Stablecoin Reserve Requirements After the GENIUS Act

The Guiding and Establishing National Innovation for U.S. Stablecoins Act (Public Law 119-27), commonly referred to as the GENIUS Act, was signed into law on July 18, 2025. For the first time, federal statute defines what a permitted payment stablecoin issuer is, what assets a stablecoin must be backed by, and how those reserves must be held, segregated, disclosed, and protected. The statute itself is now law. The implementing regulations that translate the statute into day-to-day operating standards are still being written by the Office of the Comptroller of the Currency, the Federal Deposit Insurance Corporation, the Federal Reserve Board, and the Department of the Treasury. The window between enactment and full effective implementation is the period in which issuers, custodians, and reserve administrators are designing the controls they will be examined against.

This post walks through the reserve framework established by Section 4 of the GENIUS Act, the implementing proposals issued by the OCC, FDIC, Federal Reserve, NCUA, Treasury, FinCEN, and OFAC (with some comment windows still open and others already closed), and the operational consequences for any company that issues, distributes, or holds custody of a payment stablecoin in the United States.

Executive Summary

According to Ridgeway Financial Services, the reserve provisions of the GENIUS Act are the centerpiece of the federal stablecoin framework, and the operational lift on issuers will be heavier than the headline one-to-one rule suggests:

  • One-to-one backing is a floor, not a ceiling. Section 4(a)(1) requires reserves at least equal to outstanding stablecoins, but examiners will assess whether the composition, maturity profile, and liquidity tiering of those reserves can actually support redemption demand under stress.
  • The permissible asset list is narrow. Reserves are limited to cash, demand deposits at insured depositories, short-term Treasuries, Treasury-backed repos and reverse repos, qualifying money market funds, similarly liquid federal government assets approved by the primary regulator, and tokenized forms of the foregoing. Corporate paper, longer-duration Treasuries, and crypto collateral are excluded.
  • Rehypothecation is prohibited with narrow exceptions. Reserve assets cannot be pledged, lent, or reused for the issuer’s own purposes. The OCC and FDIC proposals are tightening the exception language so that the prohibition is the operating default and any reuse must be specifically authorized.
  • Monthly disclosure is mandatory and must be examined. Reserve composition reports must be published monthly and examined by a registered public accounting firm. The chief executive officer and chief financial officer of the issuer must personally certify the accuracy of those reports to the primary regulator.
  • Larger issuers face audited financial statements. Issuers with more than $50 billion in consolidated total outstanding issuance must publish annual audited financial statements, audited by a registered public accounting firm in accordance with PCAOB standards, in addition to monthly reserve reports.
  • Stablecoin holders have statutory priority over reserves in insolvency. Section 11 of the Act, codified at 12 U.S.C. § 5910, gives stablecoin holders priority over the issuer and other creditors with respect to required payment stablecoin reserves in any insolvency proceeding, and includes related amendments to Title 11 of the United States Code that elevate holder claims to a high priority position.
  • State and federal paths converge on substance. State-chartered issuers below the $10 billion consolidated outstanding-issuance threshold may operate under a state regime that Treasury determines is substantially similar to the federal framework. Reserve composition is treated as a uniform federal requirement, while capital, liquidity, diversification, and certain prudential standards may be state-calibrated if the state regime is at least as protective as the federal framework.

Why the GENIUS Act Rewrites the Reserve Rulebook

Before the GENIUS Act, stablecoin reserve standards in the United States were a patchwork. New York Department of Financial Services issued the most detailed state-level guidance, applied to issuers operating under a BitLicense or a limited-purpose trust charter. A handful of other states followed with their own regimes, of which California’s Digital Financial Assets Law is the most prominent recent example. Federal banking agencies issued interpretive letters and supervisory guidance but no comprehensive rule. The result was an environment where compliant issuers could meet very different operational standards depending on which charter they held.

The GENIUS Act replaces that patchwork with a single federal floor for any permitted payment stablecoin issuer, whether federally or state regulated. The reserve provisions in Section 4(a) are the most operationally consequential part of the statute. They specify what can sit behind a payment stablecoin, how those assets must be held, what cannot be done with them, and how reserve adequacy must be evidenced to the public, to auditors, and to regulators. Ridgeway Financial Services works with issuers, distributors, custodians, and reserve administrators on the controls and reporting architecture these requirements demand.

