The U.S. FinCEN links $12.7 billion in suspicious activities to Southeast Asian cryptocurrency investment scams

The Financial Crimes Enforcement Network (FinCEN) of the U.S. Department of the Treasury released an analysis and alert on Thursday, linking approximately $12.7 billion in suspicious financial activities to cryptocurrency investment scams operated by Southeast Asian parks. About 1,300 institutions submitted 33,904 suspicious activity reports covering the period from September 2023 to December 2025. Cryptocurrency-focused money service businesses submitted 55% of the reports, involving $5.5 billion; banks submitted 41%, involving $6.4 billion; and securities firms accounted for the remaining $784.5 million.

The number of reports has been growing at an average monthly rate of 10.9%, with the amount involved increasing by 18%. Scammers used at least 22 types of digital assets, with Ethereum, USDT, and USDC being the most common. On-chain analysis shows that regardless of the asset victims initially purchased, the funds are almost always converted into stablecoins, with nearly all converted to USDT, and then transferred through DeFi protocols or exchanges outside the U.S. Scammers also reused collection addresses across multiple victims, which is one way some institutions identified this pattern.

The report indicates that about 25% involved elderly individuals, which is comparable to the 24.4% of the population that is over 60 years old, leading FinCEN to conclude that the elderly are not disproportionately targeted. The FBI estimates that in 2024, the U.S. population over 60 lost $4.8 billion to scams. These parks are primarily located in Cambodia, Laos, and Myanmar, and U.S. authorities have seized over $25 million related to the associated scams this year.
