Federal regulation reshapes $300bn US stablecoin market
New federal rules and OCC trust charters are formalizing the $300 billion stablecoin market as a regulated parallel to traditional banking, though structural differences in reserve backing and yield distribution keep the two systems distinctly separate.
The US stablecoin market has transitioned from a patchwork of state licenses to a unified federal framework following the enactment of the GENIUS Act in July 2025. Building on that law, the Office of the Comptroller of the Currency granted conditional national trust bank charters to Circle, Paxos, and Ripple in December 2025. These moves formally integrate dollar-backed digital tokens into the federally supervised financial system.
The industry is now a roughly $300 billion duopoly dominated by Tether’s USDT and Circle’s USDC, which together account for close to 90% of the market. Smaller entrants like PayPal’s PYUSD and bank-linked tokens make up the remainder. For investors and institutions, stablecoins offer a mechanism to move dollars globally in seconds, bypassing the multi-day delays and weekend closures of traditional correspondent banking networks.
Unlike traditional banks that operate on fractional reserves and lend out customer deposits, stablecoin issuers under the GENIUS Act must hold liquid assets equal to every token outstanding. This full-reserve model eliminates the theoretical risk of a bank run, a vulnerability that famously collapsed Silicon Valley Bank in 2023 when depositors attempted to withdraw $42 billion in a single day. However, stablecoins introduce different risks, as seen in March 2023 when USDC lost its peg after $3.3 billion of its reserves were trapped in that same failed bank.
To prevent stablecoins from draining traditional bank deposits, the GENIUS Act explicitly prohibits issuers from paying interest or yield to token holders. If a compliant stablecoin offered 4% while standard checking accounts offered less, capital would rapidly exit the banking system. Issuers like Circle retain the interest generated by their reserve assets, though distribution platforms like Coinbase can still offer rewards to users by sharing that reserve income with the issuer.
Federal supervision brings new transparency requirements, but differences remain between major issuers. Circle publishes audited financial statements and holds its reserves in a BlackRock-managed government money market fund. Tether relies on quarterly attestations rather than full audits and backs USDT with a mix of Treasuries, gold, bitcoin, and secured loans. Furthermore, unlike bank deposits which carry FDIC insurance up to $250,000, stablecoins lack a government backstop and remain subject to centralized freezing mechanisms written into their smart contracts.
