth and Investment Management, Americas On December 4, 2015, we completed the purchase of the Barclays' Wealth and Investment Management, Americas (“Barclays”), franchise in the U.S. The Company paid purchase consideration that was funded with cash from operations. As part of that transaction, Stifel Bank, a wholly owned subsidiary of the Company, acquired approximately $600.0 million of bank loans, at fair value, from Barclays. The fair values for those loans were estimated using discounted cash flow analyses using interest rates currently being offered for loans with similar terms. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805 (“Topic 805”), “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $32.2 million of goodwill in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management segment. The allocation of the purchase price is preliminary and will be finalized upon completion of the analysis of the fair values of the net assets of Barclays at closing and the identified intangible assets. The final goodwill and intangible assets recorded on the consolidated statement of financial condition may differ from that reflected herein as a result of future measurement period adjustments. In management’s opinion, the goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of the hired financial advisors and the conversion of the customer accounts to the Stifel platform. Goodwill is expected to be deductible for federal income tax purposes. In addition, deferred consideration is payable based on certain revenue generated by Stifel in accordance with the distribution agreement. The deferred consideration of $15.6 million has been recognized as a liability and is included in accounts payable and accrued expenses in the consolidated statements of financial condition at December 31, 2015. In the first quarter of 2016, the Company finalized the service terms for the approximately 2.0 million restricted stock units granted in connection with the Barclays transaction. The Company expects to expense approximately $60.0 million in the first quarter of 2016, related to the majority of those awards. Pro forma information is not presented, because the acquisition is not considered to be material, as defined by the Securities and Exchange Commission (the “SEC”). The results of operations of Barclays have been included in our results prospectively from the date of acquisition. Sterne Agee Group, Inc. On June 5, 2015, we completed the purchase of all of the outstanding shares of common stock of Sterne Agee Group, Inc. (“Sterne Agee”), a financial services firm that offers comprehensive wealth management and investment services to a diverse client base including corporations, municipalities, and individual investors. The purchase was completed pursuant to the merger agreement dated February 23, 2015. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805 (“Topic 805”), “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $90.1 million of goodwill and intangible assets in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management and Institutional Group segments. The allocation of the purchase price is preliminary and will be finalized upon completion of the analysis of the fair values of the net assets of Sterne Agee at closing and the identified intangible assets. The final goodwill and intangible assets recorded on the consolidated statement of financial condition may differ from that reflected herein as a result of future measurement period adjustments. In management’s opinion, the goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of Sterne Agee’s business and the reputation and expertise of Sterne Agee in the financial services sector. On June 5, 2015, certain employees were granted restricted stock units of our company as retention. The fair value of the awards issued as retention was $23.8 million. The fair value of the awards is based upon the closing price of our company’s common stock on the date of grant. There are no continuing service requirements associated with these restricted stock units, and accordingly, they were expensed at date of grant. This charge is included in compensation and benefits in the consolidated statement of operations for nine months ended September 30, 2015. In addition, we have paid $33.8 million in the form of notes to associates for retention. These notes will be forgiven by a charge to compensation and benefits over a five- to ten-year period if the individual satisfies certain conditions, usually based on continued employment and certain performance standards. Prior to the closing date, Sterne Agee had established adequate reserves for various claims that were included in the opening balance sheet. During the third quarter of 2015, this matter was settled and paid, and the excess reserves associated with the Canyon Ridge matter were distributed to Sterne Agee Group, Inc. shareholders. Under the terms of the agreements governing the acquisition, we have withheld a portion of the purchase price of Sterne Agee Group, Inc. pending the resolution of currently existing or subsequently arising liabilities relating to the operation of the Sterne Agee Group Inc. business prior to the closing of the acquisition. Based upon currently available information and review with counsel, we believe the amounts which we are allowed to withhold will be adequate to fully indemnify us from any losses related to the pre-closing operations of Sterne Agee Group, Inc. Pro forma information is not presented, because the acquisition is not considered to be material, as defined by the SEC. The results of operations of Sterne Agee have been included in our results prospectively from the date of acquisition. Merchant Capital, LLC On December 31, 2014, we acquired Merchant, a public finance investment banking firm headquartered in Montgomery, Alabama, which serves the Southeastern market. The strategic combination of our company and Merchant is expected to further strengthen our company’s position in several key underwriting markets in the Southeast. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805 (“Topic 805”), “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $17.9 million of goodwill as an asset in the consolidated statement of financial condition, which has been allocated to our company's Institutional Group segment. In management’s opinion, the goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of Merchant’s business and the reputation and expertise of Merchant in the public finance space within the investment banking sector. 1919 Investment Counsel & Trust Co., National Association On November 7, 2014, we completed the acquisition of 1919 Investment Counsel and 1919, an asset management firm and trust company that provides customized investment advisory and trust services, on a discretionary basis, to individuals, families, and institutions throughout the country. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805 (“Topic 805”), “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $11.6 million of goodwill as an asset in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management segment. Identifiable intangible assets purchased by our company consisted of customer relationships with estimated acquisition-date fair value of $6.1 million. In management’s opinion, the goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of 1919 Investment Counsel’s business and the reputation and expertise of 1919 Investment Counsel in the asset management sector and as a trust company. On November 7, 2014, certain employees were granted restricted stock or restricted stock units of our company as retention. The fair value of the awards issued as retention was $11.2 million. There are no continuing service requirements associated with these restricted stock units, and accordingly, they were expensed at date of grant. This charge is included in compensation and benefits in the consolidated statement of operations for the year ended December 31, 2014. In addition, we have paid $10.8 million in the form of notes to associates for retention. These notes will be forgiven by a charge to compensation and benefits over a five- to ten-year period if the individual satisfies certain conditions, usually based on continued employment and certain performance standards. Oriel Securities On July 31, 2014, we completed the acquisition of Oriel, a London-based stockbroking and investment banking firm. The combination of our company and Oriel has created a significant middle-market investment banking group in London, with broad research coverage across most sectors of the economy, equity and debt sales and trading, and investment banking services. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805 (“Topic 805”), “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $18.2 million of goodwill as an asset in the consolidated statement of financial condition, which has been allocated to our company’s Institutional Group segment. Identifiable intangible assets purchased by our company consisted of trade name and non-compete agreements with estimated acquisition-date fair values of $1.9 million and $1.4 million, respectively. In management’s opinion, the goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of Oriel’s business and the reputation and expertise of Oriel in the investment banking sector in the United Kingdom. On July 31, 2014, certain employees were granted restricted stock or restricted stock units of our company as retention. The fair value of the awards issued as retention was $6.8 million. There are no continuing service requirements associated with these restricted stock units, and accordingly, they were expensed at date of grant. This charge is included in compensation and benefits in the consolidated statement of operations for the year ended December 31, 2014. De La Rosa & Co. On April 3, 2014, we acquired De La Rosa, a California-based public finance investment banking boutique. The addition of the De La Rosa team is expected to further strengthen our company’s position in a number of key underwriting markets in California. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805 (“Topic 805”), “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $17.4 million of goodwill as an asset in the consolidated statement of financial condition, which has been allocated to our company’s Institutional Group segment. Identifiable intangible assets purchased by our company consisted of customer relationships and trade name with estimated acquisition-date fair values of $0.2 million and $1.8 million, respectively. In management’s opinion, the goodwill represents the value expected from the synergies created through the operational enhancement benefits that will result from the integration of De La Rosa’s business and the reputation and expertise of De La Rosa in the investment banking sector. Acacia Federal Savings Bank (“Acacia Federal”) On October 31, 2013, Stifel Bank completed its acquisition of Acacia Federal Savings Bank, a federally chartered savings institution with one retail branch. Under the agreement, we acquired approximately $337.1 million of loans and $180.4 million of other assets (primarily cash and due from banks and investment securities). In addition, we assumed approximately $435.4 million of deposits and $10.0 million of other liabilities. Assets acquired and liabilities assumed were recorded at fair value in accordance with ASC 805, “Business Combinations.” The fair values for loans were estimated using discounted cash flow analyses using interest rates currently being offered for loans with similar terms. This value was reduced by an estimate of probable losses and the credit risk associated with the loans. The fair values of deposits were estimated by discounting cash flows using interest rates currently being offered on deposits with similar maturities. We recognized a $7.6 million bargain purchase gain during the year ended December 31, 2013, which is included in other income in the consolidated statements of operations. Ziegler Capital Management, LLC On November 30, 2013, we acquired ZCM, an asset management firm that provides investment solutions for institutions, mutual fund sub-advisory clients, municipalities, pension plans, Taft-Hartley plans, and individual investors. The acquisition was accounted for under the acquisition method of accounting in accordance with ASC 805 (“Topic 805”), “Business Combinations.” Accordingly, goodwill was measured as the excess of the acquisition-date fair value of the consideration transferred over the amount of acquisition-date identifiable assets acquired net of assumed liabilities. We recorded $6.8 million of goodwill as an asset in the consolidated statement of financial condition, which has been allocated to our company’s Global Wealth Management segment. Identifiable intangible assets purchased by our company consisted of customer relationships and trade name with acquisition-date fair values of $3.4 million and $0.1 million, respectively.