The One-to-One Rule and What Actually Counts as Reserves

Section 4(a)(1)(A) requires every permitted payment stablecoin issuer to maintain identifiable reserve assets backing outstanding payment stablecoins on an at least one-to-one basis. The fair value of reserves must equal or exceed the par value of outstanding stablecoins at all times. The OCC’s proposed implementing rule for federal qualified nonbank issuers and the FDIC’s parallel proposal for FDIC-supervised issuers both reinforce this language and add an operational expectation that reserve coverage is measured continuously, not periodically.

“One-to-one” sounds simple, but several operational questions sit underneath it. What is the asset valued at, fair value or amortized cost? How is intraday coverage monitored when the stablecoin trades continuously and the underlying Treasury market does not? What happens if reserves dip below the one-to-one threshold during a redemption wave because permissible assets had to be sold at a loss? Treasury and the federal banking regulators have indicated through proposed rulemaking and comment processes that they expect issuers to maintain operational thresholds above the statutory minimum and to have written escalation procedures triggered when coverage approaches the floor.

Permissible reserve assets

Section 4(a)(1)(A) defines the permissible reserve asset universe. Reserves may consist of:

  • United States coins and currency, including Federal Reserve notes, or money standing to the credit of an account with a Federal Reserve Bank.
  • Funds held as demand deposits (or other deposits withdrawable upon request at any time) or insured shares at an insured depository institution, subject to limitations established by the FDIC and the NCUA to address safety and soundness risks.
  • Treasury bills, notes, or bonds with a remaining maturity of 93 days or less, or issued with a maturity of 93 days or less. This maturity cap is set by the statute itself, not just by implementing rulemaking.
  • Money received under overnight repurchase agreements where the issuer acts as seller, backed by Treasury bills with a maturity of 93 days or less.
  • Overnight reverse repurchase agreements collateralized by Treasury notes, bills, or bonds, subject to overcollateralization in line with standard market terms, that are tri-party, centrally cleared through an SEC-registered clearing agency, or bilateral with a counterparty determined to be adequately creditworthy even in severe market stress.
  • Securities issued by a registered investment company or other registered Government money market fund that invests solely in the assets above.
  • Other similarly liquid federal-government-issued assets approved by the primary federal payment stablecoin regulator (in consultation with the State regulator, if applicable).
  • Tokenized forms of specified reserve assets only: the statute permits tokenized forms of the cash, deposit, Treasury, money market fund, and approved-asset categories above. The overnight repo and reverse repo categories are not eligible for tokenized form under the statute.

The list is exclusive. Anything not on it cannot be a reserve asset. That excludes commercial paper, certificates of deposit beyond insured demand deposit limits, longer-duration Treasuries, corporate bonds, repos backed by anything other than Treasuries, foreign sovereign debt, gold, real estate, and any digital asset other than tokenized forms of the permitted instruments. Issuers that historically held diversified portfolios including commercial paper or short-term corporate notes are restructuring their reserve composition to align with the federal list. The leading issuers have taken visibly different paths on reserve composition within these constraints, and the operational and treasury implications of those choices are covered in our CFO framework for choosing settlement stablecoins.

State-calibrated requirements within the federal floor

Treasury’s proposed framework for determining when a state regime is substantially similar to the federal framework distinguishes between “uniform requirements” and “state-calibrated requirements.” Reserve composition is largely treated as a uniform federal requirement: states may not authorize reserve assets that fall outside the federal list. Capital, liquidity, reserve asset diversification, deposit concentration, and certain prudential standards are state-calibrated, meaning states may design alternative frameworks provided the state regime produces outcomes at least as protective as the federal metrics. For issuers contemplating a state path, the analysis is not whether a state regime is easier than the federal one but whether the state regime has been certified by Treasury as substantially similar under the broad-based principles Treasury proposed in April 2026.

The Rehypothecation Prohibition

Section 4(a)(2) prohibits permitted payment stablecoin issuers from pledging, rehypothecating, or reusing reserve assets, whether directly or indirectly through a custodian or sub-custodian. The OCC’s March 2026 proposed rule reinforces the prohibition and applies it to affiliates of custodians and sub-custodians, closing a structural loophole that might otherwise allow reserve assets to be used as collateral through layered custody arrangements.

