The GENIUS Act's first anniversary passed without a single final rule as the stablecoin market grew to $308B, exposing issuers to regulatory uncertainty.
The GENIUS Act reached its first anniversary July 18 with no final rules in place. The statutory deadline for payment stablecoin regulations passed as eight proposals remained pending across four federal agencies.
Over the same year, the stablecoin market grew from $259.7 billion to $308.1 billion. That 18.6% increase happened entirely under unfinished regulatory guidance.
On-chain data from July 19 showed total supply had climbed to a May peak above $320 billion before settling at $308.1 billion. The market added $48 billion in new tokens without a finished legal framework.
Four agencies hold responsibility for writing the rules. The OCC proposed a broad implementing rule in March covering reserves and capital requirements, along with custody standards. The FDIC and NCUA submitted separate prudential and licensing proposals. Treasury addressed state-level regulation in April. None has completed the process.
Market concentration amplifies the stakes. USDT and USDC together control about 83% of the stablecoin market. Any final rule directly shapes their operations. USD1, the World Liberty Financial token, has grown into the fifth-largest stablecoin over the past year.
An institutional cohort expanded inside the regulatory gap. PayPal's PYUSD, BlackRock's BUIDL, Ripple's RLUSD and Paxos-backed USDG all grew without finished federal guidance. These issuers built market share while the rules meant to govern them remained in draft.
Congress built a backstop into the original legislation. The Act takes effect on the earlier of January 18, 2027, or 120 days after final rules publish. Since no rule finalized after September 20 can move that date earlier, January 18 now stands as the effective start.
Draft proposals outline requirements without legal force. Reserves must sit one-to-one in cash and short-dated Treasuries. Redemptions would need processing within two business days, alongside a five-million-dollar capital floor from the OCC language.
Issuers face different exposure. Circle's USDC has the most riding on final capital and reserve requirements. Tether launched USAT, a US-compliant token, anticipating rules that remain unpublished.
Stablecoins function as the settlement layer beneath most crypto market activity. Every DEX pair and on-chain treasury operates on infrastructure lacking finished US legal grounding. The market added $48 billion in new supply without waiting for regulatory certainty.