KBW, Inc. On February 15, 2013, we completed the purchase of all of the outstanding shares of common stock of KBW, Inc. (“KBW, Inc.”), a full-service investment bank specializing in the financial services industry based in New York, New York. The purchase was completed pursuant to the merger agreement dated November 5, 2012.

In addition, on February 15, 2013, certain employees were granted restricted stock or restricted stock units of our company as retention. The fair value of the awards issued as retention was $30.6 million.

Fair Value Measurements

NOTE 6 – Fair Value Measurements

Cash Equivalents

Financial Instruments Owned and Available-For-Sale Securities

Investments

Corporate equity securities, mutual funds, and U.S. government securities are valued based on quoted prices in active markets and reported in Level 1.

ARS for which the market has been dislocated and largely ceased to function are reported as Level 3 assets. The methods used to value ARS are discussed above.

Investments in partnerships and other investments include our general and limited partnership interests in investment partnerships and direct investments in non-public companies. The net assets of investment partnerships consist primarily of investments in non-marketable securities. The value of these investments is at risk to changes in equity markets, general economic conditions, and a variety of other factors. We estimate fair value for private equity investments based on our percentage ownership in the net asset value of the entire fund, as reported by the fund or on behalf of the fund, after indication that the fund adheres to applicable fair value measurement guidance.

Other-Than-Temporary Impairment

We believe the gross unrealized losses related to all other securities of $21.0 million as of December 31, 2015, are attributable to issuer-specific credit spreads and changes in market interest rates and asset spreads. We, therefore, do not expect to incur any credit losses related to these securities. In addition, we have no intent to sell these securities with unrealized losses, and it is not more likely than not that we will be required to sell these securities prior to recovery of the amortized cost. No OTTI charge was recorded during the year ended December 31, 2015 related to these securities. Accordingly, we have concluded that the impairment on these securities is not other-than-temporary.

Legal Proceedings	12 Months Ended
Legal Proceedings	Dec. 31, 2015
Loss Contingency Information About Litigation Matters [Abstract]
Legal Proceedings	NOTE 19 – Legal Proceedings Our company and its subsidiaries are named in and subject to various proceedings and claims arising primarily from our securities business activities, including lawsuits, arbitration claims, class actions, and regulatory matters. Some of these claims seek substantial compensatory, punitive, or indeterminate damages. Our company and its subsidiaries are also involved in other reviews, investigations, and proceedings by governmental and self-regulatory organizations regarding our business, which may result in adverse judgments, settlements, fines, penalties, injunctions, and other relief. We are contesting the allegations in these claims, and we believe that there are meritorious defenses in each of these lawsuits, arbitrations, and regulatory investigations. In view of the number and diversity of claims against our company, the number of jurisdictions in which litigation is pending, and the inherent difficulty of predicting the outcome of litigation and other claims, we cannot state with certainty what the eventual outcome of pending litigation or other claims will be. We have established reserves for potential losses that are probable and reasonably estimable that may result from pending and potential legal actions, investigations, and regulatory proceedings. In many cases, however, it is inherently difficult to determine whether any loss is probable or even possible or to estimate the amount or range of any potential loss, particularly where proceedings may be in relatively early stages or where plaintiffs are seeking substantial or indeterminate damages. Matters frequently need to be more developed before a loss or range of loss can reasonably be estimated. In our opinion, based on currently available information, review with outside legal counsel, and consideration of amounts provided for in our consolidated financial statements with respect to these matters, including the matters described below, the ultimate resolution of these matters will not have a material adverse impact on our financial position and results of operations. However, resolution of one or more of these matters may have a material effect on the results of operations in any future period, depending upon the ultimate resolution of those matters and depending upon the level of income for such period. For matters where a reserve has not been established and for which we believe a loss is reasonably possible, as well as for matters where a reserve has been recorded but for which an exposure to loss in excess of the amount accrued is reasonably possible, based on currently available information, we believe that such losses will not have a material effect on our consolidated financial statements. SEC/Wisconsin Lawsuit A civil lawsuit was filed against our company by the SEC in connection with our role in the sale of collateralized debt obligations (“CDOs”) investments to five Southeastern Wisconsin school districts (the “school districts”) in U.S. District Court for the Eastern District of Wisconsin on August 10, 2011. The SEC has asserted claims under Section 15c(1) (A), Section 10b and Rule 10b-5 of the Exchange Act and Sections 17a(1), 17a(2), and 17a(3) of the Securities Act. The claims are based upon both alleged misrepresentations and omissions in connection with the sale of the CDOs to the school districts, as well as the allegedly unsuitable nature of the CDOs. We answered, denied the substantive allegations of the amended complaint, and asserted various affirmative defenses. In January 2016, the parties filed motions for summary judgment and are awaiting the court’s rulings on those motions. The lawsuit had been set for trial commencing on April 11, 2016, but the Court has postponed the trial to commence on September 12, 2016. While there can be no assurance that we will be successful, we intend to vigorously defend the claims. EDC Bond Issuance Matter We have been named, along with other parties, in a lawsuit filed in Wisconsin state court asserting various claims by LDF Acquisition LLC (“LDF”), a special purpose vehicle created by Saybrook Tax Exempt Investors LLC (collectively “Saybrook”) and by the Lac Du Flambeau Band of Lake Superior Chippewa Indians and its Lake of the Torches Economic Development Corporation (the “Tribe”) in which, among other things, Saybrook seeks repayment from the Tribe for the proceeds from a $50 million 2008 bond offering (“the bonds’) and in which the Tribe seeks to avoid repayment, as well as other claims against us and others. We were the initial purchaser of the bonds, which were immediately sold to LDF. The claims asserted against Stifel are for breaches of implied warranties of validity and title, securities fraud, and statutory misrepresentation under Wisconsin state law, intentional and negligent misrepresentations relating to those matters. Saybrook seeks rescissionary relief as well as restitutionary damages, including the amounts paid for the bonds, plus costs. The claims are set for trial commencing on October 11, 2016. While there can be no assurance that we will be successful, we intend to vigorously defend the claims. Broyles, et al. v. Cantor Fitzgerald & Co. et al. Matter Our Company, Stifel, and Stone & Youngberg, LLC (“Stone & Youngberg”) are named in an Amended Complaint filed in U.S. District Court for the Middle District of Louisiana alleging fraud on the part of Stone & Youngberg in the formation of the Collybus CDO manufactured by Cantor Fitzgerald & Co. (“Cantor”) and purchased by Commonwealth Advisors (“CA”) on behalf of several CA funds, as well as in connection with other transactions in the CA funds with CA. The original Complaint named Cantor, CA, and CA’s CEO, Walter Morales. The CA funds filed a Chapter 11 bankruptcy petition, which stayed the original lawsuit until the reorganization plan was entered by the court in the fall of 2013. Shortly thereafter, the CA funds filed their first Amended Complaint, which has been amended several times since then. The claims are set for trial commencing on November 28, 2016. While there can be no assurance that we will be successful, we intend to vigorously defend the claims. We have established reserves supported by purchase price consideration the Company has withheld pursuant to the terms of the acquisition of Stone & Youngberg in 2011, which at this time, we believe are adequate.