Both the OCC and the FDIC have proposed limited exceptions. These cover narrow operational scenarios such as posting collateral to satisfy margin obligations on permitted reverse repurchase agreements that are themselves part of the reserve. The agencies have signaled that the exceptions are intended to be operational accommodations, not commercial flexibility. The FDIC’s preamble language is explicit that issuers are expected to rely on exceptions only as necessary for the enumerated operational purposes and not for any other business purpose.

For operating teams, the practical translation is that the issuer’s treasury function cannot generate yield by lending out reserve Treasuries through securities lending programs, cannot use reserves as collateral for working capital lines, and cannot allow a third-party custodian to use customer assets in its own funding programs. The custody agreements and tri-party arrangements that issuers signed under the pre-GENIUS environment are being rewritten to comply with this prohibition and to provide examiners with a clear documentary trail.

Segregation, Custody, and the No-Commingling Standard

Reserve assets must be segregated from the issuer’s operational funds. The GENIUS Act treats this as a structural requirement that goes beyond bookkeeping. Section 10 of the Act establishes standards for entities providing custodial or safekeeping services for reserve assets, requiring those custodians to be subject to supervision or regulation by a federal banking agency, the SEC, the CFTC, or a state bank supervisor. For an issuer, this means reserve custody cannot be routed through an unregulated entity or held in a wallet structure that comingles reserve assets with operating cash.

Operationally, segregation typically involves: a dedicated set of bank accounts for the cash leg of the reserve at a qualifying insured depository institution, a separate custody arrangement for Treasuries at a qualifying custodian, written policies that prohibit transfers between operating and reserve accounts outside of defined replenishment or reduction transactions, daily reconciliation between the on-chain stablecoin supply and the reserve balance, and an exception protocol for any reconciling item that cannot be cleared within a defined window. Audit-ready issuers maintain a continuous control log that ties on-chain mint and burn events to reserve flows in near real time.

Monthly Reserve Disclosure and the Public Reporting Obligation

Section 4(a)(1)(C) of the GENIUS Act requires every permitted payment stablecoin issuer to publish, on a monthly basis and on the issuer’s public website, the composition of the reserves backing its outstanding payment stablecoins, including the total number of outstanding stablecoins, the amount and composition of reserves by category, and the average tenor and geographic location of custody for each reserve instrument category. Section 4(a)(3) then layers on two distinct obligations: monthly examination by a registered public accounting firm, and personal certification of the monthly report’s accuracy by the issuer’s chief executive officer and chief financial officer to the primary federal payment stablecoin regulator or the state payment stablecoin regulator, as applicable.

The disclosure obligations are concise on the statutory page, but the operational implications are significant. The examination requirement effectively brings an external public accounting firm into the issuer’s monthly close cycle on a permanent basis. The CEO and CFO certification, which is criminally enforceable under the statute by reference to 18 U.S.C. § 1350(c), creates personal accountability comparable to the Sarbanes-Oxley Section 906 criminal certification regime, even though the GENIUS Act is not a securities law. For issuers that have not previously operated under that kind of monthly external assurance discipline, the workflow lift is meaningful. The independent reserve administrator function exists to handle this lift, and Ridgeway Financial Services provides financial reporting and SOX and controls support for issuers building this capability.

What the monthly report must contain

Section 4(a)(1)(C) specifies that the monthly report must include the total number of outstanding payment stablecoins issued by the issuer and the amount and composition of reserves by category, including the average tenor and geographic location of custody of each category of reserve instruments. The OCC and FDIC proposed rules add further specificity on presentation. The expected disclosures in practice include the par value of outstanding stablecoins as of the reporting date, the fair value of each category of reserve asset, the weighted average maturity of Treasury holdings, the names of the depository institutions holding any cash deposits, the names of the custodians holding any Treasury or repo positions, the registered investment companies whose money market fund shares are held in reserve, and a reconciliation showing that the fair value of reserves equals or exceeds the par value of outstanding stablecoins.

The examination by a registered public accounting firm

The statute requires monthly examination by a registered public accounting firm. The form, scope, and assurance level of that examination are subjects of active rulemaking. The OCC’s March 2026 proposal asked for public comment on whether the examination should be conducted at a reasonable assurance level, under AICPA AT-C attestation standards, or under some alternative framework. Final implementing rules may further define the assurance level, criteria, and form of engagement. Until those rules are final, issuers should engage a registered public accounting firm under a scope of work that produces a publishable examination report on the monthly reserve composition and plan for the possibility that the final standard will be elevated.

