OCC Finalises GENIUS Act Stablecoin Rule: Effective January 2027

The Office of the Comptroller of the Currency has become the first US federal regulator to publish a final rule under the GENIUS Act, the stablecoin legislation signed into law by President Trump. Issued on 21 October 2026 and set to take effect on 18 January 2027, the rule creates a binding federal framework for payment stablecoin issuance and custody. For accounting firms, CFOs, and auditors with clients holding or issuing stablecoins, the rule is not background noise: it defines the legal and economic characteristics that drive stablecoin accounting treatment under both US GAAP and, for dual-reporting entities, IFRS.

What the GENIUS Act Actually Requires

Before examining the OCC's specific rule, it helps to recall what the statute itself mandates. The GENIUS Act established the first comprehensive federal framework for payment stablecoins in the United States. Its core requirements include:

Statutory foundations

• Full backing: Payment stablecoins must be backed one-for-one by US dollars or equivalently liquid assets at all times.
• Redemption rights: Holders must have a legally enforceable right to redeem at par on demand.
• Annual audits: Issuers are subject to mandatory annual audits of their reserve holdings.
• Interest prohibition: Issuers are prohibited from directly paying interest on stablecoins to holders.

These four pillars are not aspirational guidance. They are statutory requirements that now carry regulatory teeth through the OCC's final rule. Understanding them is the starting point for any stablecoin accounting analysis. For a broader look at how this legislation fits into the wider restructuring of US crypto oversight, see our earlier coverage of how the GENIUS Act reshaped the US regulatory landscape for digital assets.

What the OCC's Final Rule Adds

Comptroller Jonathan Gould described the rule as providing "a clear, practical framework for payment stablecoin innovation, with strong standards for reserve backing, redemption, and risk management." Three structural elements deserve particular attention from accounting professionals.

Pathways for bank and non-bank issuers

The rule creates distinct regulatory pathways for two categories of permitted stablecoin issuers. Banks supervised by the OCC can engage in payment stablecoin activities within their existing charter, subject to the new standards. Non-bank companies gain a separate pathway, giving them a defined route to issuance that did not exist under prior piecemeal guidance. Both categories must meet the same reserve, redemption, and risk management standards: the distinction is supervisory structure, not substantive obligation.

For accounting teams, this matters because the issuer's regulatory status affects how the stablecoin is treated on the issuer's own books. An OCC-supervised bank issuing a payment stablecoin will record the outstanding circulation as a liability, with the reserve assets on the asset side. The quality and liquidity profile of those reserve assets, now federally prescribed, determines both the balance-sheet presentation and the audit procedures required to substantiate it.

Cross-border issuer standards

The final rule extends its reach to stablecoin issuers operating outside the United States but serving US markets or US persons. This extraterritorial scope aligns with the GENIUS Act's intent to prevent regulatory arbitrage, where offshore issuers could otherwise avoid the reserve and audit requirements that apply to domestic entities. For auditors working with multinational clients, this creates a new due-diligence question: does the stablecoin your client holds originate from an OCC-compliant issuer, a MiCA-compliant issuer, or an entity that now falls under OCC jurisdiction regardless of its domicile?

The parallel international dimension is worth tracking. The European Banking Authority has separately designated USDC as a significant e-money token under MiCA, as covered in our analysis of EBA's designation of USDC as a significant e-money token under MiCA. Dual-jurisdiction entities holding USDC now sit at the intersection of both frameworks simultaneously.

Custody standards

The rule also sets standards for custodying stablecoin reserve assets. This is directly relevant to the audit trail: reserves must be held in a manner that supports the one-for-one backing requirement and can be verified in an annual audit. The rule does not specify a single custody model, but it requires that custody arrangements meet standards the OCC considers consistent with the statutory backing requirement. Firms advising issuers on reserve management will need to map their clients' custody structures against those standards before the January 2027 effective date.

The Stablecoin Rewards Reversal: Why It Matters

The most significant departure from the proposed rule is the treatment of stablecoin reward arrangements, and it carries real accounting and regulatory implications.

