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.

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. The example also assumes that your investment has a 5% return each year, the fund’s operating expenses remain the same, and the expense limitation currently in place is not renewed. 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	The fund normally invests at least 80% of its net assets (including any borrowings for investment purposes) in bonds, and seeks to offer some protection against rising interest rates and provide a low correlation with the equity markets. The fund may invest in a variety of debt securities, including obligations issued by U.S. and foreign governments and their agencies, bonds issued by U.S. and foreign corporations, and mortgage- and asset-backed securities, as well as bank loans, which represent amounts borrowed by companies from banks and other lenders. The fund normally invests at least 40% of its net assets in foreign securities, including securities of emerging market issuers, which may be denominated in U.S. dollars or non-U.S. dollar currencies. For purposes of determining whether a fund holding is a foreign security, the fund uses the country assigned to a security by Bloomberg or another third-party data provider. While there is no maximum amount that the fund may invest in securities of foreign issuers, through its non-U.S. dollar denominated holdings and the use of derivatives, the fund normally limits its overall foreign currency exposure to 50% of its net assets. The fund focuses mainly on holdings that are rated investment grade (AAA, AA, A, BBB, or an equivalent rating) by a credit rating agency or, if unrated, deemed to be investment grade by T. Rowe Price. However, the fund may invest up to 30% in high yield bonds, also known as junk bonds, and other holdings that are rated below investment grade (BB and lower, or an equivalent rating) by a credit rating agency or, if unrated, deemed to be below investment grade by T. Rowe Price. If a security is split-rated (i.e., rated investment grade by at least one rating agency and below investment grade by another rating agency) at the time of purchase, the higher rating will be used for purposes of this limit. When deciding whether to adjust duration (which measures the fund’s price sensitivity to interest rate changes) or allocations among the various sectors and asset classes (such as high yield corporate bonds, mortgage- and asset-backed securities, international bonds and emerging market bonds, and bank loans), the portfolio manager weighs such factors as expected interest rate movements and currency valuations, the outlook for inflation and the economy, and the yield advantage that lower rated bonds may offer over investment-grade bonds. The fund may invest in holdings of any maturity and does not attempt to maintain any particular weighted average maturity. The maturities of the fund’s holdings generally reflect the portfolio manager’s outlook for interest rates. The fund’s investment approach allows the flexibility to invest across the global fixed income universe without constraints to particular benchmarks or asset classes in an effort to create a portfolio with low overall volatility and consistent income even in a rising interest rate environment. Although the fund has broad discretion in seeking investments that offer some downside risk protection while retaining the traditionally attractive characteristics of fixed income investments, it is expected that the fund will normally maintain a relatively concentrated portfolio. As a result, the fund is “nondiversified,” meaning it may invest a greater portion of its assets in fewer issuers than is permissible for a “diversified” fund. While most assets are typically invested in bonds and other debt instruments, the fund also uses interest rate futures, interest rate swaps, forward currency exchange contracts, and credit default swaps in keeping with the fund’s objectives. Interest rate futures and interest rate swaps are primarily used to manage the fund’s exposure to interest rate changes and limit overall volatility by adjusting the portfolio’s duration and extending or shortening the overall maturity of the fund. Forward currency exchange contracts are used to limit overall volatility by protecting the fund’s non-U.S. dollar-denominated holdings from adverse currency movements relative to the U.S. dollar. However, such instruments may also be used to reduce volatility or generate returns by gaining exposure to certain currencies expected to increase or decrease in value relative to other currencies. The fund may buy or sell credit default swaps involving a specific issuer or an index in order to adjust the fund’s overall credit quality, as well as to protect the value of certain portfolio holdings. The fund may sell holdings for a variety of reasons, such as to alter geographic or currency exposure, to adjust the portfolio’s average maturity, duration, or credit quality or to shift assets into and out of higher-yielding or lower-yielding securities.
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 risk The fund is subject to the risk that the investment adviser’s judgments about the attractiveness, value, or potential appreciation of the fund’s investments may prove to be incorrect. If the securities selected and strategies employed by the fund fail to produce the intended results, the fund could underperform other funds with similar objectives and investment strategies. Fixed income markets risk 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. Bank loan risk To the extent the fund invests in bank loans, it is exposed to additional risks beyond those normally associated with more traditional debt securities. The fund’s ability to receive payments in connection with the loan depends primarily on the financial condition of the borrower and whether or not a loan is secured by collateral, although there is no assurance that the collateral securing a loan will be sufficient to satisfy the loan obligation. In addition, bank loans often have contractual restrictions on resale, which can delay the sale and adversely impact the sale price. Interest rate risk This is the risk that a rise in interest rates will cause the price of a fixed rate debt security to fall. Generally, securities with longer maturities and funds with longer weighted average maturities carry greater interest rate risk. The fund may be subject to a greater risk of rising interest rates due to the current period of historically low rates and the effect of potential government fiscal policy initiatives and resulting market reaction to those initiatives. Prepayment risk and extension risk Prepayment risk is the risk that the principal on mortgage-backed securities, other asset-backed securities or any debt security with an embedded call option may be prepaid at any time, which could reduce yield and market value. The rate of prepayments tends to increase as interest rates fall, which could cause the average maturity of the portfolio to shorten. Extension risk may result from a rise in interest rates, which tends to make mortgage-backed securities, asset-backed securities, and other callable debt securities more volatile. Credit risk This is the risk that an issuer of a debt security could suffer an adverse change in financial condition that results in a payment default, security downgrade, or inability to meet a financial obligation. Junk bonds carry a higher risk of default and should be considered speculative. The fund’s exposure to credit risk is increased to the extent it invests in securities that are rated noninvestment grade. Liquidity risk This is the risk that 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 significant 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. Foreign investing risk Investing in the securities of non-U.S. issuers involves special risks not typically associated with investing in U.S. issuers. Foreign securities tend to be more volatile and less liquid than investments in U.S. securities and may lose value because of adverse political, social, or economic developments overseas, or due to changes in the exchange rates between foreign currencies and the U.S. dollar. In addition, foreign investments are subject to settlement practices and regulatory and financial reporting standards that differ from those of the U.S. Emerging markets risk The risks of foreign 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 foreign developed markets, emerging markets are more susceptible to governmental interference, local taxes being imposed on foreign investments, restrictions on gaining access to sales proceeds, and less liquid and less efficient trading markets. Currency risk Because the fund may invest in securities issued in foreign currencies, the fund is subject to the risk that it 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. Any attempts at currency hedging may not be successful and could cause the fund to lose money. Nondiversification risk 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 risk To the extent the fund uses forward currency exchange contracts, interest rate futures, interest rate swaps, and credit default swaps, it may be 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 interest rate movements, expected changes in currency values and currency exchange rates, or the creditworthiness of an issuer will not be accurately predicted, which could significantly harm the fund’s performance and impair the fund’s efforts to reduce its overall volatility.