CEO and CFO certification

Section 4(a)(3) requires the chief executive officer and chief financial officer to submit a certification each month as to the accuracy of the monthly reserve composition report. The statute applies the criminal penalty regime of 18 U.S.C. § 1350(c), the criminal certification penalty provision associated with Sarbanes-Oxley Section 906, to false certifications. The certification obligation is SOX-style in substance, although Section 302, codified at 15 U.S.C. § 7241, is a separate officer-certification and internal-controls framework with its own scope. The CFO is signing not only that reserves equal outstanding par value but that the report fairly represents the composition of those reserves. For an issuer at the early stage of its institutional development, this is the moment at which the controls infrastructure stops being a soft commitment and becomes a personal liability for senior officers. Many issuers are now investing in fractional CFO support specifically to shore up this layer.

Annual Audited Financial Statements for Larger Issuers

Section 4(a)(10) imposes an additional reporting requirement on permitted payment stablecoin issuers with more than $50 billion in consolidated total outstanding issuance that are not already subject to public-company reporting under Section 13(a) or 15(d) of the Securities Exchange Act. These larger issuers must prepare annual financial statements in accordance with generally accepted accounting principles, including related-party transaction disclosures, and must engage a registered public accounting firm to audit those statements in accordance with applicable Public Company Accounting Oversight Board standards, including standards relating to auditor independence, internal controls, and related-party transactions. The audited financial statements must be made publicly available on the issuer’s website and submitted annually to the issuer’s primary federal payment stablecoin regulator.

For an issuer approaching the $50 billion threshold, the planning lift is substantial. A first-time PCAOB-standard audit at this scale typically requires twelve to eighteen months of preparation, including selection and engagement of an audit firm, a readiness assessment, remediation of any internal control deficiencies identified in that assessment, completion of an opening balance sheet reconciliation, and execution of the audit itself. Issuers that wait until they are approaching the threshold to begin this work routinely discover that the timeline is tighter than the statute’s transition windows accommodate.

Statutory Priority Over Reserves in Insolvency

Section 11 of the Act, codified at 12 U.S.C. § 5910, gives stablecoin holders statutory priority with respect to required payment stablecoin reserves in any insolvency proceeding of a permitted payment stablecoin issuer, whether under federal or state law. The claims of stablecoin holders rank, on a ratable basis among themselves, ahead of the claims of the issuer and any other creditor with respect to the required reserves. Section 11 also amends Title 11 of the United States Code, including sections 101, 362, 507, 541, and 1109, to align the Bankruptcy Code with this priority and to ensure that stablecoin holders are treated as claimants for purposes of the priority. The exact mechanics, including whether reserves are categorically excluded from the bankruptcy estate or treated as estate property subject to elevated priority, depend on the interplay of Section 11 with the underlying Bankruptcy Code provisions and will be tested through case law.

This construction has two practical consequences. First, the legal documentation governing the reserve, the custody, and the issuer’s own operations must be drafted to preserve the priority. A reserve held in commingled accounts, or governed by a custody agreement that grants the issuer unrestricted operational access to the assets, may be vulnerable in a bankruptcy court’s analysis. Second, the operational discipline around segregation and the prohibition on rehypothecation are not merely regulatory requirements. They are also the predicate for the statutory protection that gives stablecoin holders a priority claim in distress. An issuer that does not maintain genuine segregation cannot reliably invoke the Section 11 priority.

State and Federal Paths: How the Issuer Categories Interact with Reserves

The GENIUS Act establishes three principal paths to becoming a permitted payment stablecoin issuer. Each path has the same reserve obligations under Section 4 but differs in which agency supervises the issuer and which application process governs entry.

  • Insured depository institution subsidiary. A subsidiary of an insured depository institution may be approved by the appropriate federal banking agency to issue payment stablecoins. The subsidiary structure preserves the parent bank’s existing supervisory relationship and applies the Act’s reserve requirements through the subsidiary.
  • Federal qualified nonbank issuer under the OCC. A nonbank entity may apply to the Office of the Comptroller of the Currency for approval as a federal qualified nonbank payment stablecoin issuer. The OCC supervises the issuer directly, and the OCC’s proposed implementing rule (issued in March 2026) lays out the reserve, capital, liquidity, and operational requirements specific to this path.
  • State qualified issuer under an approved state regime. A state-chartered nonbank entity may operate under a state regime that Treasury has certified as substantially similar to the federal framework, provided the issuer’s consolidated total outstanding issuance remains at or below $10 billion. The state qualified path preserves state oversight as the primary supervisory relationship, but the federal floor on reserves, disclosure, and BSA/AML applies.

