USDC Deep Dive: Why Monthly Attestations Don't Eliminate Reserve Risk — And What Traders Need to Know

The Core Claim: Attestation Is Not Audit

A monthly attestation is a point-in-time procedure. What it is not: a continuous, real-time, or even daily examination of reserve composition, counterparty credit quality, or liquidity profile. The distinction is structural, not semantic, and it has direct consequences for any trader who holds USDC as margin collateral or a base currency.

A continuous audit, the standard traders implicitly assume when they describe USDC as 'transparent', would require ongoing verification of every asset in the reserve pool, its custodian health, and its liquidation value under stress. No stablecoin issuer currently provides this.

USDC's attestation framework is more rigorous than many competitors, but rigor within a monthly cycle is not equivalent to rigor across every day of that cycle.

The 30-Day Blind Spot

The issuer may rotate from one set of short-duration instruments or counterparties to another, alter the proportion held at specific custodians, or accumulate concentration in a single institution, and none of these shifts are visible to the market until the next report, if at all.

The 30-day attestation window is therefore a structural blind spot: the snapshot confirms what existed on the observation date, not what exists today.

This is not a theoretical concern. The March 2023 banking stress demonstrated that a reserve counterparty failure can move from invisible to acute within days, well inside a single attestation cycle. USDC's depeg during that episode was not preceded by any mid-cycle disclosure.

The episode is the clearest historical illustration of the gap this article examines: the attestation was clean; the risk materialized anyway.

Quantifying the Transparency Premium, and Its Limits

Markets have historically priced USDC at a smaller discount to par than competing stablecoins during stress events, implying traders assign it a transparency premium, a willingness to hold USDC at a price above what they would pay for less-documented alternatives, because they believe the reserve evidence is stronger.

The analytical question is whether that premium is fully justified given attestation lag. Consider what the premium actually compensates for: it reflects the probability that reserves are sound multiplied by the confidence that any unsoundness would be detected and disclosed quickly.

Monthly attestations strengthen the first term but do so only at 30-day intervals, leaving the second term, detection speed, materially weaker than a continuous audit would provide.

The gap between perceived and actual transparency is therefore not zero. It is measurable in time, approximately 30 days at maximum, and in counterparty risk, since the identity and health of individual reserve custodians is not updated daily.

Why This Matters More for Leveraged Traders

For a spot holder, a temporary USDC depeg is an unrealized mark-to-market loss that may recover. For a leveraged trader using USDC as margin collateral, the same depeg is an immediate reduction in usable collateral, and that reduction can be enough to trigger liquidation before the underlying position has moved at all.

Consider a concrete illustration:

The mechanism is direct: if your margin asset reprices downward, your effective collateral balance falls without your underlying trade moving a single tick. At elevated leverage, where liquidation distances are measured in fractions of a percent, a collateral-asset depeg of even a few cents can close the gap between a viable position and a forced liquidation.

This asymmetry makes stablecoin selection a genuine risk-management decision, not merely a preference.

Traders using stablecoins as margin should treat the attestation lag as part of their position risk, not a background condition.

The Asymmetry of Attestation Timing

What it cannot provide is assurance about the following 29 days. A reserve counterparty failure, a shift in custodian concentration, or a liquidity deterioration in the underlying instruments could occur the morning after publication with no mandatory disclosure mechanism triggering before the next scheduled attestation.

This is not an argument that USDC is unsafe.

It is an argument that the gap between what 'monthly attestations' actually verify and what traders assume they verify is a measurable, manageable risk, one that should be priced into position sizing, hedged against through collateral diversification, and tracked through supplementary sources like on-chain reserve wallet flows and secondary market discount data.

Framing the Rest of This Article

The thesis here is narrow: USDC's transparency advantage over less-documented stablecoins is real but smaller than the transparency premium its market pricing implies.

The monthly attestation cycle creates a 30-day window in which reserve composition, counterparty health, and liquidity profile can shift without mandatory public disclosure. For spot holders, this is a background risk.

For leveraged traders using USDC as margin, it is an active position risk that operates independently of the underlying trade.

The sections that follow examine the mechanics of reserve composition reporting, the historical behavior of the USDC/USD peg across stress events, practical hedging approaches for collateral risk, and how the emerging stablecoin regulatory framework may alter attestation frequency and disclosure requirements.

The goal throughout is to replace a binary 'safe or unsafe' framing with a more precise one: USDC carries a quantifiable, time-bounded transparency risk that disciplined traders can measure and manage.

Each token is backed by reserve assets held outside the blockchain, with the intent that one USDC can always be redeemed for exactly one dollar. Understanding how that backing is structured, and where its limits lie, is the foundation for evaluating USDC as a margin asset or settlement medium.

Origin and Governance Structure

Issuance and Redemption Mechanics

The issuance process is straightforward in design. This mint-and-burn loop is what makes USDC a fully-reserved stablecoin rather than an algorithmic or fractionally-backed one.

The mechanism works as long as three conditions hold simultaneously: the reserves are liquid (convertible to cash quickly), accessible (not frozen by a custodian or counterparty), and sufficient (equal to or greater than tokens in circulation). Each condition is independent. A reserve asset can be liquid in normal markets but inaccessible if the custodying bank suspends withdrawals.

It can be accessible but insufficient if a counterparty defaults on obligations. The March 2023 Silicon Valley Bank episode demonstrated that the accessibility condition can fail within a single weekend, faster than any monthly attestation cycle can detect or disclose.

Reserve Composition

The reserve structure has evolved over time toward a more conservative profile. The dominant component is short-duration US Treasury bills, held in segregated accounts through a dedicated government money market fund structure.

This T-bill allocation is designed to minimize credit risk and maximize liquidity: Treasury bills trade in deep markets and can be converted to cash within the settlement cycle of the securities themselves.

The secondary component, and the one most relevant to counterparty risk, is cash deposits held at banking counterparties. These deposits are not segregated in the same way as the T-bill holdings; they sit on the balance sheets of the banks that hold them.

If a bank fails or suspends withdrawals, the cash component of the reserve becomes temporarily inaccessible even if it is ultimately recoverable through deposit insurance or receivership proceedings. The SVB episode placed roughly a portion of USDC reserves in this category, producing the depeg event that followed.

