Executive Summary 

• The Office of the Comptroller of the Currency (OCC) has finalized its rule implementing the GENIUS Act, establishing requirements for payment stablecoin issuers under its jurisdiction.  

• Two changes to the final rule are particularly significant: The OCC eliminated a proposed rebuttable presumption that certain third-party rewards arrangements violate the statutory prohibition on stablecoin yield and adopted a principles-based approach to reserve diversification and concentration supplemented by quantitative liquidity and counterparty limits. 

• Both changes reflect a preference for regulatory flexibility over a more prescriptive framework; they also leave questions about the boundaries of permissible stablecoin rewards, the appropriate treatment of competing financial products, and the extent to which agencies should determine consequential policy choices that Congress has left unresolved. 

Introduction 

The Guiding and Establishing National Innovation for U.S. Stablecoins (GENIUS) Act, enacted in July 2025, establishes a federal framework for payment stablecoins, including requirements for permitted issuers, reserve backing, redemption, and supervision. The Office of the Comptroller of the Currency’s (OCC) final rule, effective January 18, 2027, implements the act for issuers under its jurisdiction, including certain bank subsidiaries, federally qualified nonbank issuers, qualifying state issuers subject to OCC oversight, and foreign payment stablecoin issuers. It also establishes requirements for certain custody activities conducted by OCC-supervised entities. The rule addresses most of the OCC’s required implementing regulations, with Bank Secrecy Act, anti-money laundering, and sanctions requirements reserved for separate rulemaking. 

The final rule establishes standards governing permissible activities, reserve management, redemption, risk management, capital and operational backstops, audits, reporting, licensing, and ongoing supervision. The final rule also amends existing regulations concerning capital adequacy, prompt corrective action, assessments, and administrative proceedings. The OCC received more than 20 comments on its proposal and revised several provisions in response, particularly those concerning reserve management and the prohibition on stablecoin yield. The resulting framework combines statutory requirements and quantitative standards with substantial supervisory discretion. Two changes illustrate the implications of that approach. 

The Yield Prohibition: A Rule Without Defined Boundaries 

The GENIUS Act prohibits permitted payment stablecoin issuers from paying interest or yield solely in connection with holding, using, or retaining a payment stablecoin. The difficulty lies in determining when a payment described as a reward or commercial incentive is, in substance, prohibited yield. The OCC’s proposed rule addressed this question through a rebuttable presumption covering certain arrangements involving issuers and affiliates or related third parties. Under that approach, covered arrangements would be presumed prohibited, subject to an issuer’s ability to demonstrate otherwise. 

The final rule eliminates this presumption. The OCC concluded that it could capture permissible arrangements while failing to identify other arrangements that violate the statute, and that the resulting rebuttal process could impose compliance costs without a commensurate benefit. Instead, the agency will initially rely on applications, ongoing supervision, and enforcement, issuing additional guidance as appropriate and considering further rulemaking as it gains experience with the market. 

This approach preserves flexibility but leaves firms without clear prospective standards for distinguishing permissible transaction-based payments from prohibited yield. The OCC interprets the word “solely” to allow arrangements that serve a genuine purpose beyond holding, using, or retaining a stablecoin to fall outside the prohibition. That does not establish a categorical exemption for transaction-based rewards: The agency retains the authority to examine the substance of an arrangement and address attempts to evade the prohibition. The practical boundaries of the statutory rule will therefore depend in part on future supervisory judgements. 

There are arguments for this approach. The market is nascent, and a prescriptive framework could capture legitimate commercial arrangements or become obsolete as business models evolve. But the alternative is not costless. Issuers must assess the legality of rewards programs without knowing how the OCC will treat arrangements that have not yet been addressed. Removing the presumption may reduce one source of compliance burden while increasing the importance of the agency’s discretionary interpretation. 

The OCC has not abandoned the prohibition or established a general safe harbor for rewards programs. It has instead deferred the development of more specific standards until it has accumulated experience through supervision and enforcement. Whether that sequence produces a more adaptable framework or prolongs uncertainty remains to be seen. 

Reserve Requirements: Flexibility Within Statutory Limits 

The GENIUS Act specifies the principal categories of eligible reserve assets and requires at least one-to-one backing of outstanding payment stablecoins. Congress therefore made the fundamental policy choice about eligible assets; the OCC’s discretion instead concerns the implementation of liquidity, diversification, concentration, and risk-management requirements. 

The proposed rule offered two approaches to diversification and concentration: a principles-based standard with an optional quantitative safe harbor, or quantitative requirements for all issuers. The final rule adopts a principles-based approach supplemented by two quantitative requirements. Issuers generally must maintain at least 5 percent of reserve assets in specified funds available on demand, while exposure to a single counterparty is generally limited to 40 percent of reserve assets, subject to specified exclusions and exceptions. The rule omits the proposed weekly liquidity requirement, weighted-average maturity limit, and separate quantitative safe-harbor limits on concentration at individual financial institutions. It also strengthens requirements for monetizing reserves under stress, including stress testing and, where necessary, reserve buffers above outstanding issuance value. 

