            Publication ID: 2026 

            Title: Implementation of Special Measure Regarding Convertible Virtual Currency Mixing, as a Class of Transactions of Primary Money Laundering Concern  

            Abstract:

FinCEN intends to issue a final rule, pursuant to section 311 of the USA PATRIOT Act, requiring covered domestic financial institutions and domestic financial agencies to implement certain recordkeeping and reporting requirements relating to transactions involving convertible virtual currency (CVC) mixing within or involving jurisdictions outside of the United States. FinCEN proposed that the term "CVC mixing" means the facilitation of CVC transactions in a manner that obfuscates the source, destination, or amount involved in one or more transactions, regardless of the type of protocol or service used. This definition includes methods used to obfuscate transactions and an exception for the use of internal protocols or processes to execute transactions by banks, broker-dealers, or money services businesses, including virtual asset service providers that would otherwise constitute CVC mixing, provided that these financial institutions preserve records of the source and destination of CVC transactions when using such internal protocols and processes; and provide such records to regulators and law enforcement, where required by law.