The specific percentage split between T-bills and cash deposits has shifted across reserve reporting periods.

Attestation Workflow

The process involves Deloitte confirming, as of a specific month-end date, that the value of reserve assets equals or exceeds the number of USDC tokens in circulation at that moment. This is a point-in-time confirmation, not a continuous review.

What Deloitte does not do: monitor reserve composition between attestation dates, verify counterparty creditworthiness on an ongoing basis, assess liquidity under stress scenarios, or flag changes that occur after the month-end cutoff.

The attestation report's formal language is precise about this scope, but the distinction is often lost in market commentary that describes USDC as "fully audited" or "continuously verified." Neither characterization is accurate.

Key Terms Compared

The vocabulary around stablecoin transparency is frequently misused. The table below defines the four terms that matter most for evaluating reserve quality:

The dashboard updates more frequently than the Deloitte reports but does not carry the same third-party verification and does not disclose granular counterparty-level exposure.

USDC vs. USDT Reserve Structure

Tether (USDT) and USDC represent two different approaches to reserve transparency, and the contrast is instructive.

Tether's reserve history has included a broader and more opaque mix of assets: commercial paper, secured loans, other investments, and cash equivalents alongside Treasury bills. Tether has faced regulatory scrutiny and enforcement actions related to reserve misrepresentation in prior years.

Its attestation history is less consistent and has been performed by smaller accounting firms rather than a Big Four firm. The composition of Tether's reserves has improved toward higher-quality assets over time, but the historical record created a persistent credibility discount.

USDC's reserve approach, T-bill-heavy, Big Four attested, with regular public reporting, is structurally more conservative. But "more conservative" does not mean risk-free. The SVB episode showed that even a T-bill-dominant reserve structure carries banking counterparty exposure in its cash component, and that exposure can crystallize faster than attestation cycles reveal.

The practical consequence for traders: USDC has historically traded closer to par than USDT during market stress events, reflecting the market's assessment of its higher reserve quality. Whether that premium is fully justified, given the attestation timing gap, is the central question this article examines.

Multi-Chain Issuance and Bridge Risk

For a trader holding USDC as margin:

• -Wrapped or bridged USDC equivalents on non-native chains carry that reserve risk plus the bridge's smart contract risk.

The distinction matters when evaluating margin asset quality.

The Attestation Gap Made Visible: Silicon Valley Bank, March 2023

The March 2023 SVB collapse is the clearest empirical test the stablecoin market has produced of what happens when a reserve counterparty fails inside an attestation cycle. It exposed something more structurally uncomfortable: that a clean, professionally attested reserve report can become materially misleading within weeks, with no disclosure mechanism to signal the deterioration in real time.

The Timeline: Clean Attestation, Then Silence Until Crisis

The last attestation published before SVB's seizure confirmed that reserves were intact as of that reporting date. What it could not capture, and was not designed to capture, was the ongoing concentration of cash deposits at Silicon Valley Bank in the weeks that followed.

That figure became public knowledge only after the seizure, not before it. Between the prior attestation's month-end cutoff and March 10, there was no mid-cycle disclosure obligation triggered, no mandatory reserve update, and no public filing that would have allowed a market participant to observe the concentration risk building in real time.

The attestation framework, operating exactly as designed, produced a gap between reported reality and actual risk.

USDC Price Action: The Depeg and Its Velocity

Markets responded immediately. Curve's 3pool, which holds USDC, USDT, and DAI in roughly equal weights under normal conditions, became severely imbalanced as participants rotated out of USDC and into USDT and DAI.

At the trough, USDC's share of the pool swelled disproportionately, a mechanical consequence of one-sided selling pressure that any Curve liquidity provider with USDC exposure absorbed directly.

The spread between USDC and USDT at the trough, two assets nominally priced at $1.00, reflected the market's real-time assessment of unquantified regulatory and insolvency risk. USDT, despite its historically more opaque reserve disclosures and a longer history of reserve composition controversy, held closer to par through the SVB weekend.

That outcome complicates the standard narrative that USDC's transparency advantage translates into greater crisis-period stability.

Why the Peg Recovered, and What That Reveals

The $3.3 billion was recoverable because the federal government intervened.

This is the critical structural lesson the SVB episode offers. A different regulatory posture, one in which uninsured depositors took a haircut, would have produced a permanently impaired reserve and a stablecoin that could not honor 1:1 redemption without restructuring.

Contagion: DAI, Curve 3pool, and DeFi Base Assets

The depeg did not remain contained to direct USDC holders. DAI, which used USDC as a significant component of its collateral backing through the Peg Stability Module, was exposed to USDC's price movement.

A stablecoin collateralized partly by another stablecoin that has depegged faces a recursive problem: as USDC fell, the collateral value supporting DAI declined, creating secondary peg pressure on DAI itself. DAI traded below par during the weekend, though less severely than USDC.

Protocols that used USDC as a base asset for lending markets, liquidity pools, or yield products experienced knock-on stress. Borrowers whose collateral included USDC saw collateral values compress. Lending protocols faced the question of whether to mark USDC at market (below $1.00) or at par, a discretionary decision with significant liquidation implications.

The Curve 3pool imbalance meant that any protocol pricing assets through Curve oracles was receiving price feeds reflecting the stressed pool composition, not an orderly market.

USDC's deep integration as a base asset across DeFi meant that a reserve counterparty failure at one bank could generate liquidation pressure, oracle distortions, and pool imbalances across dozens of protocols simultaneously.

The attestation had confirmed reserves were intact as of the prior month-end. Between that date and March 10, the risk was invisible to the public.

It is an observation about the structural limits of a monthly attestation regime: the framework is designed to confirm a snapshot, not to surveil ongoing counterparty health. But high transparency within a monthly snapshot framework still produces a 30-day blind spot, and that blind spot was the precise mechanism through which the SVB risk accumulated without market-visible warning.

The Trader's Practical Window: 48–72 Hours of Maximum Exposure

For a trader holding USDC as margin collateral, or running a DeFi position denominated in USDC, the SVB episode defines the realistic worst-case duration of a depeg event driven by reserve counterparty failure. During that window, USDC traded near $0.87, Curve pools were severely imbalanced, and DAI faced secondary stress.

