This bill, known as the "GENIUS Act of 2025," establishes a comprehensive regulatory framework for payment stablecoins in the United States. It defines a payment stablecoin as a digital asset designed for payment or settlement, whose issuer is obligated to maintain a stable value relative to a fixed monetary value, and explicitly states it is not a national currency, deposit, interest-bearing asset, or security. The legislation aims to ensure the stability and integrity of the stablecoin market by mandating that only "permitted payment stablecoin issuers" can issue these assets. Permitted issuers, which include subsidiaries of insured depository institutions, federal qualified nonbank entities, and state qualified entities, must maintain 1:1 reserves of highly liquid assets. These reserves are limited to U.S. coins and currency, Federal Reserve accounts, short-term Treasury bills, certain repurchase agreements, and money market funds invested in such assets. Issuers are also required to publicly disclose their redemption policies, establish timely redemption procedures, and publish monthly reports on their reserve composition. The bill prohibits the rehypothecation of reserves, with limited exceptions, and mandates monthly examinations of reserve reports by registered public accounting firms, with CEO/CFO certifications. Primary federal and state regulators will jointly issue tailored capital, liquidity, and risk management requirements for issuers. Furthermore, permitted payment stablecoin issuers are designated as financial institutions under the Bank Secrecy Act, subjecting them to stringent anti-money laundering, sanctions compliance, and customer identification obligations. A dual regulatory system is established, allowing state-qualified issuers with less than $10 billion in outstanding stablecoins to operate under state-level regimes, provided they are substantially similar to federal standards. State-regulated issuers exceeding this threshold must transition to federal oversight or cease new issuance, though waivers are possible. The bill also clarifies that payment stablecoins are not backed by the full faith and credit of the U.S. government or federal deposit insurance, and misrepresenting this is unlawful. Federal regulators are granted supervisory and enforcement powers, including the ability to suspend issuance, issue cease-and-desist orders, and impose civil penalties for violations. In insolvency proceedings, claims of stablecoin holders against required reserves are given priority over other creditors, and the bill amends the U.S. Bankruptcy Code to facilitate this. Additionally, the Treasury Department can designate non-compliant foreign stablecoin issuers and prohibit their secondary trading in the U.S. The legislation limits permitted stablecoin issuers to core activities like issuance, redemption, and reserve management, prohibiting tying arrangements. It also clarifies that payment stablecoins issued by permitted entities are explicitly not considered securities under various federal acts, nor are they commodities. The bill mandates studies on non-payment stablecoins and requires the Treasury to pursue reciprocal arrangements with foreign jurisdictions to facilitate international stablecoin transactions.
