A Stablecoin Can Be Fully Reserved and Still Have a Liquidity Problem

A stablecoin can hold enough assets to cover every token in circulation and still fail the moment that matters most: when holders want their dollars back.

Solvency asks whether the value of an issuer's assets is sufficient to meet its liabilities. Liquidity asks whether the issuer can turn those assets into usable cash, through functioning counterparties and payment rails, quickly enough to meet redemption demand. A reserve report can provide evidence for the first question while saying much less about the second.

For stablecoins operating continuously across global markets, that distinction is fundamental. Tokens move onchain around the clock. Banking systems, settlement windows, asset markets, custodians, and operational teams do not always do the same. When redemption demand accelerates, the real test is what the issuer can mobilize, when, through whom, and under what conditions.

In this new world of digital assets, Full reserves are necessary but not sufficient.

The missing dimension in stablecoin due diligence

Stablecoin analysis has understandably focused on reserve sufficiency and reserve quality. Are circulating tokens backed one-for-one? Are the assets cash or short-dated government obligations? Are they segregated, attested to, and protected from creditor claims?

Those remain essential questions. But a static reserve composition is a balance-sheet snapshot. Redemptions are a flow and impact the stability of the asset, market, and user experience.

An issuer may hold high-quality assets and still encounter friction if cash is distributed across institutions, securities must be sold or financed before payments can be made, banking partners impose cutoffs, a payment rail is unavailable, or redemption demand arrives faster than liquidity can be replenished. Concentration can magnify each weakness: an arrangement that depends heavily on one bank, custodian, market venue, or conversion channel may be resilient in ordinary conditions and fragile under stress.

This is why 'fully reserved' should not be treated as a complete risk conclusion. It is one input into a larger assessment of asset quality, convertibility, operational readiness, counterparty concentration, and observable market behavior.

What the New York Fed found

A February 2026 Federal Reserve Bank of New York Staff Report, Stablecoin Disintermediation, adds important empirical evidence to this discussion. The authors link public onchain stablecoin issuance and redemption activity with confidential Fedwire payment data and bank reserve balances. Their central finding is that stablecoin activity can transmit liquidity shocks directly into the banking system.

Following new stablecoin banking partnerships, the researchers estimate that partner banks' interbank payment activity increased by 67 percent. A one-standard-deviation increase in primary-market stablecoin activity corresponded to approximately $280 million in additional Fedwire payments for the average treated bank. Measures of intraday reserve volatility increased materially as well.

The balance-sheet response is equally revealing. Partner banks retained approximately $1.5 billion more in reserves in the subsequent period, while their share of loans declined by 14 percentage points relative to the control group. In effect, banks receiving stablecoin-related deposits had to operate more narrowly, keeping more liquidity available to absorb potential payment outflows rather than treating those deposits like ordinary, stable funding.

The paper is preliminary research, and its anonymized bank-level results should not be generalized mechanically to every issuer or banking arrangement. But it establishes an important principle: stablecoin liquidity risk does not stop at the issuer's balance sheet. It reaches into the banks and payment systems that make issuance and redemption possible.

Why stablecoins are uniquely liquidity intensive

Stablecoins combine the expectations of money with the operating model of a nonbank issuer. Holders expect stable value, rapid transfer, and reliable conversion at par. These expectations can create a mismatch between an always-on digital liability and the practical constraints of the offchain financial system supporting it.

Unlike a fund that can net subscriptions and redemptions at the end of the day, a payment stablecoin may need to process large gross flows throughout the day. Issuance brings cash in. Redemption sends cash out. Even if those flows roughly offset over 24 hours, their timing can produce significant intraday pressure.

Speed itself therefore becomes a risk variable. Faster redemption improves usability and confidence during normal conditions. It also increases the amount of immediately available liquidity that issuers and their banking partners must maintain. A system designed to promise rapid conversion must be measured against rapid, concentrated, and potentially correlated demand.

The market has already seen the distinction

The March 2023 banking crisis offered a visible example. After Silicon Valley Bank failed, Circle disclosed that $3.3 billion of USDC reserves had been held at the bank. Circle stated that USDC remained backed and that it would cover any shortfall, but access to part of the reserve was temporarily uncertain. USDC traded below one dollar before recovering after authorities protected the deposits and banking access normalized. Circle's subsequent update on the reserve risk emphasized the importance of moving cash to transaction banking partners and holding the majority of reserves in short-dated U.S. Treasuries.

