Thailand’s Office of Insurance Commission (OIC) has introduced comprehensive group-wide supervision requirements for insurers operating within corporate groups. Published on February 26, 2026, in two separate notifications in the Government Gazette, the new rules establish parallel frameworks for life and non-life insurance companies. Both notifications take effect on July 1, 2026, and impose significant new requirements on insurance business groups. Affected insurers should begin reviewing their group structures, governance frameworks, and risk management systems now to ensure timely compliance.
The notifications aim to ensure that group-level operations are orderly, stable, and reliable, and prevent the accumulation of systemic risk that could undermine public confidence in the insurance sector. Both notifications share a substantially parallel structure and require insurers to assess and manage the financial position, risk exposure, reliability, and corporate governance of their entire insurance business group on a comprehensive and ongoing basis.
The regulations introduce definitions for several key terms. An “insurance business group” encompasses the insurer together with its ultimate parent company, parent companies, subsidiaries, and related companies. The “head of the insurance business group” is the entity responsible for overseeing group-wide supervision, operations, and governance. An “ultimate parent company” is one that exercises control without itself being controlled by another entity.
Key Requirements
The notifications establish the following core obligations for insurers:
Group structure and shareholding reporting: Insurers must report the organizational chart and shareholding structure of their insurance business group—covering the ultimate parent company, parent companies, subsidiaries, and related entities—to the OIC registrar by June of each year, and whenever material changes occur. The regulations prescribe specific thresholds for determining when shareholding proportions constitute control.
Corporate governance standards: Board members, executives, and authorized persons of the ultimate parent company or parent company must not be disqualified (e.g., bankrupt individuals, persons convicted of property-related fraud, or persons removed from directorship for misconduct),
