Thailand's Securities and Exchange Commission (SEC) has overhauled its approach to related-party transactions (RPTs) by issuing new rules that simplify approval processes while expanding oversight. Capital Market Supervisory Board Notification No. TorJor. 46/2568 will replace the longstanding Notification No. TorJor. 21/2551, which has governed RPT compliance for over a decade.

The new regulation takes effect on July 1, 2026. Any RPT matters approved by a company's board of directors or approved for shareholders' approval before that date remain subject to Notification No. TorJor. 21/2551.

The new RPT rules will introduce significant changes that market participants should carefully consider.
