The Thailand Securities and Exchange Commission has opened a public consultation on proposed principles to revise annual fees for securities and derivatives business operators. The review would update fee-setting criteria to reflect current business conditions, the changing nature of licensed activities, the volume of transactions under SEC supervision, and supervisory costs and inflation, while aiming to avoid an undue burden on firms and reduce disparities across operators. The proposal has three main elements. It would increase annual fee rates for investment advisory businesses and introduce fee collection for derivatives dealer businesses at a minimum rate equivalent to THB 50,000. It would also change the fee calculation method for investment unit dealers and derivatives agents so fees better reflect actual transaction volume. In addition, it would raise the maximum annual fee rates for securities and derivatives businesses so fee collection is more aligned with supervisory costs and promotes greater equality and fairness among business operators. The SEC Board approved the review in principle at its June 2026 meeting. The public hearing runs until 12 July 2026.
