One year after Congress enacted the GENIUS Act, the first comprehensive U.S. framework for payment stablecoins, the market it was meant to govern is approaching $500 billion and Treasury is finalizing the rules that will bring it to life.

Signed into law in July 2025, the GENIUS Act established federal standards for privately issued payment stablecoins, a category of digital tokens pegged to the dollar and designed for everyday transactions. Until then, issuers operated in a patchwork of state regimes with little federal clarity.

The Treasury Department has since proposed a rule to implement the law's reserve, redemption and oversight requirements. The Office of the Comptroller of the Currency has also signaled how regulated banks might engage with permitted stablecoin issuers, a step that could pull traditional finance deeper into the space.

The legislation arrives as stablecoin usage broadens beyond crypto trading. Payment firms, remittance providers and retailers are exploring tokens for settlement, drawn by near-instant transfers and lower fees than card networks. Analysts estimate the total market could reach roughly $500 billion in 2026.

Supporters argue a clear U.S. framework will protect consumers and anchor dollar dominance in digital form. Critics counter that the law does too little to constrain systemic risk if a major issuer fails, and that linkages to the banking system deserve tighter guardrails.

With rules still being written, the coming months will test whether the GENIUS Act delivers on its promise of measured innovation. For an industry long starved of regulatory certainty, the direction of travel is now clearer than at any point in the past decade.
