Portfolio Turnover [Heading]	rr_PortfolioTurnoverHeading	Portfolio Turnover
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 the fund’s 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. A portfolio turnover rate is not shown since the fund had not commenced operations during its most recent fiscal year.
Expense Example [Heading]	rr_ExpenseExampleHeading	Example
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 those periods, that your investment has a 5% return each year, and that the fund’s operating expenses remain the same. The example also assumes that an expense limitation currently in place is not renewed; therefore, the figures have been adjusted to reflect fee waivers or expense reimbursements only in the periods for which the expense limitation arrangement is expected to continue. Although your actual costs may be higher or lower, based on these assumptions your costs would be:
Strategy [Heading]	rr_StrategyHeading	Investments, Risks, and Performance Principal Investment Strategies
Strategy Narrative [Text Block]	rr_StrategyNarrativeTextBlock	Under normal conditions, the fund invests at least 80% of its net assets (including any borrowings for investment purposes) in non-U.S. dollar-denominated bonds. In addition, under normal market conditions the fund will maintain at least 80% of its net assets in U.S. dollar currency exposure. The fund normally purchases bonds issued in foreign currencies, which may include bonds issued in emerging markets currencies. However, forward currency exchange contracts are typically used to protect the fund’s non-U.S. dollar-denominated holdings from adverse currency movements by hedging the fund’s foreign currency exposure back to the U.S. dollar. While the fund normally maintains at least 80% U.S. dollar currency exposure, the fund’s overall foreign currency exposure within the remainder of the portfolio (through unhedged non-U.S. dollar-denominated holdings and currency derivatives) will vary based on the adviser’s outlook on the strength or weakness of the U.S. dollar compared to foreign currencies and the relative value of various foreign currencies to one another. The fund’s overall foreign currency exposure will generally increase during periods where the U.S. dollar is viewed as less attractive relative to foreign currencies. Currency derivatives will frequently be used to shift investment exposure from one currency into another for hedging purposes, but they may also be used to enhance returns by gaining long or short exposure to certain currencies expected to increase or decrease in value relative to other currencies. Forward currency exchange contracts and other currency derivatives, such as swaps, options and futures, may be used to help protect the fund’s holdings from unfavorable changes in currency exchange rates, and the fund has flexibility to purchase and sell currencies independently of whether the fund owns bonds in those currencies and to engage in currency hedging transactions. The fund may take a short position in a currency, which means that the fund could sell a currency in excess of its assets denominated in that currency or the fund might sell a currency even if it does not own any assets denominated in that currency. The fund invests primarily in bonds that are rated investment grade (i.e., BBB- or equivalent, or better), as determined by at least one major credit rating agency or, if unrated, deemed to be of comparable quality by T. Rowe Price. The fund may invest up to 25% of its total assets in bonds that have received a below investment-grade rating from an established credit rating agency (i.e., BB and lower, or an equivalent rating), also known as junk bonds, or, if unrated, deemed to be below investment-grade quality by T. Rowe Price. If a bond is split-rated (i.e., rated investment grade by one rating agency and below investment grade by another rating agency), the higher rating will be used for purposes of this requirement. Investments may include bonds that are in default or with the lowest rating. There is no limit on the fund’s investments in investment-grade bonds of emerging markets issuers. The fund may use credit default swaps to buy or sell credit protection on individual bond issuers or sectors of the bond markets. Credit default swaps may be used to replicate the exposure of a bond or portfolio of bonds and as a hedge against a default or other credit event involving one of the fund’s holdings. However, they may also be used to enhance returns by selling protection in situations where the adviser has a positive view on an issuer’s credit quality or by buying protection in situations where the adviser has a negative view on an issuer’s credit quality. If the fund buys protection, it effectively takes a short position, and if the fund sells protection, it effectively takes a long position, with respect to the creditworthiness of the issuer or sector. Investment decisions are based on fundamental market factors, such as yield and credit quality differences among bonds as well as supply and demand trends and currency values. The fund generally invests in securities where the combination of fixed-income returns and currency exchange rates appears attractive or, if the currency trend is unfavorable, where we believe the currency risk can be minimized through hedging. The fund sells holdings for a variety of reasons, such as to adjust the portfolio’s average maturity or credit quality, to shift assets into and out of higher-yielding securities, or to alter geographic or currency exposure. Although the fund expects to generally maintain an intermediate- to long-term weighted average maturity, there are no maturity restrictions on the overall portfolio or on individual securities purchased by the fund. Through the use of futures contracts and interest rate swaps, the fund may either extend or shorten the overall maturity of the fund and adjust its exposure with respect to particular countries or bond markets. A short position in a bond market means that the fund, for example, could sell interest rate futures with respect to bonds of a particular market and the value of the futures contract would exceed the value of the bonds held by the fund (or the fund could sell futures with respect to a particular bond market without owning any bonds in that market). The fund is “nondiversified,” meaning it may invest a greater portion of its assets in fewer issuers than is permissible for a “diversified” fund.
