Stablecoins and Bank Run Risk: What CFOs Need to Know

Stablecoins settle around the clock and move capital across borders in minutes. That efficiency is the point — but it also means that when confidence cracks, outflows happen at software speed rather than banking speed. For firms doing stablecoin accounting, managing treasury in digital assets, or providing audit assurance over crypto-exposed clients, this dual-speed liquidity dynamic is no longer a theoretical concern. It is a balance-sheet risk that regulators on both sides of the Atlantic are actively trying to contain.

Two Clocks, One Balance Sheet

Anthony Vassallo, director of crypto at Silicon Valley Bank (now operating as a division of First Citizens Bank after its March 2023 failure), frames the risk in terms that any CFO will recognise. There are, he argues, two distinct timescales at play.

The slow clock: gradual erosion

The first is a slow-moving structural shift: currency substitution, incremental deposit erosion, and weakening monetary policy transmission that builds over months or years. This is the kind of change that is easy to miss quarter by quarter, even as the cumulative effect becomes significant. For accounting firms serving clients with cross-border payment flows, this is the scenario that tends not to show up as a single journal entry or disclosure event — it shows up as a pattern across many periods.

The fast clock: crisis-speed capital flight

The second timescale is the one that keeps treasurers awake. A depeg event, an issuer shock, or a banking failure can move capital at software speed within hours. The March 2023 episode involving Circle and Silicon Valley Bank illustrated this precisely: Circle disclosed that $3.3 billion of its USDC reserves were held at SVB at the moment of the bank's failure. Within hours, a contained banking event had become a stablecoin crisis, with USDC briefly losing its dollar peg before authorities stepped in to guarantee deposits. The speed of that transmission — from banking failure to stablecoin stress to market-wide repricing — was unlike anything seen in traditional finance.

For firms doing USDC accounting or carrying stablecoin positions on the balance sheet, the March 2023 sequence is a stress-test template, not a historical footnote.

What the Data Shows About Capital Flight

The Bank for International Settlements examined stablecoin flows alongside conventional foreign currency deposits across 130 economies and found that both tend to grow during periods of currency pressure and banking or sovereign stress. Crucially, stablecoin flows appeared less sensitive to capital controls than traditional foreign currency deposits — meaning that the usual policy tools available to a central bank or finance ministry are less effective at containing digital-dollar outflows.

Emerging market dynamics

A report from Sphere Labs and SVB identifies Argentina, Nigeria, and Turkey as markets where stablecoin demand has tracked closely with demand for dollar exposure. In Argentina, 94% of crypto purchased with pesos was in stablecoins. In Turkey, approximately $38 billion in lira was converted into stablecoins over a single year. Arnold Lee, chief executive of Sphere Labs, frames this as fundamentally a dollar-demand story: people in economies with currency pressure are seeking dollar access, and stablecoins provide a route that bypasses traditional banking barriers.

A separate BIS study published in March found that rising demand for dollar-pegged stablecoins can spill into conventional FX markets — putting downward pressure on local currencies and making dollars more expensive to obtain through FX swaps. The effect was stronger when financial intermediaries were already under strain, which is precisely when the underlying fragility is greatest.

The Colombia case

During a January 2025 diplomatic dispute between the US and Colombia, Colombian residents moved funds into digital dollars over a weekend when banks and currency exchanges were closed. The 24/7 availability of stablecoin rails meant that capital could move even when the traditional system was operationally shut. That is a material operational difference from legacy systems, and it has direct implications for how firms model liquidity risk in cross-border treasury operations.

Regulatory Response: MiCA Reserve Requirements and the ESCB Proposal

Regulators are not waiting. Under the current Markets in Crypto-Assets Regulation, stablecoin issuers operating in the EU must hold at least 30% of reserves in bank deposits, rising to up to 60% for significant asset-referenced tokens. The rationale is straightforward: keeping a substantial portion of reserves in the banking system maintains a buffer for redemptions and keeps issuers linked to supervised institutions.

The European System of Central Banks proposal

The European System of Central Banks has now proposed a shift in how reserve requirements are structured — moving toward requirements based on how quickly reserve assets can actually be made available for redemption, rather than simply where they are held. The intent is to prevent a scenario where heavy redemptions force rapid liquidation of assets that cannot settle fast enough to meet the outflow, effectively bleeding commercial lenders dry within a single trading session.

