- Bank of Thailand is using data analytics to scan for abnormally high-volume stablecoin trades, particularly in Tether's USDT, flagging transactions that appear designed to evade disclosure rules or bypass normal banking channels, according to Governor Vitai Ratanakorn.
- Thailand's SEC, not the central bank, directly regulates digital assets; the Bank of Thailand is coordinating with the SEC, which holds authority to act on the stablecoin findings.
- Since April, banks must verify the purpose of cash withdrawals of 5 million baht (~$150,000) or more, a rule the central bank says cut large cash withdrawals by roughly 35%.
- From the fourth quarter, depositors bringing in 5 million baht or more in cash may have to declare where it came from.
- Tightened controls on high-value banknote exchanges and gold trading — where buyers were ordering gold via app and collecting same-day — helped cut monthly gold withdrawals from about 4,000 kilograms to around 700, with suspicious activity now reported to Thailand's Anti-Money Laundering Office.
- Banks have closed thousands of "mule" accounts linked to online gambling as part of the same grey-economy sweep.
- Thai police separately traced a romance-scam laundering network in which a single wallet moved more than $122.5 million in 10 months through cross-chain swaps, as part of Interpol's Operation First Light.
Why it matters: Thailand's grey-economy crackdown is producing measurable results — large cash withdrawals down roughly 35% and monthly gold withdrawals collapsing from ~4,000 kg to ~700 kg — but the stablecoin strand still needs Thailand's SEC to convert screening findings into enforcement, meaning USDT-heavy crypto firms face an imminent regulatory escalation in a market where agencies have already traced $122.5 million in laundering through a single wallet.
