HyoBae Kim (pictured), head of business APAC at RNA Analytics, said South Korea’s insurance industry is navigating a period of significant change as it adapts to new regulatory frameworks, demographic shifts, and economic volatility.
The dual adoption of IFRS 17 and K-ICS has placed South Korean insurers in a unique position globally, requiring them to meet more rigorous compliance standards and overhaul their financial reporting systems.
These changes have introduced new operational and actuarial challenges, with some insurers encountering difficulties in accurately reporting under the new standards.
Even two years after implementation, the industry continues to work through the complexities of these frameworks, which have prompted a reassessment of capital management and risk strategies.
South Korea’s population is aging rapidly, with those aged 65 and above now accounting for more than 20% of the population as of December 2024. This demographic milestone classifies the country as a “super-aged society” and presents new challenges for life insurers.
The rising number of older policyholders, coupled with a declining birth rate, is shrinking the working-age population and reducing the premium base, while increasing claims exposure.
For actuaries, these trends require a review of mortality and longevity assumptions, as well as adjustments in pricing for annuities and pension products.
Insurers are also seeing increased demand for products tailored to seniors, such as whole-life and pension policies.
The need to address protection gaps and ensure affordability for older customers is becoming more pronounced, while stricter regulatory requirements for liability valuation and capital adequacy add further complexity to risk management.
The insurance sector’s short-term profitability is being tested by macroeconomic uncertainty. The Bank of Korea is considering additional interest rate cuts as the economy faces recession risks and ongoing global trade tensions.
Kim said these developments are affecting liability valuations under IFRS 17 and influencing investment returns and product profitability.
A June 2025 report from Fitch Ratings indicated that South Korean insurers recorded a modest increase in net profit in 2024, primarily due to investment performance, despite a decrease in insurance profits linked to regulatory changes.
Fitch expects that falling interest rates and tighter regulatory requirements could further pressure insurers’ capital positions.
In response, insurers are extending the duration of their liabilities, increasing investments in long-term fixed-income assets, and using derivatives to manage interest rate risk.
The average K-ICS ratio, including transitional measures, dropped to 197.9% in the first quarter of 2025, from 206.7% in 2024.
The regulatory benchmark for the K-ICS ratio was reduced from 150% to 130% in June 2025. Fitch noted that no further actuarial assumption changes are anticipated in the second half of the year, which may help stabilise insurers’ financial positions.
Kim said the convergence of regulatory, demographic, and economic pressures is increasing the importance of actuarial expertise in South Korea’s insurance sector.
Actuaries are being called upon to balance traditional risk assessment with new regulatory and market realities. Their work in adapting pricing, managing capital, and informing strategic decisions is expected to be central as insurers seek to maintain solvency and profitability in a rapidly evolving environment.
As the sector continues to change, the role of actuaries in navigating uncertainty and supporting long-term resilience remains critical for South Korean insurers.
