Overview

Why use international bonds

Bond markets around the world don’t always move in the same direction at the same time; international bonds can help reduce reliance on a single market and broaden the opportunity set within fixed income.

By providing exposure to bonds issued outside the United States, advisors can access different economies, central bank policies, and interest-rate environments that may not be available through domestic bonds alone. And, when paired with domestic bonds, they can support a more globally diversified approach to fixed income portfolio construction.


Fund lineup

Vanguard's international bond lineup

For decades, Vanguard has viewed international fixed income as an important component of a diversified portfolio.

Our international-focused funds provide broad exposure to global investment-grade bond markets and can serve as dedicated international bond allocations within client portfolios. Vanguard global bond funds follow a currency-hedged approach, helping to reduce the impact of currency volatility so returns more closely reflect the performance of the underlying bonds.

Through ETF and mutual fund options, advisors can access this broad global exposure at Vanguard’s low costs.

Advisors seeking additional global diversification may also consider Vanguard’s core active fixed income ETFs, including Core Bond ETF, Core-Plus Bond ETF, and Multi-Sector Income Bond ETF. These funds typically allocate 15% to 25% of assets to international bonds.

Strategy

How international bonds help manage risk

When portfolios depend only on U.S. bonds, they're exposed to several risks, such as:

  • Concentration risk—Reliant on only one market.
  • Interest-rate risk—Exposure to a single interest-rate environment.
  • Economic-cycle risk—Exposure to a single economic backdrop.

International bonds can help address these risks by providing access to markets shaped by different economic cycles, inflation trends, monetary policies, and yield environments.

How advisors mitigate currency risk through hedging

Currency movements can have a meaningful impact on international bond returns. A foreign bond may perform as expected in its local market, but changes in exchange rates can either increase or reduce the return a U.S. investor receives.

Hedging seeks to reduce the impact of exchange-rate fluctuations so that the investment experience is driven more by the underlying bonds and less by currency movements. Though primarily a risk management tool, hedging can also affect returns positively or negatively.

As Figure 1 illustrates, total returns from hedged international bonds have come from both the underlying bonds and the currency-hedging process.1 During periods when U.S. short-term interest rates were higher than those of many developed markets, hedging contributed positively to returns for U.S. investors. This helps explain why the total return potential of hedged international bonds may differ from headline bond yields alone.

Use cases

International bonds in portfolio construction

Use case no. 1: Diversify across global economic and policy environments

International bonds can help diversify fixed income allocations by providing exposure to different central bank policies, inflation regimes, interest-rate cycles, and sovereign issuers. Because countries don't all respond to economic conditions the same way, international bond markets may experience different outcomes than the U.S. bond market.

For advisors seeking to reduce reliance on a single economic and policy environment, international bonds can broaden exposure across global fixed income markets.

Use case no. 2: Reduce volatility with comparable returns through hedging

Currency-hedged strategies seek to reduce the impact of exchange-rate fluctuations, allowing the investment experience to be driven more by the underlying bonds and less by currency movements.

For advisors seeking international diversification without taking on significant currency risk, hedged international bond strategies can help maintain a more bond-like return profile while preserving access to global markets.

Use case no. 3: Seek additional sources of return from different interest-rate cycles

Central banks do not move together. Differences in inflation, growth, and monetary policy can create different bond market outcomes across countries and regions.

For advisors with portfolios concentrated in U.S. bonds, international bonds may provide exposure to return opportunities that emerge from markets experiencing different economic and interest-rate environments.

Frequently asked questions

Vanguard research suggests a modest allocation of around 30% to international bonds can help reduce portfolio volatility, with diversification benefits decreasing when the allocation is above that level.²

Hedged international bonds mitigate changes in exchange rates, keeping the returns focused on the bond itself rather than the currency. Additionally, during periods when U.S. short-term interest rates were higher than those of many developed markets, the currency-hedging process contributed to total returns positively (See Figure 1 for more information on currency hedging returns).

International bonds can diversify fixed income allocations beyond the United States and provide exposure to different economic and interest-rate environments while seeking to provide a level of return similar to that of a domestic-only portfolio.

International bonds can involve risks related to interest rates, credit, country or regional exposure, liquidity, and currencies. Currency-hedged strategies seek to reduce exchange-rate risk, but they do not eliminate all risks associated with investing outside the United States.

Vanguard international bond funds typically focus on providing broad exposure to investment-grade bond markets outside the United States which can help investors access a wider range of economies, interest-rate environments, and sources of diversification. The specific country and regional exposure will vary by fund and investment strategy.

Vanguard ETF Shares are not redeemable with the issuing Fund other than in very large aggregations worth millions of dollars. Instead, investors must buy and sell Vanguard ETF Shares in the secondary market and hold those shares in a brokerage account. In doing so, the investor may incur brokerage commissions and may pay more than net asset value when buying and receive less than net asset value when selling.

Bond funds are subject to the risk that an issuer will fail to make payments on time, and that bond prices will decline because of rising interest rates or negative perceptions of an issuer's ability to make payments.
