The Thailand Office of Insurance Commission (OIC) has developed enhanced preventive supervision measures to strengthen insurers’ financial condition and stability, and met with the Thai Life Assurance Association and the Thai General Insurance Association on 21 April 2025 to explain the approach, gather feedback, and prepare the sector for implementation. The measures are intended to close gaps where existing legal intervention tools cannot be applied quickly because statutory conditions are not yet met, and to move beyond short-term remediation that relies mainly on capital increases. Designed as a legal tool within the registrar and officials’ powers, the framework would apply to insurers classified in groups 2, 3 and 4 under the Early Warning System, where indicators suggest potential impacts on financial position and stability, and would be applied before capital falls below the required level under Section 27 of the Life Insurance Act or Non-life Insurance Act. Intervention actions would be calibrated to the severity and root causes of problems, supported by clearer decision-making lines, and would use indicators reflecting current financial condition and the resilience of surplus to consecutive net losses, with escalation through three levels if issues are not addressed. The associations supported the approach while suggesting refinements, including whether loss assessments for life insurers should be considered differently from non-life insurers. The OIC will consider the feedback before enforcement and plans to communicate the finalised measures to all insurers.
