On July 18, 2025, President Trump signed the GENIUS Act (Guiding and Establishing National Innovation for US Stablecoins) into law — the first piece of federal US legislation specifically targeting stablecoins. It means that stablecoins circulating in the United States now have federal-level rules: who can issue them, how reserves must be held, and whether issuers can pay yield to holders. The implementing rules are still rolling out, and 2026 is the key year as regulators finalize the details.
The GENIUS Act's central concept is the PPSI (Permitted Payment Stablecoin Issuer). The law says only entities with PPSI status may issue payment stablecoins in the US, via three pathways: an OCC federal license, being a compliant bank subsidiary, or state regulation (for issuers up to $10B, provided state rules are “substantially similar” to federal). Issuers must hold reserves 1:1 in cash or short-term Treasuries, keep assets segregated, publish monthly independent attestations, and run full AML/KYC programs.
The GENIUS Act explicitly bars payment stablecoin issuers from paying interest or yield to holders, with the logic of “not letting stablecoins become deposits without a banking license.” This directly hits several existing products: PYUSD's up-to-4% reward program faces compliance pressure, and staked yield products like sUSDS and sUSDe are classified as separate instruments (DeFi derivatives) rather than payment stablecoins, leaving them in a regulatory gray zone for now.
Circle (USDC) already operates under the OCC regulatory framework and has the clearest compliance path. Paxos (PYUSD) holds an OCC federal trust charter and is well-aligned. Sky (USDS) takes a DeFi approach and has not received EU MiCA authorization either, making it the most ambiguous under the GENIUS Act's federal structure. The biggest question mark is USDT: Tether is registered in the British Virgin Islands, its reserve transparency has long been questioned, and it currently qualifies neither as a PPSI nor as a compliant foreign issuer — if ultimately barred from legal sale in the US, the impact on the world's largest stablecoin (around $188B market cap) would be significant.
The GENIUS Act's short-term impact on retail holders is limited — it regulates issuers, not end users. But three things are worth watching. First, reserve protection for compliant stablecoins is clearer than before: mandatory 1:1 reserves, independent audits, and asset segregation make USDC and its peers more transparent. Second, if you hold large amounts of USDT, watch Tether's compliance progress: if it is eventually restricted from US trading, liquidity could be affected. Third, yield products will increasingly be positioned as DeFi derivatives rather than stablecoins, meaning they operate under a different regulatory framework with different protections. All rules are still in draft; the final effective date is no later than January 18, 2027. Until then, periodically check the compliance status of the stablecoins you hold.
