Thailand's central bank (BOT) is coordinating with banks and non-bank financial institutions to combat grey capital, corruption, and money laundering. Implemented measures include requiring cash withdrawals above 5 million baht to disclose fund sources (reducing large cash transactions by 52%), and monitoring bulk gold purchases over 2 kg (down 70%). New compliance risks are emerging through FX trading, USDT tokens, and non-bank e-wallet services used by online gambling networks. BOT is expanding oversight into non-bank sectors to close these loopholes and prevent the financial system from enabling illegal activities.
