Proposed U.S. Treasury rules place the burden of foreign stablecoin compliance on American crypto exchanges and digital-asset service providers. S. Department of the Treasury has unveiled proposed rules that significantly shift the burden of policing foreign stablecoin compliance directly onto American crypto exchanges and other digital-asset service providers. Under the new guidance for the Guiding and Establishing National Innovation for U.S.
Stablecoins Act (GENIUS Act), platforms must conduct “reasonable due diligence” to ensure foreign issuers can comply with lawful U.S. orders, or face potential delisting and significant penalties.
Foreign stablecoin compliance and reasonable diligence
Published on August 18, 2026, the Notice of Proposed Rulemaking (NPRM) effectively makes U.S.-based companies the gatekeepers for access to the American market. It mandates that any exchange listing a foreign-issued payment stablecoin must be able to defend its decision to trust the issuer.
The public comment period on these far-reaching rules is set to close on October 19, 2026, providing the industry a tight window to offer feedback.
The core of the Treasury’s proposal centers on the “reasonable due diligence” standard. This isn’t a simple procedural check, however. U.S. platforms will be barred from relying on a foreign issuer’s compliance promises if they know, or have reason to know, that the representation is false or that the issuer cannot or will not comply.
The rule demands that exchanges consider all reasonably available information about an issuer’s ability and willingness to adhere to U.S. legal orders, such as freezing or seizing assets when required. This goes beyond merely checking if an issuer appears on a public prohibitions list under the GENIUS Act.
Treasury officials clarified that while such a check is a minimum requirement, it is not sufficient on its own.
This move signals a significant change in regulatory posture, effectively deputizing the private sector to enforce standards on global stablecoin operators. Platforms are now directly responsible for vetting the foreign stablecoins they make available to U.S. customers, a critical step toward redefining market access and accountability within the digital asset space.
For exchanges that fail to comply, the stakes are high. The GENIUS Act imposes a civil penalty of up to $100,000 per violation, per day, for any provider that knowingly facilitates trading in a stablecoin subject to a prohibition. This financial threat aims to ensure that platforms take their new gatekeeping role seriously, fundamentally altering the risk calculation for listing foreign stablecoins.
A two-phase timeline for stablecoin oversight
The Treasury has structured the implementation of these rules across a two-part timeline, creating a transitional period before the full weight of the law takes effect. This phased approach allows the market time to adapt while clearly signaling the long-term regulatory direction for payment stablecoins.
The first phase is expected to begin on January 18, 2027. From this date, the general regime of the GENIUS Act, including the platform-level due diligence requirements, will become active. U.S. exchanges and digital asset providers will need to have their vetting processes for foreign stablecoins in place and be ready to defend their listings based on this new standard.
The second, more stringent phase begins on July 18, 2028. After this date, the rules become much tighter for foreign issuers themselves, requiring them to meet specific criteria to be offered in the U.S. market.
This demonstrates a clear intent to bring the entire stablecoin ecosystem into regulatory alignment, focusing on both access points and issuer qualifications. Questions remain about what constitutes adequate platform diligence in practice, such as requirements for smart-contract reviews.
Stricter issuer requirements will be enforced
Starting in mid-2028, a foreign stablecoin can only be offered to U.S. customers if its issuer meets a demanding set of criteria. The issuer must be supervised under a foreign regulatory regime that the Treasury deems “comparable” to U.S. standards. It will also need to register with the Office of the Comptroller of the Currency (OCC).
Furthermore, the foreign issuer must hold sufficient reserves at a U.S. financial institution to cover its liabilities to American customers, unless a specific reciprocal agreement is in place. Critically, issuers from jurisdictions under comprehensive U.S. sanctions or designated as a “primary money laundering concern” will be barred entirely. These issuer-level tests will exist alongside the ongoing platform diligence requirements, creating multiple layers of scrutiny.
What the proposed rules will not change
Despite the robust new framework, the Treasury’s proposal is not a blanket prohibition on foreign stablecoins. The rules include specific exemptions to protect individual users and common peer-to-peer activities. Lawful direct transfers between individuals without an intermediary are explicitly carved out, preserving a core use case of cryptocurrency.
The regulations also will not apply to transactions conducted via self-custody software or hardware wallets, where individuals manage their own assets. Additionally, certain transfers between a U.S. person’s domestic and foreign accounts under the same parent company are exempt. This nuanced approach focuses regulatory attention on the intermediaries that provide broad market access, rather than on individual users.
Importantly, the Treasury has not created a “white list” or “black list” of specific stablecoins. The announcement does not mention Tether (USDT) or any other major foreign stablecoin by name. Instead, the proposal creates a principles-based standard, leaving it to individual exchanges to gather evidence and make a risk-based assessment on each asset they support.
Industry on deadline as key questions remain
The proposal has left several critical questions open for public comment, giving the crypto industry a chance to shape the final regulations. Treasury Secretary Scott Bessent noted the agency is “moving quickly to implement that framework” established by “President Trump and Congress,” underscoring the political will behind the initiative. The agency is seeking feedback on what constitutes “adequate” diligence.
Specific points under consideration include whether the final rule should mandate written and regularly updated representations from issuers, impose strict record-retention policies, or even require platforms to conduct their own smart-contract reviews.
The Treasury is also weighing whether to require verification of an issuer’s technical ability to freeze, seize, and burn tokens as directed by lawful orders. These questions aim to solidify a framework that balances innovation with financial stability and consumer protection for the stablecoin sector, providing clarity through future regulations.
This period of public comment, ending October 19, represents a pivotal moment. The feedback received could significantly influence how burdensome the final compliance regime will be. For foreign stablecoin issuers, the message is clear: the era of largely unregulated access to the U.S. market is ending. They must now prepare to provide unprecedented transparency and technical compliance to remain part of the world’s largest economy.
The Treasury’s proposals represent a proactive step to manage risks associated with digital assets. It aims to ensure that as the stablecoin market evolves, it does so within a framework that protects U.S. interests and consumers, aligning with the broader goals of the GENIUS Act.
This regulatory push could redefine the operational landscape for all digital asset service providers engaging with the U.S. market, ultimately fostering greater market stability and trust.
