U.S. Treasury pulls back on controversial crypto mixer reporting rule
FinCEN has withdrawn its proposed rule that would have forced banks to flag cryptocurrency transactions involving mixers, after industry and privacy objections.
The U.S. Treasury’s Financial Crimes Enforcement Network announced the removal of a rule that would have compelled banks and other covered entities to report cryptocurrency transactions they believed involved mixers or similar privacy tools. First introduced in October 2023, the proposal faced pushback from the crypto sector and privacy advocates who argued the expansive definition of "mixing" could chill lawful activity and create a costly reporting load.
Industry groups such as the Blockchain Association and major exchange Coinbase warned the rule would drive illicit trades offshore and hamper cybersecurity practices. A July 2025 White House report echoed these concerns, noting that over-regulation could make American crypto firms less competitive. Although the rule has been withdrawn, FinCEN indicated it will continue to watch mixer activity for signs of money laundering or terrorist financing and may act in the future.
Why it matters
The rollback eases regulatory pressure on crypto firms while keeping government eyes on potential money-laundering tools.
