Performance: The Bottom Line

Average annual total return reflects the change in the value of an investment, assuming reinvestment of distributions from dividend income and capital gains (the profits earned upon the sale of securities that have grown in value, if any) and assuming a constant rate of performance each year. The hypothetical investment and the average annual total returns do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. During periods of reimbursement by Fidelity, a fund’s total return will be greater than it would be had the reimbursement not occurred. How a fund did yesterday is no guarantee of how it will do tomorrow.

Management's Discussion of Fund Performance

Market Recap:  The U.S. equity bellwether S&P 500^® index gained 7.99% for the 12 months ending July 31, 2019, beginning the new year on a high note after enduring a historically volatile final quarter of 2018. Upbeat company earnings/outlooks and signs the Federal Reserve may pause on rates boosted stocks to an all-time high on April 30. In May, however, volatility spiked and stocks returned -6.35% for the month amid the Fed’s decision to hold interest rates steady and signal that it had little appetite to adjust them any time soon, as well as retaliatory tariffs imposed on the U.S. by China. The downtrend was similar to late 2018, when many investors fled from risk assets on elevated concerns about future economic growth, global trade and tighter monetary policy. The bull market roared back in June, with the S&P 500^® rising 7.05%, and recorded a series of all-time highs in a productive July (+1.44%). For the full 12 months, growth stocks outpaced value, while large-caps handily bested small-caps. By sector, information technology (+19%) led the way, boosted by continued strength in software & services (+26%), the market’s largest industry segment. Three defensive groups also stood out – real estate (+18%), utilities (+17%) and consumer staples (+15%) – followed by consumer discretionary (+10%) and communication services (+8%). In contrast, energy (-16%) was by far the weakest sector. Other notable laggards included materials (0%), financials (+3%), industrials (+4%) and health care (+4%). Comments from the Geode Capital Management, LLC, commodity team:  For the fiscal year, the fund returned -5.84%, trailing the -5.36% result of the benchmark Bloomberg Commodity Index Total Return℠. The fund's strategy aims to provide broad-based exposure to commodities via commodity-linked futures/swaps or structured notes. The past 12 months, exposure to energy commodities meaningfully detracted from performance versus the benchmark. Relatively warm winter conditions in the U.S. weighed on demand for natural gas (-19%) while domestic production remained strong. WTI crude oil fell -14%; much of this decline came in the fourth quarter, as slower demand and higher supply drove down the commodity price. Agriculture commodities were generally weak, as often-high supply coupled with U.S.–China trade tension helped push down prices. Soybeans returned roughly -10%, while wheat and corn prices returned -17% and about -3%, respectively. Trade tension and a weakening global economic outlook weighed on certain industrial metals, including copper (-5%) and aluminum (-15%). Nickel and zinc gained roughly 4% and 2%, respectively, reflecting falling inventories for these metals. In the precious metals sector, gold (+16%) and silver (+4%) were driven by concerns about global economic performance underscored by trade tension and accommodative central banks. In the livestock sector, lean hogs gained 7%, partly driven by the supply-and-demand effects of African swine fever in China, the world's largest producer and consumer and pork. Live cattle prices rose 2%, reflecting strong demand for beef.

Notes to Consolidated Financial Statements

For the period ended July 31, 2019

1. Organization.

Fidelity Series Commodity Strategy Fund (the Fund) is a fund of Fidelity Oxford Street Trust (the Trust) and is authorized to issue an unlimited number of shares. Shares of the Fund are only available for purchase by mutual funds for which Fidelity Management & Research Company (FMR) or an affiliate serves as an investment manager. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. Effective August 28, 2017, the Fund no longer offered Class F, and all outstanding shares of Class F were exchanged for shares of Series Commodity Strategy.

2. Consolidated Subsidiary.

The Fund invests in certain commodity-related investments through Geode Series Commodity Return Cayman Ltd., a wholly owned subsidiary (the "Subsidiary"). As of period end, the Fund held an investment of $654,931,087 in the Subsidiary, representing 9.0% of the Fund's net assets.

The financial statements have been consolidated and include accounts of the Fund and the Subsidiary. Accordingly, all inter-company transactions and balances have been eliminated.

3. Investments in Fidelity Central Funds.

The Fund invests in Fidelity Central Funds, which are open-end investment companies generally available only to other investment companies and accounts managed by FMR and its affiliates. The Fund's Consolidated Schedule of Investments lists each of the Fidelity Central Funds held as of period end, if any, as an investment of the Fund, but does not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, the Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.

The Money Market Central Funds seek preservation of capital and current income and are managed by Fidelity Investments Money Management, Inc. (FIMM), an affiliate of FMR. Annualized expenses of the Money Market Central Funds as of their most recent shareholder report date ranged from less than .005% to .01%.

A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission (the SEC) website at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds, which are not covered by the Fund's Report of Independent Registered Public Accounting Firm, are available on the SEC website or upon request.

4. Significant Accounting Policies.

The Fund is an investment company and applies the accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 Financial Services – Investments Companies. The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the consolidated financial statements. Actual results could differ from those estimates. Subsequent events, if any, through the date that the consolidated financial statements were issued have been evaluated in the preparation of the consolidated financial statements. The following summarizes the significant accounting policies of the Fund:

Investment Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. The Board of Trustees (the Board) has delegated the day to day responsibility for the valuation of the Fund's investments to the Fair Value Committee (the Committee) established by the Fund's investment adviser. In accordance with valuation policies and procedures approved by the Board, the Fund attempts to obtain prices from one or more third party pricing vendors or brokers to value its investments. When current market prices, quotations or currency exchange rates are not readily available or reliable, investments will be fair valued in good faith by the Committee, in accordance with procedures adopted by the Board. Factors used in determining fair value vary by investment type and may include market or investment specific events, changes in interest rates and credit quality. The frequency with which these procedures are used cannot be predicted and they may be utilized to a significant extent. The Committee oversees the Fund's valuation policies and procedures and reports to the Board on the Committee's activities and fair value determinations. The Board monitors the appropriateness of the procedures used in valuing the Fund's investments and ratifies the fair value determinations of the Committee.

The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:

• Level 1 – quoted prices in active markets for identical investments
• Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)
• Level 3 – unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value the Fund's investments by major category are as follows:

Debt securities, including restricted securities, are valued based on evaluated prices received from third party pricing vendors or from brokers who make markets in such securities. U.S. government and government agency obligations are valued by pricing vendors who utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. Swaps are marked-to-market daily based on valuations from third party pricing vendors, registered derivatives clearing organizations (clearinghouses) or broker-supplied valuations. These pricing sources may utilize inputs such as movements in the underlying index, interest rate curves, credit spread curves, default possibilities and recovery rates. When independent prices are unavailable or unreliable, debt securities and swaps may be valued utilizing pricing methodologies which consider similar factors that would be used by third party pricing vendors. Debt securities and swaps are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.

Futures contracts are valued at the settlement price or official closing price established each day by the board of trade or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. The aggregate value of investments by input level as of July 31, 2019 is included at the end of the Fund's Consolidated Schedule of Investments.

Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time and includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost. Income and capital gain distributions from Fidelity Central Funds, if any, are recorded on the ex-dividend date. Interest income is accrued as earned and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain.

Expenses. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code, including distributing substantially all of its taxable income and realized gains. As a result, no provision for U.S. Federal income taxes is required. As of July 31, 2019, the Fund did not have any unrecognized tax benefits in the consolidated financial statements; nor is the Fund aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. The Fund files a U.S. federal tax return, in addition to state and local tax returns as required. The Fund's federal income tax returns are subject to examination by the Internal Revenue Service (IRS) for a period of three fiscal years after they are filed. State and local tax returns may be subject to examination for an additional fiscal year depending on the jurisdiction.

The Subsidiary is classified as a controlled foreign corporation under Subchapter N of the Internal Revenue Code. Therefore, the Fund is required to increase its taxable income by its share of the Subsidiary's income. Net investment losses of the Subsidiary cannot be deducted by the Fund in the current period nor carried forward to offset taxable income in future periods.

Distributions are declared and recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

Capital accounts within the consolidated financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Capital accounts are not adjusted for temporary book-tax differences which will reverse in a subsequent period.

Book-tax differences are primarily due to controlled foreign corporations and capital loss carryforwards.

As of period end, the cost and unrealized appreciation (depreciation) in securities, and derivatives if applicable, for federal income tax purposes on an unconsolidated basis were as follows:

Gross unrealized appreciation	$43,202,113
Gross unrealized depreciation	(3,798,360,436)
Net unrealized appreciation (depreciation)	$(3,755,158,323)
Tax cost	$10,943,539,037

The tax-based components of distributable earnings as of period end were as follows:

Undistributed ordinary income	$61,298,678
Capital loss carryforward	$(114,104,407)
Net unrealized appreciation (depreciation) on securities and other investments	$(3,803,425,266)

Capital loss carryforwards are only available to offset future capital gains of the Fund to the extent provided by regulations and may be limited. Under the Regulated Investment Company Modernization Act of 2010 (the Act), the Fund is permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period and such capital losses are required to be used prior to any losses that expire. The capital loss carryforward information presented below, including any applicable limitation, is estimated as of fiscal period end and is subject to adjustment.

No expiration
Short-term	$(85,585,204)
Long-term	(28,519,202)
Total capital loss carryforward	$(114,104,406)

The tax character of distributions paid was as follows:

	July 31, 2019	July 31, 2018
Ordinary Income	$280,564,691	$ 21,654,710

5. Derivative Instruments.

Risk Exposures and the Use of Derivative Instruments. The Fund's investment objective allows the Fund to enter into various types of derivative contracts, including futures contracts and swaps. Derivatives are investments whose value is primarily derived from underlying assets, indices or reference rates and may be transacted on an exchange or over-the-counter (OTC). Derivatives may involve a future commitment to buy or sell a specified asset based on specified terms, to exchange future cash flows at periodic intervals based on a notional principal amount, or for one party to make one or more payments upon the occurrence of specified events in exchange for periodic payments from the other party.

The Fund primarily used derivatives to increase returns, to gain exposure to certain types of assets and to manage exposure to certain risks as defined below. The success of any strategy involving derivatives depends on analysis of numerous economic factors, and if the strategies for investment do not work as intended, the Fund may not achieve its objectives.

The Fund's use of derivatives increased or decreased its exposure to the following risk:

Commodity Risk  Commodity risk is the risk that the value of a commodity will fluctuate as a result of changes in market prices.
 

