Japan's Bond Yield Breaks Three-Decade Barrier, Signals Shift to Domestic Assets

The benchmark Japanese bond yield has broken through a three-decade-old barrier of 3% for the first time since 1996. This significant threshold is not only crucial for funding costs in Tokyo but also marks a turning point in the investment flow that has made Japan the largest owner of U.S. Treasuries and one of the most reliable buyers of sovereign debt worldwide.

Global bond markets were shaken in July when Japan floated the possibility of a pivot by its Government Pension Investment Fund to domestic assets, but it's still unclear if this behemoth is adjusting its portfolio. Other Japanese institutional funds are reassessing opportunities at home, and a survey of 82 corporate Japanese pension funds showed that the net share planning to boost domestic bond holdings was the highest since 2008.

As JGB yields rise, the relative attractiveness of domestic bonds improves on a currency-hedged basis, potentially encouraging a shift from overseas assets back into Japanese fixed income. Japanese investors have already sold a net ¥3 trillion ($18.7 billion) in overseas debt through August 22, the biggest year-to-date outflow since bonds tanked in 2022.

According to Michael Weidner, co-head of global fixed income at Lazard Asset Management, 'they've underinvested in yen securities for probably 25 years. Now it's become more attractive and they are reallocating.'
