Thailand plans overhaul of securities laws to enhance financial oversight

Thailand’s Cabinet on August 25 approved four amendment bills designed to reshape the country’s capital-market laws, granting its Securities and Exchange Commission new powers to investigate serious financial crimes and tightening oversight of auditors and financial advisers.

What the reforms actually change

The four bills amend several foundational statutes, including the Securities and Exchange Act B.E. 2535, which dates back to 1992, and the Emergency Decree on Digital Asset Businesses B.E. 2561 from 2018.

The SEC will gain expanded authority to expedite investigations into serious capital-market offenses. That means faster enforcement timelines and more direct supervision over gatekeepers like auditors and financial advisers.

The amendments also modernize rules around electronic documentation, making digital processes legally valid in contexts where paper used to be king. Secondary market regulations and fundraising processes both get updates as well.

One amendment specifically targets alignment of the Emergency Decree on Digital Asset Businesses, the legal backbone governing crypto exchanges, token offerings, and digital asset custodians operating in Thailand.

SEC Secretary-General Pornanong Budsaratragoon described the reforms as a necessary step toward boosting market transparency and competitiveness in the digital age.

The backstory

These bills didn’t materialize out of thin air. They followed public consultations conducted in June 2026 that addressed several pain points in Thailand’s markets, including undisclosed share pledges and disclosure requirements for major shareholders.

The consultations also explored short-sale practices. The proposals went through thorough reviews by the Office of the Council of State before landing on the Cabinet’s desk.

What this means for markets

The enhanced disclosure requirements for major shareholders could also change trading dynamics. When large holders are required to be more transparent about their positions and pledges, the information asymmetry between institutional and retail investors narrows.

For Thailand’s fintech sector, the reforms create a clearer runway. By consolidating various reform efforts into a single legislative package, the Cabinet is reducing the number of open questions that fintech founders and their lawyers have to navigate.

The bills still need to pass through Thailand’s legislative process, so the timeline for implementation remains an open question. But the Cabinet approval clears a significant hurdle, and the prior legal review by the Council of State suggests the government is confident in the bills’ viability.
