On April 8, 2026, the US Department of the Treasury’s Financial Crimes Enforcement Network (“FinCEN”) and Office of Foreign Assets Control (“OFAC”) issued a joint Notice of Proposed Rulemaking (the “Proposed Rule”) to implement the anti-money laundering (“AML”) and sanctions compliance provisions of the Guiding and Establishing National Innovation for US Stablecoins Act (the “GENIUS Act”) for permitted payment stablecoin issuers (“PPSIs”).

The Proposed Rule would treat PPSIs as “financial institutions” under the Bank Secrecy Act (“BSA”), require PPSIs to establish and maintain AML and countering the financing of terrorism (“AML/CFT”) programs, and—for the first time—explicitly mandate that a category of US persons maintain an effective sanctions compliance program. FinCEN and OFAC propose that the final rules become effective 12 months after issuance to allow PPSIs sufficient time to implement the requirements. Comments are due June 9, 2026.