Off-Balance Sheet Credit Risk	12 Months Ended
Off-Balance Sheet Credit Risk	Dec. 31, 2015
Concentration Risks Types No Concentration Percentage [Abstract]
Off-Balance Sheet Credit Risk	NOTE 23 – Off-Balance Sheet Credit Risk In the normal course of business, we execute, settle, and finance customer and proprietary securities transactions. These activities expose our company to off-balance sheet risk in the event that customers or other parties fail to satisfy their obligations. In accordance with industry practice, securities transactions generally settle within three business days after trade date. Should a customer or broker fail to deliver cash or securities as agreed, we may be required to purchase or sell securities at unfavorable market prices. We borrow and lend securities to facilitate the settlement process and finance transactions, utilizing customer margin securities held as collateral. We monitor the adequacy of collateral levels on a daily basis. We periodically borrow from banks on a collateralized basis, utilizing firm and customer margin securities in compliance with SEC rules. Should the counterparty fail to return customer securities pledged, we are subject to the risk of acquiring the securities at prevailing market prices in order to satisfy our customer obligations. We control our exposure to credit risk by continually monitoring our counterparties’ positions, and where deemed necessary, we may require a deposit of additional collateral and/or a reduction or diversification of positions. Our company sells securities it does not currently own (short sales) and is obligated to subsequently purchase such securities at prevailing market prices. We are exposed to risk of loss if securities prices increase prior to closing the transactions. We control our exposure to price risk from short sales through daily review and setting position and trading limits. We manage our risks associated with the aforementioned transactions through position and credit limits and the continuous monitoring of collateral. Additional collateral is required from customers and other counterparties when appropriate. We have accepted collateral in connection with resale agreements, securities borrowed transactions, and customer margin loans. Under many agreements, we are permitted to sell or repledge these securities held as collateral and use these securities to enter into securities lending arrangements or to deliver to counterparties to cover short positions. At December 31, 2015 and 2014, the fair value of securities accepted as collateral where we are permitted to sell or repledge the securities was $2.4 billion and $1.2 billion, respectively, and the fair value of the collateral that had been sold or repledged was $278.7 million and $39.2 million, respectively. We enter into interest rate derivative contracts to manage exposures that arise from business activities that result in the receipt or payment of future known and uncertain cash amounts, the value of which are determined by interest rates. Our derivative financial instruments are principally used to manage differences in the amount, timing, and duration of our known or expected cash payments related to certain variable-rate affiliated deposits. Interest rate swaps designated as cash flow hedges involve the receipt of variable-rate amounts from a counterparty in exchange for us making fixed-rate payments. Our interest rate hedging strategies may not work in all market environments and, as a result, may not be effective in mitigating interest rate risk. Derivatives’ notional contract amounts are not reflected as assets or liabilities in the consolidated statements of financial condition. Rather, the market or fair value of the derivative transactions are reported in the consolidated statements of financial condition as other assets or accounts payable and accrued expenses, as applicable. For a complete discussion of our activities related to derivative instruments, see Note 15 in the notes to consolidated financial statements. In the ordinary course of business, Stifel Bank has commitments to originate loans, standby letters of credit, and lines of credit. Commitments to originate loans are agreements to lend to a customer as long as there is no violation of any condition established by the contract. These commitments generally have fixed expiration dates or other termination clauses and may require payment of a fee. Since a portion of the commitments may expire without being drawn upon, the total commitment amounts do not necessarily represent future cash commitments. Each customer’s creditworthiness is evaluated on a case-by-case basis. The amount of collateral obtained, if necessary, is based on the credit evaluation of the counterparty. Collateral held varies, but may include accounts receivable, inventory, property, plant and equipment, commercial real estate, and residential real estate. At December 31, 2015 and 2014, Stifel Bank had outstanding commitments to originate loans aggregating $130.5 million and $122.8 million, respectively. The commitments extended over varying periods of time, with all commitments at December 31, 2015, scheduled to be disbursed in the following three months. Through Stifel Bank, in the normal course of business, we originate residential mortgage loans and sell them to investors. We may be required to repurchase mortgage loans that have been sold to investors in the event there are breaches of certain representations and warranties contained within the sales agreements. We may be required to repurchase mortgage loans that were sold to investors in the event that there was inadequate underwriting or fraud, or in the event that the loans become delinquent shortly after they are originated. We also may be required to indemnify certain purchasers and others against losses they incur in the event of breaches of representations and warranties and in various other circumstances, and the amount of such losses could exceed the repurchase amount of the related loans. Consequently, we may be exposed to credit risk associated with sold loans. Standby letters of credit are irrevocable conditional commitments issued by Stifel Bank to guarantee the performance of a customer to a third party. Financial standby letters of credit are primarily issued to support public and private borrowing arrangements, including commercial paper, bond financing, and similar transactions. Performance standby letters of credit are issued to guarantee performance of certain customers under non-financial contractual obligations. The credit risk involved in issuing standby letters of credit is essentially the same as that involved in extending loans to customers. Should Stifel Bank be obligated to perform under the standby letters of credit, it may seek recourse from the customer for reimbursement of amounts paid. At December 31, 2015 and 2014, Stifel Bank had outstanding letters of credit totaling $38.7 million and $10.4 million, respectively. A majority of the standby letters of credit commitments at December 31, 2015, have expiration terms that are less than one year. Lines of credit are agreements to lend to a customer as long as there is no violation of any condition established in the contract. Lines of credit generally have fixed expiration dates. Stifel Bank uses the same credit policies in granting lines of credit as it does for on-balance sheet instruments. At December 31, 2015 and 2014, Stifel Bank had granted unused lines of credit to commercial and consumer borrowers aggregating $403.2 million and $358.1 million, respectively.

