FinCEN announced it is withdrawing its 2023 finding on international crypto mixing and a proposed reporting rule that would have covered transactions involving mixing at financial institutions. The agency cited concerns that the broad definition could chill legitimate activity and impose substantial reporting burdens. The withdrawal is scheduled to take effect upon Federal Register publication on Oct. 6.
Why it matters
The proposal was not limited to dedicated mixing services. Its definition covered a range of activity, including pooling funds, coordinating transactions with code, splitting transfers, routing funds through single-use wallets, exchanging between crypto assets and adding user-initiated delays. Covered institutions would have reported information that could include wallet addresses, transaction hashes, IP addresses and customer identity details.
For users, the rollback removes this proposed reporting layer, but it does not eliminate existing anti-money-laundering requirements. FinCEN says covered crypto money transmitters remain subject to registration, risk-based AML programs, applicable customer checks, recordkeeping and suspicious activity reporting. Qualifying transfers also remain subject to the Funds Travel Rule.
Market impact
The decision narrows a proposed expansion of financial surveillance around crypto mixing and is a meaningful win for financial privacy advocates. FinCEN says it will continue monitoring mixing for money laundering, terrorist financing and other illicit activity, and may take further steps.
The agency’s guidance continues to distinguish operating a money-transmission business from merely supplying anonymizing software. Using an unhosted wallet to pay for goods or services on one’s own behalf does not, by itself, make the user a money transmitter. The withdrawal therefore changes the status of the proposed reporting rule, not the broader compliance framework for crypto transactions.
