Thailand just made it a lot harder to move large amounts of Tether without someone asking questions. The country’s central bank and securities regulator are jointly auditing high-volume USDT transactions, looking specifically for deals designed to hide ownership or dodge standard remittance channels.

Bank of Thailand Governor Vitai Ratanakorn announced the measures on July 11, 2026, signaling that enforcement will ramp up significantly in Q4 2026. The investigation has already referred findings for potential disciplinary actions to the SEC.

What the new rules actually look like

The joint audits, which kicked off in Q3 2026, sit alongside a fresh set of cash deposit regulations. Any cash deposit exceeding 5 million baht, roughly $140K at current exchange rates, now requires proof of the funds’ source.

This isn’t Thailand’s first move in this direction. Measures introduced in April 2026 already produced a 35% reduction in high-value cash withdrawals.