No real-time reserve monitoring tool available to a retail or even institutional trader would have identified the SVB concentration risk before March 10. The attestation had cleared the prior month-end. There was no public disclosure of the deposit concentration at any point before the seizure.

The practical implication: a leveraged position using USDC as margin must be sized and stop-managed against the possibility of a 10-to-15 cent collateral shock that can materialize over a single weekend, persist for 48-to-72 hours, and resolve only if a government backstop is forthcoming.

That is not a scenario that attestation frequency improvements alone can eliminate, because the gap between clean attestation and reserve deterioration can close faster than any monthly reporting cycle. Traders who treat stablecoin attestations as continuous audits, rather than point-in-time confirmations, are mispricing the residual risk in their margin stack.

The SVB weekend is the empirical proof of how quickly that mispricing can become a liquidation event.

The GENIUS Act: What US Federal Stablecoin Legislation Actually Mandates

The GENIUS Act (Guiding and Establishing National Innovation for US Stablecoins) represents the most substantive US federal stablecoin legislation to advance through Congress in the 2025–2026 period.

The Act's core provisions cluster around four areas. First, reserve asset requirements: issuers must hold reserves exclusively in high-quality liquid assets, primarily short-duration US Treasury instruments and insured bank deposits, a standard USDC's existing T-bill-heavy reserve composition largely satisfies.

Second, 1:1 backing mandates: every dollar of circulating stablecoin must be matched by a dollar of qualifying reserve assets, confirmed periodically. Third, redemption rights: holders must have a legally enforceable claim to redeem at par, removing ambiguity about whether a stablecoin is a deposit, a security, or a prepaid instrument.

Fourth, licensing pathways: the Act creates a federal licensing track through the Office of the Comptroller of the Currency alongside state-chartered pathways, allowing issuers to choose a regulatory domicile rather than operating in a legal grey zone.

The practical effect: USDC already meets or approaches the core reserve and redemption criteria the GENIUS Act codifies, so compliance costs are lower relative to issuers who would need to restructure reserves materially.

What the GENIUS Act Does Not Change: Attestation Frequency

Here is the critical qualification. The GENIUS Act, as structured through the 2025–2026 legislative process, mandates periodic reserve reporting, not continuous reserve monitoring, and not intra-month disclosure obligations. The reporting cadence contemplated by the legislation does not require real-time or even weekly reserve verification.

This means the structural timing gap described earlier in this article, the 30-day window between attestation snapshots during which reserve composition can shift without any public disclosure obligation, is not closed by federal stablecoin regulation.

Legislation can require that attestations occur, specify which assets qualify as reserves, and mandate that those attestations be provided to regulators. It cannot require that a bank counterparty remain solvent between reporting dates.

The distinction is precise and consequential: reserve-disclosure regulation governs issuers, not the gap between snapshots. A regulator reviewing USDC's compliance file would see a clean attestation as of month-end. A reserve counterparty failure occurring on day 15 of the following cycle would not trigger any mandatory mid-cycle disclosure under the framework the GENIUS Act establishes.

That structural blind spot persists regardless of how rigorous the attestation standard becomes.

MiCA: USDC as an E-Money Token in the EU

The Markets in Crypto-Assets Regulation (MiCA) introduces a parallel but distinct compliance layer for USDC operating in European markets. Under MiCA's classification framework, USDC qualifies as an e-money token (EMT), a category reserved for asset-referenced tokens pegged to a single fiat currency.

This classification carries specific obligations that, in some respects, exceed what the GENIUS Act currently specifies.

The Irish entity structure means USDC issued or redeemed within EU markets is subject to ongoing Central Bank of Ireland supervision, not merely periodic attestation.

MiCA's reserve requirements for EMTs include reserve segregation, reserves must be held separately from the issuer's operational assets and must remain protected in the event of issuer insolvency. This is structurally more explicit than US requirements on the same point.

MiCA also imposes transaction volume limits on non-euro EMTs used as a means of payment, a provision that could constrain USDC's role in EU payment rails if volumes grow materially.

The comparison between MiCA and the GENIUS Act reveals a divergence in regulatory philosophy. MiCA focuses on ongoing supervisory oversight and reserve segregation standards, with a licensed entity permanently accountable to a national regulator. The GENIUS Act focuses more on reserve asset quality and federal licensing eligibility.

Neither framework addresses intra-cycle counterparty risk, the specific vulnerability the SVB episode exposed.

The Competitive Regulatory Gap: USDC vs. USDT and Emerging Bank Stablecoins

Regulatory positioning now functions as a meaningful market structure variable, not merely a compliance footnote. The divergence between USDC and Tether (USDT) on this dimension is substantial. Tether operates primarily from non-EU jurisdictions and has not sought licensing under MiCA's EMT framework, which means USDT faces distribution constraints in regulated EU markets.

As MiCA enforcement has progressed through 2025–2026, the practical result is that compliant EU platforms face limitations on offering USDT as a primary settlement asset, a structural tailwind for USDC in that geography.

PYUSD (PayPal USD) occupies a different regulatory position. Backed by PayPal's banking relationships and issued under US money transmitter licenses, PYUSD benefits from PayPal's existing regulatory infrastructure but lacks the breadth of institutional DeFi and CeFi integrations USDC has accumulated.

PYUSD's reserve composition is also weighted toward short-duration Treasuries and bank deposits, similar in structure to USDC, meaning neither has resolved the attestation-gap problem the other has.

The emerging category of bank-issued stablecoins under the tokenized deposit framework represents a structurally different risk profile. A tokenized deposit issued by a federally chartered bank carries deposit insurance (subject to per-depositor limits), is subject to bank examination on a continuous basis, and falls under existing banking law rather than a new stablecoin-specific regime.

This is a qualitatively different transparency architecture, bank examiners have continuous access to reserve books, not just month-end snapshots. As this product category develops, it raises a legitimate question about whether USDC's attestation-based model, even under the GENIUS Act, offers the same transparency depth as a bank-issued alternative.

Institutional Adoption and What It Signals About Liquidity

The trajectory of institutional adoption matters for a specific reason in this analysis: liquidity and redemption depth. Regulatory compliance enables institutional participation; institutional participation deepens the redemption market; deeper redemption markets compress the magnitude and duration of depegs when stress occurs.