Variable Interest Entities	12 Months Ended
Variable Interest Entities	Dec. 31, 2015
Variable Interest Entity Not Primary Beneficiary Disclosures [Abstract]
Variable Interest Entities	NOTE 28 – Variable Interest Entities Our company’s involvement with VIEs is limited to entities used as investment vehicles and private equity funds, the establishment of Stifel Financial Capital Trusts, and our issuance of a convertible promissory note. We have formed several non-consolidated investment funds with third-party investors that are typically organized as limited liability companies (“LLCs”) or limited partnerships. These partnerships and LLCs have assets of $199.3 million at December 31, 2015. For those funds where we act as the general partner, our company’s economic interest is generally limited to management fee arrangements as stipulated by the fund operating agreements. We have generally provided the third-party investors with rights to terminate the funds or to remove us as the general partner. Management fee revenue earned by our company was insignificant during the years ended December 31, 2015, 2014, and 2013. In addition, our direct investment interest in these entities is insignificant at December 31, 2015 and 2014. Thomas Weisel Capital Management LLC, a subsidiary of our company, acts as the general partner of a series of investment funds in venture capital and fund of funds and manages investment funds that are active buyers of secondary interests in private equity funds, as well as portfolios of direct interests in venture-backed companies. These partnerships have combined assets of $271.1 million at December 31, 2015. We hold variable interests in these funds as a result of our company’s rights to receive management fees. Our company’s investment in and additional capital commitments to the private equity funds are also considered variable interests. The additional capital commitments are subject to call at a later date and are limited in amount. Our exposure to loss is limited to our investments in, advances and commitments to, and receivables due from these funds, and that exposure is insignificant at December 31, 2015. Management fee revenue earned by our company was insignificant during the years ended December 31, 2015, 2014, and 2013. For the entities noted above that were determined to be VIEs, we have concluded that we are not the primary beneficiary, and therefore, we are not required to consolidate these entities. Additionally, for certain other entities, we reviewed other relevant accounting guidance, which states the general partner in a limited partnership is presumed to control that limited partnership. The presumption may be overcome if the limited partners have either: (1) the substantive ability to dissolve the limited partnership or otherwise remove the general partner without cause, or (2) substantive participating rights, which provide the limited partners with the ability to effectively participate in significant decisions that would be expected to be made in the ordinary course of the limited partnership’s business and thereby preclude the general partner from exercising unilateral control over the partnership. If the criteria are not met, the consolidation of the partnership or limited liability company is required. Based on our evaluation of these entities, we determined that these entities do not require consolidation. Debenture to Stifel Financial Capital Trusts We have completed private placements of cumulative trust preferred securities through Stifel Financial Capital Trust II, Stifel Financial Capital Trust III, and Stifel Financial Capital Trust IV (collectively, the “Trusts”). The Trusts are non-consolidated wholly owned business trust subsidiaries of our company and were established for the limited purpose of issuing trust securities to third parties and lending the proceeds to our company. The trust preferred securities represent an indirect interest in junior subordinated debentures purchased from our company by the Trusts, and we effectively provide for the full and unconditional guarantee of the securities issued by the Trusts. We make timely payments of interest to the Trusts as required by contractual obligations, which are sufficient to cover payments due on the securities issued by the Trusts, and believe that it is unlikely that any circumstances would occur that would make it necessary for our company to make payments related to these Trusts other than those required under the terms of the debenture agreements and the trust preferred securities agreements. The Trusts were determined to be VIEs because the holders of the equity investment at risk do not have adequate decision-making ability over the Trust’s activities. Our investment in the Trusts is not a variable interest, because equity interests are variable interests only to the extent that the investment is considered to be at risk. Because our investment was funded by the Trusts, it is not considered to be at risk. Interest in FSI Group, LLC (“FSI”) We have provided financing of $18.0 million in the form of a convertible promissory note to FSI, a limited liability company specializing in investing in banks, thrifts, insurance companies, and other financial services firms. In February 2013, the convertible promissory note was amended and restated. The convertible promissory note matures in April 2018; however, FSI has three five-year extension options. The note is convertible at our election into a 49.9% interest in FSI only after the last extension option. The convertible promissory note has a minimum coupon rate equal to 8% per annum plus additional interest related to certain defined cash flows of the business, not to exceed 18% per annum. As we do not hold the power to direct the activities of FSI nor to absorb a majority of the expected losses, or receive a majority of the expected benefits, it was determined that we are not required to consolidate this entity. Our company’s exposure to loss is limited to the carrying value of the note with FSI at December 31, 2015, of $18.0 million, which is included in other assets in the consolidated statements of financial condition. Our company had no liabilities related to this entity at December 31, 2015. We have the discretion to make additional capital contributions. We have not provided financial or other support to FSI that we were not previously contractually required to provide as of December 31, 2015. Our company’s involvement with FSI has not had a material effect on our consolidated financial position, operations, or cash flows.

Tabular disclosure of the significant judgments and assumptions made in determining whether a variable interest (as defined) held by the entity requires the variable interest entity (VIE) (as defined) to be consolidated and (or) disclose information about its involvement with the VIE, individually or in aggregate (as applicable); the nature of restrictions, if any, on the consolidated VIE's assets and on the settlement of its liabilities reported by an entity in its statement of financial position, including the carrying amounts of such assets and liabilities; the nature of, and changes in, the risks associated with involvement in the VIE; how involvement with the VIE affects the entity's financial position, financial performance, and cash flows; the lack of recourse if creditors (or beneficial interest holders) of the consolidated VIE have no recourse to the general credit of the primary beneficiary (if applicable); the terms of arrangements, giving consideration to both explicit arrangements and implicit variable interests, if any, that could require the entity to provide financial support to the VIE, including events or circumstances that could expose the entity to a loss; the methodology used by the entity for determining whether or not it is the primary beneficiary of the variable interest entity; the significant factors considered and judgments made in determining that the power to direct the activities of a VIE that most significantly impact the VIE's economic performance are shared (as defined); the carrying amounts and classification of assets and liabilities of the VIE included in the statement of financial position; the entity's maximum exposure to loss, if any, as a result of its involvement with the VIE, including how the maximum exposure is determined and significant sources of the entity's exposure to the VIE; a comparison of the carrying amounts of the assets and liabilities and the entity's maximum exposure to loss; information about any liquidity arrangements, guarantees, and (or) other commitments by third parties that may affect the fair value or risk of the entity's variable interest in the VIE; whether or not the entity has provided financial support or other support (explicitly or implicitly) to the VIE that it was not previously contractually required to provide or whether the entity intends to provide that support, including the type and amount of the support and the primary reasons for providing the support; and supplemental information the entity determines necessary to provide.

Subsequent Events [Abstract]
Subsequent Events	NOTE 29 – Subsequent Events We evaluate subsequent events that have occurred after the balance sheet date but before the financial statements are issued. There are two types of subsequent events: (1) recognized, or those that provide additional evidence about conditions that existed at the date of the balance sheet, including the estimates inherent in the process of preparing financial statements, and (2) non-recognized, or those that provide evidence about conditions that did not exist at the date of the balance sheet but arose after that date.

Correction Of Immaterial Misstatement	Dec. 31, 2015
Accounting Changes And Error Corrections [Abstract]
Correction of Immaterial Misstatement	NOTE 30 – Correction of Immaterial Misstatement Subsequent to the issuance of the Company’s 2015 consolidated financial statements, the Company identified a clerical error in the consolidated statement of cash flows for the year ended December 31, 2015. The clerical error resulted in a $52.7 million understatement in increase in other assets and a $52.7 million overstatement of net cash used in operating activities. Management determined that the effect of this clerical error was immaterial and adjusted its consolidated statement of cash flows to correct the amounts for the year ended December 31, 2015. Management also made immaterial adjustments to Note 3 and Note 9.