An issuer that begins on the state qualified path and grows past $10 billion in consolidated total outstanding issuance must transition within 360 days to federal supervision, either as a federal qualified nonbank under the OCC, as a subsidiary of an insured depository institution under the appropriate federal banking agency, or obtain a waiver from the primary federal regulator. In the alternative, the issuer must cease new issuance until consolidated outstanding issuance falls back below the $10 billion threshold. The threshold is a hard operational trigger, not an aspirational target, and treasury and capital planning at growth-stage issuers should account for it explicitly.

Issuers should also note that Section 5(h) of the Act, codified at 12 U.S.C. § 5904(h), preempts state chartering, licensing, and authorization requirements for Federal qualified payment stablecoin issuers and approved subsidiaries of insured depository institutions or credit unions, in connection with payment-stablecoin issuance. The preemption is specific to this category of issuers and to issuance-related activities. It does not erase all state authority over other licensing questions, does not preempt state consumer protection laws, and does not relieve non-issuance activities (such as broader money transmission, custody for non-reserve purposes, or related services) from separate state law analysis. For background on how the broader money transmitter license framework continues to apply outside the narrow issuer-specific preemption, the MTL pillar covers state-by-state operating regimes for adjacent functions.

The Implementing Rulemakings Still in Motion

The GENIUS Act is law, but the operating details for issuers are being written through implementing rulemakings by the federal banking agencies, the National Credit Union Administration, and the Department of the Treasury (working through both its state-comparability and illicit-finance rulemakings). The most consequential proposals for reserves and related operating standards are:

  • OCC proposed rule (March 2026). Establishes the comprehensive regulatory regime for federal qualified nonbank payment stablecoin issuers supervised by the OCC. The proposal covers reserve composition, reinforces the statutory 93-day maximum maturity for Treasury holdings, the rehypothecation prohibition and its narrow exceptions, two alternative approaches to diversification (a principles-based approach with a quantitative safe harbor at 10 percent daily liquidity and 30 percent weekly liquidity, and a fully principles-based approach), and the contours of the monthly disclosure and CEO/CFO certification process. The OCC also asked for public comment on the appropriate assurance level for the monthly examination.
  • FDIC proposed rule (April 2026). Establishes the parallel framework for FDIC-supervised permitted payment stablecoin issuers and FDIC-supervised custodians. Reinforces the segregation, rehypothecation, and disclosure framework, and addresses deposit insurance coverage for deposits held at insured depository institutions that serve as reserve assets, as well as the treatment of tokenized deposits.
  • Treasury notice of proposed rulemaking on state regime comparability (April 2026). Establishes the broad-based principles Treasury will use to determine whether a state-level regulatory regime is substantially similar to the federal framework. Distinguishes between uniform requirements and state-calibrated requirements and provides Treasury’s view on what level of state divergence is permissible.
  • Treasury and FinCEN proposed rulemaking on illicit finance. Proposed under the authority of Section 4(a)(5) and Sections 7 through 9 of the Act, this rulemaking implements the tailored BSA/AML, sanctions, customer identification, transaction monitoring, suspicious activity reporting, and technical capabilities to block, freeze, and reject transactions that violate federal law. Treatment of foreign payment stablecoin issuers and the foreign-issuer noncompliance designation process are also addressed.
  • Federal Reserve Board rulemaking. Expected to address the standards applicable to depository institution subsidiary issuers and the related supervisory and reporting framework.
  • National Credit Union Administration (NCUA) rulemaking. The NCUA, identified by the statute as a primary federal payment stablecoin regulator for insured credit unions and their subsidiaries, has issued its own proposed rule covering credit union subsidiary issuers and related supervisory expectations.

