International Spillovers on Government Bond Yields: Are We All in the Same Boat?
Should we expect the Federal Reserve’s large-scale asset purchases since late 2008 to have much impact on bond yields beyond U.S. borders? Prior studies (mostly of particular events, such as Neely ) say yes. They find evidence of cross-country spillovers in the international bond market, but provide little insight into the strength, scope, and dynamics of these spillover effects. In this post, we quantify the international transmission of financial shocks between the U.S. government bond market and three other developed countries, thus providing a benchmark measure of the cross-country spillover effects in the international bond market. We find that an unexpected increase of 1 percent in long-term U.S. bond yields can lead to a 0.14 percent to 0.19 percent rise in the bond yields of other developed countries on impact, and that the cumulative spillover effect from U.S. to foreign bond markets ranges from 0.26 percent to 0.35 percent over a longer horizon.
