Nippon Life outlook holds amidst equity and interest-rate risk exposure

The insurer’s securities portfolio keeps market sensitivity high even with a capital buffer in place.

Nippon Life Insurance Company is expected to remain resilient despite ongoing market volatility and interest rate uncertainty, according to AM Best.

The rating agency said the stable outlook reflects expectations that the insurer will be able to absorb market risks and maintain strong capital and earnings over the medium term.

AM Best said Nippon Life’s balance sheet is expected to stay at the strongest level, supported by risk-adjusted capitalisation under Best’s Capital Adequacy Ratio and a substantial capital base of $4.4t (¥8.7t) as of 31 March 2025.

Although absolute capital declined from $5.3t (¥10.5t) a year earlier due to lower unrealised gains on securities amidst weaker financial markets,

AM Best noted that capital has remained resilient, recovering to $5.0t (¥9.9t) by September 2025.

The agency also flagged the insurer’s continued exposure to equity and interest rate risks given its large securities portfolio, but said available capital provides a sufficient buffer.

It expects the October 2025 acquisition of Resolution Life Group Holdings to have a limited impact on balance sheet fundamentals, though some pressure on risk-adjusted capitalisation is anticipated due to the scale of the transaction.