Nature of Operations and Basis Of Presentation (Policies)	12 Months Ended
	Dec. 31, 2015
Organization Consolidation And Presentation Of Financial Statements [Abstract]
Nature Of Operations	Nature of Operations Stifel Financial Corp. (the “Parent”), through its wholly owned subsidiaries, is principally engaged in retail brokerage; securities trading; investment banking; investment advisory; retail, consumer, and commercial banking; and related financial services. We have offices throughout the United States and several European cities. Our major geographic area of concentration is throughout the United States, with a growing presence in the United Kingdom and Europe. Our company’s principal customers are individual investors, corporations, municipalities, and institutions.
Consolidation Policies	Consolidation Policies The consolidated financial statements include the accounts of Stifel Financial Corp. and its subsidiaries. We also have investments or interests in other entities for which we must evaluate whether to consolidate by determining whether we have a controlling financial interest or are considered to be the primary beneficiary. In determining whether to consolidate these entities, we evaluate whether the entity is a voting interest entity or a variable interest entity (“VIE”).
Voting Interest Entity	Voting Interest Entity. Voting interest entities are entities that have (i) total equity investment at risk sufficient to fund expected future operations independently, and (ii) equity holders who have the obligation to absorb losses or receive residual returns and the right to make decisions about the entity’s activities. We consolidate voting interest entities when we determine that there is a controlling financial interest, usually ownership of all, or a majority of, the voting interest.
Variable Interest Entity	Variable Interest Entity. VIEs are entities that lack one or more of the characteristics of a voting interest entity. We are required to consolidate certain VIEs in which we have the power to direct the activities of the entity and the obligation to absorb significant losses or receive significant benefits. In other cases, we consolidate VIEs when we are deemed to be the primary beneficiary. The primary beneficiary is defined as the entity that has a variable interest, or a combination of variable interests, that maintains control and receives benefits or will absorb losses that are not pro rata with its ownership interests. The determination as to whether an entity is a VIE is based on the structure and nature of the entity. We also consider other characteristics, such as the ability to influence the decision-making relative to the entity’s activities and how the entity is financed. With the exception of entities eligible for the deferral codified in Financial Accounting Standards Board (“FASB”) Accounting Standards Update (“ASU”) No. 2010-10, “Consolidation: Amendments for Certain Investment Funds” (“ASU 2010-10”) (generally asset managers and investment companies), ASC 810 states that a controlling financial interest in an entity is present when an enterprise has a variable interest, or combination of variable interests, that have both the power to direct the activities of the entity that most significantly impact the entity’s economic performance and the obligation to absorb losses of the entity or the rights to receive benefits from the entity that could potentially be significant to the entity. Entities meeting the deferral provision defined by ASU 2010-10 are evaluated under the historical VIE guidance. Under the historical guidance, a controlling financial interest in an entity is present when an enterprise has a variable interest, or combination of variable interests, that will absorb a majority of the entity’s expected losses, receive a majority of the entity’s expected residual returns, or both. The enterprise with a controlling financial interest, known as the primary beneficiary, consolidates the VIE. We determine whether we are the primary beneficiary of a VIE by first performing a qualitative analysis of the VIE’s control structure, expected benefits and losses, and expected residual returns. This analysis includes a review of, among other factors, the VIE’s capital structure, contractual terms, which interests create or absorb benefits or losses, variability, related party relationships, and the design of the VIE. Where a qualitative analysis is not conclusive, we perform a quantitative analysis. We reassess our initial evaluation of an entity as a VIE and our initial determination of whether we are the primary beneficiary of a VIE upon the occurrence of certain reconsideration events. See Note 28 for additional information on VIEs.

Disclosure of accounting policy for consolidation to describe the significant judgments and assumptions made in determining whether a variable interest held by the entity requires the variable interest entity to be consolidated and (or) disclose information about its involvement with the variable interest entity; the methodology used by the entity for determining whether or not it is the primary beneficiary of the variable interest entity; and the significant factors considered and judgments made in determining that the power to direct the activities that significantly impact the economic performance of the variable interest entity are shared (as defined).