The Fund is also exposed to additional risks from investing in derivatives, such as liquidity risk and counterparty credit risk. Liquidity risk is the risk that the Fund will be unable to close out the derivative in the open market in a timely manner. Counterparty credit risk is the risk that the counterparty will not be able to fulfill its obligation to the Fund. Derivative counterparty credit risk is managed through formal evaluation of the creditworthiness of all potential counterparties. On certain OTC derivatives such as bi-lateral swaps, the Fund attempts to reduce its exposure to counterparty credit risk by entering into an International Swaps and Derivatives Association, Inc. (ISDA) Master Agreement with each of its counterparties. The ISDA Master Agreement gives the Fund the right to terminate all transactions traded under such agreement upon the deterioration in the credit quality of the counterparty beyond specified levels. The ISDA Master Agreement gives each party the right, upon an event of default by the other party or a termination of the agreement, to close out all transactions traded under such agreement and to net amounts owed under each transaction to one net payable by one party to the other. Upon entering into a swap, the Fund is required to post an initial collateral amount (referred to as "Independent Amount"), as defined in the ISDA Master Agreement. The Fund is required to post additional collateral for the benefit of counterparties to meet the counterparty's unrealized appreciation on outstanding swap contracts and any such posted collateral is identified on the Consolidated Schedule of Investments. To mitigate counterparty credit risk on bi-lateral OTC derivatives, the Fund receives collateral in the form of cash or securities once the Fund's net unrealized appreciation on outstanding derivative contracts under an ISDA Master Agreement exceeds certain applicable thresholds, subject to certain minimum transfer provisions. The collateral received is held in segregated accounts with the Fund's custodian bank in accordance with the collateral agreements entered into between the Fund, the counterparty and the Fund's custodian bank. The Fund could experience delays and costs in gaining access to the collateral even though it is held by the Fund's custodian bank. The Fund's maximum risk of loss from counterparty credit risk related to bi-lateral OTC derivatives is generally the aggregate unrealized appreciation and unpaid counterparty payments in excess of any collateral pledged by the counterparty to the Fund. Exchange-traded futures contracts are not covered by the ISDA Master Agreement; however counterparty credit risk related to exchange-traded futures contracts may be mitigated by the protection provided by the exchange's clearinghouse. A summary of the Fund's derivatives inclusive of potential netting arrangements is presented at the end of the Consolidated Schedule of Investments.

Investing in derivatives may involve greater risks than investing in the underlying assets directly and, to varying degrees, may involve risk of loss in excess of any initial investment and collateral received and amounts recognized in the Consolidated Statement of Assets and Liabilities. In addition, there may be the risk that the change in value of the derivative contract does not correspond to the change in value of the underlying instrument.

Net Realized Gain (Loss) and Change in Net Unrealized Appreciation (Depreciation) on Derivatives. The table below, which reflects the impacts of derivatives on the financial performance of the Fund, summarizes the net realized gain (loss) and change in net unrealized appreciation (depreciation) for derivatives during the period as presented in the Consolidated Statement of Operations.

Primary Risk Exposure / Derivative Type	Net Realized Gain (Loss)	Change in Net Unrealized Appreciation (Depreciation)
Commodity Risk
Futures Contracts	$(105,544,242)	$38,745,877
Swaps	(396,006,848)	44,731,341
Total Commodity Risk	$(501,551,090)	$83,477,218

A summary of the value of derivatives by primary risk exposure as of period end is included at the end of the Consolidated Schedule of Investments.

Futures Contracts. A futures contract is an agreement between two parties to buy or sell a specified underlying instrument for a fixed price at a specified future date. The Fund used futures contracts to manage its exposure to the commodities market.

Upon entering into a futures contract, a fund is required to deposit either cash or securities (initial margin) with a clearing broker in an amount equal to a certain percentage of the face value of the contract. Futures contracts are marked-to-market daily and subsequent daily payments are made or received by a fund depending on the daily fluctuations in the value of the futures contracts and are recorded as unrealized appreciation or (depreciation). This receivable and/or payable, if any, is included in daily variation margin on futures contracts in the Consolidated Statement of Assets and Liabilities. Realized gain or (loss) is recorded upon the expiration or closing of a futures contract. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on futures contracts during the period is presented in the Consolidated Statement of Operations.

Any open futures contracts at period end are presented in the Consolidated Schedule of Investments under the caption "Futures Contracts". The notional amount at value reflects each contract's exposure to the underlying instrument or index at period end. Securities deposited to meet initial margin requirements are identified in the Consolidated Schedule of Investments.

Swaps. A swap is a contract between two parties to exchange future cash flows at periodic intervals based on a notional principal amount. A bi-lateral OTC swap is a transaction between a fund and a dealer counterparty where cash flows are exchanged between the two parties for the life of the swap.

Bi-lateral OTC swaps are marked-to-market daily and changes in value are reflected in the Consolidated Statement of Assets and Liabilities in the bi-lateral OTC swaps at value line items. Any unamortized upfront premiums are presented in the Consolidated Schedule of Investments.

Payments are exchanged at specified intervals, accrued daily commencing with the effective date of the contract and recorded as realized gain or (loss). Some swaps may be terminated prior to the effective date and realize a gain or loss upon termination. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on swaps during the period is presented in the Consolidated Statement of Operations.

Any open swaps at period end are included in the Consolidated Schedule of Investments under the caption "Swaps".

Total Return Swaps. Total return swaps are agreements between counterparties to exchange cash flows, one based on a market-linked return of an individual asset or a basket of assets (i.e., an index), and the other on a fixed or floating rate. To the extent the total return of the instrument or index underlying the transaction exceeds or falls short of the offsetting payment obligation, the Fund will receive a payment from or make a payment to the counterparty. The Fund entered into total return swaps to manage its commodities market exposure.

6. Fees and Other Transactions with Affiliates.

Management Fee and Administration Agreement. Geode Capital Management, LLC (the investment adviser) provides the Fund with investment management related services for which the Fund does not pay a management fee. Under the management contract, the investment adviser pays all ordinary operating expenses of the Fund, except custody fees, fees and expenses of the independent Trustees, and certain miscellaneous expenses such as proxy and shareholder meeting expenses.

FMR provides administrative services to the Fund and the investment adviser pays for these services.

The investment adviser also provides investment management services to the Subsidiary. For the period August 1, 2018 through September 30, 2018, the Subsidiary paid the investment adviser a monthly management fee at an annual rate of .30% of its net assets. Effective October 1, 2018, the Subsidiary no longer paid a monthly management fee. The Subsidiary pays certain operating expenses including custody and directors' fees.

Interfund Trades. The Fund may purchase from or sell securities to other Fidelity Funds under procedures adopted by the Board. The procedures have been designed to ensure these interfund trades are executed in accordance with Rule 17a-7 of the 1940 Act.

7. Committed Line of Credit.

The Fund participates with other funds managed by the investment adviser FMR or an affiliate in a $4.25 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which amounted to $11,691 and is reflected in Commitment fees on the Consolidated Statement of Operations. During the period, the Fund did not borrow on this line of credit.

8. Expense Reductions.

Through arrangements with the Fund's custodian, credits realized as a result of certain uninvested cash balances were used to reduce the Fund's expenses. During the period, these credits reduced the Fund's custody expenses by $4,187.

9. Distributions to Shareholders.

Distributions to shareholders of each class were as follows:

	Year ended July 31, 2019	Year ended July 31, 2018
Distributions to shareholders
Series Commodity Strategy	$280,564,691	$–

Net increase (decrease)	–	(387,564,558)	$–	$(2,026,688,457)

11. Other.

The Fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

At the end of the period, mutual funds managed by FMR or its affiliates were the owners of record of all of the outstanding shares of the Fund.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Fidelity Oxford Street Trust and Shareholders of Fidelity Series Commodity Strategy Fund:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated statement of assets and liabilities, including the consolidated schedule of investments, of Fidelity Series Commodity Strategy Fund and its subsidiary (one of the funds constituting Fidelity Oxford Street Trust, referred to hereafter as the “Fund”) as of July 31, 2019, the related consolidated statement of operations for the year ended July 31, 2019, the consolidated statement of changes in net assets for each of the two years in the period ended July 31, 2019, including the related notes, and the consolidated financial highlights for each of the five years in the period ended July 31, 2019 (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Fund as of July 31, 2019, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period ended July 31, 2019 and the financial highlights for each of the five years in the period ended July 31, 2019 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our procedures included confirmation of securities owned as of July 31, 2019 by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Trustees and Officers

The Trustees, Members of the Advisory Board (if any), and officers of the trust and fund, as applicable, are listed below. The Board of Trustees governs the fund and is responsible for protecting the interests of shareholders. The Trustees are experienced executives who meet periodically throughout the year to oversee the fund's activities, review contractual arrangements with companies that provide services to the fund, oversee management of the risks associated with such activities and contractual arrangements, and review the fund's performance.  Each of the Trustees oversees 274 funds. 

The Trustees hold office without limit in time except that (a) any Trustee may resign; (b) any Trustee may be removed by written instrument, signed by at least two-thirds of the number of Trustees prior to such removal; (c) any Trustee who requests to be retired or who has become incapacitated by illness or injury may be retired by written instrument signed by a majority of the other Trustees; and (d) any Trustee may be removed at any special meeting of shareholders by a two-thirds vote of the outstanding voting securities of the trust.  Each Trustee who is not an interested person (as defined in the 1940 Act) of the trust and the fund is referred to herein as an Independent Trustee.  Each Independent Trustee shall retire not later than the last day of the calendar year in which his or her 75th birthday occurs.  The Independent Trustees may waive this mandatory retirement age policy with respect to individual Trustees.  Officers and Advisory Board Members hold office without limit in time, except that any officer or Advisory Board Member may resign or may be removed by a vote of a majority of the Trustees at any regular meeting or any special meeting of the Trustees. Except as indicated, each individual has held the office shown or other offices in the same company for the past five years. 

The fund’s Statement of Additional Information (SAI) includes more information about the Trustees. To request a free copy, call Fidelity at 1-800-544-8544.