This is a direct response to the liquidity mismatch the European Central Bank has flagged: stablecoins settle 24/7, but many of the reserve assets backing them — including bank deposits and short-dated government securities — are subject to traditional settlement timelines. When redemption demand spikes on a Friday evening or a public holiday, that mismatch becomes acute.

For accounting firms and CFOs advising or auditing stablecoin issuers, the shift toward liquidity-based reserve requirements means that standard reserve disclosures will need to capture not just the composition of reserves, but their effective settlement speed. That is a disclosure and assurance challenge that existing frameworks are only beginning to address. Our earlier analysis of ESMA's MiCA review response on stablecoins and compliance covers the evolving regulatory perimeter in detail.

Stablecoins as Settlement Rail, Not Crypto Position

Not every stablecoin flow represents currency flight or speculative positioning. Pankaj Bengani, co-founder of stablecoin payments company MELD and former executive at Block, reports that close to half of the company's B2B stablecoin offramp volume originates in North America. The businesses using the rails include importers, exporters, technology firms, e-commerce marketplaces, and fintechs.

The fiat conversion pattern

The vast majority of those corporates convert back to fiat immediately after a transaction settles. They are not taking a crypto position. They are using stablecoin infrastructure as a settlement rail instead of SWIFT — capturing the speed and cost advantages of 24/7 settlement without any intention of holding digital assets on the balance sheet.

Bengani's data suggests that supplier payments account for close to a third of business use, with invoice settlement making up roughly a quarter. That pattern looks very different from a retail investor seeking dollar exposure during a currency crisis — but it carries its own accounting implications. If a corporate is routing commercial payments through stablecoin rails and converting immediately, the accounting question is whether the stablecoin ever appears on the balance sheet at all, or whether the transaction can be treated as a direct fiat-to-fiat settlement with a digital intermediate step. The answer will depend on the specific facts, the applicable accounting framework, and whether the firm has adopted ASC 350-60 (for US GAAP entities) or the relevant IFRS treatment.

What is actually being displaced

Bengani's read is that stablecoins are not eliminating banks from the financial system — they are thinning the correspondent banking layer. Reserves still sit in bank deposits and government securities. Businesses still need fiat currencies. Banks remain essential for custody, compliance, liquidity management, and local settlement. What changes is the plumbing: stablecoins may be removing the intermediary steps that existed only because banks historically needed each other to move money across borders, not because those steps added economic value.

That is a more modest displacement than headline risk scenarios suggest, but it is still a structural shift in how cross-border payments are intermediated — and firms need digital asset accounting software capable of capturing these flows accurately, including the point at which a stablecoin is acquired, the duration of any holding period, and the FX rate applied on conversion back to fiat.

Accounting and Audit Implications for Firms

Whether a firm is an issuer, a corporate treasury user, or an audit client with stablecoin exposure, the accounting and assurance challenges cluster around three areas.

Balance sheet classification and measurement

Under US GAAP, ASC 350-60 now requires most crypto assets to be carried at fair value with changes recognised in net income each period. Stablecoins pegged to a fiat currency will typically show minimal fair value movement under normal conditions, but a depeg event — even a brief one — creates a measurement question that needs to be addressed in the period it occurs. Under IFRS, the classification will depend on the contractual terms of the stablecoin and whether it meets the definition of a financial asset, which varies by instrument and issuer structure.

Reserve adequacy and going-concern disclosures for issuers

For auditors providing assurance over stablecoin issuers, the ESCB's move toward liquidity-based reserve requirements will eventually feed into what constitutes an adequate reserve disclosure. Until standards catch up, auditors will need to apply professional judgement about whether a reserve composition that is technically compliant with current MiCA thresholds adequately represents the liquidity risk profile — particularly if a significant proportion of reserves are held in assets with T+1 or T+2 settlement cycles.

AML and transaction monitoring for corporate users

Firms using stablecoin rails for commercial payments need robust crypto bookkeeping software that captures the full transaction lifecycle, including the on-chain address, the counterparty, the timestamp, and the fiat equivalent at the point of conversion. That data is not just a bookkeeping requirement; it is the foundation of any AML monitoring program applied to digital asset flows. The connection between stablecoin payment rails and sanctions risk is well-documented, and firms cannot rely on the speed and convenience of the rail without also managing the compliance obligations that come with it. The broader stablecoin accounting implications of the SEC and CFTC rulemaking push are also relevant context for US-registered firms and their advisers.

