Summary
The US Treasury Department has issued a Notice of Proposed Rulemaking to implement the GENIUS Act, proposing federal definitions for what it means to issue US stablecoins and who needs to follow the rules. The proposal treats stablecoins as a new arena while studying established securities laws as a reference point, and notes that "application of traditional investment rules to payment stablecoins may frustrate" the goal of stablecoins serving as an effective means of payment and settlement, including across borders.
The proposed rule sets a two-stage timeline. Starting January 18, 2027, a person generally may not issue a payment stablecoin in the US without an appropriate federal or state license. By July 18, 2028, digital asset service providers may not offer or sell payment stablecoins to persons in the US unless issued by a licensed issuer — effectively putting a deadline on offshore stablecoins like Tether's USDT accessing US customers through regulated exchanges. The public has 60 days to comment.

Why It Matters
The Treasury proposal is the first detailed implementation of the landmark GENIUS Act and will determine how broadly the stablecoin framework applies. The 2028 deadline on offshore stablecoins is the most consequential element: it turns the exchange into the border, forcing US platforms to decide whether every stablecoin they carry has a valid regulatory route. This could concentrate the US market around domestic issuers like Circle and Paxos while reshaping Tether's US strategy — and it sets the competitive and compliance perimeter for the entire stablecoin industry.
