Thailand's central bank has intensified scrutiny on USDT transactions flagged as potential grey money movements. The monitoring initiative reflects growing concerns among regulators about how stablecoins facilitate large-value transfers that operate in regulatory grey zones. Bank of Thailand is tracking abnormal USDT trading patterns to identify potential money laundering risks and ensure compliance with anti-money laundering frameworks. This regulatory pressure on USDT echoes broader global trends where central banks and financial authorities are tightening oversight of stablecoin activities, particularly flows that bypass traditional banking channels. The move underscores the tension between crypto's borderless nature and governments' demand for financial surveillance—a dynamic that continues reshaping how institutional and retail players approach stablecoin usage.
