Japan's rising bond yields lure capital home, impacting global markets

Key facts

• Japanese benchmark bond yields have broken through a 30-year barrier, reaching 3%.
• This rise in yields is attracting Japanese capital back to domestic assets.
• Japanese investors have sold a net 3 trillion yen in overseas debt year-to-date through August 22.
• The narrowing yield gap between Japanese and global bonds, particularly US Treasuries, is a key driver.
• Institutional funds, including corporate pension funds, are increasing their allocation to domestic bonds.

Japanese benchmark bond yields have surpassed a significant 30-year barrier, reaching 3%, which is beginning to reverse long-standing global capital flows. This development is prompting Japanese investors to reallocate funds back into domestic assets, impacting markets that have relied on Japanese demand for sovereign debt, including US Treasuries.

Global fund managers and dealers have observed a noticeable pullback in Japanese demand for overseas bonds. Official data indicates that Japanese investors have sold a net 3 trillion yen (approximately $18.7 billion) in foreign debt year-to-date through August 22, marking the largest outflow since bonds experienced a significant downturn in 2022. This trend is driven by the increasing attractiveness of domestic yields, which have narrowed the gap with international counterparts.

Market participants in regions like Australia, where Japanese investors were once major foreign debt holders, are feeling this shift. Instead of accumulating new debt, Japanese investors are now more focused on holding existing exposures, indicating a "home market bias" for the first time in many years. This return-driven decision is influenced by the improved relative value of Japanese securities, especially on a currency-hedged basis.

Institutional investors are also reassessing their portfolios. A survey of 82 Japanese corporate pension funds revealed the highest net share planning to boost domestic bond holdings since the poll's inception in 2008. These funds are reducing overseas debt holdings, partly due to high currency hedging costs. The rise in Japanese Government Bond (JGB) yields, which have more than tripled over the past two years to hit 3% for the 10-year note for the first time since 1996, makes domestic fixed income more appealing.
