Crypto AML Enforcement in 2022: The Year Regulators Got Serious

2022 was a watershed year for cryptocurrency AML enforcement. The collapse of several major crypto platforms - including the FTX implosion in November - combined with a series of significant enforcement actions against exchanges, mixers, and DeFi protocols, made clear that the era of regulatory forbearance for the crypto sector was over. Regulators across multiple agencies - FinCEN, OFAC, DOJ, and the SEC - coordinated on enforcement actions that sent an unambiguous message: the virtual currency sector is subject to the same legal standards as traditional finance.

OFAC's sanctioning of Tornado Cash in August 2022 was the most significant regulatory action of the year for the crypto sector. Tornado Cash is a decentralized cryptocurrency mixer - a protocol that obscures the origin of cryptocurrency transactions by pooling and redistributing funds. OFAC designated Tornado Cash as a Specially Designated National, effectively prohibiting U.S. persons from using the protocol. The action raised fundamental questions about whether decentralized protocols can be sanctioned and sparked significant legal debate.

The Tornado Cash action had immediate practical implications for crypto businesses. Exchanges and wallets that had processed transactions involving Tornado Cash faced potential OFAC exposure, and many moved quickly to block addresses associated with the protocol. The action also reinforced the importance of blockchain analytics tools - businesses that could identify Tornado Cash-linked transactions in their customer activity were better positioned to assess and manage their OFAC exposure.

The FTX collapse in November 2022 exposed compliance failures that went far beyond AML - the exchange's internal controls, customer fund segregation, and governance were all deeply deficient. But the AML implications were significant: FTX had processed billions of dollars in transactions with limited customer due diligence, and the collapse revealed that the exchange's compliance program was largely a facade. The FTX collapse reinforced the lesson that compliance programs must be genuine, not performative.

For crypto businesses navigating the 2022 enforcement environment, the practical lessons are clear: implement robust customer due diligence, build blockchain analytics capabilities into your transaction monitoring program, screen against OFAC's SDN list in real time, and treat your compliance program as a genuine operational priority rather than a regulatory checkbox. The enforcement environment is not going to become more permissive - the trajectory is clearly toward more oversight and more enforcement.
