Sumitomo Life Insurance said on October 26, 2026, that it would maintain its Japanese government bond investment pace in the second half of the fiscal year at the first-half level, while carefully monitoring super-long bond yields. The insurer expects its asset-liability management portfolio’s JGB holdings to decline despite the unchanged investment pace.
Key Takeaways
- The insurer plans to maintain its first-half JGB investment pace in the second half.
- Higher super-long yields offer better new-investment returns, but rapid moves could increase volatility.
- Sumitomo Life forecasts further Bank of Japan rate increases in December 2026 and April 2027.

Sumitomo Life balances higher yields against volatility
The insurer is keeping its investment pace steady rather than accelerating purchases in response to higher prospective returns. Tadakazu Izumi, general manager of its investment planning department, said rising super-long JGB yields improve returns on new investments and expand opportunities for life insurers.
Izumi also warned that rapid yield movements or a loss of market confidence in fiscal management could fuel volatility. The company’s stance therefore distinguishes the appeal of higher yields from the risks associated with how quickly they move.

Portfolio holdings are expected to keep declining
Sumitomo Life expects JGB holdings in its asset-liability management portfolio to decrease in the second half of the fiscal year, mirroring the first-half outcome. An unchanged investment pace does not necessarily mean an unchanged portfolio balance; the company did not provide a numerical target for the expected decline.
Its asset-liability management policy explains that investments are managed with the long-term characteristics of life insurance liabilities in mind. The stated approach seeks stable earnings while controlling risk, mainly through long-term interest-bearing assets such as public and corporate bonds and loans. That policy provides background to the portfolio’s purpose, rather than confirmation of the latest investment plans.
Rate and yield forecasts extend into spring 2027
The insurer expects the Bank of Japan to raise its policy rate to 1.5% in December 2026 and then to 1.75% in April 2027. It also forecasts higher benchmark government bond yields by the end of March 2027, as detailed below.
These figures are Sumitomo Life’s forecasts, not announced central-bank decisions or observed market yields. They set out the interest-rate environment the insurer anticipates while maintaining its investment pace.
Conclusion
The next test for Sumitomo Life’s outlook is whether yields develop as anticipated through the second half of the fiscal year. Its stated plan remains steady investment alongside a further decline in ALM portfolio JGB holdings.