Summary Of Significant Accounting Policies (Policies)	12 Months Ended
Summary Of Significant Accounting Policies (Policies)	Dec. 31, 2015
Accounting Policies [Abstract]
Cash and Cash Equivalents	Cash and Cash Equivalents We consider money market mutual funds and highly liquid investments with original maturities of three months or less that are not restricted or segregated to be cash equivalents. Cash and cash equivalents include money market mutual funds, deposits with banks, certificates of deposit, and federal funds sold. Cash and cash equivalents also include balances that Stifel Bank maintains at the Federal Reserve Bank.
Cash Segregated For Regulatory Purposes	Cash Segregated for Regulatory Purposes Our broker-dealer subsidiaries are subject to Rule 15c3-3 under the Securities Exchange Act of 1934, which requires our company to maintain cash or qualified securities in a segregated reserve accounts for the exclusive benefit of its clients. In accordance with Rule 15c3-3, our company has portions of its cash segregated for the exclusive benefit of clients at December 31, 2015.
Brokerage Client Receivables, Net	Brokerage Client Receivables, Net Brokerage client receivables include receivables of our company’s broker-dealer subsidiaries, which represent amounts due on cash and margin transactions and are generally collateralized by securities owned by clients. Brokerage client receivables, primarily consisting of floating-rate loans collateralized by customer-owned securities, are charged interest at rates similar to other such loans made throughout the industry. The receivables are reported at their outstanding principal balance net of allowance for doubtful accounts. When a brokerage client receivable is considered to be impaired, the amount of the impairment is generally measured based on the fair value of the securities acting as collateral, which is measured based on current prices from independent sources, such as listed market prices or broker-dealer price quotations. Securities owned by customers, including those that collateralize margin or other similar transactions, are not reflected in the consolidated statements of financial condition.
Securities Borrowed and Securities Loaned	Securities Borrowed and Securities Loaned Securities borrowed require our company to deliver cash to the lender in exchange for securities and are included in receivables from brokers, dealers, and clearing organizations in the consolidated statements of financial condition. For securities loaned, we generally receive collateral in the form of cash in an amount in excess of the market value of securities loaned. Securities loaned are included in payables to brokers, dealers, and clearing organizations in the consolidated statements of financial condition. We monitor the market value of securities borrowed and loaned on a daily basis, with additional collateral obtained or refunded as necessary. Fees received or paid are recorded in interest revenue or interest expense. Substantially all of these transactions are executed under master netting agreements, which gives us right of offset in the event of counterparty default; however, such receivables and payables with the same counterparty are not set-off in the consolidated statements of financial condition.
Securities Purchased Under Agreements to Resell and Repurchase Agreements	Securities Purchased Under Agreements to Resell and Repurchase Agreements Securities purchased under agreements to resell (“resale agreements”) are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. We obtain control of collateral with a market value equal to or in excess of the principal amount loaned and accrued interest under resale agreements. These agreements are short-term in nature and are collateralized by U.S. government agency securities. We value collateral on a daily basis, with additional collateral obtained when necessary to minimize the risk associated with this activity. Securities sold under agreements to repurchase (“repurchase agreements”) are collateralized financing transactions that are recorded at their contractual amounts plus accrued interest. We make delivery of securities sold under agreements to repurchase and monitor the value of collateral on a daily basis. When necessary, we will deliver additional collateral.
Financial Instruments	Financial Instruments We measure certain financial assets and liabilities at fair value on a recurring basis, including cash equivalents, financial instruments owned, available-for-sale securities, investments, financial instruments sold, but not yet purchased, and derivatives. Other than those separately discussed in the notes to the consolidated financial statements, the remaining financial instruments are generally short-term in nature, and their carrying values approximate fair value. The fair value of a financial instrument is defined as the price that would be received to sell an asset or paid to transfer a liability (i.e., “the exit price”) in an orderly transaction between market participants at the measurement date. We have categorized our financial instruments measured at fair value into a three-level classification in accordance with Topic 820, “Fair Value Measurement,” which established a hierarchy for inputs used in measuring fair value that maximizes the use of observable inputs and minimizes the use of unobservable inputs by requiring that the most observable inputs be used when available. Observable inputs are inputs that market participants would use in pricing the asset or liability developed based on market data obtained from independent sources. Unobservable inputs reflect our assumptions that market participants would use in pricing the asset or liability developed based on the best information available in the circumstances. The hierarchy is broken down into three levels based on the transparency of inputs as follows: Level 1 – Quoted prices (unadjusted) are available in active markets for identical assets or liabilities as of the measurement date. A quoted price for an identical asset or liability in an active market provides the most reliable fair value measurement, because it is directly observable to the market. Level 2 – Pricing inputs are other than quoted prices in active markets, which are either directly or indirectly observable as of the measurement date. The nature of these financial instruments includes instruments for which quoted prices are available but traded less frequently, derivative instruments whose fair value have been derived using a model where inputs to the model are directly observable in the market, or can be derived principally from or corroborated by observable market data, and instruments that are fair valued using other financial instruments, the parameters of which can be directly observed. Level 3 – Instruments that have little to no pricing observability as of the measurement date. These financial instruments do not have two-way markets and are measured using management’s best estimate of fair value, where the inputs into the determination of fair value require significant management judgment or estimation. Valuation of Financial Instruments When available, we use observable market prices, observable market parameters, or broker or dealer prices (bid and ask prices) to derive the fair value of financial instruments. In the case of financial instruments transacted on recognized exchanges, the observable market prices represent quotations for completed transactions from the exchange on which the financial instrument is principally traded. A substantial percentage of the fair value of our financial instruments owned, available-for-sale securities, investments, and financial instruments sold, but not yet purchased, are based on observable market prices, observable market parameters, or derived from broker or dealer prices. The availability of observable market prices and pricing parameters can vary from product to product. Where available, observable market prices and pricing or market parameters in a product may be used to derive a price without requiring significant judgment. In certain markets, observable market prices or market parameters are not available for all products, and fair value is determined using techniques appropriate for each particular product. These techniques involve some degree of judgment. For investments in illiquid or privately held securities that do not have readily determinable fair values, the determination of fair value requires us to estimate the value of the securities using the best information available. Among the factors we consider in determining the fair value of investments are the cost of the investment, terms and liquidity, developments since the acquisition of the investment, the sales price of recently issued securities, the financial condition and operating results of the issuer, earnings trends and consistency of operating cash flows, the long-term business potential of the issuer, the quoted market price of securities with similar quality and yield that are publicly traded, and other factors generally pertinent to the valuation of investments. In instances where a security is subject to transfer restrictions, the value of the security is based primarily on the quoted price of a similar security without restriction but may be reduced by an amount estimated to reflect such restrictions. The fair value of these investments is subject to a high degree of volatility and may be susceptible to significant fluctuation in the near term, and the differences could be material. The degree of judgment used in measuring the fair value of financial instruments generally correlates to the level of pricing observability. Pricing observability is impacted by a number of factors, including the type of financial instrument, whether the financial instrument is new to the market and not yet established, and the characteristics specific to the transaction. Financial instruments with readily available active quoted prices for which fair value can be measured from actively quoted prices generally will have a higher degree of pricing observability and a lesser degree of judgment used in measuring fair value. Conversely, financial instruments rarely traded or not quoted will generally have less, or no, pricing observability and a higher degree of judgment used in measuring fair value. See Note 6 for additional information on how we value our financial instruments.
Available-for-Sale and Held-to-Maturity Securities	Available-for-Sale and Held-to-Maturity Securities Securities available for sale include U.S. government agency securities; state and municipal securities; agency, non-agency, and commercial mortgage-backed securities; corporate fixed income securities; and asset-backed securities. Securities held to maturity are recorded at amortized cost based on our company’s positive intent and ability to hold these securities to maturity. Securities held to maturity include agency and commercial mortgage-backed securities, asset-backed securities, consisting of collateralized loan obligation securities and ARS, and corporate fixed income securities. We evaluate all securities in an unrealized loss position quarterly to assess whether the impairment is other-than-temporary on a quarterly basis. Our other-than-temporary impairment (“OTTI”) assessment is a subjective process requiring the use of judgments and assumptions. Accordingly, we consider a number of qualitative and quantitative criteria in our assessment, including the extent and duration of the impairment, recent events specific to the issuer and/or industry to which the issuer belongs, the payment structure of the security, external credit ratings and the failure of the issuer to make scheduled interest or principal payments, the value of underlying collateral, current market conditions, and our company’s ability and intent to hold the investment until its value recovers or the securities mature. We may determine that the decline in fair value of an investment is other-than-temporary if our analysis of these factors indicates that we will not recover our investment in the securities. If we determine that impairment on our debt securities is other-than-temporary and we have made the decision to sell the security or it is more likely than not that we will be required to sell the security prior to recovery of its amortized cost basis, we recognize the entire portion of the impairment in earnings. If we have not made a decision to sell the security and we do not expect that we will be required to sell the security prior to recovery of the amortized cost basis, we recognize only the credit component of OTTI in other income in the consolidated statements of operations. The remaining unrealized loss due to factors other than credit, or the non-credit component, is recorded in accumulated other comprehensive loss. We determine the credit component based on the difference between the security’s amortized cost basis and the present value of its expected future cash flows, discounted based on the purchase yield. The non-credit component represents the difference between the security’s fair value and the present value of expected future cash flows. We estimate the portion of loss attributable to credit using a discounted cash flow model. Key assumptions used in estimating the expected cash flows include default rates, loss severity, and prepayment rates. Assumptions used can vary widely based on the collateral underlying the securities and are influenced by factors such as collateral type, loan interest rate, geographical location of the borrower, and borrower characteristics. Unrealized gains and losses on our available-for-sale securities are reported, net of taxes, in accumulated other comprehensive income included in shareholders’ equity. Amortization of premiums and accretion of discounts are recorded as interest income using the interest method. Realized gains and losses from sales of securities available for sale are determined on a specific identification basis and are included in other revenue in the consolidated statements of operations in the period they are sold.