Comment periods on the proposals are at different stages. The OCC’s comment window closed on May 1, 2026. Treasury’s state-comparability comment period runs through June 2, 2026, and the FDIC’s runs through June 9, 2026. Other proposals have their own comment timelines. The GENIUS Act becomes effective on the earlier of 18 months after enactment (January 18, 2027) or 120 days after final implementing regulations are issued. Issuers should plan for live federal supervision under the new framework in the period following final rules, which means the build-out of controls, custody arrangements, monthly reporting infrastructure, and CEO/CFO certification protocols should be underway now, not deferred until rules are final.

What This Means for Issuers Operationally

The reserve framework translates into a defined set of operating capabilities every permitted payment stablecoin issuer must have in place. The list below summarizes the operational footprint a CFO or controller at an issuer should be building toward.

  • Reserve asset policy. A written policy that defines the permissible asset universe consistent with Section 4(a)(1), maturity limits, concentration limits, diversification targets, and the operating threshold above the statutory one-to-one floor.
  • Custody architecture. Custody agreements with qualifying custodians for each asset class. Cash at qualifying insured depositories. Treasuries at qualifying custodians. Money market fund holdings through registered investment companies. All under agreements that prohibit rehypothecation and provide for daily reporting back to the issuer.
  • Segregation controls. Bank accounts and custody accounts dedicated to reserve operations. Written transfer authorization limits. A controls log that demonstrates segregation has been maintained continuously throughout each reporting period.
  • Daily reserve coverage monitoring. A reconciliation process that compares the on-chain stablecoin supply to the fair value of reserves at least daily, with documented exception handling for any timing differences and an escalation protocol when coverage approaches operating thresholds.
  • Monthly reserve composition reporting. A close process that produces a publication-ready reserve composition report each month, including par value of outstanding stablecoins, fair value by asset category, weighted average maturity for Treasury holdings, custodian and depository institution disclosure, and the reconciliation tying reserves to outstanding issuance.
  • Independent examination engagement. A registered public accounting firm engaged to examine the monthly reserve composition report under a defined scope, with deliverables produced on a schedule that allows monthly publication within the statutory window.
  • CEO and CFO certification process. A sub-certification and review process that supports the personal certification by the chief executive officer and chief financial officer, including evidence packages on reserve composition, internal controls, exception logs, and prior period roll-forward.
  • Redemption policy and disclosure. A publicly disclosed redemption policy meeting Section 4(a)(1)(B): clear and conspicuous procedures for timely redemption of outstanding payment stablecoins, plain-language disclosure of all fees associated with purchasing or redeeming the stablecoins, and at least 7 days’ prior notice to consumers before any change to those fees.
  • Stress scenarios and capital planning. Documented scenarios that test reserve adequacy under redemption waves, interest rate shocks, depeg events, and custodian failure. Capital sufficient to absorb realized losses on permissible reserve sales without breaching the one-to-one floor.
  • BSA/AML program. An anti-money laundering and counter-terrorism financing program meeting the tailored obligations of Section 4(a)(5), including a customer identification program covering account holders, identification and verification for high-value transactions, appropriate enhanced due diligence, transaction monitoring, suspicious activity reporting, sanctions screening, and the technical capabilities to block, freeze, and reject illicit transactions consistent with federal and state law.

How Ridgeway Financial Services Supports Stablecoin Reserve Operations

The reserve framework under the GENIUS Act sits at the intersection of treasury operations, financial reporting, internal controls, and external assurance. Ridgeway Financial Services works with stablecoin issuers, distributors, and reserve administrators on the build-out and ongoing operation of the controls and reporting infrastructure these requirements demand. Typical engagements include:

  • Reserve policy and procedure design aligned to the federal permissible asset list, maturity constraints, and the implementing proposals from the OCC, FDIC, and Treasury.
  • Custody and segregation architecture review covering custody agreements, sub-custody arrangements, account structure, and the documentary trail that supports the Section 11 statutory priority for stablecoin holders.
  • Daily reserve monitoring and exception handling as an outsourced reserve administrator function, with detailed evidence packages for examiner inquiry and for the registered public accounting firm performing the monthly examination.
  • Monthly close and reserve composition reporting with publication-ready output and the supporting workpapers required to substantiate the report.
  • CEO and CFO certification support including the sub-certification framework, evidence files, and review protocols that allow the certifying officers to sign with confidence.
  • Audit readiness for issuers approaching the $50 billion consolidated outstanding-issuance threshold, including opening balance sheet preparation, PCAOB-standard audit readiness, auditor communications, internal control documentation, and related-party transaction support.
  • Fractional CFO and controller support for issuers building the senior finance bench required to operate under the GENIUS Act framework on an ongoing basis.

