Thailand's SEC (ก.ล.ต.) has reduced average capital market case investigation time from 2.3–2.5 years to 1 year 5 months, targeting all cases under 2 years by early 2027. The regulator is pushing through law amendments to expand short-sell oversight to individual investors (not just brokers), introduce joint investigation powers for serious cases, and adjust trading rules: Uptick Rule will apply per-stock based on 10% price drops, HFT definitions will shift to behavioral criteria, and Tick Size adjustments will begin with stocks priced 10–25 baht. These changes aim to improve market surveillance efficiency while maintaining fair process.