Experience, Skills, Attributes, and Qualifications of the Trustees. The Governance and Nominating Committee has adopted a statement of policy that describes the experience, qualifications, attributes, and skills that are necessary and desirable for potential Independent Trustee candidates (Statement of Policy). The Board believes that each Trustee satisfied at the time he or she was initially elected or appointed a Trustee, and continues to satisfy, the standards contemplated by the Statement of Policy. The Governance and Nominating Committee also engages professional search firms to help identify potential Independent Trustee candidates who have the experience, qualifications, attributes, and skills consistent with the Statement of Policy. From time to time, additional criteria based on the composition and skills of the current Independent Trustees, as well as experience or skills that may be appropriate in light of future changes to board composition, business conditions, and regulatory or other developments, have also been considered by the professional search firms and the Governance and Nominating Committee. In addition, the Board takes into account the Trustees' commitment and participation in Board and committee meetings, as well as their leadership of standing and ad hoc committees throughout their tenure.

In determining that a particular Trustee was and continues to be qualified to serve as a Trustee, the Board has considered a variety of criteria, none of which, in isolation, was controlling. The Board believes that, collectively, the Trustees have balanced and diverse experience, qualifications, attributes, and skills, which allow the Board to operate effectively in governing the fund and protecting the interests of shareholders. Information about the specific experience, skills, attributes, and qualifications of each Trustee, which in each case led to the Board's conclusion that the Trustee should serve (or continue to serve) as a trustee of the fund, is provided below.

Board Structure and Oversight Function. Abigail P. Johnson is an interested person and currently serves as Chairman. The Trustees have determined that an interested Chairman is appropriate and benefits shareholders because an interested Chairman has a personal and professional stake in the quality and continuity of services provided to the fund. Independent Trustees exercise their informed business judgment to appoint an individual of their choosing to serve as Chairman, regardless of whether the Trustee happens to be independent or a member of management. The Independent Trustees have determined that they can act independently and effectively without having an Independent Trustee serve as Chairman and that a key structural component for assuring that they are in a position to do so is for the Independent Trustees to constitute a substantial majority for the Board. The Independent Trustees also regularly meet in executive session. Arthur E. Johnson serves as Chairman of the Independent Trustees and as such (i) acts as a liaison between the Independent Trustees and management with respect to matters important to the Independent Trustees and (ii) with management prepares agendas for Board meetings.

Fidelity^® funds are overseen by different Boards of Trustees. The fund's Board oversees Fidelity's investment-grade bond, money market, asset allocation and certain equity funds, and other Boards oversee Fidelity's high income and other equity funds. The asset allocation funds may invest in Fidelity^® funds that are overseen by such other Boards. The use of separate Boards, each with its own committee structure, allows the Trustees of each group of Fidelity^® funds to focus on the unique issues of the funds they oversee, including common research, investment, and operational issues. On occasion, the separate Boards establish joint committees to address issues of overlapping consequences for the Fidelity^® funds overseen by each Board.

The Trustees operate using a system of committees to facilitate the timely and efficient consideration of all matters of importance to the Trustees, the fund, and fund shareholders and to facilitate compliance with legal and regulatory requirements and oversight of the fund's activities and associated risks.  The Board, acting through its committees, has charged the adviser and FMR and its affiliates with (i) identifying events or circumstances the occurrence of which could have demonstrably adverse effects on the fund's business and/or reputation; (ii) implementing processes and controls to lessen the possibility that such events or circumstances occur or to mitigate the effects of such events or circumstances if they do occur; and (iii) creating and maintaining a system designed to evaluate continuously business and market conditions in order to facilitate the identification and implementation processes described in (i) and (ii) above.  Because the day-to-day operations and activities of the fund are carried out by or through the adviser, FMR and its affiliates, and other service providers, the fund's exposure to risks is mitigated but not eliminated by the processes overseen by the Trustees.  While each of the Board's committees has responsibility for overseeing different aspects of the fund's activities, oversight is exercised primarily through the Operations and Audit Committees.  In addition, an ad hoc Board committee of Independent Trustees has worked with FMR to enhance the Board's oversight of investment and financial risks, legal and regulatory risks, technology risks, and operational risks, including the development of additional risk reporting to the Board.  Appropriate personnel, including but not limited to the fund's Chief Compliance Officer (CCO), FMR's internal auditor, the independent accountants, the fund's Treasurer and portfolio management personnel, make periodic reports to the Board's committees, as appropriate, including an annual review of Fidelity's risk management program for the Fidelity^® funds.  The responsibilities of each standing committee, including their oversight responsibilities, are described further under "Standing Committees of the Trustees."

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs and (2) ongoing costs, including management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (February 1, 2019 to July 31, 2019).

Actual Expenses

The first line of the accompanying table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds.

	Annualized Expense Ratio-A	Beginning Account Value February 1, 2019	Ending Account Value July 31, 2019	Expenses Paid During Period-B February 1, 2019 to July 31, 2019
Series Commodity Strategy	- %-C
Actual		$1,000.00	$985.20	$--D
Hypothetical-E		$1,000.00	$1,024.79	$--D

 ^A Annualized expense ratio reflects consolidated expenses net of applicable fee waivers.

 ^B Expenses are equal to the Fund's annualized expense ratio, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

 ^C Amount represents less than .005%.

 ^D Amount represents less than $.005.

 ^E 5% return per year before expenses

Performance: The Bottom Line

Average annual total return reflects the change in the value of an investment, assuming reinvestment of distributions from dividend income and capital gains (the profits earned upon the sale of securities that have grown in value, if any) and assuming a constant rate of performance each year. The hypothetical investment and the average annual total returns do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. During periods of reimbursement by Fidelity, a fund’s total return will be greater than it would be had the reimbursement not occurred. How a fund did yesterday is no guarantee of how it will do tomorrow.

Management's Discussion of Fund Performance

Market Recap:  The U.S. equity bellwether S&P 500^® index gained 7.99% for the 12 months ending July 31, 2019, beginning the new year on a high note after enduring a historically volatile final quarter of 2018. Upbeat company earnings/outlooks and signs the Federal Reserve may pause on rates boosted stocks to an all-time high on April 30. In May, however, volatility spiked and stocks returned -6.35% for the month amid the Fed’s decision to hold interest rates steady and signal that it had little appetite to adjust them any time soon, as well as retaliatory tariffs imposed on the U.S. by China. The downtrend was similar to late 2018, when many investors fled from risk assets on elevated concerns about future economic growth, global trade and tighter monetary policy. The bull market roared back in June, with the S&P 500^® rising 7.05%, and recorded a series of all-time highs in a productive July (+1.44%). For the full 12 months, growth stocks outpaced value, while large-caps handily bested small-caps. By sector, information technology (+19%) led the way, boosted by continued strength in software & services (+26%), the market’s largest industry segment. Three defensive groups also stood out – real estate (+18%), utilities (+17%) and consumer staples (+15%) – followed by consumer discretionary (+10%) and communication services (+8%). In contrast, energy (-16%) was by far the weakest sector. Other notable laggards included materials (0%), financials (+3%), industrials (+4%) and health care (+4%). Comments from the Geode Capital Management, LLC, commodity team:  For the fiscal year, the fund returned -6.32%, trailing the -5.36% result of the benchmark Bloomberg Commodity Index Total Return℠. The fund's strategy aims to provide broad-based exposure to commodities via commodity-linked futures/swaps or structured notes. The past 12 months, exposure to energy commodities meaningfully detracted from performance versus the benchmark. Relatively warm winter conditions in the U.S. weighed on demand for natural gas (-19%) while domestic production remained strong. WTI crude oil fell -14%; much of this decline came in the fourth quarter, as slower demand and higher supply drove down the commodity price. Agriculture commodities were generally weak, as often-high supply coupled with U.S./China trade tension helped push down prices. Soybeans returned roughly -10%, while wheat and corn prices returned -17% and about -3%, respectively. Trade tension and a weakening global economic outlook weighed on certain industrial metals, including copper (-5%) and aluminum (-15%). Nickel and zinc gained roughly 4% and 2%, respectively, reflecting falling inventories for these metals. In the precious metals sector, gold (+16%) and silver (+4%) were driven by concerns about global economic performance underscored by trade tension and accommodative central banks. In the livestock sector, lean hogs gained 7%, partly driven by the supply-and-demand effects of African swine fever in China, the world's largest producer and consumer and pork. Live cattle prices rose 2%, reflecting strong demand for beef.

Notes to Consolidated Financial Statements

For the period ended July 31, 2019

1. Organization.

Fidelity Commodity Strategy Fund (the Fund) is a non-diversified fund of Fidelity Oxford Street Trust (the Trust) and is authorized to issue an unlimited number of shares. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Massachusetts business trust. Effective September 7, 2018, the Fund no longer offered Class F, and all outstanding shares of Class F were exchanged for shares of Fidelity Commodity Strategy.

2. Consolidated Subsidiary.

The Fund invests in certain commodity-related investments through Geode Commodity Strategy Cayman Ltd., a wholly owned subsidiary (the "Subsidiary"). As of period end, the Fund held an investment of $58,337,894 in the Subsidiary, representing 9.7% of the Fund's net assets.

The financial statements have been consolidated and include accounts of the Fund and the Subsidiary. Accordingly, all inter-company transactions and balances have been eliminated.

3. Investments in Fidelity Central Funds.

The Fund invests in Fidelity Central Funds, which are open-end investment companies generally available only to other investment companies and accounts managed by the investment adviser and its affiliates. The Fund's Consolidated Schedule of Investments lists each of the Fidelity Central Funds held as of period end, if any, as an investment of the Fund, but does not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, the Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.

The Money Market Central Funds seek preservation of capital and current income and are managed by Fidelity Investments Money Management, Inc. (FIMM), an affiliate of the investment adviser. Annualized expenses of the Money Market Central Funds as of their most recent shareholder report date ranged from less than .005% to .01%.

A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission (the SEC) website at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds, which are not covered by the Fund's Report of Independent Registered Public Accounting Firm, are available on the SEC website or upon request.

4. Significant Accounting Policies.

The Fund is an investment company and applies the accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 Financial Services – Investments Companies. The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the consolidated financial statements. Actual results could differ from those estimates. Subsequent events, if any, through the date that the consolidated financial statements were issued have been evaluated in the preparation of the consolidated financial statements. The following summarizes the significant accounting policies of the Fund:

Investment Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. The Board of Trustees (the Board) has delegated the day to day responsibility for the valuation of the Fund's investments to the Fair Value Committee (the Committee) established by the Fund's investment adviser. In accordance with valuation policies and procedures approved by the Board, the Fund attempts to obtain prices from one or more third party pricing vendors or brokers to value its investments. When current market prices, quotations or currency exchange rates are not readily available or reliable, investments will be fair valued in good faith by the Committee, in accordance with procedures adopted by the Board. Factors used in determining fair value vary by investment type and may include market or investment specific events, changes in interest rates and credit quality. The frequency with which these procedures are used cannot be predicted and they may be utilized to a significant extent. The Committee oversees the Fund's valuation policies and procedures and reports to the Board on the Committee's activities and fair value determinations. The Board monitors the appropriateness of the procedures used in valuing the Fund's investments and ratifies the fair value determinations of the Committee.

