Aflac Life Insurance's A+ Rating Reinforced by AM Best: Strategic Implications

On October 14, 2026, AM Best confirmed the Financial Strength Rating of A+ (Superior) and the Long-Term Issuer Credit Ratings of “aa” (Superior) for Aflac Life Insurance Japan, Ltd. and its U.S. entities, reinforcing Aflac Incorporated Group's stability and strength.

This affirmation of Aflac's ratings highlights the company's robust financial health and strategic competence in both the U.S. and Japan. Notably, AM Best acknowledged Aflac's superior risk-adjusted capitalization, cited through its Best’s Capital Adequacy Ratio (BCAR), emphasizing the firm's capacity to withstand economic fluctuations. Aflac's consistently strong operating performance is underpinned by its impressive solvency ratios in Japan and resilient risk-based capital in the United States.

Aflac's Financial Resilience and Strategic Moves

Aflac's financial resilience is further evidenced by its conservative financial leverage, ending at 22.2% in 2025, alongside substantial interest coverage. The insurer has fortified its liquidity through extensive cash reserves and Pre-Capitalized Securities Trust, which offers $2 billion in liquidity. Additionally, effective foreign exchange hedging and a diversified investment portfolio mitigate risks from commercial real estate delinquencies.

In operations, Aflac has maintained high profitability margins, with a return on equity exceeding 10% annually over the past five years and a return on revenue averaging 30.5%. Despite a slight rise in loss ratios due to a shifting U.S. business mix, its profit margins remain stable, thanks to ongoing client retention efforts and product enhancements.

Operational Strategies and Market Developments

Aflac's enterprise risk management (ERM) framework is integral to its operational strategy, aiding the company in navigating complex market dynamics while maintaining a competitive edge. This strategic integration is crucial, considering its leadership in medical and cancer insurance in Japan and prominence in the U.S. supplemental medical insurance market.

In a strategic expansion move, 2026 saw Aflac execute its first external reinsurance deal through Aflac Re Bermuda with Japan Post Insurance Company Ltd. This reinsurance agreement signifies Aflac’s intention to broaden its growth avenues and fortify its market position.

Acknowledged Credit Strength

AM Best's affirmation includes various long-term issue credit ratings (IRs), reflecting Aflac's consistent operational excellence and financial stability. These ratings encompass senior unsecured notes and subordinated debentures across a range of maturities and interest structures. Such affirmations not only validate Aflac’s creditworthiness but also reinforce investor confidence.
