South Korean insurers face new capital rule pressure

Fitch said overall buffers remain sufficient to absorb the changes.

South Korean insurers are likely to see more stable capital positions and profitability as rising interest rates reduce pressure on solvency and support investment returns.

Fitch Ratings said higher market interest rates are expected to moderate reductions in liability discount rates, helping ease near-term solvency pressures across the sector.

Whilst insurers may face some unrealised investment losses in the short term, higher rates should also improve investment yields over time.

Fitch expects the industry's capitalisation and profitability to stabilise, supported by stronger market rates and continued growth in in-force contractual service margin (CSM), a key measure of future profit under insurance accounting standards.

The agency noted that the Korean Insurance Capital Standard (K-ICS) ratio improved during 2025, indicating stronger capital adequacy across the sector. 

However, net income declined during the year before, partially recovering in the first quarter of 2026.

Fitch also highlighted upcoming regulatory changes that could place additional pressure on some insurers. 

These include the standardisation of actuarial assumptions and the introduction of a minimum core capital requirement.

The agency said the impact of the new rules will differ across insurers depending on their actuarial assumptions and underwriting practices. 

Despite the expected challenges, Fitch believes the sector's overall capital buffers remain sufficient to absorb the changes.