Risk [Heading]	rr_RiskHeading	Principal Risks
Risk Narrative [Text Block]	rr_RiskNarrativeTextBlock	As with any mutual fund, there is no guarantee that the fund will achieve its objective. The fund’s share price fluctuates, which means you could lose money by investing in the fund. The principal risks of investing in this fund are summarized as follows: Active management risks The investment adviser’s judgments about the attractiveness, value, or potential appreciation of the fund’s investments may prove to be incorrect. If the investments selected and strategies employed by the fund fail to produce the intended results, the fund could underperform in comparison to other funds with a similar benchmark or similar objectives and investment strategies. Fixed income markets risks Economic and other market developments can adversely affect fixed income securities markets. At times, participants in these markets may develop concerns about the ability of certain issuers of debt securities to make timely principal and interest payments, or they may develop concerns about the ability of financial institutions that make markets in certain debt securities to facilitate an orderly market. Those concerns could cause increased volatility and reduced liquidity in particular securities or in the overall fixed income markets and the related derivatives markets. A lack of liquidity or other adverse credit market conditions may hamper the fund’s ability to sell the debt securities in which it invests or to find and purchase suitable debt instruments. International investing risks Investing in the securities of non-U.S. issuers involves special risks not typically associated with investing in U.S. issuers. International securities tend to be more volatile and less liquid than investments in U.S. securities and may lose value because of adverse local, political, social, or economic developments overseas, or due to changes in the exchange rates between foreign currencies and the U.S. dollar. In addition, international investments are subject to settlement practices and regulatory and financial reporting standards that differ from those of the U.S. Emerging markets risks The risks of international investing are heightened for securities of issuers in emerging market countries. Emerging market countries tend to have economic structures that are less diverse and mature, and political systems that are less stable, than those of developed countries. In addition to all of the risks of investing in international developed markets, emerging markets are more susceptible to governmental interference, local taxes being imposed on international investments, restrictions on gaining access to sales proceeds, and less liquid and less efficient trading markets. Currency risks Because the fund generally invests in securities issued in foreign currencies, the fund could experience losses based solely on the weakness of foreign currencies versus the U.S. dollar and changes in the exchange rates between such currencies and the U.S. dollar. However, because the fund is required to hedge most of its non-U.S. dollar-denominated holdings back to the U.S. dollar, the fund could also experience losses due to the weakness of the U.S. dollar compared to the currency in which holdings are denominated. Hedging risks The fund’s attempts at hedging may not be successful and could cause the fund to lose money or fail to get the benefit of a gain on a hedged position. If expected changes to securities prices, interest rates, currency values and exchange rates are not accurately predicted, or if market conditions are not favorable for hedging foreign currency exposure back to the U.S. dollar, the fund could be in a worse position than if it had not entered into such transactions. Credit risks An issuer of a debt instrument could suffer an adverse change in financial condition that results in a payment default, rating downgrade, or inability to meet a financial obligation. The fund’s overall credit risk is increased to the extent the fund invests in emerging markets bonds or bonds rated below investment grade. Junk bond risks The risks of default are much greater for emerging market bonds and securities rated as below investment grade (“junk” bonds). The fund is exposed to greater credit risk than other bond funds because companies in emerging markets are usually not as strong financially and are more susceptible to economic downturns. Junk bonds should be considered speculative as they carry greater risks of default and erratic price swings due to real or perceived changes in the credit quality of the issuer. Interest rate risks Interest rates may increase, causing a decline in bond prices (bond prices and interest rates usually move in opposite directions). Generally, securities with longer maturities or durations, and funds with longer weighted average maturities or durations, carry greater interest rate risk. The fund may face a heightened level of interest rate risk due to historically low interest rates, and the potential effect of any government fiscal policy initiatives; for example, the U.S. Federal Reserve Board has ended its quantitative easing program and may continue to raise interest rates. Liquidity risks The fund may not be able to sell a holding in a timely manner at a desired price. Reduced liquidity in the bond markets can result from a number of events, such as limited trading activity, reductions in bond inventory, and rapid or unexpected changes in interest rates. Less liquid markets could lead to greater price volatility and limit the fund’s ability to sell a holding at a suitable price. Nondiversification risks As a nondiversified fund, the fund has the ability to invest a larger percentage of its assets in the securities of a smaller number of issuers than a diversified fund. As a result, poor performance by a single issuer could adversely affect fund performance more than if the fund were invested in a larger number of issuers. The fund’s share price can be expected to fluctuate more than that of a comparable diversified fund. Derivatives risks The fund uses forward currency exchange contracts, swaps, options, and futures, and it is therefore exposed to additional volatility in comparison to investing directly in bonds and other debt securities. These instruments can be illiquid and difficult to value, may involve leverage so that small changes produce disproportionate losses for the fund and, if not traded on an exchange, are subject to the risk that a counterparty to the transaction will fail to meet its obligations under the derivatives contract. The fund’s principal use of derivatives involves the risk that anticipated changes in currency values, currency exchange rates, interest rates, or the creditworthiness of an issuer will not be accurately predicted, which could significantly harm the fund’s performance, and the risk that regulatory developments could negatively affect the fund’s investments in such instruments. Changes in regulations could significantly impact the fund’s ability to invest in specific types of derivatives, which could limit the fund’s ability to employ certain strategies that use derivatives.
