International reinsurers are expected to absorb over 93% of the proposed programme's THB75bn (US$2.27bn) exposure, with domestic carriers retaining only a small portion of the risk.
China Life, PICC, China Taiping, Sinosure, and China Re will take up to CNY70bn (US$10.4bn) of a CNY360bn recapitalisation that also covers three state banks.
The DFS review also called for stronger performance monitoring, wider digital adoption and improved customer grievance handling across the state-owned insurers.
The initial three-month agreement is expected to pave the way for a five-year partnership focused on improving insurance affordability and resilience, RACT said.
