These tables describe the fees and expenses that you may pay if you buy, hold and sell shares of the Fund. You may qualify for sales charge discounts in Class A if you and your family invest, or agree to invest in the future, at least $100,000 in Franklin Templeton funds. More information about these and other discounts is available from your financial professional and under “Your Account” on page 171 in the Fund's Prospectus and under “Buying and Selling Shares” on page 87 of the Fund’s Statement of Additional Information. In addition, more information about sales charge discounts and waivers for purchases of shares through specific financial intermediaries is set forth in Appendix A – "Intermediary Sales Charge Discounts and Waivers" to the Fund’s prospectus.

Please note that the tables and examples below do not reflect any transaction fees that may be charged by financial intermediaries, or commissions that a shareholder may be required to pay directly to its financial intermediary when buying or selling Class R6 or Advisor Class shares.

Portfolio Turnover [Text Block] rr_PortfolioTurnoverTextBlock

The Fund pays transaction costs, such as commissions, when it buys and sells securities (or "turns over" its portfolio). A higher portfolio turnover rate may indicate higher transaction costs and may result in higher taxes when Fund shares are held in a taxable account. These costs, which are not reflected in annual Fund operating expenses or in the Example, affect the Fund's performance. During the most recent fiscal year, the Fund's portfolio turnover rate was 23.94% of the average value of its portfolio.

Expense Example Narrative [Text Block] rr_ExpenseExampleNarrativeTextBlock

This Example is intended to help you compare the cost of investing in the Fund with the cost of investing in other mutual funds. The Example assumes that you invest $10,000 in the Fund for the time periods indicated and then redeem all of your shares at the end of the period. The Example also assumes that your investment has a 5% return each year and that the Fund's operating expenses remain the same. The Example reflects adjustments made to the Fund's operating expenses due to the fee waivers and/or expense reimbursements by management for the 1 Year numbers only. Although your actual costs may be higher or lower, based on these assumptions your costs would be:

Strategy [Heading] rr_StrategyHeading Principal Investment Strategies
Strategy Narrative [Text Block] rr_StrategyNarrativeTextBlock

Under normal market conditions, the Fund invests primarily in fixed and floating rate debt securities and debt obligations (including convertible bonds) of governments, government agencies and government-related or corporate issuers worldwide (collectively, “bonds”). Bonds may be denominated and issued in the local currency or in another currency. Bonds include debt securities of any maturity, such as bonds, notes, bills and debentures. The Fund may also invest in inflation indexed securities and securities or structured products that are linked to or derive their value from another security, asset or currency of any nation. In addition, the Fund's assets are invested in issuers located in at least three countries (including the U.S.). The Fund may invest without limit in developing markets.

The Fund is a "non-diversified" fund, which means it generally invests a greater portion of its assets in the securities of one or more issuers and invests overall in a smaller number of issuers than a diversified fund.

The Fund may buy bonds rated in any category, including securities in default. The Fund may invest in debt securities of any maturity, and the average maturity of debt securities in the Fund’s portfolio will fluctuate depending on the investment manager’s outlook on changing market, economic, and political conditions.

For purposes of pursuing its investment goals, the Fund regularly enters into various currency related transactions involving derivative instruments, principally currency and cross currency forwards, but it may also use currency and currency index futures contracts and currency options. The Fund maintains extensive positions in currency related derivative instruments as a hedging technique or to implement a currency investment strategy, which could expose a large amount of the Fund’s assets to obligations under these instruments. The results of such transactions may represent, from time to time, a large component of the Fund’s investment returns. The use of these derivative transactions may allow the Fund to obtain net long or net negative (short) exposure to selected currencies. The Fund may also enter into various other transactions involving derivatives, including interest rate/bond futures and swap agreements (which may include interest rate and credit default swaps). These derivative instruments may be used for hedging

purposes, to enhance returns, or to obtain net long or net negative (short) exposure to selected, interest rates, countries, durations or credit risks.

When choosing investments for the Fund, the investment manager allocates the Fund's assets based upon its assessment of changing market, political and economic conditions. It considers various factors, including evaluation of interest rates, currency exchange rate changes and credit risks. The investment manager may consider selling a security when it believes the security has become fully valued due to either its price appreciation or changes in the issuer's fundamentals, or when the investment manager believes another security is a more attractive investment opportunity.