Through 2025–2026, major payment networks, corporate treasury programs, and financial institutions have expanded USDC integrations publicly. Settlement infrastructure providers have incorporated USDC into cross-border payment rails. Asset managers have used USDC as collateral in structured products.

These integrations do not eliminate reserve risk, but they do create a larger and more distributed set of counterparties capable of absorbing redemption pressure, which shortens the stress window a trader must plan around.

The practical implication for stablecoin payment rails is that USDC's regulatory compliance has converted into commercial adoption in a way that meaningfully exceeds what attestation quality alone would predict. Regulation created the permission structure; institutions made their own credit assessments within that structure.

Useful context for understanding this dynamic is the GENIUS Act Stablecoin regulatory theme and the broader stablecoin institutional buildout occurring across the market, both of which reflect how regulatory clarity converts into adoption velocity.

What Regulation Can and Cannot Do

A clean summary of the regulatory picture as of October 2026:

The table illustrates the boundary precisely. Regulation addresses what is disclosed, what assets qualify, and what legal rights holders have. It does not and cannot guarantee that reserve counterparties remain solvent in the interval between the last attestation and the next one.

A federally licensed USDC issuer operating fully within GENIUS Act requirements would still have had $3.3 billion in deposits at SVB on March 9, 2023, and still would have had no obligation to disclose that exposure mid-cycle.

The regulatory tailwinds behind USDC are real: compliance creates institutional access, institutional access creates liquidity depth, and liquidity depth compresses depeg duration. But regulation strengthens the framework around the attestation gap without closing it.

Traders pricing USDC as categorically safer than alternatives because of its regulatory positioning should be precise about which risks regulation actually addresses, and which it leaves structurally open.

How USDC Functions as Margin Collateral: Live Pricing, Not Peg Assumption

USDC margin collateral is marked at its live market price, not its nominal $1.00 peg. This single mechanical fact is the foundation of every calculation in this section.

When a platform marks your USDC at $0.95, your available margin is $0.95 per token, regardless of whether BTC, ETH, or any other underlying asset has moved a single tick.

The collateral loss is immediate, automatic, and separate from your position's P&L.

This differs from how most traders intuitively model stablecoin risk. The common assumption is that stablecoin margin is "safe" collateral that stays flat while the position's underlying asset drives gains and losses. In reality, the collateral leg and the position leg can move adversely at the same time, and on leveraged books, those two sources of loss compound rather than offset.

Scenario A, No Depeg: 50x BTC Long, Step by Step

This is the baseline mechanics, stated precisely so the depeg scenario is directly comparable.

Setup:

• -Deposited collateral: 10,000 USDC, marked at $1.00 = $10,000 effective margin
• -Instrument: BTC perpetual futures
• -Leverage: 50x
• -Position size: $10,000 × 50 = $500,000 notional
• -Entry price: $60,000 per BTC
• -BTC units controlled: $500,000 ÷ $60,000 = 8.333 BTC

BTC rises 1%:

• -New BTC price: $60,600
• -Position gain: 8.333 BTC × $600 = +$5,000
• -Return on deposited margin: $5,000 ÷ $10,000 = +50%
• -Effective margin after gain: $15,000
• -Approximate liquidation distance from entry (isolated margin, ~maintenance margin ≈ 0.5% of notional): roughly 1.9% adverse price move from entry before the position was opened

Key takeaway from Scenario A: At 50x leverage on a $10,000 USDC deposit, a 1% BTC price move generates a 50% return on capital. The collateral held its value, and the liquidation buffer depended solely on BTC's price action.

Scenario B, USDC Depegs to $0.93: Same Position, Different Collateral Reality

This scenario replicates the type of event that occurred during the SVB-related weekend in March 2023, when USDC fell sharply on secondary markets before a government backstop restored confidence.

Setup (identical to Scenario A):

• -Deposited collateral: 10,000 USDC
• -Leverage: 50x
• -Position size opened at $60,000 BTC: $500,000 notional

USDC depegs to $0.93, BTC has not moved:

• -Effective margin: 10,000 × $0.93 = $9,300
• -Margin lost to depeg alone: $700 (7% reduction in collateral value)
• -Position notional unchanged: $500,000
• -Margin-to-notional ratio: $9,300 ÷ $500,000 = 1.86%

At 50x leverage, the maintenance margin threshold is approximately 1% of notional (platform-dependent). With effective margin now at 1.86% of notional after the depeg alone, the liquidation buffer has narrowed from roughly 1.9% BTC adverse move to approximately 0.86% BTC adverse move, before BTC has done anything at all.

In concrete terms: a trader who believed they had a $1,000+ cushion against liquidation now has roughly half that, consumed entirely by a stablecoin event that appeared unrelated to their BTC thesis.

If BTC also falls 0.5% during the same event (risk-off correlation):

• -BTC P&L: 8.333 BTC × (−$300) = −$2,500
• -Total margin after depeg and BTC loss: $9,300 − $2,500 = $6,800
• -Margin-to-notional ratio: 6,800 ÷ 500,000 = 1.36%
• -Distance to liquidation: approximately 0.36% further BTC decline

The two adverse moves are not additive in a simple sense, they are multiplicative in their effect on liquidation distance at high leverage.

Liquidation Price Sensitivity Table: USDC Depeg Across Leverage Levels

The table below shows, for a $10,000 USDC deposit with BTC entered at $60,000, how a USDC depeg alone (no BTC move) reduces the effective safety margin before liquidation. Approximate liquidation distances assume isolated margin and a maintenance margin of ~0.5% of notional.

*Calculations are illustrative and assume isolated margin, 0.5% maintenance margin ratio, and no funding accrual. Actual liquidation thresholds depend on the platform, product, and account tier.*

The pattern is stark. At 10x leverage, a 10% depeg reduces liquidation headroom modestly, the position survives. At 100x leverage, a 5% depeg pushes the trader within a fraction of a percent of liquidation before BTC moves. At 500x leverage, a 3% depeg alone is sufficient to trigger liquidation of the full position.

CoinUnited.io Context: Leverage and Collateral Risk at Extreme Multiples

At leverage levels in the hundreds or thousands, even a fraction-of-a-cent movement in USDC's mark price has direct, measurable consequences for margin health, the table above illustrates this at 500x; at 2000x, the arithmetic is more extreme still.

