OCC's Stablecoin Rule: A Critical Step

Treasury’s Stablecoin Rulemaking Comment Period Closes Amidst Regulatory Uncertainty

The U.S. Department of Treasury’s Notice of Proposed Rulemaking (NPRM) concerning the issuance, offer, and sale of payment stablecoins concluded its public comment period on October 19, 2026. The Treasury solicited industry feedback on 87 questions, covering critical areas such as issuer licensing, access for foreign stablecoins, reserve composition, and due diligence requirements for exchanges. However, the closure of the comment window does not signify the finalization of the regulatory framework; a binding rulebook remains absent.

GENIUS Act Deadlines Loom as Final Rules Lag

President Trump signed the Guiding and Establishing National Innovation for U.S. Stablecoins Act (GENIUS Act) into law on July 18, 2025. The legislation mandated that regulators finalize implementing rules by July 18, 2026, approximately one year after its enactment. This deadline passed without any final rules being published by the Treasury, the Office of the Comptroller of the Currency (OCC), the Federal Deposit Insurance Corporation (FDIC), or the Federal Reserve.

The statutory effective date for the Act is set for January 18, 2027, which is 18 months after enactment, or 120 days after primary federal regulators issue their final rules, whichever comes first. Given the missed July 2026 rulemaking deadline, the January 18, 2027 date now serves as the operative backstop. As of today, the OCC has yet to release its final rule, meaning the 120-day countdown has not commenced.

OCC’s Timeline and Potential Shift in Effective Date

The Comptroller of the Currency publicly stated on August 19, 2026, that the OCC anticipates publishing its final stablecoin rule by November 2026. If this timeline is met, the 120-day period would begin in November, pushing the effective date to approximately March 2027, which would be after the January 18 statutory backstop. Consequently, the January 18 date is no longer the latest possible effective date but rather the baseline scenario.

New Regulatory Framework for Stablecoin Issuers

The Treasury’s NPRM proposes establishing a new regulatory code under 12 CFR Part 1523. This framework will define the entities legally permitted to issue, offer, sell, or make payment stablecoins available within the United States. The GENIUS Act creates two qualifying categories: Permitted Payment Stablecoin Issuers (PPSIs) and Foreign Payment Stablecoin Issuers (FPSIs) that satisfy specific Section 18 requirements.

Market Cap Threshold and Regulatory Pathways

A market capitalization threshold of $10 billion serves as a structural dividing line. Issuers with a market cap below this figure may continue to operate under existing state regulatory frameworks. Conversely, issuers exceeding $10 billion will be mandated to transition to the federal OCC regime within 360 days of the effective date, or they may seek a formal exemption. Both USDT, with a global market capitalization of approximately $180 billion, and USDC, valued at around $72 billion, fall above this threshold.

Unresolved Questions and Due Diligence Standards

The Treasury’s NPRM posed 87 specific questions regarding implementation, regulatory scope, the treatment of foreign issuers, and compliance mechanisms. The sheer volume of these questions suggests that the Treasury has made foundational structural decisions but has yet to resolve all operational details. The comment period, which concluded today, was intended to gather answers to these 87 open questions before the final rule is drafted.

Foreign Stablecoin Access and Digital Asset Service Provider Obligations

Section 3(b)(2) of the GENIUS Act prohibits the offering, selling, or making available of foreign-issued stablecoins to U.S. persons unless the issuer can and will comply with lawful orders. This provision takes effect on January 18, 2027. The onus for ensuring compliance falls on digital asset service providers (DASPs), including exchanges and platforms, rather than directly on the issuer.

The Treasury acknowledged in its NPRM that a DASP might not have complete insight into a foreign issuer’s technological capacity to freeze funds in response to a U.S. lawful order and cannot be certain of future compliance. To avoid effectively barring platforms from offering any FPSI-issued stablecoins, the Treasury proposed a due diligence standard. Under this standard, platforms must have a reasonable basis to believe that the foreign issuer is capable of complying.

The “Gap” in Regulatory Timelines

An analysis by Freshfields, published on September 25, highlighted a significant “gap” between the January 18, 2027, effective date for Section 3(b)(2) (the due diligence requirement for exchanges) and the July 18, 2028, date for Section 3(b)(1) (the full prohibition on selling non-qualifying foreign-issued stablecoins to U.S. persons). This gap was identified as a primary focus for the comment period and now presents a challenge for regulators to resolve in the final rules.

USDC and USAT Poised for Compliance

USDC is issued by Circle, a U.S.-domiciled company that already provides monthly reserve attestations. Circle has submitted an application to the OCC for a trust bank license under the federal PPSI pathway. The existing reserve composition of USDC, comprising short-duration U.S. Treasuries and cash equivalents, aligns with the GENIUS Act’s reserve requirements without necessitating structural changes.

USDT is issued by Tether Limited, incorporated in El Salvador. Under the GENIUS Act, Tether is classified as a foreign issuer. The Act restricts foreign issuers from offering or selling stablecoins to U.S. persons unless the Treasury certifies that their home jurisdiction maintains comparable regulatory standards. As of October 19, 2026, no foreign jurisdiction, including El Salvador, has received such a comparability determination from the Treasury.

