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

On December 10, 2025, Vietnam’s National Assembly enacted Law No. 139/2025/QH15 amending the Law on Insurance Business. The amendment, effective from January 1, 2026, introduces various changes in an effort to lift restrictions and hurdles for insurance businesses. Key points that may impact the activities of stakeholders in Vietnam’s insurance market are highlighted below. Management Personnel Qualifications To broaden the talent pool while ensuring competency standards, the amended law opens up the positions of director or general director to more candidates. Previously, candidates were required to hold either (i) a university degree or higher in insurance or (ii) a university degree in another discipline and an insurance certificate issued by a qualified insurance training institution. Now, candidates holding a university degree or higher in economics, finance, banking, law, business administration, accounting, or auditing, with at least one insurance‑related module, are also accepted. These changes are expected to mitigate the ongoing challenges faced by insurers in recruiting suitably qualified candidates for key executive positions, while still maintaining appropriate professional standards. Fewer Registrations for Insurance Businesses As part of the legislature’s broader initiative to reduce administrative burdens across all business sectors, the amended Law on Insurance Business relaxes registration requirements for the insurance industry, notably: Insurance enterprises and foreign non‑life insurance branches are no longer required to register and obtain prior approval from the Ministry of Finance (MOF) for their methodologies and bases for calculating premiums for motor vehicle insurance products (excluding compulsory civil liability insurance for motor vehicle owners). Instead, insurance enterprises are now only required to notify the MOF before applying or amending these methodologies. While life insurers must continue to register with the MOF their principles for separating owners’ equity from insurance premium funds, non‑life insurance enterprises and foreign non‑life insurance branches are now only required to notify

Thailand’s Office of Insurance Commission (OIC) has opened a public hearing period on its amendments of notifications concerning the timeframe for an insurance company to submit its annual financial statements and financial and operating reports (called “XML reports”). The amended notifications also require insurance companies to submit some data sets from the quarterly capital maintenance reports and XML reports to the OIC in advance, before the full reports are submitted. Key changes in these amended notifications are summarized below. Financial Statements Audited annual financial statements will need to be submitted to the OIC within two months from the last day of each calendar year (i.e., by the end of February of the following year), instead of within four months as currently required. Capital Maintenance Reports While the deadline for submitting quarterly capital maintenance reports is still 45 days from the last day of the quarter, the OIC will now require life and non-life insurance companies to submit a set of data from the report in advance, within 21 days from the last day of each quarter. This data set includes the following information from the capital maintenance report: Form 1 – Calculation of Capital Adequacy Ratio (CAR) Form 2 – Calculation of Total Capital Available (TCA) Form 4 – Calculation of Capital for Insurance Risk (Table 4.1, 4.2, 4.4, and 4.5 for life insurance companies; Table 4.1 and 4.2 for non-life insurance companies) Financial and Operating Reports (XML Reports) Similar to the audited annual financial statement, the annual XML report will need to be submitted to the OIC within two months from the last day of each calendar year, instead of within the current four-month timeframe. For quarterly XML reports, which must still be submitted within 45 days from the last day of each quarter, there is a new
