On September 23, 2026, the Trade Competition Commission of Thailand (TCCT) launched a one-month public consultation period on a proposed notification that would overhaul how antitrust offenses under the Trade Competition Act B.E. 2560 (2017) are settled and penalized. The draft notification would replace the existing 2019 settlement framework with more detailed procedures, introduce offense-specific methods for fine calculation, and add tiered deterrence multipliers. Comments may be submitted until October 22, 2026.

If the accused confesses, consents to settlement, and pays the fine within the prescribed period, the criminal case would be closed and the settlement recorded. Refusals would also be recorded for further arrangements, and failure to appear, pay, or consent would result in the TCCT forwarding the case file and its recommendation—along with the accused’s fingerprints—to the public prosecutor. Notably, the draft allows accused parties to request settlement even after the TCCT has recommended prosecution but before the public prosecutor files charges, subject to prosecutorial consent.

Fine Calculation Frameworks The proposed notification establishes different fine calculation approaches depending on the type of Trade Competition Act violation. For the most serious offenses (such as abusing market dominance, making anticompetitive agreements, or forming hardcore cartels) the