Practical Steps for CFOs and Accounting Firms

The regulatory and market dynamics described above translate into a short list of concrete actions for finance teams and their advisers.

Stress-test both clocks

Treasury teams holding or transacting in stablecoins should model both the slow-clock scenario (gradual deposit erosion and reserve yield compression) and the fast-clock scenario (a depeg or issuer shock requiring same-day liquidity). The March 2023 USDC episode provides a useful calibration point for the fast-clock model.

Review reserve disclosure against emerging liquidity standards

Issuers and their auditors should begin aligning reserve disclosures with the direction of travel in the ESCB proposal, even before it becomes binding. Disclosing reserve composition without settlement-speed context will increasingly look incomplete as the regulatory framework evolves.

Establish a clear accounting policy for stablecoin-as-rail transactions

Corporates using stablecoin infrastructure purely as a settlement rail — converting immediately to fiat — need a documented accounting policy that addresses recognition, measurement, and derecognition. If the stablecoin is on the balance sheet for even a short period, the fair value measurement and any foreign exchange treatment must be captured consistently across periods.

Ensure transaction data is audit-ready

Whether for financial statement purposes or AML obligations, every stablecoin transaction in a corporate payment flow should be captured with on-chain reference, counterparty data, timestamp, and fiat equivalent. Firms that cannot produce this data on request face both audit and regulatory exposure.

Frequently Asked Questions

What is the "liquidity mismatch" that regulators are concerned about with stablecoins?

Stablecoins can be redeemed and transferred 24 hours a day, seven days a week, including weekends and public holidays. The reserve assets backing them — bank deposits, short-dated government securities — settle on traditional banking timelines, often T+1 or T+2. If a large volume of redemptions arrives outside banking hours or during a market stress event, the issuer may not be able to convert reserve assets into cash fast enough to meet the outflow. The European Central Bank and the European System of Central Banks have both flagged this mismatch as a systemic risk.

How should a corporate treasury account for a stablecoin used purely as a payment rail?

If the stablecoin is acquired and converted back to fiat within the same transaction or settlement cycle, the firm still needs a documented accounting policy covering recognition, measurement at the point of acquisition, any foreign exchange translation, and derecognition on conversion. Under US GAAP ASC 350-60, crypto assets must be measured at fair value. If the holding period is extremely brief and the stablecoin maintains its peg, fair value movement will typically be negligible — but any depeg during the holding window must be captured. Under IFRS, the classification depends on the instrument's contractual terms. Firms should document their policy and apply it consistently.

What do MiCA's reserve requirements mean for EU-based stablecoin issuers and their auditors?

Under current MiCA rules, e-money token issuers must hold at least 30% of reserves in credit institution deposits, rising to 60% for significant asset-referenced tokens. The ESCB has proposed moving toward requirements based on the settlement speed of reserve assets, not just their category. Auditors providing assurance over issuers should already be considering whether reserve disclosures adequately reflect liquidity risk, even under the current framework, and should monitor the ESCB proposal as it progresses toward binding rules.

Does stablecoin capital flight create a foreign exchange accounting issue for corporates?

Potentially, yes. BIS research found that rising demand for dollar-pegged stablecoins can put downward pressure on local currencies and affect FX swap pricing. For a corporate with payables or receivables in a currency experiencing stablecoin-driven pressure, the FX rate used for translation purposes may be affected. Treasury teams in high-inflation or currency-volatile jurisdictions should ensure their FX risk monitoring captures stablecoin-related pressure on local currency pairs, not just traditional market indicators.

What transaction data should firms capture to satisfy both bookkeeping and AML obligations on stablecoin payments?

At a minimum, firms should record the on-chain transaction reference or hash, the sending and receiving wallet addresses, the counterparty identity (where known), the timestamp, the stablecoin amount, the fiat equivalent at the point of acquisition and conversion, and the purpose of the payment. This data supports fair value measurement for accounting purposes, provides the audit trail required for financial statement assurance, and forms the foundation of transaction monitoring under applicable AML frameworks. Firms that cannot produce this data systematically face both audit qualification risk and regulatory exposure.
