GENIUS Act's Synthetic Stablecoin Carve-Out May Create an Unintended Regulatory Gap

A close reading of the GENIUS Act’s payment stablecoin definition suggests that language designed to exclude crypto-backed synthetic coins such as Sky’s USDS and Ethena’s USDe may also create a broader escape route from the Act’s requirements than its drafters likely intended.

The mechanism turns on how redemption is defined. Under the Act, a payment stablecoin issuer must be obligated to redeem its coin for a fixed amount of monetary value, with an explicit carve-out stating that redemption into another digital asset denominated in a fixed monetary amount does not qualify. The practical effect is that any coin whose redemption path leads to another stablecoin rather than to fiat currency falls outside the definition entirely. USDS, which redeems into USDC rather than directly into cash, fits that description and so neither it nor its issuer would be subject to the Act’s permitting requirements.

The concern raised is that the same definitional boundary could be exploited beyond the synthetic-coin context. If wrapping an otherwise unlawful foreign stablecoin in a wrapper that only redeems into another digital asset is sufficient to take the wrapper outside the Act’s scope, that wrapper could potentially circulate in US markets without triggering the regulatory obligations the Act was built around. Whether that reading survives legislative scrutiny or regulatory interpretation remains an open question, but it is a structural ambiguity worth tracking as the Act advances.
