FinCEN released a proposed rule that would identify international convertible virtual currency mixing as a class of transactions of “primary money laundering concern” – a designation that would result in additional reporting and recordkeeping requirements for financial institutions for transactions involving CVC mixers.
On October 19, 2023, the Financial Crimes Enforcement Network (FinCEN) released a notice of proposed rulemaking (NPRM) that would designate transactions involving international convertible virtual currency[1] mixing (CVC mixing) as a class of transactions of primary money laundering concern.[2] Once implemented, the proposed rule would require covered financial institutions to collect and report certain details on transactions in CVC (including bitcoin and other digital assets) that the institutions know, suspect, or have reason to suspect involve CVC mixing activities outside of the United States. The NPRM is one of a series of measures that the United States Treasury Department (Treasury) has taken in recent years to target CVC mixers, which are third-party services used to anonymize cryptocurrency transactions.[3] According to Treasury, North Korea, terrorist groups, and other illicit actors have exploited CVC mixers to launder criminal proceeds and evade sanctions. FinCEN believes that the NPRM will curb the misuse of CVC mixers and facilitate law enforcement investigations into CVC transactions.