Ridgeway Financial Services performs these engagements as a non-attest CPA-led advisory firm. The firm does not issue attestation reports under AICPA AT-C standards or audit opinions on reserve adequacy. Issuers engage a separate registered public accounting firm for the monthly examination required by the statute and the annual audit applicable to larger issuers.

Frequently Asked Questions

How is stablecoin reserve coverage measured under Section 4(a)(1)?

Reserve coverage is measured by comparing the fair value of permissible reserve assets to the par value of outstanding payment stablecoins on a continuous basis. Fair value must equal or exceed par value at all times. Examiners are expected to look beyond a single point-in-time snapshot and assess whether the issuer’s controls are designed to monitor coverage intraday and to escalate as coverage approaches the statutory floor.

What assets can a stablecoin issuer hold as reserves?

Section 4(a)(1)(A) limits permissible reserve assets to U.S. coins and currency, Federal Reserve Bank balances, demand deposits or insured shares at insured depository institutions, Treasury bills/notes/bonds with a remaining or issued maturity of 93 days or less (a statutory cap, not just a regulatory proposal), overnight Treasury-backed repos and reverse repos, registered money market funds investing solely in qualifying assets, similarly liquid federal government assets approved by the primary regulator, and tokenized forms of specified categories of those assets (the cash, deposit, Treasury, money market fund, and approved-asset categories, but not the repo or reverse repo categories). Commercial paper, corporate bonds, longer-duration Treasuries, foreign sovereign debt, and digital assets other than tokenized permissible instruments are excluded.

Can a stablecoin issuer earn yield on reserve assets through securities lending?

No. Section 4(a)(2) prohibits issuers from pledging, rehypothecating, or reusing reserve assets directly or indirectly through a custodian. Securities lending programs against reserve Treasuries are not permitted. The OCC and FDIC proposed rules allow narrow operational exceptions, such as posting collateral for permitted Treasury-backed reverse repurchase agreements, but these exceptions are not commercial flexibility.

How often must a stablecoin issuer disclose its reserve composition?

Section 4(a)(1)(C) requires monthly public disclosure of reserve composition on the issuer’s website, including the total number of outstanding stablecoins and the amount and composition of reserves by category, with the average tenor and geographic location of custody. Section 4(a)(3) layers on examination by a registered public accounting firm and personal certification by the chief executive officer and chief financial officer to the primary regulator.

Do reserves need to be audited or only examined?

Section 4(a)(3) requires the monthly reserve composition report to be examined by a registered public accounting firm. The form, scope, and assurance level of that examination are subjects of active rulemaking, and the OCC’s March 2026 proposal asked for public comment on the appropriate standard. Separately, issuers with more than $50 billion in consolidated total outstanding issuance are required by Section 4(a)(10) to publish annual audited financial statements, audited under applicable PCAOB standards.

What happens to reserves if a stablecoin issuer goes bankrupt?

Section 11 of the Act, codified at 12 U.S.C. § 5910, gives stablecoin holders statutory priority over the issuer and other creditors with respect to required payment stablecoin reserves in any insolvency proceeding. Section 11 also amends Title 11 of the United States Code to align the Bankruptcy Code with this priority and to treat stablecoin holders as claimants. The strength of that priority in practice depends on whether genuine segregation of reserve assets has been maintained.

Can a state-chartered issuer hold different reserve assets than a federal qualified issuer?

No. Reserve composition is a uniform federal requirement under Treasury’s proposed framework for determining state regime comparability. States may not authorize reserve assets that fall outside the federal permissible list. States may calibrate certain prudential elements such as capital ratios and diversification thresholds, but the underlying asset universe is the same.

What is the maximum maturity allowed for Treasury holdings in stablecoin reserves?

The statute itself, at Section 4(a)(1)(A)(iii), limits Treasury bills, notes, or bonds held as reserves to a remaining or issued maturity of 93 days or less. The OCC’s March 2026 proposed implementing rule reinforces this cap for federal qualified nonbank issuers, the FDIC’s April 2026 proposal extends it to FDIC-supervised issuers, and Treasury’s framework for state regime comparability carries it through to state qualified issuers. The 93-day cap is part of the statute, not an agency interpretation that could be eased in final rulemaking.
