South Korean insurance companies will face new capital quality requirements starting in January 2027 that could reshape the sector’s financial landscape, according to a Fitch Ratings analysis.
The regulatory change introduces a minimum core capital ratio of 50%, designed to enhance insurer resilience by prioritizing higher-quality capital sources such as paid-in capital, retained earnings, and Tier 1 capital instruments. The new framework marks a significant shift from previous practices that allowed companies to boost solvency ratios through Tier 2 subordinated debt, Fitch noted.
“Proposed new core capital ratio requirements in South Korea will enhance the quality of insurers’ capital and sector resilience, but insurers could face challenges in optimizing capital structures depending on the costs of capital strengthening,” Fitch Ratings stated in the report.
The shift addresses vulnerabilities in the Korea Insurance Capital Standard solvency regime, which Fitch said had encouraged insurers to rely heavily on non-permanent subordinated securities. While this approach improved solvency ratios, it also increased refinancing risk and sector vulnerability during periods of stress.
Implementation challenges remain significant. As of the third quarter of 2025, 16 of 38 life and non-life insurance companies reported core capital ratios below 80%. The regulatory framework includes transitional measures spanning nine years through March 2036, giving insurers time to adjust their capital structures.
Fitch identified several obstacles insurers may encounter. Many Korean insurers lack the capacity to pay dividends required for Tier 1 capital instruments, limiting their options for strengthening core capital. In addition, companies that opt for early redemption of core capital securities must maintain an 80% core capital ratio, a threshold stricter than the 50% minimum requirement.
The new rules exclude contractual service margin (CSM) from core capital definitions, despite its recognition as capital under the solvency framework. “Fitch believes that it will take time for CSM to be fully recognized as core capital, since it must be gradually amortized as insurance services are provided,” the ratings agency said.
Insurers are expected to respond by reducing required capital through lower insurance and market risks, depending on their risk appetites and earnings stability. Fitch said sustained capital enhancement through stronger retained earnings, optimized liabilities, and prudent dividend policies will be essential to meeting the new requirements.
Regulatory intervention will target companies whose core capital ratios fall below the 50% minimum, with insurer-specific benchmarks based on each firm’s starting position.
