The U.S. Department of the Treasury issued an Advance Notice of Proposed Rulemaking (ANPRM) seeking public comment to inform its implementation of the Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act, which tasks Treasury with issuing regulations for payment stablecoins. The ANPRM invites stakeholders to submit views, data, and other information relevant to a regime intended to encourage innovation while protecting consumers and addressing potential illicit finance and financial stability risks. Treasury noted that the ANPRM itself does not introduce new requirements under the GENIUS Act, but is intended to shape forthcoming implementation. Comments on the ANPRM are due within 30 days of publication in the Federal Register. Treasury also referenced its August 18, 2025 request for comment on innovative methods to detect illicit activity involving digital assets, which remains open until October 17, 2025.
