On July 11, 2026, media reports conveyed key messages from Bank of Thailand (BOT) Governor Vitai Ratanakorn’s announcement of a sweeping regulatory crackdown on grey capital activities. The measures target high-value cash transactions, gold trading, and stablecoin flows, with new requirements set to take effect in the fourth quarter of 2026. The initiative aims to prevent financial institutions from facilitating shadow economy activity, money laundering—particularly through stablecoins—and capital flight, through enhanced compliance obligations on commercial banks across multiple transaction channels. Expanded Cash Controls Close the Deposit–Withdrawal Circuit New fourth-quarter guidelines will require individuals depositing THB 5 million or more in cash to formally verify the source of their funds.

That initial measure caused high-value physical cash withdrawals to drop by 35 percent nationwide. The upcoming deposit-side requirement closes the circuit on large cash movements. The BOT is also assessing tracking mechanisms for high-value banknote swaps, specifically targeting individuals seeking to exchange large volumes of THB 1,000 notes into smaller THB 100 or THB 500 denominations without clear business justification. Governor Vitai emphasized that these measures require continuous deployment of multiple parallel strategies rather than short-term fixes.

Gold shops are reminded of their duties to flag and report cash
