Article Summary: This article provides a comprehensive overview of the implementation of the GENIUS Act (Guiding and Establishing National Innovation for U.S. Stablecoins) in the first half of 2026, following its enactment in July 2025. It examines the regulatory rulemaking activities undertaken by the FDIC and the OCC, detailing specific proposals regarding reserve requirements, capital standards, interest prohibitions, and licensing pathways for stablecoin issuers. The article incorporates analysis from Sullivan & Cromwell and Mayer Brown, explaining the three pathways to becoming a permitted payment stablecoin issuer (PPSI) and the implications for institutional adoption. Key takeaways include the strict 1:1 reserve backing rules, the prohibition on passing yield to holders, and the broader significance of regulatory clarity for legitimizing stablecoins in cross-border payments and mainstream finance.
A defining moment for the crypto payments industry in 2026 is the full implementation of the Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act. Enacted in July 2025, this legislation established a federal regulatory framework for payment stablecoins, and the first half of 2026 has been characterized by a flurry of rulemaking activities as the January 18, 2027, effective date approaches.
In December 2025, the FDIC was the first to act, proposing application requirements for state nonmember banks seeking to issue stablecoins through subsidiaries . This was followed in February 2026 by a comprehensive proposal from the Office of the Comptroller of the Currency (OCC). The OCC’s proposal, published on February 25, 2026, establishes a new regulatory framework (12 CFR Part 15) that covers everything from licensing and permissible activities to reserves, risk management, and capital requirements for national banks, federal savings associations, and nonbank entities seeking to become “Federal qualified payment stablecoin issuers” (FQPSIs) .
The OCC’s proposal is particularly notable for its strict rules on reserve assets. It requires that issuers maintain a 1:1 backing of reserves, measured at fair value, which must consist of highly liquid assets like U.S. currency, short-term Treasury bills (93 days or less), and demand deposits . Importantly, the proposal explicitly excludes other cryptocurrencies or stablecoins from qualifying as reserve assets, ensuring that the backing is genuine and stable. It also introduces a quantitative safe harbor for reserve diversification, requiring that at least 10% of reserves be held as daily liquidity (demand deposits or Fed balances) and that the weighted average maturity of reserves not exceed 20 days .
One of the most contentious aspects of the OCC proposal is the prohibition on paying interest or yield to stablecoin holders. The OCC aims to ensure that stablecoins are treated as a means of payment rather than an investment vehicle. The proposal includes a “rebuttable presumption” that certain affiliate arrangements designed to pass yield to holders would violate this rule, closing potential loopholes that have been exploited by some offshore issuers .
The GENIUS Act offers three pathways to become a permitted payment stablecoin issuer (PPSI): through an insured depository institution (IDI) subsidiary (FDIC pathway), as a federal qualified issuer (OCC pathway), or as a state qualified issuer (state pathway). This multi-track system aims to provide flexibility while ensuring oversight. As noted by the World Economic Forum, this regulatory clarity is a key accelerator for adoption, giving businesses the confidence to scale their operations .
The implementation of the GENIUS Act is expected to reshape the stablecoin landscape. By providing a clear, federal framework, it encourages institutional participation and offers consumer protections that were previously lacking. For cross-border payments, this regulatory certainty could legitimize stablecoins as a mainstream alternative to traditional wire transfers, potentially reducing costs and settlement times significantly . As the July 18, 2026, deadline for final regulations approaches, the industry is watching closely to see how these rules will interact with state laws and international standards, setting the stage for the next phase of digital dollar innovation.