The Fund may, at times, maintain a large position in cash and cash equivalents (including money market funds).

Risk [Heading] rr_RiskHeading Principal Risks
Risk Narrative [Text Block] rr_RiskNarrativeTextBlock

You could lose money by investing in the Fund. Mutual fund shares are not deposits or obligations of, or guaranteed or endorsed by, any bank, and are not insured by the Federal Deposit Insurance Corporation, the Federal Reserve Board, or any other agency of the U.S. government.

Foreign Securities (non-U.S.) Investing in foreign securities typically involves more risks than investing in U.S. securities, and includes risks associated with: (i) internal and external political and economic developments – e.g., the political, economic and social policies and structures of some foreign countries may be less stable and more volatile than those in the U.S. or some foreign countries may be subject to trading restrictions or economic sanctions; (ii) trading practices – e.g., government supervision and regulation of foreign securities and currency markets, trading systems and brokers may be less than in the U.S.; (iii) availability of information – e.g., foreign issuers may not be subject to the same disclosure, accounting and financial reporting standards and practices as U.S. issuers; (iv) limited markets – e.g., the securities of certain foreign issuers may be less liquid (harder to sell) and more volatile; and (v) currency exchange rate fluctuations and policies – e.g., fluctuations may negatively affect investments denominated in foreign currencies and any income received or expenses paid by the Fund in that foreign currency. The risks of foreign investments may be greater in developing or emerging market countries.

Currency Management Strategies   Currency management strategies may substantially change the Fund’s exposure to currency exchange rates and could result in losses to the Fund if currencies do not perform as the investment manager expects. In addition, currency management strategies, to the extent that they reduce the Fund’s exposure to currency risks, also reduce the Fund’s ability to benefit from favorable changes in currency exchange rates. Using currency

management strategies for purposes other than hedging further increases the Fund’s exposure to foreign investment losses. Currency markets generally are not as regulated as securities markets. In addition, currency rates may fluctuate significantly over short periods of time, and can reduce returns.

Sovereign Debt Securities   Sovereign debt securities are subject to various risks in addition to those relating to debt securities and foreign investments generally, including, but not limited to, the risk that a governmental entity may be unwilling or unable to pay interest and repay principal on its sovereign debt, or otherwise meet its obligations when due because of cash flow problems, insufficient foreign reserves, the relative size of the debt service burden to the economy as a whole, the government’s policy towards principal international lenders such as the International Monetary Fund, or the political considerations to which the government may be subject. If a sovereign debtor defaults (or threatens to default) on its sovereign debt obligations, the indebtedness may be restructured. Some sovereign debtors have in the past been able to restructure their debt payments without the approval of some or all debt holders or to declare moratoria on payments. In the event of a default on sovereign debt, the Fund may also have limited legal recourse against the defaulting government entity.

Regional   Adverse conditions in a certain region or country can adversely affect securities of issuers in other countries whose economies appear to be unrelated. To the extent that the Fund invests a significant portion of its assets in a specific geographic region or a particular country, the Fund will generally have more exposure to the specific regional or country economic risks. In the event of economic or political turmoil or a deterioration of diplomatic relations in a region or country where a substantial portion of the Fund’s assets are invested, the Fund may experience substantial illiquidity or reduction in the value of the Fund’s investments.

Developing Market Countries The Fund’s investments in securities of issuers in developing market countries are subject to all of the risks of foreign investing generally, and have additional heightened risks due to a lack of established legal, political, business and social frameworks to support securities markets, including: delays in settling portfolio securities transactions; currency and capital controls; greater sensitivity to interest rate changes; pervasiveness of corruption and crime; currency exchange rate volatility; and inflation, deflation or currency devaluation.

Market The market values of securities or other investments owned by the Fund will go up or down, sometimes rapidly or unpredictably. The market value of a security or other investment may be reduced by market activity or other results of supply and demand unrelated to the issuer. This is a basic risk associated with all investments. When there are more sellers than buyers, prices tend to fall. Likewise, when there are more buyers than sellers, prices tend to rise.

