Two of Japan’s leading life insurance companies have reported large unrealised losses on their domestic government bond portfolios, highlighting the growing impact of rising interest rates on institutional investors.
A Bloomberg report has revealed that Meiji Yasuda Life Insurance’s paper losses on Japanese bond holdings surged to approximately ¥1.386 trillion (US$9.7 billion) in the fiscal year ended March 2025. This compares to ¥161.4 billion in the previous year, marking a substantial year-over-year increase.
Nippon Life Insurance, the country’s largest life insurer by assets, disclosed even greater unrealised losses of about ¥3.6 trillion (US$25 billion) over the same period. In addition, Nippon Life realised approximately ¥500 billion in losses through bond sales during the fiscal year.
The losses are primarily associated with long-duration Japanese government bonds, which have experienced significant price declines as domestic yields climb to multi-year highs, according to Bloomberg’s report.
As part of their response, both insurers have started reevaluating their investment strategies.
Nippon Life said it intends to limit its acquisition of government bonds in the current fiscal year, aiming to reduce exposure to interest rate risk on a book-value basis.
Meiji Yasuda has also signalled a reassessment of its investment allocations in light of ongoing market shifts.
A Nippon Life representative said the company would “moderate future bond purchases to maintain a more balanced investment position given prevailing interest rate conditions.”
Insurers traditionally favour long-term debt to match the maturity profiles of their policy obligations. However, the increased rate volatility and weakening bond prices have added complexity to asset-liability management.
The effect of rising rates is being felt across Japan’s broader financial landscape.
Norinchukin Bank has flagged caution around further investments in sovereign bonds, citing the growing risk from rate movements.
Similarly, Sony Life Insurance has indicated plans to divest some of its bond holdings to guard against further valuation declines.
These responses reflect a broader pivot among institutional investors, who are reconfiguring fixed-income exposures amid expectations of a prolonged higher-rate environment.
Separately, market sentiment saw a short-term uplift following a joint decision by the US and China to temporarily halt the escalation of tariffs.
The 90-day pause involves reductions in duties on bilateral trade, which led to gains in Asian equity indices and emerging market currencies.
This easing in trade tensions may offer near-term stability for insurers with exposure to global trade or investments linked to export-oriented sectors.