Loan Classification	Loan Classification We classify loans based on our investment strategy and management’s assessment of our intent and ability to hold loans for the foreseeable future or until maturity. Management’s intent and ability with respect to certain loans may change from time to time depending on a number of factors, including economic, liquidity, and capital conditions. The accounting and measurement framework for loans differs depending on the loan classification. The classification criteria and accounting and measurement framework for bank loans and loans held for sale are described below. Bank Loans and Allowance for Loan Losses Bank loans consist of commercial and residential mortgage loans, home equity loans, stock-secured loans, construction loans, and commercial and industrial and consumer loans originated or acquired by Stifel Bank. Bank loans include those loans that management has the intent and ability to hold and are recorded at outstanding principal adjusted for any charge-offs, allowance for loan losses, deferred origination fees and costs, and purchased discounts. Loan origination costs, net of fees, are deferred and recognized over the contractual life of the loan as an adjustment of yield using the interest method. Bank loans are generally collateralized by real estate, real property, marketable securities, or other assets of the borrower. Interest income is recognized using the effective interest rate method, which is based upon the respective interest rates and the average daily asset balance. Discount accretion is recognized using the effective interest rate method, which is based upon the respective interest rate and expected lives of loans. We regularly review the loan portfolio and have established an allowance for loan losses for inherent losses estimated to have occurred in the loan portfolio through a provision for loan losses charged to other operating expenses in the consolidated statements of operations. In providing for the allowance for loan losses, we consider historical loss experience, the nature and volume of the loan portfolio, adverse situations that may affect the borrower’s ability to repay, estimated value of any underlying collateral, and prevailing economic conditions. This evaluation is inherently subjective, as it requires estimates that are susceptible to significant revision as more information becomes available. Loans Held for Sale Loans that we intend to sell or for which we do not have the ability and intent to hold for the foreseeable future are classified as held for sale. Loans held for sale consist of fixed-rate and adjustable-rate residential real estate mortgage loans intended for sale. Loans held for sale are stated at lower of cost or market value. Declines in market value below cost and any gains or losses on the sale of these assets are recognized in other revenues in the consolidated statements of operations. Market value is determined based on prevailing market prices for loans with similar characteristics or on sale contract prices. Deferred fees and costs related to these loans are not amortized but are recognized as part of the cost basis of the loan at the time it is sold. Because loans held for sale are reported at lower of cost or market value, an allowance for loan losses is not established for loans held for sale.
Impaired Loans	Impaired Loans A loan is considered impaired when, based on current information and events, it is probable that the scheduled payments of principal or interest when due according to the contractual terms of the loan agreement will not be collectible. Factors considered in determining impairment include payment status, collateral value, and the probability of collecting scheduled principal and interest payments when due. Loans that experience insignificant payment delays and payment shortfalls generally are not classified as impaired. We determine the significance of payment delays and payment shortfalls on a case-by-case basis, taking into consideration all of the circumstances surrounding the loan and the borrower, including the length of the delay, the reasons for the delay, the borrower's prior payment record, and the amount of the shortfall in relation to the principal and interest owed. Once a loan is determined to be impaired, when principal or interest becomes 90 days past due or when collection becomes uncertain, the accrual of interest and amortization of deferred loan origination fees is discontinued (“non-accrual status”) and any accrued and unpaid interest income is reversed. Loans placed on non-accrual status are returned to accrual status when all delinquent principal and interest payments are collected and the collectibility of future principal and interest payments is reasonably assured. Loan losses are charged against the allowance when we believe the uncollectibility of a loan balance is certain. Subsequent recoveries, if any, are credited to the allowance for loan losses. Large groups of smaller balance homogenous loans are collectively evaluated for impairment. Accordingly, we do not separately identify individual consumer and residential loans for impairment measurements. Impairment is measured on a loan-by-loan basis for non-homogeneous loans, and a specific allowance is established for individual loans determined to be impaired. Impairment is measured by comparing the carrying value of the impaired loan to the present value of its expected cash flow discounted at the loan’s effective interest rate, the loan’s observable market price, or the fair value of the collateral if the loan is collateral dependent.
Investments	Investments Our broker-dealer subsidiaries report changes in fair value of marketable and non-marketable securities in other income in the consolidated statements of operations. The fair value of marketable investments is generally based on either quoted market or dealer prices. The fair value of non-marketable securities is based on management’s estimate using the best information available, which generally consists of quoted market prices for similar securities and internally developed discounted cash flow models. Investments in the consolidated statements of financial condition contain investments in securities that are marketable and securities that are not readily marketable. These investments are not included in our broker-dealer trading inventory or available-for-sale or held-to-maturity portfolios and represent the acquiring and disposing of debt or equity instruments for our benefit.
Fixed Assets	Fixed Assets Office equipment is depreciated on an accelerated basis over the estimated useful life of the asset of two to seven years. Leasehold improvements are amortized on a straight-line basis over the lesser of the estimated useful life of the asset or the term of the lease. Buildings and building improvements are amortized on a straight-line basis over the estimated useful life of the asset of three to thirty-nine years. Depreciation expense is recorded in occupancy and equipment rental expense in the consolidated statements of operations. Office equipment, leasehold improvements, and property are stated at cost net of accumulated depreciation and amortization in the consolidated statements of financial condition. Office equipment is reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of such assets may not be recoverable.
Goodwill and Intangible Assets	Goodwill and Intangible Assets Goodwill represents the cost of acquired businesses in excess of the fair value of the related net assets acquired. We test goodwill for impairment on an annual basis and on an interim basis when certain events or circumstances exist. We test for impairment at the reporting unit level, which is generally at the level of or one level below our company’s business segments. For both the annual and interim tests, we have the option to first assess qualitative factors to determine whether the existence of events or circumstances leads to a determination that it is more likely than not that the fair value of a reporting unit is less than its carrying amount. If, after assessing the totality of events or circumstances, we determine it is more likely than not that the fair value of a reporting unit is greater than its carrying amount, then performing the two-step impairment test is not required. However, if we conclude otherwise, we are then required to perform the first step of the two-step impairment test. Goodwill impairment is determined by comparing the estimated fair value of a reporting unit with its respective carrying value. If the estimated fair value exceeds the carrying value, goodwill at the reporting unit level is not deemed to be impaired. If the estimated fair value is below carrying value, however, further analysis is required to determine the amount of the impairment. Additionally, if the carrying value of a reporting unit is zero or a negative value and it is determined that it is more likely than not the goodwill is impaired, further analysis is required. The estimated fair values of the reporting units are derived based on valuation techniques we believe market participants would use for each of the reporting units. We have elected July 31 as our annual impairment testing date. Identifiable intangible assets, which are amortized over their estimated useful lives, are tested for potential impairment whenever events or changes in circumstances suggest that the carrying value of an asset or asset group may not be fully recoverable.
Loan And Advances	Loans and Advances We offer transition pay, principally in the form of upfront loans, to financial advisors and certain key revenue producers as part of our company’s overall growth strategy. These loans are generally forgiven by a charge to compensation and benefits over a five- to ten-year period if the individual satisfies certain conditions, usually based on continued employment and certain performance standards. We monitor and compare individual financial advisor production to each loan issued to ensure future recoverability. If the individual leaves before the term of the loan expires or fails to meet certain performance standards, the individual is required to repay the balance. In determining the allowance for doubtful receivables from former employees, management considers the facts and circumstances surrounding each receivable, including the amount of the unforgiven balance, the reasons for the terminated employment relationship, and the former employees’ overall financial situation.
