The accounting world is asking a big question and the answer could change how companies report digital assets forever.
Stablecoins have been quietly doing the work of cash for years. Businesses use them to move money across borders. Crypto companies hold them on their balance sheets. DeFi platforms rely on them as the backbone of daily transactions. But under current U.S. accounting rules, stablecoins are not classified as cash or cash equivalents and that gap between how they function and how they’re reported is becoming harder to ignore.
Now, the Financial Accounting Standards Board (FASB) is taking a closer look.
What FASB Is Examining and Why It Matters
In late 2025, FASB officially added a project to its technical agenda to evaluate whether certain stablecoins should be classified as cash equivalents. This follows the passage of the GENIUS Act in July 2025, the first major federal framework to regulate payment stablecoins in the United States. While the GENIUS Act created rules for how stablecoins must be issued and backed, it did not specify how they should be classified for accounting purposes.
That’s exactly the question FASB is now trying to answer.
Richard Jones, FASB’s chair, put it plainly: “It is just as important to tell people what does not qualify as a cash equivalent as what does.” The board is exploring three possible approaches: revising the existing definition of cash equivalents, creating a new category called “digital cash equivalents,” or adding examples to clarify when stablecoins would, or would not, qualify.
Why Stablecoins Don’t Qualify as Cash (Yet)
Under U.S. GAAP, a cash equivalent must meet a specific definition: it must be a short-term, highly liquid investment that is readily convertible to a known amount of cash with an insignificant risk of value change. Stablecoins, despite being designed to hold a steady value, currently fall short on two key points:
- They are not legal tender. Stablecoins are not issued by a government and are not recognized as official currency under U.S. law.
- They carry issuer risk. A stablecoin’s value depends on the issuer’s ability to maintain its peg and honor redemptions. This introduces counterparty risk that violates the “insignificant risk” requirement.
This creates a real reporting problem. If a company is using stablecoins like cash (for payroll, vendor payments, or treasury management) but can’t report them as cash, the statement of cash flows may not accurately reflect what’s actually happening in the business.
The GENIUS Act Changes the Auditing Game
One thing the GENIUS Act did do is establish clear rules around reserve backing and transparency, and it put auditors front and center. Here’s what stablecoin issuers are now required to do:
- Maintain reserves on a 1:1 basis with outstanding stablecoins, held in high-quality liquid assets like U.S. Treasury bills or Federal Reserve deposits
- Publish monthly reserve reports certified by the CEO and CFO
- Submit to monthly independent examinations by a registered public accounting firm
- Issuers with more than $50 billion in outstanding stablecoins must also undergo full annual financial statement audits
This is a decisive shift from the old world of voluntary attestations. Stablecoin issuers now have legally binding obligations and accounting firms need to be ready to meet them.
Proof of Reserves: The New Standard for Trust
Central to stablecoin auditing is a concept called Proof of Reserves. A Proof of Reserves audit verifies that a stablecoin issuer holds sufficient backing assets to cover all outstanding tokens; this essentially confirms a 1:1 reserve ratio.
It’s worth understanding what this actually involves. During a Proof of Reserves engagement, auditors typically inspect:
- The total circulating supply of the stablecoin on-chain
- Reserve assets held by custodians, including asset type and liquidity
- Redemption terms, custodial arrangements, and any liens or encumbrances
Technically, Proof of Reserves engagements are attestations, not full audits. The scope is limited to the reserves and outstanding tokens, not the company’s entire financial statements. But the rigor applied is the same, and because the scope is narrower, these reports can be published far more frequently, even in real-time, providing ongoing transparency that a once-a-year audit simply can’t.
What This Means for Cryptocurrency Accounting Software
Here’s the challenge most accounting firms face: standard audit tools weren’t built with blockchain in mind. Blockchain explorers tell you what’s on-chain but they don’t give you audit-ready outputs, historical balance queries as of a specific date, or multi-chain coverage in a single workflow.
That’s where cryptocurrency accounting software built specifically for auditors becomes essential. Tools like LedgerLens, built for auditors, by auditors, allow firms to validate balances across 15+ blockchains, run mass address queries at scale, and test core audit assertions like existence, ownership, completeness, accuracy, and valuation, all in one platform.
For smaller and mid-market firms, this kind of crypto audit software is what levels the playing field. Large firms can build proprietary blockchain nodes and internal tools. Everyone else needs purpose-built platforms that make it possible to take on stablecoin attestation engagements, Proof of Reserves work, and financial statement audits involving digital assets, without reinventing the wheel.
The Bottom Line for Auditors and Finance Professionals
The stablecoin accounting question is far from settled. FASB’s review is ongoing, with the GENIUS Act taking full effect in 2027. But the direction is clear: stablecoins are becoming more regulated, more audited, and more integrated into mainstream finance.
For auditors, this means two things. First, demand for Proof of Reserves audit work is accelerating, especially for stablecoin issuers who now have legal obligations to provide monthly attestations. Second, the firms best positioned to capture this work are the ones that invest now in the right cryptocurrency accounting software and build expertise in on-chain audit procedures.
Whether stablecoins eventually earn cash equivalent status under GAAP or get their own new category, one thing is certain: the intersection of crypto and financial reporting is no longer a niche topic. It’s becoming a core competency for the modern accounting firm.
LedgerLens is a crypto audit and attestation platform built for auditors. Whether you’re conducting a financial statement audit with digital assets on the balance sheet or taking on a Proof of Reserves engagement for a stablecoin issuer, LedgerLens gives your firm the tools to get it done.
