Stablecoin regulations crystallize as Circle and Coinbase draw focus

The GENIUS Act, signed into law on July 18, 2025, gave the US its first federal framework for payment stablecoin issuance. Follow-up proposals from the Office of the Comptroller of the Currency and the New York Department of Financial Services have since filled in the details. The picture is now concrete enough for institutional allocators to start building watchlists.

Issuers must hold 1:1 reserves in cash or short-term Treasuries, report monthly, and let holders redeem at par. The OCC and Treasury added proposed rules in April 2026 covering issuer licensing and mandatory audits, with the goal of aligning federal and state regimes.

On June 9, 2026, the NY DFS proposed its own rules to harmonize New York's existing state standards with the federal law. The NY DFS version keeps enhanced risk-management protocols and operates inside the federal framework. That is a change from the prior dual-regime model that forced issuers to choose between state and federal charters.

Circle Internet Group, issuer of USDC, said in a January 2026 report that regulated stablecoins are becoming core infrastructure for internet-native financial systems. Coinbase reported that over 25% of all USDC in circulation sat on its platform in Q1 2026. Base, Coinbase's layer-2 network, processed 62% of global on-chain stablecoin volume that quarter.

The EU's Markets in Crypto-Assets regulation, MiCA, already requires full reserve backing and licensed issuance. The US and EU landed on similar principles, so stablecoin issuers can build one product architecture for both markets. That saves costs for firms like Circle that operate across jurisdictions.

Forecasts from Standard Chartered and Bernstein project the total stablecoin market cap reaching roughly $1.2 trillion by end-2028, up from about $200 billion today. Most of that growth is expected in payments, where stablecoins compete directly with card networks and wire transfer rails.

Circle holds an Alpha Score of 28/100 and trades under the ticker CRCL on the NYSE as of its April 2026 IPO. The stock page draws attention from institutional desks that need exposure to stablecoin infrastructure but want a regulated equity vehicle rather than direct token holdings.

The OCC and NY DFS proposals are still open for comment. Final rules are expected in Q1 2027. The last open question is whether state-chartered issuers can keep their existing licenses under the federal umbrella.
