Premiums for savings-type insurance and short-payment whole life policies may rise by up to 10% next year after the Financial Supervisory Service set South Korea's 2027 average disclosed rate at 2.25%, down 0.25 percentage points from this year's 2.50% and the lowest level since 2023. The lagging benchmark reflects insurers' disclosed rates and expected asset-management returns. A lower rate reduces assumed investment returns used in premium calculations, potentially forcing insurers to charge more to provide the same benefits. Samsung Life Insurance and Hanwha Life Insurance cut savings-product disclosed rates despite higher market yields, leaving them below the Korea Insurance Development Institute's 2.40% October time-deposit estimate. The impact is expected to be greatest on savings-type and short-payment whole life policies, while auto insurance premiums face separate pressure from rising loss ratios. Life insurers' core insurance profit fell 26.2% year on year in the first half, new contracts declined 12.9% to 4,112,902 and surrender payments rose 39.2% to 28.97 trillion won in January-May.