This is not a theoretical risk. A USDC mark price of $0.998, a 0.2% drift from peg, is within the normal intraday variation range for stablecoins and would eliminate a material portion of the liquidation buffer at four-digit leverage multiples. Traders using USDC as margin at high leverage should treat collateral price stability as a first-order risk parameter, not a background assumption.

Funding Rate Interaction During a Depeg Event

Perpetual futures positions accrue funding payments at regular intervals, typically every 8 hours. When USDC is the margin and settlement currency, all funding flows are denominated in USDC. During a depeg event, this creates an asymmetric real-value effect:

• -Funding received (long pays short, or vice versa): The nominal USDC amount received is worth less in USD terms. A 0.0026% 8-hour funding receipt on a $500,000 notional position = $13.00 USDC. At $0.93, that $13.00 USDC is worth $12.09 in real purchasing power, a small but real haircut.
• -Funding owed: Conversely, a trader who owes funding during a depeg is paying in depreciated USDC. The $13.00 USDC payment costs only $12.09 in real terms, a minor benefit.

The funding interaction is a secondary effect compared to the collateral margin impact, but it compounds over time. In a sustained depeg lasting 48–72 hours, multiple funding cycles settle in depreciated USDC, eroding the real value of accumulated funding receipts for traders on the receiving side.

For context: as of October 2026, the BTC perpetual 8-hour funding rate is +0.0026%, indicating a modestly long-biased market. ETH's equivalent rate is +0.0009%. These rates determine which side pays, and by how much, during each settlement window.

Risk Management Strategies for USDC-Margined Leveraged Positions

Four practical approaches reduce exposure to the collateral-depeg risk described above.

1. Split margin across asset types. Holding a portion of margin in BTC or ETH rather than exclusively in USDC means that a stablecoin-specific crisis does not impair the entire collateral base. BTC and ETH carry their own volatility, but they are not correlated to stablecoin reserve counterparty failures in the same direction during an SVB-type event.

2. Set stop-losses that account for collateral risk, not just asset price risk. A stop-loss calibrated to BTC's price action alone does not protect against collateral erosion. The relevant metric is the liquidation price given current effective margin, which means recalculating liquidation distance whenever the USDC mark price moves materially.

At high leverage, this recalculation should be near-continuous during periods of stablecoin market stress.

**3. During periods of banking sector stress, the relevant signal is the cash-deposit component of reserves, the category that was exposed to SVB. A rising share of T-bill holdings relative to bank cash deposits reduces the counterparty failure risk. Conversely, a rising bank cash component warrants heightened attention, particularly if those counterparties are regionally concentrated.

4. Size positions to survive the 48–72 hour depeg window without hitting liquidation. Historical evidence from the SVB event suggests that a government backstop or market recovery can restore peg within one to three days.

A position sized so that a 10–15% collateral haircut (a conservative depeg estimate) still leaves margin above liquidation threshold can survive the window without forced exit. This directly implies lower effective leverage than the instrument maximum when USDC is the sole collateral asset.

The interaction of stablecoin regulatory frameworks such as the GENIUS Act with reserve requirements does not eliminate the attestation-gap risk, regulation can mandate reserve asset classes and redemption rights, but it cannot prevent a reserve counterparty from failing between reporting dates.

Risk management at the position level remains the trader's responsibility, regardless of the regulatory environment around the issuer.

USDC's DeFi Footprint: From Liquidity Pair to Systemic Load-Bearer

USDC occupies a structural role in decentralized finance that extends well beyond its function as a simple stable medium of exchange. Across lending protocols, automated market makers, and collateral frameworks, USDC is a foundational primitive, which means that when its peg comes under stress, the effects propagate through the ecosystem in ways that most holders never anticipate.

As of 2025–2026, USDC functions as a primary liquidity pair on the major AMMs, a collateral asset in protocols that mint other stablecoins, a base-currency money market on Layer-2 networks including Arbitrum, Base, and Solana, and a settlement rail for structured DeFi products. Each role creates a distinct contagion pathway during a depeg event.

Curve 3Pool Mechanics During a Depeg

The Curve 3pool, composed of USDC, USDT, and DAI, is one of the most important stablecoin liquidity venues in DeFi. Under normal conditions, the pool maintains near-equal composition because all three assets trade at or very close to $1.00, and its invariant pricing curve is calibrated for low-slippage swaps between assets assumed to be fungible.

When USDC depegs, the arbitrage mechanics work as follows:

1. Arbitrageurs holding USDC, or simply wanting to exit, sell USDC into the pool, receiving USDT or DAI in return.
2. The pool's USDC balance grows; its USDT and DAI balances shrink.
3. As the pool becomes USDC-heavy, the effective price of USDC within the pool drops below par, and slippage for USDC sellers increases non-linearly.
4. At the same time, USDT and DAI become scarcer within the pool, briefly trading at a premium to par on the Curve venue itself.

During the March 2023 SVB episode, this composition shift was observable in real time: the 3pool became heavily weighted toward USDC as holders sought any exit at any cost. A large seller attempting to liquidate a significant USDC position through Curve during that weekend faced meaningful slippage precisely because everyone else was trying to do the same thing through the same exit.

This matters for protocol-level risk because DAI, which held USDC as a significant portion of its collateral base through the PSM (Peg Stability Module), was simultaneously pulled toward a depeg by the falling value of its own collateral. The 3pool stress and the DAI collateral stress were not independent events; they were the same event, expressed in two different protocol layers.

Aave, Lending Protocol LTV Dynamics, and Liquidation Cascades

In lending protocols such as Aave, USDC is accepted as collateral, meaning users can deposit USDC and borrow other assets against it. Protocols set a loan-to-value (LTV) ratio for each collateral asset; if a depositor's collateral falls in value relative to their debt, the protocol triggers automated liquidation.

Consider a simplified example:

At $0.87 per USDC, a borrower who posted USDC collateral against a near-maximum loan is already insolvent by protocol math, not because any crypto price moved, but because the stablecoin they used as collateral lost its peg. The liquidation engine does not distinguish between a borrower whose ETH collateral crashed and one whose USDC collateral depegged. Both trigger automated sells.

This creates a liquidation cascade unrelated to any underlying crypto asset price move. Liquidated USDC collateral flows onto the market as forced supply, putting further downward pressure on the USDC price, which in turn pushes other borrowers toward their liquidation thresholds. The feedback loop is mechanical.

