Japan’s leading life insurers are reportedly moving to swap low-yield domestic bonds for higher-return alternatives as they adjust to rising yields on Japanese government bonds (JGBs).
According to a recent Reuters report, ten unnamed major life insurers—collectively managing nearly ¥300 trillion ($2 trillion) as of March—revealed in interviews that they are rebalancing their yen bond portfolios. Larger insurers, in particular, are preparing for a reduction in their overall holdings during the second half of the fiscal year ending March 2026.
The shift follows a sharp increase in JGB yields, which began in late May after weak results in government debt auctions raised concerns about declining demand. The pressure on the JGB market has been exacerbated by reduced purchases from the Bank of Japan and fears of fiscal deterioration. In response, insurers are taking steps to mitigate the risk of losses and improve the quality of their portfolios by replacing older, lower-yield bonds.
In addition to shifting their bond strategies, many insurers are also focusing on reducing their domestic equity holdings, which had reached record valuations in recent months.