The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:

• Level 1 – quoted prices in active markets for identical investments
• Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)
• Level 3 – unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value the Fund's investments by major category are as follows:

Debt securities, including restricted securities, are valued based on evaluated prices received from third party pricing vendors or from brokers who make markets in such securities. U.S. government and government agency obligations are valued by pricing vendors who utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. Swaps are marked-to-market daily based on valuations from third party pricing vendors, registered derivatives clearing organizations (clearinghouses) or broker-supplied valuations. These pricing sources may utilize inputs such as movements in the underlying index, interest rate curves, credit spread curves, default possibilities and recovery rates. When independent prices are unavailable or unreliable, debt securities and swaps may be valued utilizing pricing methodologies which consider similar factors that would be used by third party pricing vendors. Debt securities and swaps are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.

Futures contracts are valued at the settlement price or official closing price established each day by the board of trade or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. The aggregate value of investments by input level as of July 31, 2019 is included at the end of the Fund's Consolidated Schedule of Investments.

Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time and includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost. Income and capital gain distributions from Fidelity Central Funds, if any, are recorded on the ex-dividend date. Interest income is accrued as earned and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain.

Class Allocations and Expenses. Investment income, realized and unrealized capital gains and losses, common expenses of the Fund, and certain fund-level expense reductions, if any, are allocated daily on a pro-rata basis to each class based on the relative net assets of each class to the total net assets of the Fund. Each class differs with respect to transfer agent fees incurred. Certain expense reductions may also differ by class. For the reporting period, the allocated portion of income and expenses to each class as a percent of its average net assets may vary due to the timing of recording these transactions in relation to fluctuating net assets of the classes. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code, including distributing substantially all of its taxable income and realized gains. As a result, no provision for U.S. Federal income taxes is required. As of July 31, 2019, the Fund did not have any unrecognized tax benefits in the consolidated financial statements; nor is the Fund aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. The Fund files a U.S. federal tax return, in addition to state and local tax returns as required. The Fund's federal income tax returns are subject to examination by the Internal Revenue Service (IRS) for a period of three fiscal years after they are filed. State and local tax returns may be subject to examination for an additional fiscal year depending on the jurisdiction.

The Subsidiary is classified as a controlled foreign corporation under Subchapter N of the Internal Revenue Code. Therefore, the Fund is required to increase its taxable income by its share of the Subsidiary's income. Net investment losses of the Subsidiary cannot be deducted by the Fund in the current period nor carried forward to offset taxable income in future periods.

Distributions are declared and recorded on the ex-dividend date. Income and capital gain distributions are declared separately for each class. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP.

Capital accounts within the consolidated financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Capital accounts are not adjusted for temporary book-tax differences which will reverse in a subsequent period.

Book-tax differences are primarily due to controlled foreign corporations.

As of period end, the cost and unrealized appreciation (depreciation) in securities, and derivatives if applicable, for federal income tax purposes on an unconsolidated basis were as follows:

Gross unrealized appreciation	$3,289,521
Gross unrealized depreciation	(53,462,568)
Net unrealized appreciation (depreciation)	$(50,173,047)
Tax cost	$640,017,826

The tax-based components of distributable earnings as of period end were as follows:

Undistributed ordinary income	$4,126,241
Net unrealized appreciation (depreciation) on securities and other investments	$(53,298,750)

The tax character of distributions paid was as follows:

	July 31, 2019	July 31, 2018
Ordinary Income	$36,621,149	$ 3,023,258

New Rule Issuance. During August 2018, the U.S. Securities and Exchange Commission issued Final Rule Release No. 33-10532, Disclosure Update and Simplification. This Final Rule includes amendments specific to registered investment companies that are intended to eliminate overlap in disclosure requirements between Regulation S-X and GAAP. In accordance with these amendments, certain line-items in the Fund's consolidated financial statements have been combined or removed for the current period as outlined in the table below.

Financial Statement	Current Line-Item Presentation (As Applicable)	Prior Line-Item Presentation (As Applicable)
Consolidated Statement of Assets and Liabilities	Total distributable earnings (loss)	Undistributed/Distributions in excess of/Accumulated net investment income (loss) Accumulated/Undistributed net realized gain (loss) Net unrealized appreciation (depreciation)

5. Derivative Instruments.

Risk Exposures and the Use of Derivative Instruments. The Fund's investment objective allows the Fund to enter into various types of derivative contracts, including futures contracts and swaps. Derivatives are investments whose value is primarily derived from underlying assets, indices or reference rates and may be transacted on an exchange or over-the-counter (OTC). Derivatives may involve a future commitment to buy or sell a specified asset based on specified terms, to exchange future cash flows at periodic intervals based on a notional principal amount, or for one party to make one or more payments upon the occurrence of specified events in exchange for periodic payments from the other party.

The Fund primarily used derivatives to increase returns, to gain exposure to certain types of assets and to manage exposure to certain risks as defined below. The success of any strategy involving derivatives depends on analysis of numerous economic factors, and if the strategies for investment do not work as intended, the Fund may not achieve its objectives.

The Fund's use of derivatives increased or decreased its exposure to the following risk:

Commodity Risk  Commodity risk is the risk that the value of a commodity will fluctuate as a result of changes in market prices.
 

The Fund is also exposed to additional risks from investing in derivatives, such as liquidity risk and counterparty credit risk. Liquidity risk is the risk that the Fund will be unable to close out the derivative in the open market in a timely manner. Counterparty credit risk is the risk that the counterparty will not be able to fulfill its obligation to the Fund. Derivative counterparty credit risk is managed through formal evaluation of the creditworthiness of all potential counterparties. On certain OTC derivatives such as bi-lateral swaps, the Fund attempts to reduce its exposure to counterparty credit risk by entering into an International Swaps and Derivatives Association, Inc. (ISDA) Master Agreement with each of its counterparties. The ISDA Master Agreement gives the Fund the right to terminate all transactions traded under such agreement upon the deterioration in the credit quality of the counterparty beyond specified levels. The ISDA Master Agreement gives each party the right, upon an event of default by the other party or a termination of the agreement, to close out all transactions traded under such agreement and to net amounts owed under each transaction to one net payable by one party to the other. Upon entering into a swap, the Fund is required to post an initial collateral amount (referred to as "Independent Amount"), as defined in the ISDA Master Agreement. The Fund is required to post additional collateral for the benefit of counterparties to meet the counterparty's unrealized appreciation on outstanding swap contracts and any such posted collateral is identified on the Consolidated Schedule of Investments. To mitigate counterparty credit risk on bi-lateral OTC derivatives, the Fund receives collateral in the form of cash or securities once the Fund's net unrealized appreciation on outstanding derivative contracts under an ISDA Master Agreement exceeds certain applicable thresholds, subject to certain minimum transfer provisions. The collateral received is held in segregated accounts with the Fund's custodian bank in accordance with the collateral agreements entered into between the Fund, the counterparty and the Fund's custodian bank. The Fund could experience delays and costs in gaining access to the collateral even though it is held by the Fund's custodian bank. The Fund's maximum risk of loss from counterparty credit risk related to bi-lateral OTC derivatives is generally the aggregate unrealized appreciation and unpaid counterparty payments in excess of any collateral pledged by the counterparty to the Fund. Exchange-traded futures contracts are not covered by the ISDA Master Agreement; however counterparty credit risk related to exchange-traded futures contracts may be mitigated by the protection provided by the exchange's clearinghouse. A summary of the Fund's derivatives inclusive of potential netting arrangements is presented at the end of the Consolidated Schedule of Investments.

Investing in derivatives may involve greater risks than investing in the underlying assets directly and, to varying degrees, may involve risk of loss in excess of any initial investment and collateral received and amounts recognized in the Consolidated Statement of Assets and Liabilities. In addition, there may be the risk that the change in value of the derivative contract does not correspond to the change in value of the underlying instrument.

Net Realized Gain (Loss) and Change in Net Unrealized Appreciation (Depreciation) on Derivatives. The table below, which reflects the impacts of derivatives on the financial performance of the Fund, summarizes the net realized gain (loss) and change in net unrealized appreciation (depreciation) for derivatives during the period as presented in the Consolidated Statement of Operations.

Primary Risk Exposure / Derivative Type	Net Realized Gain (Loss)	Change in Net Unrealized Appreciation (Depreciation)
Commodity Risk
Futures Contracts	$(4,515,673)	$254,849
Swaps	(43,968,455)	9,522,588
Total Commodity Risk	$(48,484,128)	$9,777,437

A summary of the value of derivatives by primary risk exposure as of period end is included at the end of the Consolidated Schedule of Investments.

Futures Contracts. A futures contract is an agreement between two parties to buy or sell a specified underlying instrument for a fixed price at a specified future date. The Fund used futures contracts to manage its exposure to the commodities market.

Upon entering into a futures contract, a fund is required to deposit either cash or securities (initial margin) with a clearing broker in an amount equal to a certain percentage of the face value of the contract. Futures contracts are marked-to-market daily and subsequent daily payments are made or received by a fund depending on the daily fluctuations in the value of the futures contracts and are recorded as unrealized appreciation or (depreciation). This receivable and/or payable, if any, is included in daily variation margin on futures contracts in the Consolidated Statement of Assets and Liabilities. Realized gain or (loss) is recorded upon the expiration or closing of a futures contract. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on futures contracts during the period is presented in the Consolidated Statement of Operations.

Any open futures contracts at period end are presented in the Consolidated Schedule of Investments under the caption "Futures Contracts". The notional amount at value reflects each contract's exposure to the underlying instrument or index at period end. Securities deposited to meet initial margin requirements are identified in the Consolidated Schedule of Investments.

Swaps. A swap is a contract between two parties to exchange future cash flows at periodic intervals based on a notional principal amount. A bi-lateral OTC swap is a transaction between a fund and a dealer counterparty where cash flows are exchanged between the two parties for the life of the swap.

Bi-lateral OTC swaps are marked-to-market daily and changes in value are reflected in the Consolidated Statement of Assets and Liabilities in the bi-lateral OTC swaps at value line items. Any unamortized upfront premiums are presented in the Consolidated Schedule of Investments.