The severity depends on how many borrowers sit near their LTV limits at the time of the depeg, and how much of the lending protocol's total collateral base is USDC-denominated. Protocols with USDC concentration in their collateral books carry this risk asymmetrically.

AMM Impermanent Loss Amplification in USDC Pairs

Liquidity providers in USDC/ETH or USDC/BTC pools face a compounding exposure during a depeg that pure spot holders do not.

In a standard xy=k AMM pool, liquidity providers hold a synthetic position: as the price ratio between the two assets shifts, the AMM automatically rebalances by selling the appreciating asset and buying the depreciating one. Under normal conditions, this creates impermanent loss when the two assets diverge in price.

During a USDC depeg, the mechanism works against the LP in both directions simultaneously:

• -USDC is falling relative to its intended $1.00 value.
• -ETH or BTC is (likely) stable or appreciating in nominal USD terms.
• -The AMM rebalances by selling ETH/BTC into a falling USDC.
• -The LP ends up holding more USDC and less ETH/BTC than they started with.
• -When the depeg resolves (if it does), the LP has already sold the appreciating asset at a loss-adjusted rate.

This is not impermanent loss in the conventional sense, it is loss that locks in during the depeg window and may not reverse even if USDC returns to par, because the pool has already executed the unfavorable trades.

An LP in a USDC/ETH pool who held through the March 2023 weekend experienced this dynamic: the pool sold ETH into a collapsing USDC price, then rebought ETH at higher prices after the peg recovered.

USDC Yield in DeFi: Comparing Returns Against Attestation-Gap Risk

In the 2025–2026 environment, USDC yield opportunities in DeFi span several categories:

• -Lending protocol supply rates: Depositing USDC into lending markets on Arbitrum, Base, and Solana earns variable rates driven by borrow demand. Rates compress during low-leverage environments and expand during periods of high speculative activity.
• -Stablecoin-to-stablecoin LP yields: Providing USDC/USDT or USDC/DAI liquidity on low-slippage AMMs like Curve generates swap fee income plus, in many cases, token incentive rewards. These pools carry lower impermanent loss risk than USDC/ETH pools under normal conditions, but concentrate depeg contagion risk when any pool member depegs.

The critical question for any DeFi yield strategy is whether the APY on offer compensates for the attestation-gap risk, the probability that a reserve counterparty failure occurs between monthly reports and causes a temporary or permanent depeg.

A lending protocol offering a few percentage points annually in USDC supply yield does not price in a scenario where USDC depegs to $0.87 for 72 hours, as it did during the SVB episode. The expected loss from even a low-probability depeg event of that magnitude can exceed many months of earned yield.

Protocol Risk Concentration: On-Chain vs. Custodial Distribution

On-chain data trends suggest that a substantial and growing share of USDC's circulating supply resides in smart contracts rather than exchange hot wallets or institutional custodians. This concentration has structural implications:

• -Smart contract custody means the USDC is governed by code that cannot exercise discretion during a crisis. A lending protocol will liquidate a borrower's USDC collateral at $0.87 as mechanically as it would at $1.00, the protocol has no ability to wait for the peg to recover.

The trend toward increasing smart-contract concentration of USDC supply is a one-way ratchet toward more mechanical, non-discretionary depeg response. As DeFi protocols deepen their USDC integrations on Arbitrum, Base, and Solana, all of which saw material liquidity growth in 2025–2026, the share of USDC supply governed by immutable on-chain logic continues to rise.

Mitigation Through Protocol Design: Proof-of-Reserve Oracles and Their Limits

Newer protocol designs attempt to close the attestation gap at the smart contract level. The primary mechanism is a proof-of-reserve oracle, an on-chain data feed, such as those provided by Chainlink's Proof of Reserve framework, that reports reserve backing in near real-time rather than monthly.

In a protocol using such a feed, a smart contract can be configured to:

• -Pause USDC deposits if the oracle reports reserve coverage falling below a threshold.
• -Reduce the accepted LTV for USDC collateral automatically if the feed signals stress.
• -Trigger governance alerts before a depeg reaches secondary markets.

The approach is meaningful but has current limitations:

1. Oracle failure modes introduce new risk. A manipulated or lagged oracle feed could trigger false positives (pausing a healthy protocol) or false negatives (failing to catch a real shortfall).
2. Adoption is partial. Not all protocols integrated with USDC have implemented proof-of-reserve triggers. Protocols that have not remain fully exposed to the attestation-gap risk described above.
3. The fundamental constraint remains: no oracle can report the failure of an off-chain banking counterparty faster than that failure is disclosed by the counterparty or its regulators. SVB's seizure was a regulatory action taken on a Friday morning; on-chain oracle feeds had no advance signal.

Protocol-level design improvements narrow the contagion window, but they do not eliminate the structural gap between monthly attestation snapshots and continuous reserve verification.

For DeFi participants, whether as liquidity providers, borrowers, or yield farmers, the practical implication is that USDC's DeFi integrations create second-order exposures that compound the first-order reserve risk described in earlier sections of this analysis.

Understanding each protocol's specific USDC exposure, collateral treatment, and oracle infrastructure is a prerequisite for sizing any position that depends on USDC maintaining its peg through a stablecoin stress scenario.

That amplification is fastest and largest precisely when leverage is highest and exit windows are narrowest, the conditions under which it causes the most damage.

Monitoring the stablecoin payment rails environment for early signs of 3pool composition stress or elevated USDC borrow rates on lending protocols is one practical leading indicator of building depeg risk.

Cross-market positioning around USDC requires treating the stablecoin not as a neutral unit of account but as an asset with its own supply, regulatory, and rate dynamics, each of which generates signals readable across crypto perpetuals, forex CFDs, commodities, and equity indices simultaneously.

USDC Supply Expansion as a Crypto Sentiment Indicator

USDC minting and burning activity functions as a leading indicator of crypto market risk appetite, not a coincident one. When large institutional participants intend to deploy capital into crypto, they must first acquire a stablecoin, and for regulated, US-domiciled entities, USDC is frequently the instrument of choice.

Rapid net minting of USDC therefore represents capital staging: dry powder assembled on-chain, not yet deployed into BTC or ETH positions.

