The U.S. stablecoin market entered a new regulatory era on April 1, 2026, as the GENIUS Act (Guiding Establishment and National Integration of Stablecoins Act) came into full effect. This landmark legislation, jointly implemented by the U.S. Department of the Treasury and the Office of the Comptroller of the Currency (OCC), marks the first comprehensive federal framework for payment stablecoins, targeting issuers that collectively manage over $100 billion in circulation.
30-Day Registration Window Opens for Major Issuers
The Treasury and OCC have opened a 30-day window for "Permitted Payment Stablecoin Issuers" (PPSI), requiring Circle, Paxos and other major players to submit compliance applications. Under the Act, all stablecoins must be fully backed by cash or short-term U.S. Treasuries at a 1:1 ratio, ending the era of partially collateralized or algorithmically stabilized coins. This provision directly addresses the trust deficit left by the 2022 Terra collapse and aims to restore confidence in dollar-pegged digital assets.
Dual Federal-State Framework Sparks Regulatory Arbitrage Fears
The GENIUS Act introduces a dual federal and state regulatory framework. Stablecoins with issuance volumes below $10 billion may operate under state-level regulations deemed "substantially equivalent" to federal standards, allowing smaller issuers to avoid direct OCC oversight. However, think tanks including CSIS and the Brookings Institution warn this structure could encourage regulatory arbitrage, as issuers might deliberately cap their supply to remain under the threshold while choosing less stringent state regimes. States have 180 days to prove their rules match federal requirements or lose jurisdiction over small issuers.
Short-Term Treasury Market Feels the Heat
The Act's reserve mandate is expected to reshape the short-term Treasury market. As compliant stablecoins ramp up holdings of T-bills to meet the 1:1 requirement, demand for short-dated government debt could surge by an estimated $50–80 billion per year, according to Bloomberg analysts. This influx threatens to depress short-term yields by 5–10 basis points on 2-year notes, while banks may face deposit outflows as funds migrate to regulated stablecoin ecosystems. The OCC has signaled it will monitor market dynamics closely to prevent unintended dislocations.
Next 90 Days: Critical Period for Structural Realignment
The GENIUS Act is widely regarded as a watershed moment for U.S. stablecoins. OCC officials anticipate significant structural realignment within the next 90 days, as non-compliant offshore stablecoins exit the U.S. market and compliant issuers compete for dominance. UBS analysts note the Act redefines what constitutes "digital legal tender USD" and clarifies who is authorized to issue it. Additional implementation guidelines on reserve audits, cross-state coordination, and consumer protection are expected in the coming months.
While the registration window is now open, major issuers like Circle and Paxos have not yet publicly confirmed their PPSI filings. Meanwhile, the Senate Banking Committee is reviewing the CLARITY Act, which could complement GENIUS by addressing stablecoin yield compliance. Investors should monitor the 90-day window for issuer announcements and potential market volatility as the new regime takes shape.