The current global outbreak of the novel strain of coronavirus, COVID-19, has resulted in market closures and dislocations, extreme volatility, liquidity constraints and increased trading costs. Efforts to contain the spread of COVID-19 have resulted in global travel restrictions and disruptions of healthcare systems, business operations and supply chains, layoffs, volatility in consumer demand for certain products, defaults and credit ratings downgrades, and other significant economic impacts. The effects of COVID-19 have impacted global economic activity across many industries and may heighten other pre-existing political, social and economic risks, locally or globally. The full impact of the COVID-19 pandemic is unpredictable and may adversely affect the Fund’s performance.

Liquidity From time to time, the trading market for a particular security or type of security or other investments in which the Fund invests may become less liquid or even illiquid. Reduced liquidity will have an adverse impact on the Fund’s ability to sell such securities or other investments when necessary to meet the Fund’s liquidity needs, which may arise or increase in response to a specific economic event or because the investment manager wishes to purchase particular investments or believes that a higher level of liquidity would be advantageous. Reduced liquidity will also generally lower the value of such securities or other investments. Market prices for such securities or other investments may be relatively volatile.

Interest Rate When interest rates rise, debt security prices generally fall. The opposite is also generally true: debt security prices rise when interest rates fall. Interest rate changes are influenced by a number of factors, including government policy, monetary policy, inflation expectations, perceptions of risk, and supply of and demand for bonds. In general, securities with longer maturities or durations are more sensitive to interest rate changes.

Credit An issuer of debt securities may fail to make interest payments or repay principal when due, in whole or in part. Changes in an issuer's financial strength or in a security's or government's credit rating may affect a security's value.

Derivative Instruments The performance of derivative instruments depends largely on the performance of an underlying currency, security, interest rate or index, and such derivatives often have risks similar to the underlying instrument, in addition to other risks. Derivatives involve costs and can create economic leverage in the Fund’s portfolio which may result in significant volatility and cause the Fund to participate in losses (as well as gains) in an amount that significantly exceeds the Fund’s initial investment. Other risks include illiquidity, mispricing or improper valuation of the derivative, and imperfect correlation between the value of the derivative and the underlying instrument so that the Fund may not realize the intended benefits. Their successful use will usually depend on the investment manager’s ability to accurately forecast movements in the market relating to the underlying instrument. Should a market or markets, or prices of particular classes

of investments move in an unexpected manner, especially in unusual or extreme market conditions, the Fund may not realize the anticipated benefits of the transaction, and it may realize losses, which could be significant. If the investment manager is not successful in using such derivative instruments, the Fund’s performance may be worse than if the investment manager did not use such derivatives at all. When a derivative is used for hedging, the change in value of the derivative may also not correlate specifically with the currency, security, interest rate, index or other risk being hedged. Derivatives also may present the risk that the other party to the transaction will fail to perform. There is also the risk, especially under extreme market conditions, that a derivative, which usually would operate as a hedge, provides no hedging benefits at all.

High-Yield Debt Securities Issuers of lower-rated or “high-yield” debt securities (also known as “junk bonds”) are not as strong financially as those issuing higher credit quality debt securities. High-yield debt securities are generally considered predominantly speculative by the applicable rating agencies as their issuers are more likely to encounter financial difficulties because they may be more highly leveraged, or because of other considerations. In addition, high yield debt securities generally are more vulnerable to changes in the relevant economy, such as a recession or a sustained period of rising interest rates, that could affect their ability to make interest and principal payments when due. The prices of high-yield debt securities generally fluctuate more than those of higher credit quality. High-yield debt securities are generally more illiquid (harder to sell) and harder to value.

Income The Fund's distributions to shareholders may decline when prevailing interest rates fall, when the Fund experiences defaults on debt securities it holds or when the Fund realizes a loss upon the sale of a debt security.

Non-Diversification Because the Fund is non-diversified, it may be more sensitive to economic, business, political or other changes affecting individual issuers or investments than a diversified fund, which may negatively impact the Fund's performance and result in greater fluctuation in the value of the Fund’s shares.