The signal reads in both directions. Sustained net minting across multiple days, visible through on-chain mint/burn transaction data, tends to precede risk-on phases, as that capital seeks yield or directional exposure.

Sustained net burning, where USDC is redeemed for dollars and exits the on-chain ecosystem, signals the reverse: capital retreating to fiat, whether from risk aversion, regulatory concern, or simply better off-chain yield alternatives.

Reading this in real time requires monitoring on-chain USDC transfer volume to exchange deposit addresses alongside raw mint/burn data. A spike in minting accompanied by large inflows to exchange hot wallets is a more practical setup than minting alone, because it indicates the capital is moving toward trading venues rather than sitting in cold storage.

USDC/USDT Market Share Shifts as a Regulatory Risk Proxy

The relative market share of USDC versus USDT is not a simple competition metric, it is a proxy for the direction of US regulatory sentiment, readable in real time.

When USDC gains market share against USDT, it typically reflects one of two conditions: US regulatory frameworks are moving toward clarity (making the compliant, US-regulated issuer more attractive), or institutional participants are rotating toward the asset with cleaner reserve documentation ahead of expected scrutiny.

When USDT gains share, it often reflects the opposite: US regulatory uncertainty driving capital toward the offshore-domiciled issuer that operates outside direct SEC or Treasury reach, or emerging-market capital flows that have historically preferred USDT's liquidity depth.

The tradeable implication is directional. A multi-week trend of USDC market share expansion, coinciding with legislative progress on frameworks like the GENIUS Act stablecoin regulatory structure, often precedes a broader crypto risk-on rotation, because institutional on-ramps are widening.

A sharp reversal in that trend, particularly if accompanied by large USDC redemptions, is a warning signal worth hedging in crypto perpetuals positioning.

Monitor the USDC/USDT share ratio on major DEX aggregators and the Curve 3pool composition. When the 3pool becomes heavily weighted toward USDC relative to its typical balance, that imbalance reflects net selling of USDC into the pool, an early stress signal before any price-feed depeg becomes visible.

Interest Rate Sensitivity and the Yield-Bearing Alternative Dynamic

USDC reserve yield is structurally tied to short-duration US Treasury bill rates.

From the USDC holder's perspective, holding non-yield-bearing USDC in a high-rate environment has an opportunity cost, making yield-bearing alternatives, such as tokenized T-bill products, yield-bearing stablecoins, or on-chain money market instruments, comparatively more attractive.

Traders should watch this dynamic when the Fed signals rate trajectory changes. A dovish pivot, rate cuts, tends to compress the yield differential, making plain USDC relatively more competitive against yield-bearing alternatives, which can support supply expansion and associated crypto risk-on signals.

Conversely, a Fed hawkish pivot, visible in instruments like Fed rate hike macro signals, may accelerate supply contraction as USDC holders seek yield elsewhere, tightening on-chain dollar liquidity.

Forex Market Parallel: Collateral Devaluation Without an FX Move

The SVB depeg episode illustrated a risk category that forex CFD traders rarely price: synthetic rate shifts caused by collateral devaluation rather than underlying FX movement.

When USDC depegs, any position margined in USDC experiences a reduction in effective collateral value. A trader holding a USD/JPY or EUR/USD CFD position, with margin posted in USDC, sees their effective margin decrease in proportion to the depeg depth, even if USD/JPY or EUR/USD has not moved a single pip. The FX position is fine; the collateral backing it is not.

During the SVB weekend, this was not a theoretical risk. USDC effective exchange rates against EUR and GBP shifted because the stablecoin itself was trading below par, meaning any USDC-denominated margin account experienced a dollar-equivalent haircut with no underlying FX catalyst.

Traders who had not sized their FX positions to absorb a collateral shock in addition to normal FX volatility faced margin calls from a source entirely outside the FX market.

The practical risk management implication: when holding leveraged forex CFD positions margined in USDC, the liquidation price is a function of both the FX rate and the USDC/USD effective rate. These are two separate risk factors, and only one of them is visible in the standard FX price feed.

Gold (XAUUSD) and USDC Flows During Banking Stress

Historically, periods of banking-sector stress that impair USDC confidence produce a recognizable cross-market pattern: USDC is sold or redeemed, and a portion of that capital rotates into gold (XAUUSD) as a non-counterparty-dependent store of value. This is the same logic that drives USD-to-gold rotation during dollar-system stress events, applied at the stablecoin layer.

The structural advantage for positioning this rotation is timing. XAUUSD trades 24/7 on CoinUnited, including weekends, meaning an SVB-type Friday event allows gold positioning while USDC uncertainty remains unresolved and traditional commodity venues are dark.

The weekend gap risk that exists on traditional gold futures does not apply to the XAUUSD CFD on the platform.

US500 and Bank-Sector Weighting During Stablecoin Stress

A USDC depeg caused by a banking counterparty failure is not isolated to crypto markets. The US500 index will price that credit event when traditional equity markets open, but the stress unfolds over the prior weekend in stablecoin markets.

US500 trades 24/7 on CoinUnited, including weekends. A trader reading the USDC stress signal on a Friday evening, through exchange spread data, DEX pool imbalances, or official communications, can establish a US500 short before any traditional equity venue opens.

The SVB timeline demonstrated that the window between a bank seizure announcement and Monday's equity open is a period where the price discovery happens in crypto markets before it moves to equities.

This is a concrete structural advantage, not a theoretical one. The same 24/7 availability that allows weekend crypto positioning also allows weekend equity-index positioning, and the two are linked when the stress catalyst is a banking-sector counterparty failure.

*Trading hours are per instrument. CoinUnited crypto perpetuals and 64 CFDs, including XAUUSD and US500, trade 24/7 with weekends included; most other CFDs follow their underlying market session.*

Cross-Market Monitoring Toolkit

Reading USDC risk across markets in real time requires a small, focused set of on-chain and market-structure data sources:

• -USDC/USDT spread on major DEXes: The live exchange rate between USDC and USDT on decentralized exchanges functions as a real-time stress thermometer. A spread wider than a few basis points, USDC trading below USDT, signals market concern before any official communication.
• -Curve 3pool composition ratio: Under normal conditions, the 3pool holds roughly equal weights of USDC, USDT, and DAI. A composition shift heavily toward USDC means arbitrageurs and risk-averse holders are net-selling USDC into the pool. This is the earliest on-chain stress signal, typically preceding exchange spread widening.
• -On-chain USDC mint/burn volume: Net daily or weekly mint/burn flows show whether institutional participants are adding or withdrawing dollar exposure through USDC specifically, distinguishing USDC-specific flows from general stablecoin market movements.
• -USDC-denominated funding rates on perpetual futures: If funding rates on USDC-margined perpetuals diverge materially from USDT-margined equivalents, it signals that traders are discounting USDC collateral relative to USDT, a market-structure stress indicator.