Payments are exchanged at specified intervals, accrued daily commencing with the effective date of the contract and recorded as realized gain or (loss). Some swaps may be terminated prior to the effective date and realize a gain or loss upon termination. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on swaps during the period is presented in the Consolidated Statement of Operations.

Any open swaps at period end are included in the Consolidated Schedule of Investments under the caption "Swaps".

Total Return Swaps. Total return swaps are agreements between counterparties to exchange cash flows, one based on a market-linked return of an individual asset or a basket of assets (i.e., an index), and the other on a fixed or floating rate. To the extent the total return of the instrument or index underlying the transaction exceeds or falls short of the offsetting payment obligation, the Fund will receive a payment from or make a payment to the counterparty. The Fund entered into total return swaps to manage its commodities market exposure.

6. Fees and Other Transactions with Affiliates.

Management Fee and Administration Agreement. Geode Capital Management, LLC (the investment adviser) provides the Fund with investment management services for which the Fund pays a monthly management fee that is based on an annual rate of .40% of the Fund's average net assets. Under the management contract, the investment adviser pays all other fund-level expenses, except the compensation of the independent Trustees and certain miscellaneous expenses such as proxy and shareholder meeting expenses.

Fidelity Management & Research Company (FMR) provides administrative services to the Fund and the investment adviser pays for these services.

The investment adviser also provides investment management services to the Subsidiary. For the period August 1, 2018 through September 30, 2018, the Subsidiary paid the investment adviser a monthly management fee at an annual rate of .30% of its net assets. Effective October 1, 2018, the Subsidiary no longer paid a monthly management fee. The Subsidiary pays certain operating expenses including custody and directors' fees.

For the reporting period, the total consolidated annual management fee rate which includes the management fee of the Fund and the Subsidiary was .41% of the Fund's average net assets.

During the period, the investment adviser waived a portion of its management fee as described in the Expense Reductions note.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc., (FIIOC), an affiliate of FMR, is the transfer, dividend disbursing and shareholder servicing agent for each class of the Fund. FIIOC receives an asset-based fee of Commodity Strategy's average net assets. FIIOC receives no fees for providing transfer agency services to Class F. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements.

For the period, transfer agent fees for each applicable class were as follows:

	Amount	% of Class-Level Average Net Assets
Commodity Strategy	$827,487	.20

Interfund Trades. The Fund may purchase from or sell securities to other Fidelity Funds under procedures adopted by the Board. The procedures have been designed to ensure these interfund trades are executed in accordance with Rule 17a-7 of the 1940 Act.

7. Expense Reductions.

For the period August 1, 2018 through September 30, 2018, the investment adviser contractually agreed to waive the Fund's management fee in an amount equal to the management fee paid by the Subsidiary. During the period, this waiver reduced the Fund's management fee by $34,333. Effective October 1, 2018, this waiver was discontinued.

In addition, through arrangements with the Fund's custodian, credits realized as a result of certain uninvested cash balances were used to reduce the Fund's expenses. During the period, these credits reduced the Fund's custody expenses by $1,078.

8. Distributions to Shareholders.

Distributions to shareholders of each class were as follows:

10. Other.

The Fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

At the end of the period, mutual funds and accounts managed by FMR or its affiliates were the owners of record of all of the outstanding shares of the Fund.

Report of Independent Registered Public Accounting Firm

To the Board of Trustees of Fidelity Oxford Street Trust and Shareholders of Fidelity Commodity Strategy Fund:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated statement of assets and liabilities, including the consolidated schedule of investments, of Fidelity Commodity Strategy Fund and its subsidiary (one of the funds constituting Fidelity Oxford Street Trust, referred to hereafter as the “Fund”) as of July 31, 2019, the related consolidated statement of operations for the year ended July 31, 2019, the consolidated statement of changes in net assets for each of the two years in the period ended July 31, 2019, including the related notes, and the consolidated financial highlights for each of the two years in the period ended July 31, 2019 and for the period May 30, 2017 (commencement of operations) through July 31, 2017 (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Fund as of July 31, 2019, the results of their operations for the year then ended, the changes in their net assets for each of the two years in the period ended July 31, 2019 and the financial highlights for each of the two years in the period ended July 31, 2019 and for the period May 30, 2017 (commencement of operations) through July 31, 2017 in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements are the responsibility of the Fund’s management. Our responsibility is to express an opinion on the Fund’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits of these consolidated financial statements in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. Our procedures included confirmation of securities owned as of July 31, 2019 by correspondence with the custodian and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audits provide a reasonable basis for our opinion.

Trustees and Officers

The Trustees, Members of the Advisory Board (if any), and officers of the trust and fund, as applicable, are listed below. The Board of Trustees governs the fund and is responsible for protecting the interests of shareholders. The Trustees are experienced executives who meet periodically throughout the year to oversee the fund's activities, review contractual arrangements with companies that provide services to the fund, oversee management of the risks associated with such activities and contractual arrangements, and review the fund's performance.  Each of the Trustees oversees 274 funds. 

The Trustees hold office without limit in time except that (a) any Trustee may resign; (b) any Trustee may be removed by written instrument, signed by at least two-thirds of the number of Trustees prior to such removal; (c) any Trustee who requests to be retired or who has become incapacitated by illness or injury may be retired by written instrument signed by a majority of the other Trustees; and (d) any Trustee may be removed at any special meeting of shareholders by a two-thirds vote of the outstanding voting securities of the trust.  Each Trustee who is not an interested person (as defined in the 1940 Act) of the trust and the fund is referred to herein as an Independent Trustee.  Each Independent Trustee shall retire not later than the last day of the calendar year in which his or her 75th birthday occurs.  The Independent Trustees may waive this mandatory retirement age policy with respect to individual Trustees.  Officers and Advisory Board Members hold office without limit in time, except that any officer or Advisory Board Member may resign or may be removed by a vote of a majority of the Trustees at any regular meeting or any special meeting of the Trustees. Except as indicated, each individual has held the office shown or other offices in the same company for the past five years. 

The fund’s Statement of Additional Information (SAI) includes more information about the Trustees. To request a free copy, call Fidelity at 1-800-544-8544.

Experience, Skills, Attributes, and Qualifications of the Trustees. The Governance and Nominating Committee has adopted a statement of policy that describes the experience, qualifications, attributes, and skills that are necessary and desirable for potential Independent Trustee candidates (Statement of Policy). The Board believes that each Trustee satisfied at the time he or she was initially elected or appointed a Trustee, and continues to satisfy, the standards contemplated by the Statement of Policy. The Governance and Nominating Committee also engages professional search firms to help identify potential Independent Trustee candidates who have the experience, qualifications, attributes, and skills consistent with the Statement of Policy. From time to time, additional criteria based on the composition and skills of the current Independent Trustees, as well as experience or skills that may be appropriate in light of future changes to board composition, business conditions, and regulatory or other developments, have also been considered by the professional search firms and the Governance and Nominating Committee. In addition, the Board takes into account the Trustees' commitment and participation in Board and committee meetings, as well as their leadership of standing and ad hoc committees throughout their tenure.

In determining that a particular Trustee was and continues to be qualified to serve as a Trustee, the Board has considered a variety of criteria, none of which, in isolation, was controlling. The Board believes that, collectively, the Trustees have balanced and diverse experience, qualifications, attributes, and skills, which allow the Board to operate effectively in governing the fund and protecting the interests of shareholders. Information about the specific experience, skills, attributes, and qualifications of each Trustee, which in each case led to the Board's conclusion that the Trustee should serve (or continue to serve) as a trustee of the fund, is provided below.

Board Structure and Oversight Function. Abigail P. Johnson is an interested person and currently serves as Chairman. The Trustees have determined that an interested Chairman is appropriate and benefits shareholders because an interested Chairman has a personal and professional stake in the quality and continuity of services provided to the fund. Independent Trustees exercise their informed business judgment to appoint an individual of their choosing to serve as Chairman, regardless of whether the Trustee happens to be independent or a member of management. The Independent Trustees have determined that they can act independently and effectively without having an Independent Trustee serve as Chairman and that a key structural component for assuring that they are in a position to do so is for the Independent Trustees to constitute a substantial majority for the Board. The Independent Trustees also regularly meet in executive session. Arthur E. Johnson serves as Chairman of the Independent Trustees and as such (i) acts as a liaison between the Independent Trustees and management with respect to matters important to the Independent Trustees and (ii) with management prepares agendas for Board meetings.

Fidelity^® funds are overseen by different Boards of Trustees. The fund's Board oversees Fidelity's investment-grade bond, money market, asset allocation and certain equity funds, and other Boards oversee Fidelity's high income and other equity funds. The asset allocation funds may invest in Fidelity^® funds that are overseen by such other Boards. The use of separate Boards, each with its own committee structure, allows the Trustees of each group of Fidelity^® funds to focus on the unique issues of the funds they oversee, including common research, investment, and operational issues. On occasion, the separate Boards establish joint committees to address issues of overlapping consequences for the Fidelity^® funds overseen by each Board.

The Trustees operate using a system of committees to facilitate the timely and efficient consideration of all matters of importance to the Trustees, the fund, and fund shareholders and to facilitate compliance with legal and regulatory requirements and oversight of the fund's activities and associated risks.  The Board, acting through its committees, has charged the adviser and FMR and its affiliates with (i) identifying events or circumstances the occurrence of which could have demonstrably adverse effects on the fund's business and/or reputation; (ii) implementing processes and controls to lessen the possibility that such events or circumstances occur or to mitigate the effects of such events or circumstances if they do occur; and (iii) creating and maintaining a system designed to evaluate continuously business and market conditions in order to facilitate the identification and implementation processes described in (i) and (ii) above.  Because the day-to-day operations and activities of the fund are carried out by or through the adviser, FMR and its affiliates, and other service providers, the fund's exposure to risks is mitigated but not eliminated by the processes overseen by the Trustees.  While each of the Board's committees has responsibility for overseeing different aspects of the fund's activities, oversight is exercised primarily through the Operations and Audit Committees.  In addition, an ad hoc Board committee of Independent Trustees has worked with FMR to enhance the Board's oversight of investment and financial risks, legal and regulatory risks, technology risks, and operational risks, including the development of additional risk reporting to the Board.  Appropriate personnel, including but not limited to the fund's Chief Compliance Officer (CCO), FMR's internal auditor, the independent accountants, the fund's Treasurer and portfolio management personnel, make periodic reports to the Board's committees, as appropriate, including an annual review of Fidelity's risk management program for the Fidelity^® funds.  The responsibilities of each standing committee, including their oversight responsibilities, are described further under "Standing Committees of the Trustees."