What changed between the proposed and final rule

The OCC's proposed rule had included a presumption that certain arrangements between stablecoin issuers and third parties, specifically those that allow users to earn rewards on their stablecoin holdings, could be unlawful. That presumption suggested that issuers might be indirectly circumventing the statutory interest ban by routing yield payments through third-party platforms rather than paying interest directly.

The final rule removes that presumption entirely. A regulatory official confirmed on a press call that the proposed language was based on an assessment of whether evasion was likely, not a conclusion that a "nascent market" for these arrangements actually constituted evasion. In other words, the OCC stepped back from pre-emptively labelling third-party reward structures as illegal, while explicitly preserving its authority to pursue genuine evasion if and when it sees it.

The enforcement carve-out that remains

The removal of the presumption is not a green light for issuers to pay yield through intermediaries without restriction. The OCC was explicit: "To the extent that issuers have relationships with third parties, we would seek to ensure that those relationships do not violate the statutory prohibition, and we do have authority to enforce against evasions of the act. And if we see a clear evasion, then we could pursue it accordingly."

This matters for accounting teams in a specific way. If a client's stablecoin holding generates rewards through a third-party arrangement, the economic substance of that arrangement must be assessed. Is the reward a return of principal, a yield, a loyalty payment, or something else? The answer determines both the income recognition treatment and whether the arrangement raises a compliance flag under the GENIUS Act's interest prohibition.

The broader political context

The stablecoin rewards debate has been one of the most contested issues in US crypto legislation. Banks have argued that allowing rewards on stablecoins creates a deposit substitute that draws funding away from traditional institutions, potentially weakening community banks. The crypto industry has pushed back, contending that rewards are a product feature distinct from deposit interest. The GENIUS Act did not resolve this tension completely; it banned direct interest payments by issuers but left third-party reward arrangements in a grey zone. The OCC's decision to remove the presumption keeps that grey zone open, at least until further guidance or enforcement action narrows it.

Stablecoin Accounting Under US GAAP and IFRS

The OCC rule does not itself prescribe accounting treatment. That remains the domain of the FASB and, for IFRS reporters, the IASB. But the rule's definitions and requirements are likely to influence how standard-setters and preparers approach the classification question.

US GAAP: ASC 350-60 and the fair value election

Under ASC 350-60, the FASB's crypto asset accounting standard that took effect for fiscal years beginning after 15 December 2024, entities measure qualifying crypto assets at fair value with changes recognised in net income. The standard currently applies to fungible digital assets that are not classified as financial instruments under other GAAP guidance.

Payment stablecoins create a classification question. If a stablecoin is deemed to be a financial instrument because it carries a contractual redemption right at par, it may fall outside ASC 350-60 and be accounted for differently, potentially as a cash equivalent or a receivable. The GENIUS Act's mandatory redemption requirement strengthens the argument that payment stablecoins are financial instruments, which would place them outside the fair value crypto asset model. Accounting teams should document their classification rationale now, before the 18 January 2027 effective date creates a regulatory anchor that auditors will reference.

IFRS: IAS 7, IFRS 9, and the IAS 38 question

For entities reporting under IFRS, stablecoin accounting involves a similar classification exercise with different standards. The key questions are whether a payment stablecoin qualifies as cash or a cash equivalent under IAS 7, whether it is a financial asset under IFRS 9, or whether it falls to IAS 38 as an intangible asset when neither of the first two classifications applies.

The GENIUS Act's full-backing and par-redemption requirements tilt the analysis toward IAS 7 or IFRS 9 treatment for payment stablecoins issued under the OCC framework. A stablecoin that is fully backed by liquid assets and redeemable at par on demand has economic characteristics closer to a demand deposit than to a speculative digital asset. That said, IFRS has not issued specific guidance on stablecoins, and preparers must apply judgement. The OCC rule's detailed reserve and redemption requirements will inform that judgement, even if they do not determine it.

Practical Steps for Accounting Firms and CFOs

With the effective date set for 18 January 2027, the window for preparation is defined. The following actions are worth prioritising before year-end.

