Stablecoin issuers keep roughly $10B annually from reserve yields under new federal rules. Holders get no interest. State Street launched a compliance fund.
Alpha Score of 69 reflects moderate overall profile with strong momentum, moderate value, moderate quality, moderate sentiment.
The GENIUS Act, signed into law July 18, 2025, created the first federal framework for payment stablecoins in the US. One provision generates roughly $10 billion in annual income for issuers at current rates. None of that yield reaches the people holding the tokens.
Issuers must back every token with a 1:1 reserve of cash, short-term US Treasuries, or similar assets. The Act explicitly permits parking those reserves in regulated money market funds. With roughly $290 billion to $300 billion in stablecoins circulating – mostly Tether's USDT and Circle's USDC – a 3.5% yield on those reserves produces the near-$10 billion figure.
The Act simultaneously prohibits issuers from passing any of that yield to holders. The tokens are legally defined as payment instruments, not interest-bearing products. Holders get a stable dollar. Issuers get the Treasury income.
Financial institutions moved quickly once the framework was in place. State Street launched its Stablecoin Reserves Money Market Fund in June 2026, one of the first products engineered for GENIUS Act compliance. The fund holds reserve assets backing payment stablecoins while meeting the Act's eligibility requirements.
The Senate passed the GENIUS Act 68-30, a margin reflecting bipartisan agreement on a crypto-related measure. The bill was introduced in May 2025. Rulemaking is ongoing. The Treasury, FDIC, and other regulators are expected to finalize rules on anti-money laundering compliance, capital standards, and reserve requirements. Several final rules are anticipated by July 2026.
For stablecoin issuers, the GENIUS Act turns a previously gray-area business into a federally sanctioned, structurally profitable one. The 1:1 reserve requirement removes the opacity that surrounded Tether for years. The interest rate dependency is the key risk. At 3.5%, the math works. If the Federal Reserve cuts rates significantly, that $10 billion figure compresses.
For holders, the prohibition on yield payments means stablecoins remain purely transactional instruments under this framework. What holders do get is a federally mandated assurance that the reserves backing their tokens are held in compliant, auditable assets.
Traders and DeFi participants should watch how the yield prohibition interacts with decentralized stablecoin protocols that offer holders a return. Those products exist in a different regulatory category for now. The GENIUS Act draws a sharp line between payment stablecoins and everything else. That distinction will matter as regulators continue filling in the framework through 2026.
