Stablecoin Rulebook Comes Due as GENIUS Act Deadline Nears

The GENIUS Act (the 2025 United States law that created a federal framework for payment stablecoins) reaches its one-year mark on July 18, the date by which six federal agencies must publish final rules. Industry executives quoted by CryptoSlate view the deadline less as a milestone of legitimacy and more as a test of compliance costs, one that reveals which issuers can afford full reserve, audit, and disclosure requirements and which cannot. Under the statute, only a permitted payment stablecoin issuer may mint a dollar token in the country, while exchanges and custodians may keep distributing non-permitted tokens until roughly July 2028.

The stakes are set by scale. Total stablecoin supply now stands near $309.9 billion, with Tether's USDT at about $184.03 billion and Circle's USDC at about $73.25 billion. That concentration means the rulebook effectively arbitrates an existing duopoly rather than an open field. Reserves held in short-dated Treasury bills tie that supply directly to United States government funding markets.

The International Monetary Fund added a note of caution the same day, warning that moving assets onto blockchains can make finance faster and cheaper while also leaving it more susceptible to sudden shocks. Viewed through a sound-money framework, the deadline institutionalizes private dollar liabilities at the moment their systemic footprint is large enough to matter. The compliance floor it sets will determine whether the market widens or narrows around two incumbents.
