US Treasury Proposes Stablecoin Regulation Under GENIUS Act

The proposed regulations will define how stablecoins are issued and sold, impacting both domestic and foreign digital asset markets.

• On August 17, 2026, the US Treasury issued a Notice of Proposed Rulemaking to clarify stablecoin issuance under the GENIUS Act.
• The proposal establishes compliance standards for both domestic and foreign issuers, with public comments open for 60 days.
• Sales prohibitions for non-compliant issuers will begin on July 18, 2028, creating a timeline for adaptation.

• The GENIUS Act, signed into law in July 2025, aims to create a federal framework for payment stablecoins, mandating 1:1 reserves.
• Previous regulatory steps included an Advance Notice of Proposed Rulemaking in September 2025 and joint proposals addressing anti-money laundering compliance.
• The current proposal focuses on defining when a stablecoin is considered issued in the US, based on the issuer's location and the recipient's location.

The US Treasury's proposed rulemaking on stablecoins is a significant step in establishing a regulatory framework that aims to bring clarity and compliance to the burgeoning digital asset market. The GENIUS Act, which underpins this proposal, was designed to ensure that stablecoins are backed by tangible reserves, such as cash and short-term Treasury securities, thereby enhancing consumer protection and market stability.

The proposed regulations define a stablecoin as issued in the US if the issuer is located domestically or if the recipient is based in the US. This determination hinges on physical presence for individuals and the incorporation or principal place of business for entities. For foreign issuers, the regulations provide a pathway to avoid US issuance treatment by demonstrating a reasonable belief that their recipients are non-US based, implementing preventive controls, and refraining from targeted advertising to US users.

Digital asset service providers are also affected, facing similar compliance requirements. The proposal includes safe harbor provisions that allow for certain peer-to-peer transfers and self-custody transactions to be exempt from these regulations. However, the Treasury is seeking public feedback on how these rules might apply to various activities, including airdrops, buybacks, and market-making.

The implications of these regulations are profound. They not only set the stage for how stablecoins will be treated under US law but also influence how foreign issuers and digital asset platforms operate. Companies may need to implement geo-fencing, IP controls, or Know Your Customer (KYC) measures to ensure compliance, particularly if they serve American users. This could lead to increased operational costs and complexity for businesses that wish to maintain access to the lucrative US market.

As the comment period unfolds, stakeholders will have the opportunity to voice their concerns and suggestions, which could lead to adjustments in the final rule. The Treasury's ongoing efforts to refine these regulations reflect a broader commitment to ensuring that the digital asset ecosystem operates within a framework that promotes transparency and accountability.

• Stablecoin issuers: Must adapt to new compliance standards or face sales prohibitions.
• Digital asset service providers: Need to implement measures to ensure compliance with US regulations.
• Consumers: May experience changes in access to stablecoin services and potential costs associated with compliance.
• Foreign issuers: Must demonstrate technological capabilities to comply with US orders to maintain market access.

• Public feedback outcomes: The responses to the proposed rulemaking could lead to significant changes in the final regulations, impacting compliance costs and operational strategies.
• Implementation timeline: Monitor the transition period leading up to the sales prohibitions starting in July 2028, as companies prepare for compliance.
• Market reactions: Watch for shifts in stablecoin usage and issuer strategies as the regulatory landscape evolves.
