Japanese government bond (JGB) yields have been on a significant upward trend, with the 10-year JGB yield hitting 3% for the first time since 1996, more than tripling over the past two years. This surge in domestic returns is making Japanese bonds more attractive, particularly on a currency-hedged basis, and is encouraging Japanese investors to repatriate capital that was previously invested in overseas debt.
This shift is evident in recent data, with Japanese investors selling a net 3 trillion yen ($18.7 billion) in overseas debt through August 22, marking the largest year-to-date outflow since 2022. A survey by J.P. Morgan Asset Management revealed that corporate Japanese pension funds are planning to boost domestic bond holdings at the highest rate since 2008, while simultaneously reducing their overseas debt holdings due to high currency hedging costs. Fund managers like Toshinobu Chiba of Simplex Asset Management have actively gone bearish on U.S. Treasuries to buy 10-year JGBs, calling it a "natural movement for Japanese investors."
The implications for global markets are significant. As JGB yields rise, the demand for U.S. Treasuries and other international bonds from Japanese investors, traditionally major buyers, is decreasing. Masahiko Loo, senior fixed income strategist at State Street Investment Management, noted that while it's not a "large-scale repatriation," Japan is "gradually ceasing to be the marginal buyer of foreign bonds." This reduction in incremental demand from one of the world's largest pools of savings is contributing to higher term premiums globally. The narrowing gap between 10-year JGB yields and 10-year U.S. Treasury yields, which has shrunk by over 100 basis points, further underscores this change.
Driving these rising JGB yields are several factors, including investors bracing for higher returns bloomberg.com, Prime Minister Sanae Takaichi's push for significant fiscal spending bnnbloomberg.ca, and expectations of a potential interest rate hike from the Bank of Japan later this month reuters.com. This has also led to a sudden surge in the yen, which had hit 40-year lows in July, and is causing an unwinding of the popular carry trade as investors anticipate further monetary tightening by the BOJ.