Tether’s Strategy and the Path Forward for USDT

Tether’s strategic response to this regulatory constraint was the launch of USAT (USA Tether) on January 27, 2026. USAT is a separate stablecoin issued by Anchorage Digital Bank, N.A., the sole federally chartered crypto bank in the U.S., with custody provided by Cantor Fitzgerald. USAT represents Tether’s U.S.-qualified instrument. The pathway for USDT to enter the U.S. market after January 18, 2027, hinges on a pending OCC comparability determination for El Salvador, for which no timeline has been provided.

USDT has until July 18, 2028, to achieve full compliance under Section 3(b)(1). However, the interim obligation under Section 3(b)(2), requiring exchanges to verify Tether’s ability to respond to lawful U.S. orders, becomes effective on January 18, 2027, just 91 days from today. Platforms currently listing USDT must possess a written compliance rationale for this listing by January 18 or face potential liability under the GENIUS Act’s enforcement provisions, which include fines of up to $1 million per knowing violation and imprisonment of up to five years.

A Multi-Pronged Regulatory Approach

The Treasury NPRM (RIN 1505-AC95), which closed today, is one of four regulatory documents being developed concurrently. FinCEN and OFAC issued proposed rules on anti-money laundering (AML) and sanctions on April 8, 2026, with a comment period that concluded on June 9. Rules concerning customer identification closed on August 21. The Treasury’s NPRM on issuance, offer, and sale concludes today. The OCC’s primary implementation rule, considered the most critical document for issuer licensing, is targeted for final publication in November 2026.

OCC’s Proposed Rule and Industry Response

The OCC’s proposed rule, published on February 25, 2026 (12 CFR Part 15), garnered 47 formal comments, including submissions from Visa, JPMorgan, and Coinbase, with three European central banks participating as informal observers by its May 1 closing date. The final rule will establish the Federal Qualified Payment Stablecoin Issuer (FQPSI) designation, define capital requirements for federally supervised issuers, and set redemption and disclosure standards. The operationalization of the GENIUS Act’s requirements for reserves and auditing will be addressed through this document.

Federal Reserve’s Role and Regulatory Asymmetry

The Federal Reserve’s proposed capital and redemption requirements for stablecoin issuers within its supervisory perimeter, specifically bank holding companies and state member banks, have not yet been finalized. If the Fed’s rule is published after the OCC’s November target, entities under Federal Reserve supervision will have less time to achieve compliance compared to those under OCC or FDIC jurisdiction. This disparity in regulatory timelines for supervised entities represents an unresolved structural asymmetry in the current implementation of the GENIUS Act.

The January 18 Backstop and Tiered Obligations

The January 18, 2027, backstop date triggers a tiered set of obligations. Section 3(b)(2), which mandates due diligence for DASPs regarding foreign-issued stablecoins, takes effect on this date. Platforms currently listing USDT must have a documented basis for believing that Tether can freeze funds in response to U.S. lawful orders. A comparability determination from the Treasury for El Salvador would resolve this issue, but none currently exists, nor has a timeline for one been established.

Penalties for Non-Compliance

Section 4(e)(3) of the GENIUS Act separately prohibits marketing a product in the U.S. as a payment stablecoin unless it is issued in compliance with the Act. Violations carry a fine of up to $500,000 per knowing and willful infraction. Section 3’s issuer prohibition carries more severe penalties, including fines of up to $1 million per violation and imprisonment for up to five years.

Global Regulatory Convergence and Compliance Challenges

The European Union’s Markets in Crypto-Assets (MiCA) regulation has an enforcement deadline for the removal of non-compliant stablecoins from exchanges scheduled for January 2027, running on a parallel timeline with the U.S. Both regulatory regimes are set to reach their hard enforcement dates within weeks of each other. In January 2027, stablecoin issuers and platforms operating globally will face simultaneous compliance obligations under both the U.S. GENIUS Act and the EU’s MiCA for the first time.

Regulatory Radar: Key Developments

Comments closed today on the Treasury’s proposal defining what constitutes a payment stablecoin issuer “in the United States.” The OCC has indicated that its final GENIUS Act rule is expected “in the very near term.” The Act’s effective date of January 18, 2027, looms regardless of these developments.

The Current Landscape: Compliance Without Final Rules

The comment window has closed, the OCC’s final rule has not been published, and no comparability determinations for foreign jurisdictions are in place. The GENIUS Act’s January 18, 2027, effective date is just 91 days away. The 120-day clock, which would extend the effective date by four months from the OCC’s publication, has not yet begun. Consequently, every stablecoin issuer, platform, and exchange operating in the U.S. market is currently adhering to a law for which the final operational rules are still pending.

USDT’s Uncertain Future

For USDT, the operational question presents a binary choice: either the OCC publishes a final rule before January 18, initiating the 120-day clock and pushing the effective date to approximately March 2027, thereby granting Tether additional time to pursue comparability, or the January 18 backstop takes effect without a comparability determination. In the latter scenario, U.S. platforms will need to independently assess whether they have a sufficient legal basis to continue listing USDT from that date.

USDC and USAT: Positioned for Compliance

In contrast, January 18 represents a compliance deadline that both USDC and USAT are structurally positioned to meet. Circle has already filed its OCC application, and USAT operates under a federally chartered issuer. The forthcoming binding rulebook is expected to formalize the competitive advantages these entities have built in anticipation of today’s regulatory landscape.
