FinCEN and OFAC issue joint proposed AML/sanctions compliance rules for stablecoin issuers

On April 10, 2026, the Financial Crimes Enforcement Network (FinCEN) and Office of Foreign Assets Control (OFAC) jointly proposed rules formally classifying stablecoin issuers as financial institutions under the Bank Secrecy Act, following passage of the GENIUS Act. The proposed regulations require issuers to implement comprehensive AML/CFT programs including customer due diligence, suspicious activity reporting, and technical capabilities to block, freeze, or reject illicit on-chain transactions in both primary and secondary markets. Issuers must build kill switches directly into token infrastructure and deploy advanced blockchain analytics, with executives facing potential criminal liability for false compliance certifications. While Circle welcomed the regulatory clarity, the rules significantly raise operational costs and compliance burdens, though White House crypto adviser Patrick Witt argues the framework could attract net new capital into the US banking system while Treasury seeks to balance illicit finance prevention with maintaining American leadership in financial innovation.