Derivative Instruments And Hedging Activities	Derivative Instruments and Hedging Activities We recognize all of our derivative instruments at fair value as either assets or liabilities in the consolidated statements of financial condition. These instruments are recorded in other assets or accounts payable and accrued expenses in the consolidated statements of financial condition and in the operating section of the consolidated statements of cash flows as increases or decreases of other assets and accounts payable and accrued expenses. Our company’s policy is not to offset fair value amounts recognized for derivative instruments and fair value amounts recognized for the right to reclaim cash collateral or the obligation to return cash collateral arising from derivative instruments recognized at fair value executed with the same counterparty under master netting arrangements. The accounting for changes in the fair value (i.e., gains and losses) of a derivative instrument depends on whether it has been designated and qualifies as part of a hedging relationship and, further, on the type of hedging relationship. For those derivative instruments that are designated and qualify as hedging instruments under Topic 815, “Derivatives and Hedging,” we must also designate the hedging instrument or transaction, based upon the exposure being hedged. For derivative instruments that are designated and qualify as cash flow hedges (i.e., hedging the exposure to variability in expected future cash flows that is attributable to a particular risk), the effective portion of the gain or loss on the derivative instrument is reported as a component of accumulated other comprehensive income, net of tax, and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. The remaining gain or loss on the derivative instrument in excess of the cumulative change in the present value of future cash flows of the hedged item, if any, is recognized in current earnings during the period of change. We do not use derivatives for trading or speculative purposes and, at December 31, 2015, do not have any derivatives that are not designated in qualifying cash flow hedging relationships. See Note 15 for additional details.
Revenue Recognition	Revenue Recognition Customer securities transactions are recorded on a settlement date basis, with related commission revenues and expenses recorded on a trade date basis. Commission revenues are recorded as the amount charged to the customer, which, in certain cases, may include varying discounts. Principal securities transactions are recorded on a trade date basis. We typically distribute our proprietary equity research products to our client base of institutional investors at no charge. These proprietary equity research products are accounted for as a cost of doing business. Investment banking revenues, which include underwriting fees, management fees, advisory fees, and sales credits earned in connection with the distribution of the underwritten securities, are recorded when services for the transactions are completed under the terms of each engagement. Expenses associated with such transactions are deferred until the related revenue is recognized or the engagement is otherwise concluded. Investment banking revenues are presented net of related unreimbursed expenses. Expenses related to investment banking deals not completed are recognized as non-interest expenses in the consolidated statements of operations. For the periods presented, there were no significant expenses recognized for incomplete transactions. We have not recognized any incentive income that is subject to contingent repayments. Asset management and service fees are recorded when earned, based on the period-end assets in the accounts, and consist of customer account service fees, per account fees (such as IRA fees), and wrap fees on managed accounts. We earn fees from the investment partnerships that we manage or of which we are a general partner. Such management fees are generally based on the net assets or committed capital of the underlying partnerships. We have agreed, in certain cases, to waive management fees, in lieu of making a cash contribution, in satisfaction of our general partner investment commitments to the investment partnerships. In these cases, we generally recognize our management fee revenues at the time when we are allocated a special profit interest in realized gains from these partnerships.
Direct Financing And Operating Leases	Operating Leases We lease office space and equipment under operating leases. We recognize rent expense related to these operating leases on a straight-line basis over the lease term. The lease term commences on the earlier of the date when we become legally obligated for the rent payments or the date on which we take possession of the property. For tenant improvement allowances and rent holidays, we record a deferred rent liability in accounts payable and accrued expenses in the consolidated statements of financial condition and amortize the deferred rent over the lease term as a reduction to occupancy and equipment rental expense in the consolidated statements of operations.
Income Taxes	Income Taxes We compute income taxes using the asset and liability method, under which deferred income taxes are provided for the temporary differences between the financial statement carrying amounts and the tax basis of our company’s assets and liabilities. We establish a valuation allowance for deferred tax assets if it is more likely than not that these items will either expire before we are able to realize their benefits, or that future deductibility is uncertain. We recognize the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the taxing authorities, based on the technical merits of the position. The tax benefits recognized in the consolidated financial statements from such a position are measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. We recognize interest and penalties related to uncertain tax positions in provision for income taxes/(benefit) in the consolidated statements of operations. See Note 24 for further information regarding income taxes.
Foreign Currency Translation	Foreign Currency Translation We consolidate our foreign subsidiaries, which have designated their local currency as their functional currency. Assets and liabilities of these foreign subsidiaries are translated at year-end rates of exchange. Revenues and expenses are translated at an average rate for the period. In accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification Topic 830, “Foreign Currency Matters,” gains or losses resulting from translating foreign currency financial statements are reflected in accumulated other comprehensive income, a separate component of shareholders’ equity. Gains or losses resulting from foreign currency transactions are included in net income.
Recently Adopted Accounting Guidance	Recently Adopted Accounting Guidance Business Combinations In September 2015, the Financial Accounting Standards Board (“FASB”) issued Accounting Standard Update (“ASU”) No. 2015-16, Business Combinations (Topic 805): "Simplifying the Accounting for Measurement-Period Adjustments" (“ASU 2015-16”), which eliminates the requirement for an acquirer in a business combination to account for measurement-period adjustments retrospectively. Under this ASU, acquirers must recognize measurement-period adjustments in the period in which they determine the amounts, including the effect on earnings of any amounts they would have recorded in previous periods if the accounting had been completed at the acquisition date. This guidance is effective for fiscal years beginning after December 15, 2016, with early adoption permitted. We elected to early adopt this ASU in the third quarter of 2015. The adoption of ASU 2015-16 did not have a material impact on our consolidated financial statements. Disclosures for Investments in Certain Entities That Calculate Net Asset Value Per Share In May 2015, the FASB issued ASU No. 2015-07, “Fair Value Measurement (Topic 820): Disclosures for Investments in Certain Entities That Calculate Net Asset Value Per Share (or Its Equivalent).” The guidance removes the requirement to categorize within the fair value hierarchy all investments for which fair value is measured using the net asset value per share practical expedient. The guidance also removes the requirement to make certain disclosures for all investments that are eligible to be measured at fair value using the net asset value per share practical expedient. Rather, those disclosures are limited to investments for which the entity has elected to measure the fair value using that practical expedient. The guidance is effective for fiscal years beginning after December 15, 2015, and for interim periods within those years. The guidance shall be applied retrospectively for all periods presented. Early application is permitted. The guidance is not expected to have a material impact on our consolidated financial statements. Interest - Imputation of Interest In April 2015, the FASB issued ASU No. 2015-03, “Interest - Imputation of Interest (Subtopic 835-30): Simplifying the Presentation of Debt Issuance Costs” (“ASU 2015-03”). The guidance in ASU 2015-03 requires that debt issuance costs related to a recognized debt liability be presented in the balance sheet as a direct deduction from the carrying amount of that debt liability, consistent with debt discounts. ASU 2015-03 is effective for fiscal years beginning after December 15, 2015, and interim periods within those fiscal years. Early adoption is permitted, and a retrospective approach is required. The guidance is not expected to have a material impact on our consolidated financial statements. Consolidation In February 2015, the FASB issued ASU No. 2015-02, “Consolidation (Topic 810): Amendments to the Consolidation Analysis” that amends the criteria for determining whether limited partnerships and similar entities are VIEs, clarifies when a general partner or asset manager should consolidate an entity, and eliminates the indefinite deferral of certain aspects of VIE accounting guidance for investments in certain investment funds. Money market funds registered under Rule 2a-7 of the Investment Company Act and similar funds are exempt from consolidation under the new guidance. The new accounting guidance is effective beginning on January 1, 2016. Early adoption is permitted. We elected to early adopt this ASU in 2015. The adoption of ASU 2015-02 did not have a material impact on our consolidated financial statements. Repurchase Agreements In June 2014, the FASB issued ASU No. 2014-11, "Transfers and Servicing (Topic 860): Repurchase-to-Maturity Transactions, Repurchase Financings, and Disclosures," ("ASU 2014-11") amending FASB Accounting Standards Codification Topic 860, "Transfers and Servicing." The amended guidance changes the accounting for repurchase-to-maturity transactions and repurchase financing arrangements. The guidance also requires new disclosures for certain transfers accounted for as sales and collateral supporting transactions that are accounted for as secured borrowings. ASU 2014-11 is effective for annual and interim periods beginning after December 15, 2014, except for the disclosures related to secured borrowings, which are effective for annual periods beginning after December 15, 2014, and for interim periods beginning after March 15, 2015. The adoption of ASU 2014-11 did not have a material impact on our results of operations or financial position. Revenue Recognition In May 2014, the FASB issued ASU No. 2014-09, "Revenue From Contracts with Customers (Topic 606)," ("ASU 2014-09") which supersedes current revenue recognition guidance, including most industry-specific guidance. ASU 2014-09 requires a company to recognize revenue when it transfers promised goods or services to customers in an amount that reflects the consideration to which the company expects to be entitled in exchange for those goods and services. The guidance also requires additional disclosures regarding the nature, amount, timing, and uncertainty of revenue that is recognized. The FASB has approved a one-year deferral of this standard, and this pronouncement is now effective for annual reporting periods beginning after December 15, 2017, including interim periods within that reporting period, and is to be applied using one of two retrospective application methods, with early application not permitted. We are currently evaluating the impact the new guidance will have on our consolidated financial statements. Discontinued Operations In April 2014, the FASB issued ASU No. 2014-08, “Presentation of Financial Statements (Topic 205) and Property, Plant, and Equipment (Topic 360): Reporting Discontinued Operations and Disclosures of Disposals of Components of an Entity,” (“ASU 2014-08”) amending FASB ASC Topic 205-20, “Discontinued Operations,” (“ASC 205-20”). The amended guidance changes the criteria for reporting discontinued operations and requires new disclosures. ASU 2014-08 is effective for annual and interim periods beginning on or after December 15, 2014, and will be applied prospectively. The adoption of ASU 2014-08 did not have a material impact on our consolidated financial statements.
