U.S. Interest Rates: The Potential Shock Heard Around the World

By Serkan Arslanalp and Yingyuan Chen

As the financial market turbulence of May 2013 demonstrated, the timing and management of the U.S. Fed exit from unconventional monetary policy is critical. Our analysis in the latest Global Financial Stability Report  suggests that if the U.S. exit is bumpy (Figure 1), although this is a tail risk and not our prediction, the result could lead to a faster rise in U.S long-term Treasury rates that impacts other bond markets. This could have implications not only for emerging markets, as widely discussed, but, also for other advanced economies.

Indeed, historical episodes show that sharp rises in US treasury rates lead to increases in government bond yields across other major advanced economies.

Some facts 

During the last five episodes when 10-year U.S. Treasury rates rose rapidly, bond yields rose, on average, by 73 basis point in Canada, 66 basis points in the United Kingdom, 60 basis points in Germany, and 36 basis points Japan, for every 100 basis point rise in the U.S. Treasury rate (Figure 2).

We saw a similar effect when we looked at U.S. Treasury rates’ impact on emerging market local-currency bond yields, especially during the selloff in 2013.

Tracking the connection: the term premium is a key channel

Why are long-long term bond yields in advanced economies correlated with U.S. Treasury rates, especially during financial shocks? Why does the correlation vary by country?

To answer these questions, we separated bond yields into two components: expected short rates, which expectations of central bank policy rates determine, and the term premium— the compensation sought by investors for potential losses due to interest rate or inflation risk.

Our analysis showed that the term premium plays a key role in the transmission of U.S. shocks to other countries. We found that even if expected short rates deviated among countries because of differences in country circumstances, the term premium across countries was highly correlated.

Moreover, as with yields, we found the transmission of U.S. term premium shocks to other countries to be the highest for Canada, followed by the United Kingdom, Germany, and Japan.  Here’s why.

Closer: for better or for worse

There are two possible explanations for this correlation in term premia.

  • Financial linkages. There may be a “global price of risk” that leads investors to price term premium across advanced economy bond markets similarly through arbitrage, especially among countries with stronger financial linkages. Indeed, bond markets of major advanced economies have become increasingly integrated over time.
  • Economic linkages. Several studies, such as this one and this one, have shown that the term premium charged by investors tends to fluctuate with the country’s business cycle: when the economy is doing well, the premium drops, and vice versa.  And when the U.S. economy does well, other countries with close economic ties to the U.S. also do well. In effect, this synchronization of the business cycle across economies may be driving correlations in term premium.

These two factors could explain why we find a higher correlation of term premium between countries with stronger financial and economic linkages, such as Canada and the United States.

Implications for other countries

  • First, a bumpy U.S. exit from its unconventional monetary policy could have an impact on other countries through bond markets, if investors demand higher term premia in the United States.
  • Second, even if central banks outside the United States can fully control expected short-term rates through forward guidance, a rise in the U.S. term premium could still put upward pressure on long-term bond yields in other economies, including major advanced economies (Figure 3).

  • Third, for countries with highly leveraged balance sheets, the rise in long-term yields could put further pressure on the capacity to service debt and could create headwinds for growth.

These highlight the importance of achieving a smooth exit from unconventional monetary policy in the United States. For more on these and related issues, we encourage you to take a look at the current issue of the GFSR, which discusses factors that could complicate achieving a smooth exit, and implications of a potentially bumpy exit on emerging market economies in more detail.

    It would be quite interesting if you could provide more indications of how large the moves were for each country outside the US.
    For example:
    – z-score compared with historical rates volatility in each region
    – change in value for a standard 10-y maturity bond, or providing more details about the duration of the bonds you include in your review

    The results you provide are already very useful. Thanks for this insightful analysis.

    Thank you very much for your interest in our blog. We see a similar pattern in terms of z-scores—the impact of the shock during the May 2013 selloff episode was 3.7 times historical volatility for Canada, 2.3 times for the U.K. and Germany, and 1.8 times for Japan. Moreover, as you rightly point out, the duration of government bonds outstanding was much higher going into the latest sell-off episode, generating larges losses for bond investors all else equal. More specifically, the duration of the 10-year government bond was about 9 years Canada, Germany, and Japan, and 8½ years for the U.K., just before the May 2013 selloff episode.