Cash Position To the extent that the Fund holds a large position in cash/cash equivalents (including money market funds) the Fund may lose opportunities to participate in market appreciation and may have lower returns than if the Fund made other investments. In such circumstances, the Fund may not achieve its investment goal.

LIBOR Transition The Fund invests in financial instruments that may have floating or variable rate calculations for payment obligations or financing terms based on the London Interbank Offered Rate (LIBOR), which is the benchmark interest rate at which major global banks lend to one another in the international interbank market for short-term loans. It was originally anticipated that LIBOR would be discontinued by the end of 2021 and would cease to be published after that time.

Although many LIBOR rates were phased out at the end of 2021 as originally intended, a selection of widely used USD LIBOR rates will continue to be published until June 2023 in order to assist with the transition to an alternative rate. The impact of the discontinuation of LIBOR and the transition to an alternative rate on the Fund's portfolio remains uncertain. There can be no guarantee that financial instruments that transition to an alternative reference rate will retain the same value or liquidity as they would otherwise have had.

Management The Fund is subject to management risk because it is an actively managed investment portfolio. The Fund's investment manager applies investment techniques and risk analyses in making investment decisions for the Fund, but there can be no guarantee that these decisions will produce the desired results.

Cybersecurity Cybersecurity incidents, both intentional and unintentional, may allow an unauthorized party to gain access to Fund assets, Fund or customer data (including private shareholder information), or proprietary information, cause the Fund, the investment manager sub-advisor and/or their service providers (including, but not limited to, Fund accountants, custodians, sub-custodians, transfer agents and financial intermediaries) to suffer data breaches, data corruption or loss of operational functionality or prevent Fund investors from purchasing, redeeming or exchanging shares or receiving distributions. The investment manager sub-advisor has limited ability to prevent or mitigate cybersecurity incidents affecting third party service providers, and such third party service providers may have limited indemnification obligations to the Fund and or sub-advisor. Cybersecurity incidents may result in financial losses to the Fund and its shareholders, and substantial costs may be incurred in order to prevent any future cybersecurity incidents. Issuers of securities in which the Fund invests are also subject to cybersecurity risks, and the value of these securities could decline if the issuers experience cybersecurity incidents.

Because technology is frequently changing, new ways to carry out cyber attacks are always developing. Therefore, there is a chance that some risks have not been identified or prepared for, or that an attack may not be detected, which puts limitations on the fund's ability to plan for or respond to a cyber attack. Like other funds and business enterprises, the fund, the investment manager sub-advisor and their service providers are subject to the risk of cyber incidents occurring from time to time.

The figures in the average annual total returns table above reflect the Class A shares maximum front-end sales charge of 3.75%. Prior to March 1, 2019, Class A shares were subject to a maximum front-end sales charge of 4.25%. If the prior maximum front-end sales charge of 4.25% was reflected, performance for Class A shares in the average annual total returns table would be lower.

The after-tax returns are calculated using the historical highest individual federal marginal income tax rates and do not reflect the impact of state and local taxes. Actual after-tax returns depend on an investor's tax situation and may differ from those shown. After-tax returns are not relevant to investors who hold their Fund shares through tax-deferred arrangements, such as 401(k) plans or individual retirement accounts. After-tax returns are shown only for Class A and after-tax returns for other classes will vary.

There is a 1% contingent deferred sales charge that applies to investments of $500,000 or more (see "Investment of $500,000 or More" under "Choosing a Share Class") and purchases by certain retirement plans without an initial sales charge on shares sold within 18 months of purchase.
[2] Total annual Fund operating expenses differ from the ratio of expenses to average net assets shown in the Financial Highlights, which reflect the operating expenses of the Fund and do not include acquired fund fees and expenses.
[3] The transfer agent has contractually agreed to cap transfer agency fees for Class R6 shares of the Fund so that the transfer agency fees for that class do not exceed 0.03% until April 30, 2023. During the term, this fee waiver and expense reimbursement agreement may not be terminated or amended without approval of the board of trustees except to add series and classes, to reflect the extension of termination dates or to lower the cap on Fund’s fees and expenses (which would result in lower fees for shareholders).
