Treasury Unveils Certification Rule for Stablecoin Regulators Under GENIUS Act

On September 30, 2026, the U.S. Department of the Treasury's interim final rule on stablecoin regulation took effect, introducing a new certification process for state payment stablecoin regulators under the GENIUS Act.

The rule formalizes the form and procedure for state regulators to gain federal approval, directly impacting businesses that use stablecoins for payments, payroll, and working capital.

State payment stablecoin regulators must demonstrate that their supervisory and examination framework meets federal standards, covering reserve composition, redemption, disclosure, and operational safeguards.

The Stablecoin Certification Review Committee reviews the submitted forms and supporting materials, issuing an approval or denial. A successful certification means stablecoins issued under a state's regime become federal payment stablecoins, gaining access to the federal payment system and satisfying key compliance requirements.