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs and (2) ongoing costs, including management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (February 1, 2019 to July 31, 2019).

Actual Expenses

The first line of the accompanying table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds.

	Annualized Expense Ratio-A	Beginning Account Value February 1, 2019	Ending Account Value July 31, 2019	Expenses Paid During Period-B February 1, 2019 to July 31, 2019
Commodity Strategy	.60%
Actual		$1,000.00	$981.80	$2.95
Hypothetical-C		$1,000.00	$1,021.82	$3.01

 ^A Annualized expense ratio reflects consolidated expenses net of applicable fee waivers.

 ^B Expenses are equal to the Fund's annualized expense ratio, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

 ^C 5% return per year before expenses

Distributions (Unaudited)

The fund hereby designates as a capital gain dividend with respect to the taxable year ended July 31, 2019, $49, or, if subsequently determined to be different, the net capital gain of such year.

Performance: The Bottom Line

Average annual total return reflects the change in the value of an investment, assuming reinvestment of distributions from dividend income and capital gains (the profits earned upon the sale of securities that have grown in value, if any) and assuming a constant rate of performance each year. The hypothetical investment and the average annual total returns do not reflect the deduction of taxes that a shareholder would pay on fund distributions or the redemption of fund shares. During periods of reimbursement by Fidelity, a fund’s total return will be greater than it would be had the reimbursement not occurred. How a fund did yesterday is no guarantee of how it will do tomorrow.

Average annual total returns for Fidelity® SAI Inflation-Focused Fund will be reported once the fund is a year old.

$10,000 Over Life of Fund

Management's Discussion of Fund Performance

Comments from the Geode Capital Management, LLC, commodity team:  From inception on December 20, 2018, through July 31, 2019, the fund gained 3.50%, ahead of the 1.66% advance of the benchmark, the Bloomberg Commodity Index Total Return℠. The fund aims to provide broad-based exposure to commodities via commodity-linked futures/swaps or structured notes. In the energy sector, exposure to natural gas (-36%) was a meaningful detractor during the period, reflecting above-average winter temperatures in the eastern half of the U.S.. Exposure to WTI crude oil (+26%) and Brent crude oil (+23%), however, were both significant positives this period, reflecting tightening supply and geopolitical risk, among other factors. Agriculture commodities were generally weak, as often-high supply coupled with U.S.–China trade tension hampered prices. Soybean prices returned -7%, while wheat prices returned about -8%, partly reflecting export competition from Europe and Russia against the backdrop of a strong U.S. dollar. Corn returned about +2%, as poor spring weather in the U.S. Midwest delayed plantings and increased the probability of yield and acreage loss. Trade tension and a weakening global economic outlook weighed on certain industrial metals, including copper (+0%) and aluminum (-7%). Nickel returned +33%, reflecting falling inventories for the metal. In the precious metals sector, gold (+12%) and silver (+10%) were driven by concerns about global economic performance underscored by trade tension and accommodative central banks. In the livestock sector, lean hogs returned about -6%, as the U.S. hog herd hit a multi-decade high, while live cattle prices returned about -4%, reflecting seasonally high inventory in the U.S. as well as trade tensions. Over the period, Treasury Inflation Protected Securities generally outperformed money market securities.

The views expressed above reflect those of the portfolio manager(s) only through the end of the period as stated on the cover of this report and do not necessarily represent the views of Fidelity or any other person in the Fidelity organization. Any such views are subject to change at any time based upon market or other conditions and Fidelity disclaims any responsibility to update such views. These views may not be relied on as investment advice and, because investment decisions for a Fidelity fund are based on numerous factors, may not be relied on as an indication of trading intent on behalf of any Fidelity fund.

Notes to Consolidated Financial Statements

For the period ended July 31, 2019

1. Organization.

Fidelity SAI Inflation-Focused Fund (the Fund) is a fund of Fidelity Oxford Street Trust (the Trust) and is authorized to issue an unlimited number of shares. Shares are offered exclusively to certain clients of Strategic Advisers LLC or its affiliates. The Trust is registered under the Investment Company Act of 1940, as amended (the 1940 Act), as an open-end management investment company organized as a Delaware statutory trust.

2. Consolidated Subsidiary.

The Fund invests in certain commodity-related investments through Geode SAI Inflation-Focused Cayman Ltd., a wholly owned subsidiary (the "Subsidiary"). As of period end, the Fund held an investment of $179,575,822 in the Subsidiary, representing 14.6% of the Fund's net assets.

The financial statements have been consolidated and include accounts of the Fund and the Subsidiary. Accordingly, all inter-company transactions and balances have been eliminated.

3. Investments in Fidelity Central Funds.

The Fund invests in Fidelity Central Funds, which are open-end investment companies generally available only to other investment companies and accounts managed by the investment adviser and its affiliates. The Fund's Consolidated Schedule of Investments lists each of the Fidelity Central Funds held as of period end, if any, as an investment of the Fund, but does not include the underlying holdings of each Fidelity Central Fund. As an Investing Fund, the Fund indirectly bears its proportionate share of the expenses of the underlying Fidelity Central Funds.

The Money Market Central Funds seek preservation of capital and current income and are managed by Fidelity Investments Money Management, Inc. (FIMM), an affiliate of the investment adviser. Annualized expenses of the Money Market Central Funds as of their most recent shareholder report date ranged from less than .005% to .01%.

A complete unaudited list of holdings for each Fidelity Central Fund is available upon request or at the Securities and Exchange Commission (the SEC) website at www.sec.gov. In addition, the financial statements of the Fidelity Central Funds, which are not covered by the Fund's Report of Independent Registered Public Accounting Firm, are available on the SEC website or upon request.

4. Significant Accounting Policies.

The Fund is an investment company and applies the accounting and reporting guidance of the Financial Accounting Standards Board (FASB) Accounting Standards Codification Topic 946 Financial Services – Investments Companies. The consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (GAAP), which require management to make certain estimates and assumptions at the date of the consolidated financial statements. Actual results could differ from those estimates. Subsequent events, if any, through the date that the consolidated financial statements were issued have been evaluated in the preparation of the consolidated financial statements. The following summarizes the significant accounting policies of the Fund:

Investment Valuation. Investments are valued as of 4:00 p.m. Eastern time on the last calendar day of the period. The Board of Trustees (the Board) has delegated the day to day responsibility for the valuation of the Fund's investments to the Fair Value Committee (the Committee) established by the Fund's investment adviser. In accordance with valuation policies and procedures approved by the Board, the Fund attempts to obtain prices from one or more third party pricing vendors or brokers to value its investments. When current market prices, quotations or currency exchange rates are not readily available or reliable, investments will be fair valued in good faith by the Committee, in accordance with procedures adopted by the Board. Factors used in determining fair value vary by investment type and may include market or investment specific events, changes in interest rates and credit quality. The frequency with which these procedures are used cannot be predicted and they may be utilized to a significant extent. The Committee oversees the Fund's valuation policies and procedures and reports to the Board on the Committee's activities and fair value determinations. The Board monitors the appropriateness of the procedures used in valuing the Fund's investments and ratifies the fair value determinations of the Committee.

The Fund categorizes the inputs to valuation techniques used to value its investments into a disclosure hierarchy consisting of three levels as shown below:

• Level 1 – quoted prices in active markets for identical investments
• Level 2 – other significant observable inputs (including quoted prices for similar investments, interest rates, prepayment speeds, etc.)
• Level 3 – unobservable inputs (including the Fund's own assumptions based on the best information available)

Valuation techniques used to value the Fund's investments by major category are as follows:

Debt securities, including restricted securities, are valued based on evaluated prices received from third party pricing vendors or from brokers who make markets in such securities. U.S. government and government agency obligations are valued by pricing vendors who utilize matrix pricing which considers yield or price of bonds of comparable quality, coupon, maturity and type or by broker-supplied prices. When independent prices are unavailable or unreliable, debt securities may be valued utilizing pricing methodologies which consider similar factors that would be used by third party pricing vendors. Debt securities are generally categorized as Level 2 in the hierarchy but may be Level 3 depending on the circumstances.

Futures contracts are valued at the settlement price or official closing price established each day by the board of trade or exchange on which they are traded and are categorized as Level 1 in the hierarchy. Investments in open-end mutual funds, including the Fidelity Central Funds, are valued at their closing net asset value (NAV) each business day and are categorized as Level 1 in the hierarchy.

Changes in valuation techniques may result in transfers in or out of an assigned level within the disclosure hierarchy. The aggregate value of investments by input level as of July 31, 2019 is included at the end of the Fund's Consolidated Schedule of Investments.

Investment Transactions and Income. For financial reporting purposes, the Fund's investment holdings and NAV include trades executed through the end of the last business day of the period. The NAV per share for processing shareholder transactions is calculated as of the close of business of the New York Stock Exchange (NYSE), normally 4:00 p.m. Eastern time and includes trades executed through the end of the prior business day. Gains and losses on securities sold are determined on the basis of identified cost. Income and capital gain distributions from Fidelity Central Funds, if any, are recorded on the ex-dividend date. Interest income is accrued as earned and includes coupon interest and amortization of premium and accretion of discount on debt securities as applicable. Investment income is recorded net of foreign taxes withheld where recovery of such taxes is uncertain. The principal amount on inflation-indexed securities is periodically adjusted to the rate of inflation and interest is accrued based on the principal amount. The adjustments to principal due to inflation are reflected as increases or decreases to Interest in the accompanying Consolidated Statement of Operations.

Expenses. Expenses directly attributable to a fund are charged to that fund. Expenses attributable to more than one fund are allocated among the respective funds on the basis of relative net assets or other appropriate methods. Expense estimates are accrued in the period to which they relate and adjustments are made when actual amounts are known.

Income Tax Information and Distributions to Shareholders. Each year, the Fund intends to qualify as a regulated investment company under Subchapter M of the Internal Revenue Code, including distributing substantially all of its taxable income and realized gains. As a result, no provision for U.S. Federal income taxes is required. As of July 31, 2019, the Fund did not have any unrecognized tax benefits in the consolidated financial statements; nor is the Fund aware of any tax positions for which it is reasonably possible that the total amounts of unrecognized tax benefits will significantly change in the next twelve months. The Fund files a U.S. federal tax return, in addition to state and local tax returns as required. The Fund's federal income tax returns are subject to examination by the Internal Revenue Service (IRS) for a period of three fiscal years after they are filed. State and local tax returns may be subject to examination for an additional fiscal year depending on the jurisdiction.