The lesson is not that high-quality reserves do not matter. It is that reserve value, reserve availability, and market confidence can diverge, particularly over short but consequential periods. Onchain markets can reprice that uncertainty immediately, well before a monthly attestation or financial statement changes.

Regulation is moving toward redemption, not just backing

The policy direction reflects this broader view. The U.S. GENIUS Act established a federal framework for payment stablecoins and requires one-to-one reserves alongside redemption policies and risk-management obligations. The U.S. Treasury's implementation work is translating that framework into operational requirements.

Internationally, the Financial Stability Board's recommendations call for stablecoin arrangements to guarantee timely redemption at par, maintain effective stabilization mechanisms, disclose their operations and financial condition, implement comprehensive risk management, and prepare recovery and resolution plans.

This is the correct direction. Yet 'timely redemption' cannot be demonstrated solely by publishing a list of reserve assets. It requires evidence about actual redemption performance, liquidity buffers, operational dependencies, stress capacity, and the issuer's ability to continue functioning when one component of the system fails.

What stablecoin integrity monitoring should include

A serious stablecoin risk framework should evaluate at least five connected dimensions:

1. Reserve sufficiency and quality: Are liabilities backed, and how quickly can reserve assets be converted into cash without material loss?

2. Primary-market pressure: Are minting, burning, treasury movements, and net issuance patterns showing unusual or accelerating redemption demand?

3. Market liquidity and confidence: Is the token deviating across venues, are spreads widening, is order-book depth deteriorating, or is liquidity fragmenting across chains?

4. Counterparty and infrastructure concentration: How dependent is the issuer on particular banks, custodians, asset managers, bridges, exchanges, or payment rails?

5. Operational resilience: Can the issuer process redemptions during weekends, outages, bank failures, cyber incidents, or sudden increases in demand?

These factors are dynamic. An issuer can look healthy one week and become materially more exposed the next because reserve composition changes, a bank weakens, a bridge is exploited, holders concentrate, or primary-market flows accelerate. Stablecoin ratings should therefore move with the underlying data rather than remain fixed between periodic reviews.

Onchain data can provide earlier evidence

No public onchain system can see every element of an issuer's liquidity position. Bank balances, Fedwire flows, contractual rights, and internal treasury operations are generally private. The New York Fed researchers could make their bank-level connection because they had access to confidential payment data that market participants do not.

But public data can still reveal important changes in pressure and behavior. Treasury-address activity, mint and burn velocity, the concentration and direction of flows, exchange movements, holder composition, cross-chain fragmentation, secondary-market pricing, liquidity depth, and exposure to risky counterparties can all provide signals before conventional disclosures are updated.

The strongest model combines those public signals with issuer-provided reserve, banking, and operational data. This creates a more complete view: what the issuer says it can redeem, what its infrastructure is designed to support, and what the market is showing in real time.

What Webacy recommends

For issuers, institutions, and regulators, the next step is to move stablecoin oversight from periodic reserve verification toward continuous asset-integrity monitoring.

Separate solvency, liquidity, market, counterparty, and operational risk in every stablecoin assessment.
Measure gross intraday issuance and redemption pressure, not only daily net flows.
Monitor the concentration and health of banking, custody, reserve-management, bridge, and liquidity relationships.
Define quantitative escalation thresholds for peg deviation, redemption velocity, liquidity deterioration, counterparty events, and infrastructure disruption.
Run scenarios for correlated redemptions, weekend stress, banking-partner failure, reserve-asset liquidation, bridge disruption, and loss of a major exchange venue.
Give institutions and automated systems clear policy actions: continue, increase monitoring, reduce exposure, pause activity, or escalate to a human reviewer.
Preserve historical risk progression so reviewers can see whether conditions are improving, deteriorating, or repeatedly approaching a threshold.

At Webacy, we view stablecoin integrity as a living system. Reserve backing remains foundational. It must be evaluated alongside the real-time onchain activity, market structure, counterparties, technical dependencies, and redemption conditions that determine whether backing can perform as promised.

Question more than whether the money exists

As stablecoins become embedded in payments, trading, treasury management, and autonomous financial workflows, the cost of treating liquidity as a secondary issue will increase. A stablecoin used as money must remain dependable precisely when demand for conversion is highest.

We need to start asking: Can the system deliver the backing, at par, on time, under stress?