The OCC has not abandoned quantitative reserve regulation; it has narrowed its use while placing greater weight on issuers’ ability to demonstrate adequate diversification, liquidity, and operational resilience. This may allow requirements to reflect differences in business models and risk profiles, rather than impose uniform constraints on every issuer. At the same time, principles-based standards leave more room for supervisory interpretation and may make compliance less predictable. 

The question is whether the OCC has provided sufficient clarity for firms to understand their obligations while retaining the discretion necessary to manage risks that cannot be fully anticipated in advance. The final rule preserves quantitative safeguards, but its reduced reliance on uniform portfolio constraints places greater weight on consistent supervision. 

Is This a Battle Between Banking and Crypto? 

The debate over stablecoin rewards is often presented as a contest between traditional banks and crypto firms. Banks have reason to be concerned that stablecoins offering attractive rewards could compete with deposits, while crypto firms have an interest in developing products that make stablecoins more attractive to consumers and businesses. The consequences could extend beyond individual firms to bank funding, lending, and the allocation of money across the financial system. 

The scale of those effects remains uncertain. It will depend on the adoption of stablecoins, the structure of rewards programs, the location and stability of reserve deposits, and the extent to which stablecoins substitute for existing payment instruments and bank accounts. Stablecoin reserves can also provide funding to banks, so the relationship between stablecoins and traditional banking is not simply one of displacement. The net effect will depend on where reserves are held and whether stablecoins are acquired from existing bank deposits or other assets. 

The policy questions should be distinguished accordingly. Financial stability concerns center on reserve quality, liquidity, redemption, and the possibility of destabilizing outflows. Competition concerns center on whether firms offering economically similar products face comparable risks and regulatory burdens. Protecting bank deposits from competition is a separate objective that should be evaluated on its merits rather than assumed to follow from the need for financial stability. 

The distinction between banking and crypto matters to the extent that competing business models present different risks or operate under different regulatory constraints. It matters less when industry labels substitute for an examination of the economic substance of competing products. The central issue is whether the framework permits competition consistent with financial stability, not whether one industry prevails in a regulatory dispute. 

Congress and the Agencies: Who Makes the Policy? 

The final rule illustrates the limits of congressional legislation that leaves consequential implementation questions unresolved. Congress enacted the GENIUS Act, specified eligible reserve assets, and prohibited certain stablecoin yield payments. It also directed regulators to establish standards for liquidity, diversification, risk management, and other aspects of issuer supervision. The OCC’s task is to translate those statutory requirements into administrable rules, but that task necessarily involves judgements that can affect market structure and competition. 

The yield prohibition is a particularly clear example. Congress established the legal boundary, but the application of that boundary to third-party rewards and commercial arrangements remains uncertain. The OCC proposed a presumption, received objections that it could capture permissible arrangements, and removed it from the final rule. The agency will now develop its understanding through supervision and enforcement before considering further rulemaking. That may be a defensible response to uncertainty, but it leaves the practical scope of the prohibition to be developed over time – and future development and administration to future agencies and administrations. 

Reserve regulation presents a different balance. Congress specified eligible assets and minimum backing, while delegating the development of risk-management standards to regulators. The OCC’s final rule retains quantitative requirements but relies more heavily on principles-based diversification and concentration standards. Here, discretion is not an alternative to statutory direction; it is part of the implementation authority Congress expressly provided. 

The broader question is where implementation ends and policymaking begins. Agencies need discretion to respond to changing markets and unforeseen risks, but extensive reliance on supervision and case-specific interpretation can leave firms uncertain about the rules governing their conduct. Conversely, rigid statutory requirements may become outdated or impose costs that Congress did not anticipate. 

The standard should be practical: Firms should be able to understand the principal factors governing compliance before making consequential business decisions, without requiring the OCC to prescribe the treatment of every possible arrangement. Where the agency’s interpretation determines which business models can compete, it should explain its reasoning and provide meaningful notice of the standards it intends to apply. 

These questions will become more consequential as stablecoins develop and the regulatory framework expands. The OCC has stated that it expects to update its rules and supplement them with guidance as market practices evolve. That approach acknowledges the limits of what can be resolved in a first rulemaking, but it also makes the quality and transparency of future implementation central to the success of the statutory framework. 

Conclusion 

The OCC’s final rule establishes a substantial framework for payment stablecoin issuance, but its most consequential choices increase the discretion retained by the agency. Eliminating the rebuttable presumption leaves the yield prohibition in place while deferring clearer standards for its application; the reserve provisions preserve quantitative safeguards while relying more heavily on principles-based supervision. Neither change necessarily proves that the OCC has sided with banks or crypto firms. If anything, the OCC appears to have sided with itself. Firms should not have to discover the limits of a federal prohibition by guessing what a regulator might decide after the fact. Delegated discretion is not permission to leave consequential policy questions unresolved.
