The GENIUS Act, Explained: What America's First Stablecoin Law Actually Requires

On July 18, the GENIUS Act became law, making the United States the largest economy to adopt a dedicated federal regime for payment stablecoins. The bill passed the Senate in June with a comfortable bipartisan margin and cleared the House in the same week that Washington branded as 'crypto week.' The headlines focused on the politics. The more durable story is in the text: a set of rules that will determine what a legal dollar token looks like, who may issue one and how much of the world's digital money ends up anchored to US Treasury bills.

The core rules in plain language

The law defines a 'payment stablecoin' as a digital asset designed to be used for payment or settlement, redeemable at a fixed monetary value. Only permitted issuers may offer such tokens to people in the United States. Those issuers fall into a few categories: subsidiaries of insured banks, federally licensed non-bank issuers supervised by the Office of the Comptroller of the Currency, and state-licensed issuers, which are allowed below a size threshold of roughly ten billion dollars in outstanding tokens as long as the state regime is judged substantially similar to the federal one.

Reserves are the heart of the design. Every token must be backed at least one to one by a narrow list of assets: cash, demand deposits, Treasury bills with short maturities, overnight repurchase agreements backed by Treasuries, and government money market funds investing in the same. Rehypothecation is largely prohibited. Issuers must publish the composition of their reserves monthly, with the figures examined by a registered accounting firm, and larger issuers face annual audited financial statements.

The no-interest clause and the banking lobby

One provision has already become a flashpoint. Issuers may not pay interest or yield to holders simply for holding the token. That was a concession to banks, which feared that a yield-bearing digital dollar would pull deposits out of the banking system. Critics note that the ban applies to the issuer but not necessarily to exchanges or affiliates that offer 'rewards' on stablecoin balances, and banking groups are already lobbying regulators to close that gap. How this is interpreted will shape whether stablecoins remain a payment tool or evolve into a quasi-savings product.

Foreign issuers and the offshore question

The largest dollar stablecoin in circulation is issued outside the United States. The GENIUS Act addresses this indirectly. A foreign issuer can serve US users only if its home regime is deemed comparable by the Treasury, if it registers with US authorities, holds sufficient reserves in US institutions to meet domestic redemptions and can comply with lawful orders to freeze tokens. After a transition period, US service providers will be barred from offering non-compliant tokens. In effect, Washington is using market access to export its standards.

The practical effect is to hand the Treasury a significant lever. If an offshore issuer wants continued access to American exchanges, payment firms and custodians, it will need to show that its reserves, audits and compliance controls meet a bar set in Washington. Some offshore issuers have already signaled that they intend to launch separate US-compliant products rather than bring their flagship tokens under the new regime, which could split the market into onshore and offshore versions of the same dollar. For users outside the United States, the distinction may matter little day to day. For regulators, it creates a clear line between tokens they can supervise and tokens they can only watch.

That export is the geopolitical core of the law. Policymakers have been frank that they expect dollar tokens to add demand for Treasuries and to reinforce the dollar's role in digital commerce. Market watchers already describe the stablecoin sector as one of the faster-growing sources of demand for short-term government paper, with total supply now in the low hundreds of billions of dollars.

The law does not just regulate a product. It wires a new source of demand directly into the US Treasury market.

What the law leaves open

• Timing: most provisions take effect 18 months after enactment or 120 days after final regulations, whichever comes first, so the rulemaking calendar matters.
• Big tech: public companies not primarily in finance face extra hurdles, but the line will be tested.
• Market structure: the broader question of which agency oversees crypto trading remains with a separate bill.
• Run risk: reserves are high quality, but a very large issuer selling bills in a panic would still stress markets.

It also arrives in a crowded global field. The EU's MiCA rules for e-money tokens have applied since mid-2024. Hong Kong's stablecoin ordinance took effect on August 1, with licensing by the Hong Kong Monetary Authority that is expected to be selective. Other jurisdictions, from Singapore to the UK, are finalizing their own approaches. Issuers that want to operate globally will face overlapping and sometimes conflicting requirements.

Bottom line

The GENIUS Act ends the era in which dollar stablecoins lived in a legal gray zone in the United States. It chooses a narrow-bank model for reserves, preserves the separation between payment tokens and interest-bearing deposits, and uses access to the US market as leverage over offshore issuers. The unfinished parts, from yield loopholes to the treatment of technology giants, will be fought over in rulemaking. Readers should treat this as an explainer of policy, not a recommendation about any token or issuer.