The Subsidiary is classified as a controlled foreign corporation under Subchapter N of the Internal Revenue Code. Therefore, the Fund is required to increase its taxable income by its share of the Subsidiary's income. Net investment losses of the Subsidiary cannot be deducted by the Fund in the current period nor carried forward to offset taxable income in future periods.

Distributions are declared and recorded on the ex-dividend date. Income and capital gain distributions are determined in accordance with income tax regulations, which may differ from GAAP. These differences resulted in distribution reclassifications.

Capital accounts within the consolidated financial statements are adjusted for permanent book-tax differences. These adjustments have no impact on net assets or the results of operations. Capital accounts are not adjusted for temporary book-tax differences which will reverse in a subsequent period.

Book-tax differences are primarily due to futures transactions, market discount, controlled foreign corporations, capital loss carryforwards and losses deferred due to wash sales.

As of period end, the cost and unrealized appreciation (depreciation) in securities, and derivatives if applicable, for federal income tax purposes on an unconsolidated basis were as follows:

Gross unrealized appreciation	$30,311,010
Gross unrealized depreciation	(42,148,286)
Net unrealized appreciation (depreciation)	$(11,837,276)
Tax Cost	$1,241,288,112

The tax-based components of distributable earnings as of period end were as follows:

Undistributed ordinary income	$14,982,783
Capital loss carryforward	$(43,287)
Net unrealized appreciation (depreciation) on securities and other investments	$(12,288,291)

Capital loss carryforwards are only available to offset future capital gains of the Fund to the extent provided by regulations and may be limited. Under the Regulated Investment Company Modernization Act of 2010 (the Act), the Fund is permitted to carry forward capital losses incurred in taxable years beginning after December 22, 2010 for an unlimited period and such capital losses are required to be used prior to any losses that expire. The capital loss carryforward information presented below, including any applicable limitation, is estimated as of fiscal period end and is subject to adjustment.

No expiration
Short-term	$(43,287)

The tax character of distributions paid was as follows:

	July 31, 2019(a)
Ordinary Income	$10,000

 (a) For the period December 20, 2018 (commencement of operations) to July 31, 2019.

5. Derivative Instruments.

Risk Exposures and the Use of Derivative Instruments. The Fund's investment objective allows the Fund to enter into various types of derivative contracts, including futures contracts. Derivatives are investments whose value is primarily derived from underlying assets, indices or reference rates and may be transacted on an exchange or over-the-counter (OTC). Derivatives may involve a future commitment to buy or sell a specified asset based on specified terms, to exchange future cash flows at periodic intervals based on a notional principal amount, or for one party to make one or more payments upon the occurrence of specified events in exchange for periodic payments from the other party.

The Fund primarily used derivatives to increase returns and to manage exposure to certain risks as defined below. The success of any strategy involving derivatives depends on analysis of numerous economic factors, and if the strategies for investment do not work as intended, the Fund may not achieve its objectives.

The Fund's use of derivatives increased or decreased its exposure to the following risk:

Commodity Risk  Commodity risk is the risk that the value of a commodity will fluctuate as a result of changes in market prices.
 

The Fund is also exposed to additional risks from investing in derivatives, such as liquidity risk and counterparty credit risk. Liquidity risk is the risk that the Fund will be unable to close out the derivative in the open market in a timely manner. Counterparty credit risk is the risk that the counterparty will not be able to fulfill its obligation to the Fund. Counterparty credit risk related to exchange-traded futures contracts may be mitigated by the protection provided by the exchange's clearinghouse. A summary of the Fund's derivatives inclusive of potential netting arrangements is presented at the end of the Consolidated Schedule of Investments.

Investing in derivatives may involve greater risks than investing in the underlying assets directly and, to varying degrees, may involve risk of loss in excess of any initial investment and collateral received and amounts recognized in the Consolidated Statement of Assets and Liabilities. In addition, there may be the risk that the change in value of the derivative contract does not correspond to the change in value of the underlying instrument.

Futures Contracts. A futures contract is an agreement between two parties to buy or sell a specified underlying instrument for a fixed price at a specified future date. The Fund used futures contracts to manage its exposure to the commodities market.

Upon entering into a futures contract, a fund is required to deposit either cash or securities (initial margin) with a clearing broker in an amount equal to a certain percentage of the face value of the contract. Futures contracts are marked-to-market daily and subsequent daily payments are made or received by a fund depending on the daily fluctuations in the value of the futures contracts and are recorded as unrealized appreciation or (depreciation). This receivable and/or payable, if any, is included in daily variation margin on futures contracts in the Consolidated Statement of Assets and Liabilities. Realized gain or (loss) is recorded upon the expiration or closing of a futures contract. The net realized gain (loss) and change in net unrealized appreciation (depreciation) on futures contracts during the period is presented in the Consolidated Statement of Operations.

Any open futures contracts at period end are presented in the Consolidated Schedule of Investments under the caption "Futures Contracts". The notional amount at value reflects each contract's exposure to the underlying instrument or index at period end. Securities deposited to meet initial margin requirements are identified in the Consolidated Schedule of Investments.

6. Fees and Other Transactions with Affiliates.

Management Fee and Administration Agreement. Geode Capital Management, LLC (the investment adviser) provides the Fund with investment management services for which the Fund pays a monthly management fee that is based on an annual rate of .38% of the Fund's average net assets.

Fidelity Management & Research Company(FMR) provides administrative services to the Fund and the investment adviser pays for these services.

The investment adviser also provides investment management services to the Subsidiary. The Subsidiary does not pay the investment adviser a fee for these services. The Subsidiary pays certain other expenses including custody and directors' fees.

Transfer Agent Fees. Fidelity Investments Institutional Operations Company, Inc. (FIIOC), an affiliate of the investment adviser, is the Fund's transfer, dividend disbursing and shareholder servicing agent. FIIOC receives an asset-based fee of .05% of the Fund's average net assets. FIIOC pays for typesetting, printing and mailing of shareholder reports, except proxy statements.

During July 2019, the Board approved that effective August 1, 2019 transfer agent fees will not be paid by the Fund and instead will be paid by the investment adviser or an affiliate.

Accounting Fees. Fidelity Service Company, Inc. (FSC), an affiliate of the investment adviser, maintains the Fund's accounting records. The fee is based on the level of average net assets for each month. For the period, the fees were equivalent to an annualized rate of .04%.

During July 2019, the Board approved that effective August 1, 2019 accounting fees will not be paid by the Fund and instead will be paid by the investment adviser or an affiliate.

Interfund Trades. The Fund may purchase from or sell securities to other Fidelity Funds under procedures adopted by the Board. The procedures have been designed to ensure these interfund trades are executed in accordance with Rule 17a-7 of the 1940 Act.

7. Committed Line of Credit.

The Fund participates with other funds managed by the investment adviser or an affiliate in a $4.25 billion credit facility (the "line of credit") to be utilized for temporary or emergency purposes to fund shareholder redemptions or for other short-term liquidity purposes. The Fund has agreed to pay commitment fees on its pro-rata portion of the line of credit, which amounted to $943 and is reflected in Miscellaneous expenses on the Consolidated Statement of Operations. During the period, the Fund did not borrow on this line of credit.

8. Expense Reductions.

The investment adviser contractually agreed to reimburse the Fund to the extent annual operating expenses exceeded .50% of average net assets. This reimbursement will remain in place through November 30, 2020. Some expenses, for example the compensation of the independent Trustees, and certain miscellaneous expenses such as proxy and shareholder meeting expenses, are excluded from this reimbursement. During the period this reimbursement reduced the Fund's expenses by $80,964.

In addition, through arrangements with the Fund's custodian, credits realized as a result of certain uninvested cash balances were used to reduce the Fund's expenses. During the period, these credits reduced the Fund's custody expenses by $75.

9. Other.

The Fund's organizational documents provide former and current trustees and officers with a limited indemnification against liabilities arising in connection with the performance of their duties to the Fund. In the normal course of business, the Fund may also enter into contracts that provide general indemnifications. The Fund's maximum exposure under these arrangements is unknown as this would be dependent on future claims that may be made against the Fund. The risk of material loss from such claims is considered remote.

Report of Independent Registered Public Accounting Firm

To the Trustees of Fidelity Oxford Street Trust and Shareholders of Fidelity SAI Inflation-Focused Fund:

Opinion on the Financial Statements and Financial Highlights

We have audited the accompanying consolidated statement of assets and liabilities of Fidelity SAI Inflation-Focused Fund and subsidiary (the "Fund"), a fund of Fidelity Oxford Street Trust, including the consolidated schedule of investments, as of July 31, 2019, the related consolidated statement of operations, the consolidated statement of changes in net assets and the consolidated financial highlights for the period from December 20, 2018 (commencement of operations) to July 31, 2019, and the related notes. In our opinion, the consolidated financial statements and consolidated financial highlights present fairly, in all material respects, the financial position of the Fund as of July 31, 2019, and the results of its operations, the changes in its net assets and the financial highlights for the period from December 20, 2018 (commencement of operations) to July 31, 2019, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These consolidated financial statements and consolidated financial highlights are the responsibility of the Fund's management. Our responsibility is to express an opinion on the Fund's consolidated financial statements and consolidated financial highlights based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Fund in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements and financial highlights are free of material misstatement, whether due to error or fraud. The Fund is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audit we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Fund’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audit included performing procedures to assess the risks of material misstatement of the consolidated financial statements and consolidated financial highlights, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements and consolidated financial highlights. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements and consolidated financial highlights. Our procedures included confirmation of securities owned as of July 31, 2019, by correspondence with the custodians and brokers; when replies were not received from brokers, we performed other auditing procedures. We believe that our audit provides a reasonable basis for our opinion.

