Form 59 reporting by insiders in Thailand
Section 59 and the people it covers
Thai insider holdings are disclosed under Section 59 of the Securities and Exchange Act B.E. 2535 (1992). Directors, executives and auditors of a listed company report their holdings of its securities, and every change, to the Securities and Exchange Commission (SEC Thailand) on Form 59, through the SEC's online R59 system.
SEC Notification Sor Jor. 6/2567, issued on 5 March 2024 and in force since 16 March 2024, sets the current rules and replaced Notification Sor Jor. 38/2561. Beyond directors, executives and auditors, it names plan preparers and plan administrators. The report also covers the filer's spouse or cohabiting partner, minor children, and certain juristic persons in which they hold more than 30% of the voting rights.
Trade by trade, or batched up to THB 3 million
The old notification required a report within 3 business days of each transaction (7 for a filer new to the system). Since March 2024 a filer may keep reporting each trade, or consolidate. A consolidated report falls due within 3 business days of whichever comes first: cumulative transactions reaching THB 3 million, or six months after the first transaction. A spouse or partner who holds a post in the same listed company counts as having filed once the director or executive has reported.
The notification fixes the transaction date as the day of purchase, sale or transfer. For newly issued shares it uses the date the capital increase is registered with the Ministry of Commerce. A breach of Section 59 carries a fine of up to THB 500,000, plus up to THB 10,000 per day while it continues.
Where to read the filings, and our Thai archive
The SEC keeps a public Form 59 list that you can search by issuer and by transaction or filing date. Each row gives the executive's name, the relationship of the holder, the type of security, the date, the quantity, the average price in baht and whether the deal was an acquisition or a disposal. The list shows filings received in the last 3 years.
Our Thai feed is per-trade: price times volume gives a baht amount, which we convert to euros to compare with other markets. We paused the connector in July 2026, after SEC Thailand rebuilt its Form 59 search, so the Thai hub holds filings collected up to then. Because one consolidated report can bundle six months of dealings, check the transaction date on each card before reading a filing as recent.
