On October 19, the Financial Crimes Enforcement Network (FinCEN) declared that transactions involving foreign operating crypto-mixers, or services that obscure the original source and final destination of transactions on a public blockchain, are considered “Primary Money Laundering Concern”. This announcement has immediate implications for both U.S. financial institutions and the emerging field of decentralized finance (De-Fi). Paul Hastings LLP provided an in-depth analysis of the issue.
The announcement came with a notice of proposed rulemaking (NPRM) from FinCEN. This proposal advises U.S. financial institutions to report certain relevant information about mixer transactions involving a foreign jurisdiction to FinCEN. This move aims to enhance visibility into these transactions and potentially enable authorities to take action against suspicious activities more effectively.

Firstly, these new rules apply immediately to all U.S. financial institutions, making the reporting of transactions with potentially questionable blockchains compulsory. This requirement is not just for those transactions taking place within the United States but also those transactions that involve foreign jurisdictions.

Secondly, this determination directly implicates the burgeoning field of De-Fi. With an increase in the use of foreign operating crypto-mixers, this pronouncement places a larger burden on De-Fi platforms and protocols aiming to remain in legal compliance.
FinCEN’s decision marks a clear stepping stone in the attempt to bring a certain segment of cryptocurrency transactions into the purview of anti-money laundering (AML) regulations. The ripples this announcement could send through the legal, financial, and digital landscapes in the coming months and years are yet to be fully apprehended.