For accounting and audit firms

• Client inventory: Identify which clients issue, hold, or custodise payment stablecoins. Map each against the OCC's new issuer categories and reserve standards.
• Classification memos: Prepare or update accounting policy documentation covering the GAAP or IFRS classification of each stablecoin position. The OCC rule's par-redemption and full-backing requirements are new inputs for that analysis.
• Audit procedures: For issuer clients, the mandatory annual audit requirement means reserve verification procedures need to be designed or updated. The rule's custody standards define what constitutes a verifiable reserve.
• Rewards arrangements: For clients with stablecoin reward programmes, document the economic substance of the third-party arrangement and assess whether it is consistent with the GENIUS Act's interest prohibition, given the OCC's retained enforcement authority.

For CFOs and finance teams

• Treasury policy: If your treasury policy currently treats stablecoins as cash equivalents, confirm that those stablecoins will be issued by an OCC-compliant or equivalent regulated entity after 18 January 2027. Holdings in non-compliant stablecoins may carry different risk and accounting characteristics.
• Disclosure: Consider whether the OCC rule changes the risk disclosures relevant to stablecoin holdings. Mandatory redemption rights and reserve backing are material facts for investors assessing liquidity risk.
• Cross-border exposure: The rule's extraterritorial reach means that even foreign-issued stablecoins used in US operations may now be subject to OCC standards. Legal and compliance teams should assess whether your stablecoin counterparties are OCC-compliant.

What Comes Next

The OCC is the first agency across the line, but it will not be the last. Other federal regulators are still working through their own GENIUS Act implementation rules. The Federal Reserve, the FDIC, and state-level money transmitter regulators all have roles to play, and their rules may impose additional or different requirements on the same issuers the OCC now regulates.

The broader legislative picture is also incomplete. The CLARITY Act, which was intended to address digital asset market structure more broadly, has stalled in Congress. That means the OCC's stablecoin rule lands in a statutory environment where payment stablecoin regulation is largely settled, but adjacent questions about exchange regulation, DeFi, and commodity versus security classification remain open. Accounting teams should watch for further regulatory developments but can plan with confidence around the GENIUS Act requirements now that the OCC has finalised its implementing rule.

Frequently Asked Questions

When does the OCC's GENIUS Act final rule take effect?

The rule takes effect on 18 January 2027. Entities that issue, hold, or custodise payment stablecoins should use the intervening period to align their reserve structures, custody arrangements, and accounting policies with the new requirements.

Does the OCC rule change how stablecoins are classified under US GAAP?

The rule does not directly prescribe GAAP treatment; that remains the FASB's domain. However, the statutory requirements for full backing and par-on-demand redemption, which the rule enforces, are relevant inputs when determining whether a payment stablecoin is a financial instrument under existing GAAP guidance or falls within the scope of ASC 350-60.

Are stablecoin rewards now permitted under the GENIUS Act?

The GENIUS Act prohibits issuers from directly paying interest on stablecoins. The OCC's final rule removed a proposed presumption that third-party reward arrangements are unlawful, but the OCC explicitly retained authority to pursue enforcement where it identifies genuine evasion of the statutory prohibition. The legal risk around reward structures has not been eliminated, only the blanket presumption of unlawfulness.

Does the rule apply to foreign stablecoin issuers serving US markets?

Yes. The final rule sets standards for stablecoin issuers outside the United States that operate in US markets or serve US persons. This extraterritorial scope is designed to prevent offshore issuers from avoiding the GENIUS Act's reserve and audit requirements through jurisdictional arbitrage.

What does the mandatory annual audit requirement mean for auditors?

Stablecoin issuers subject to the OCC rule must undergo mandatory annual audits of their reserve holdings. For accounting firms, this creates a defined engagement scope: auditors need procedures to verify that reserves are held in qualifying liquid assets, that custody arrangements meet OCC standards, and that the one-for-one backing is maintained continuously. Firms with issuer clients should begin scoping those procedures now.
