Summary
The GENIUS Act, signed into law July 18, 2025, creates a mechanism generating roughly $10 billion in annual income for stablecoin issuers at current market rates. With $290-300 billion in stablecoins in circulation, issuers must back every token 1:1 with high-quality assets. The Act explicitly allows issuers to park reserves inside regulated money market funds while prohibiting them from passing any yield to holders. State Street launched its Stablecoin Reserves Money Market Fund in June 2026, one of the first products engineered for GENIUS Act compliance.
Key Facts
- $10B annual income at 3.5% yield on $290-300B stablecoin market cap
- Issuers prohibited from passing yield to holders — tokens defined as payment instruments, not interest-bearing products
- State Street launched dedicated MMF for GENIUS-compliant reserve parking in June 2026
- Senate passed GENIUS Act 68-30 — unusually broad bipartisan agreement
- Treasury, FDIC, OCC finalizing AML, capital, and reserve rules by July 2026
- Key risk: Fed rate cuts compress the $10B figure significantly
Why It Matters
The GENIUS Act transforms stablecoin issuance from a gray-area business into a federally sanctioned, structurally profitable one. The prohibition on holder yield means issuers capture all Treasury income — a design that makes stablecoins more like payment rails than savings products. The rate dependency creates a structural risk: if the Fed cuts rates, issuer margins compress. This also sharpens the line between regulated payment stablecoins and DeFi protocols that offer holder yield.
