The Securities and Exchange Commission, Thailand has issued rules requiring securities and derivatives business operators that hold clients’ investment portfolio data to prepare investment portfolio status reports and disclose or deliver them to clients, to support continuous performance tracking and long-term financial planning. The framework requires portfolio data to be maintained in a machine-readable format usable by automated tools, with reports including at least the list and quantity of securities or derivatives contracts, other client assets, average cost, and profit or loss. Clients must have real-time access via electronic channels such as mobile applications, websites, or data wallets; where this is not feasible, month-end reports must be delivered through an agreed channel (for example email or post) within the fifth business day of the following month, except when the client has no transactions during that month. The rules do not apply to securities business operators providing trading services for unit link. The requirements take effect from 16 July 2026.
