Stablecoin reserve audits play a crucial role in verifying that issuers have sufficient assets to back their token supply. These assessments provide clarity on the state of reserves at a specific point in time, but they do not necessarily equate to a full financial-statement audit. The type and scope of such reports often influence the conclusions that can be drawn from them.
Definitions and scope of reserve reports
A stablecoin reserve audit involves an independent review of the issuer’s claims regarding the tokens currently in circulation and the assets held to back them. Depending on the engagement, this process may be described as an audit, examination, or attestation. The procedures and findings depend on regulatory requirements and the report’s defined scope.
The core purpose is to confirm whether eligible reserve assets, such as cash or certain government securities, match or exceed the outstanding stablecoin supply. Under 12 U.S.C. § 5903, U.S. payment stablecoin issuers must keep clearly identifiable reserves at a minimum 1:1 ratio to tokens. Assets counted as eligible reserves must meet stringent criteria, with only specific cash, Treasury securities of short maturity, certain qualified repurchase agreements, or designated money market funds allowed.
Reserve audits do not just report headline totals. They also examine asset composition, reserve eligibility, custody arrangements, and the method used to calculate token liabilities and asset valuations. Ineligible assets cannot be counted toward reserve requirements.
Procedures and regulatory standards
Accountants performing these reviews evaluate issuer management’s statements and evidence, reporting findings according to engagement criteria. The 2025 AICPA Stablecoin Reporting Criteria give a framework for describing supply and reserve backing, and in January 2026 the AICPA updated its guidance to address operational controls like issuance, redemption, and custody across specified periods.
Some jurisdictions add further requirements. New York’s Department of Financial Services demands monthly CPA examinations for covered dollar-backed stablecoins. This approach tests management’s claims both at the end of the period and on a randomly selected business day, reviewing reserve value by category, the number of tokens, full reserve coverage, and adherence to all conditions.
Reports may provide a snapshot rather than continuous verification, so it is important for readers to examine the date, details on eligible assets, and any qualifications in the accountant’s comments.
Not every aspect of an issuer’s operations typically falls within a reserve report’s scope. Usually, only specified assertions—such as the value and custody of reserves—are examined, leaving other areas outside the report’s conclusions.
Limits of attestations and frequency of checks
An attestation or reserve examination is not interchangeable with a general financial audit. For example, Circle states that Deloitte examines particular management assertions about USDC reserves and issues monthly reserve attestation reports, separate from its role conducting financial statement audits for Circle. U.S. law also distinguishes between monthly reserve reviews and required annual financial-statement audits for issuers with more than $50 billion in consolidated outstanding issuance.
Monthly reserve reports provide only a dated snapshot. Reserve balances and token supply can change rapidly after the measurement date. Under new federal requirements, supervised stablecoin issuers must publish monthly composition reports and accompanying accountant’s exams by noon on the last day of each month, reflecting reserves as of the preceding month’s closing day. This OCC rule is set to take effect on January 18, 2027.
The GENIUS Act will further require issuers to disclose reserve composition details, including average maturity, asset categories, and the custody location for each reserve component. All reserves must be segregated from other assets and held by the issuer or a qualifying institution.
Despite these controls, neither a reserve report nor an attestation can guarantee instant redemption for all holders or eliminate all operational, custody, or regulatory risks. Stablecoins may diverge from their intended price peg, and unexamined aspects of the issuer’s operations remain a potential risk.
The value of a reserve audit depends on its scope and the timeliness of information provided, as older reports may not reflect current backing or changes in reserve composition.