The Trustees hold office without limit in time except that (a) any Trustee may resign; (b) any Trustee may be removed by written instrument, signed by at least two-thirds of the number of Trustees prior to such removal; (c) any Trustee who requests to be retired or who has become incapacitated by illness or injury may be retired by written instrument signed by a majority of the other Trustees; and (d) any Trustee may be removed at any special meeting of shareholders by a two-thirds vote of the outstanding voting securities of the trust.  Each Trustee who is not an interested person (as defined in the 1940 Act) of the trust and the fund is referred to herein as an Independent Trustee.  Each Independent Trustee shall retire not later than the last day of the calendar year in which his or her 75th birthday occurs.  The Independent Trustees may waive this mandatory retirement age policy with respect to individual Trustees.  Officers and Advisory Board Members hold office without limit in time, except that any officer or Advisory Board Member may resign or may be removed by a vote of a majority of the Trustees at any regular meeting or any special meeting of the Trustees. Except as indicated, each individual has held the office shown or other offices in the same company for the past five years. 

The fund’s Statement of Additional Information (SAI) includes more information about the Trustees. To request a free copy, call Fidelity at 1-800-544-3455.

Experience, Skills, Attributes, and Qualifications of the Trustees. The Governance and Nominating Committee has adopted a statement of policy that describes the experience, qualifications, attributes, and skills that are necessary and desirable for potential Independent Trustee candidates (Statement of Policy). The Board believes that each Trustee satisfied at the time he or she was initially elected or appointed a Trustee, and continues to satisfy, the standards contemplated by the Statement of Policy. The Governance and Nominating Committee also engages professional search firms to help identify potential Independent Trustee candidates who have the experience, qualifications, attributes, and skills consistent with the Statement of Policy. From time to time, additional criteria based on the composition and skills of the current Independent Trustees, as well as experience or skills that may be appropriate in light of future changes to board composition, business conditions, and regulatory or other developments, have also been considered by the professional search firms and the Governance and Nominating Committee. In addition, the Board takes into account the Trustees' commitment and participation in Board and committee meetings, as well as their leadership of standing and ad hoc committees throughout their tenure.

In determining that a particular Trustee was and continues to be qualified to serve as a Trustee, the Board has considered a variety of criteria, none of which, in isolation, was controlling. The Board believes that, collectively, the Trustees have balanced and diverse experience, qualifications, attributes, and skills, which allow the Board to operate effectively in governing the fund and protecting the interests of shareholders. Information about the specific experience, skills, attributes, and qualifications of each Trustee, which in each case led to the Board's conclusion that the Trustee should serve (or continue to serve) as a trustee of the fund, is provided below.

Board Structure and Oversight Function. Abigail P. Johnson is an interested person and currently serves as Chairman. The Trustees have determined that an interested Chairman is appropriate and benefits shareholders because an interested Chairman has a personal and professional stake in the quality and continuity of services provided to the fund. Independent Trustees exercise their informed business judgment to appoint an individual of their choosing to serve as Chairman, regardless of whether the Trustee happens to be independent or a member of management. The Independent Trustees have determined that they can act independently and effectively without having an Independent Trustee serve as Chairman and that a key structural component for assuring that they are in a position to do so is for the Independent Trustees to constitute a substantial majority for the Board. The Independent Trustees also regularly meet in executive session. Arthur E. Johnson serves as Chairman of the Independent Trustees and as such (i) acts as a liaison between the Independent Trustees and management with respect to matters important to the Independent Trustees and (ii) with management prepares agendas for Board meetings.

Fidelity^® funds are overseen by different Boards of Trustees. The fund's Board oversees Fidelity's investment-grade bond, money market, asset allocation and certain equity funds, and other Boards oversee Fidelity's high income and other equity funds. The asset allocation funds may invest in Fidelity^® funds that are overseen by such other Boards. The use of separate Boards, each with its own committee structure, allows the Trustees of each group of Fidelity^® funds to focus on the unique issues of the funds they oversee, including common research, investment, and operational issues. On occasion, the separate Boards establish joint committees to address issues of overlapping consequences for the Fidelity^® funds overseen by each Board.

The Trustees operate using a system of committees to facilitate the timely and efficient consideration of all matters of importance to the Trustees, the fund, and fund shareholders and to facilitate compliance with legal and regulatory requirements and oversight of the fund's activities and associated risks.  The Board, acting through its committees, has charged the adviser and FMR and its affiliates with (i) identifying events or circumstances the occurrence of which could have demonstrably adverse effects on the fund's business and/or reputation; (ii) implementing processes and controls to lessen the possibility that such events or circumstances occur or to mitigate the effects of such events or circumstances if they do occur; and (iii) creating and maintaining a system designed to evaluate continuously business and market conditions in order to facilitate the identification and implementation processes described in (i) and (ii) above.  Because the day-to-day operations and activities of the fund are carried out by or through the adviser, FMR and its affiliates, and other service providers, the fund's exposure to risks is mitigated but not eliminated by the processes overseen by the Trustees.  While each of the Board's committees has responsibility for overseeing different aspects of the fund's activities, oversight is exercised primarily through the Operations and Audit Committees.  In addition, an ad hoc Board committee of Independent Trustees has worked with FMR to enhance the Board's oversight of investment and financial risks, legal and regulatory risks, technology risks, and operational risks, including the development of additional risk reporting to the Board.  Appropriate personnel, including but not limited to the fund's Chief Compliance Officer (CCO), FMR's internal auditor, the independent accountants, the fund's Treasurer and portfolio management personnel, make periodic reports to the Board's committees, as appropriate, including an annual review of Fidelity's risk management program for the Fidelity^® funds.  The responsibilities of each standing committee, including their oversight responsibilities, are described further under "Standing Committees of the Trustees."

Shareholder Expense Example

As a shareholder of the Fund, you incur two types of costs: (1) transaction costs and (2) ongoing costs, including management fees and other Fund expenses. This Example is intended to help you understand your ongoing costs (in dollars) of investing in the Fund and to compare these costs with the ongoing costs of investing in other mutual funds.

The Example is based on an investment of $1,000 invested at the beginning of the period and held for the entire period (February 1, 2019 to July 31, 2019).

Actual Expenses

The first line of the accompanying table provides information about actual account values and actual expenses. You may use the information in this line, together with the amount you invested, to estimate the expenses that you paid over the period. Simply divide your account value by $1,000.00 (for example, an $8,600 account value divided by $1,000.00 = 8.6), then multiply the result by the number in the first line under the heading entitled "Expenses Paid During Period" to estimate the expenses you paid on your account during this period. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Hypothetical Example for Comparison Purposes

The second line of the accompanying table provides information about hypothetical account values and hypothetical expenses based on the Fund's actual expense ratio and an assumed rate of return of 5% per year before expenses, which is not the Fund's actual return. The hypothetical account values and expenses may not be used to estimate the actual ending account balance or expenses you paid for the period. You may use this information to compare the ongoing costs of investing in the Fund and other funds. To do so, compare this 5% hypothetical example with the 5% hypothetical examples that appear in the shareholder reports of the other funds. In addition, the Fund, as a shareholder in the underlying Fidelity Central Funds, will indirectly bear its pro-rata share of the fees and expenses incurred by the underlying Fidelity Central Funds. These fees and expenses are not included in the Fund's annualized expense ratio used to calculate the expense estimate in the table below.

Please note that the expenses shown in the table are meant to highlight your ongoing costs only and do not reflect any transaction costs. Therefore, the second line of the table is useful in comparing ongoing costs only, and will not help you determine the relative total costs of owning different funds.

	Annualized Expense Ratio-A	Beginning Account Value February 1, 2019	Ending Account Value July 31, 2019	Expenses Paid During Period-B February 1, 2019 to July 31, 2019
Actual	.50%	$1,000.00	$993.30	$2.47-C
Hypothetical-D		$1,000.00	$1,022.32	$2.51-C

 ^A Annualized expense ratio reflects consolidated expenses net of applicable fee waivers.

 ^B Expenses are equal to the Fund's annualized expense ratio, multiplied by the average account value over the period, multiplied by 181/365 (to reflect the one-half year period).

 ^C If fees and changes to the Fund level expense contract and/ or expense cap effective August 1, 2019, had been in effect during the current period, the restated annualized expense ratio would have been .43% and the expenses paid in the actual and hypothetical examples above would have been $2.13 and $2.16, respectively.

 ^D 5% return per year before expenses

Distributions (Unaudited)

A total of 99.33% of the dividends distributed during the fiscal year was derived from interest on U.S. Government securities which is generally exempt from state income tax.

The fund will notify shareholders in January 2020 of amounts for use in preparing 2019 income tax returns.

The trust's Audit Committee has considered non-audit services that were not pre-approved that were provided by Deloitte Entities and PwC to Fund Service Providers to be compatible with maintaining the independence of Deloitte Entities and PwC in their

audits of the Funds, taking into account representations from Deloitte Entities and PwC, in accordance with Public Company Accounting Oversight Board rules, regarding their independence from the Funds and their related entities and Geode’s review of the appropriateness and permissibility under applicable law of such non-audit services prior to their provision to the Fund Service Providers.

Audit Committee Pre-Approval Policies and Procedures

The trust’s Audit Committee must pre-approve all audit and non-audit services provided by a fund’s independent registered public accounting firm relating to the operations or financial reporting of the fund. Prior to the commencement of any audit or non-audit services to a fund, the Audit Committee reviews the services to determine whether they are appropriate and permissible under applicable law.

The Audit Committee has adopted policies and procedures to, among other purposes, provide a framework for the Committee’s consideration of non-audit services by the audit firms that audit the Fidelity funds. The policies and procedures require that any non-audit service provided by a fund audit firm to a Fidelity fund and any non-audit service provided by a fund auditor to a Fund Service Provider that relates directly to the operations and financial reporting of a Fidelity fund (“Covered Service”) are subject to approval by the Audit Committee before such service is provided.

All Covered Services must be approved in advance of provision of the service either: (i) by formal resolution of the Audit Committee, or (ii) by oral or written approval of the service by the Chair of the Audit Committee (or if the Chair is unavailable, such other member of the Audit Committee as may be designated by the Chair to act in the Chair’s absence). The approval contemplated by (ii) above is permitted where the Treasurer determines that action on such an engagement is necessary before the next meeting of the Audit Committee.

Non-audit services provided by a fund audit firm to a Fund Service Provider that do not relate directly to the operations and financial reporting of a Fidelity fund are reported to the Audit Committee periodically.

Non-Audit Services Approved Pursuant to Rule 2-01(c)(7)(i)(C) and (ii) of Regulation S-X (“De Minimis Exception”)

There were no non-audit services approved or required to be approved by the Audit Committee pursuant to the De Minimis Exception during the Funds’ last two fiscal years relating to services provided to (i) the Funds or (ii) any Fund Service Provider that relate directly to the operations and financial reporting of the Funds.