No single indicator is sufficient. The SVB depeg moved from invisible to critical within hours, faster than any monthly attestation framework could signal. The monitoring toolkit above operates continuously, providing the intra-cycle visibility that formal reserve reports structurally cannot.

The core cross-market discipline: USDC is not a passive backdrop. Its supply, regulatory positioning, reserve structure, and live peg are active inputs into crypto perpetuals, forex collateral mechanics, gold positioning, and equity-index risk. Traders who monitor all four simultaneously hold an informational edge that single-asset analysis cannot replicate.

Practical Playbook: How Traders Can Monitor and Hedge the Attestation Gap

The attestation gap is not a theoretical risk. This playbook translates that structural reality into six concrete steps, ordered by implementation priority, followed by a position-sizing formula for leveraged traders.

Step 1, Know Your Attestation Calendar

That publication lag is itself a secondary blind spot: you do not know what the reserves looked like at the snapshot date until the report appears. Treat the pre-publication window, particularly when macro stress is elevated (bank earnings season, Fed stress test release dates, regulatory announcement windows), as a heightened-risk period.

Practical actions:

• -Note the expected publication date each month and flag it in your trading calendar alongside scheduled macro events within the same window.
• -If a prior attestation showed material cash-at-bank exposure rather than pure T-bill holdings, the next pre-publication window carries greater counterparty uncertainty.
• -If you are running heavy USDC collateral at high leverage heading into a known risk window, consider reducing that exposure before the window opens rather than reacting during it.

Step 2, Monitor Real-Time Peg Health Proxies

The Curve 3pool weight is particularly practical because it updates continuously. A pool heavily weighted toward USDC signals that sophisticated market participants are offloading USDC for USDT and DAI, the composition shift precedes spot price moves because it reflects informed selling pressure, not retail panic.

Step 3, Collateral Diversification

Concentrating 100% of trading margin in any single stablecoin creates a single point of failure. Each stablecoin carries a distinct risk profile: USDC carries attestation-gap and banking counterparty risk; USDT carries reserve opacity and regulatory risk; algorithmic stablecoins carry depeg mechanics specific to their design.

A practical split might allocate margin across USDC, USDT, and a non-stablecoin asset such as BTC or ETH. Non-stablecoin collateral introduces price volatility risk to the margin balance, but that volatility is uncorrelated with stablecoin-specific depeg events.

The goal is not to eliminate risk but to avoid having all collateral exposed to the same failure mode simultaneously. Treat collateral allocation as a portfolio decision, not a default setting.

Step 4, Pre-Positioning for Banking Stress Weekends

USCC stress is most acute when traditional banking channels are closed. The SVB seizure was announced on a Friday.

Specific risk windows to monitor:

• -Bank earnings seasons: quarterly results reveal balance sheet stress before regulators act
• -Fed stress test release dates: results can trigger rapid repricing of bank credit risk
• -Regulatory announcement dates: enforcement actions or licensing decisions often cluster around congressional or agency calendars

Strategies for these windows:

• -Reduce USDC margin exposure in the days before the window, not during it
• -Rotate into assets that benefit from safe-haven flows during banking stress, gold (XAUUSD) historically attracts capital during bank failures
• -On CoinUnited, XAUUSD trades 24/7 including weekends, meaning a Friday-evening banking event allows gold positioning while USDC uncertainty is unresolved and traditional venues remain closed. The US500 index also trades 24/7 on the platform, enabling positioning ahead of a Monday open during a weekend banking crisis

Step 5, Using Perpetual Funding Rates as a Depeg Early-Warning Signal

When USDC is used as collateral for perpetual futures, funding rates are settled in USDC. When market makers begin pricing in collateral devaluation risk, the funding rate on USDC-margined perpetuals tends to diverge from equivalent USDT-margined products before the divergence appears on spot markets.

This divergence is a forward-looking signal. Market makers running delta-neutral books are exposed to collateral risk and will adjust their funding bids accordingly. A sharp widening of that spread, USDC-margined funding running materially cheaper than USDT-margined funding, suggests sophisticated participants are discounting USDC collateral.

Practical check: compare funding rates on equivalent contracts across USDC-margined and USDT-margined books at intervals during elevated macro stress windows. A sustained divergence warrants collateral review before any position adjustment.

Step 6, Hedging Through Pair Trades and Structured Protection

Direct hedging of USDC depeg risk is limited by liquidity and cost, but several instruments are available.

USDC/USDT pair trade: Going short USDC and long USDT (or vice versa) as a stablecoin pair position is the most liquid and direct hedge. In normal conditions the spread is minimal and carry is low. During stress, the spread widens rapidly, providing a hedge against collateral devaluation.

The trade is most effective when entered before stress materializes, the bid/ask widens significantly once a depeg is in progress.

DeFi options protocols: Some DeFi options platforms offer peg protection structures on USDC. These function similarly to put options, paying a premium in exchange for the right to exit USDC at or near par. Liquidity is thin relative to traditional options markets, and premium costs during elevated macro stress can be prohibitive.

Assess availability and cost during calm periods, not during the event.

Practical cost-benefit: For most active traders, the USDC/USDT pair trade combined with collateral diversification (Step 3) and pre-positioning (Step 4) is more operationally practical than structured DeFi options, which require protocol familiarity and carry smart contract risk.

Position-Sizing Rule: Adjusting Maximum Leverage for Stablecoin Stress

At high leverage, a small USDC depeg directly compresses margin buffers before the underlying asset moves at all. The relationship is mechanical.

Formula, Adjusted Maximum Leverage:

``` Max Safe Leverage = 1 / (Liquidation Buffer % + Expected Depeg %) ```

Where:

• -Liquidation Buffer % is the margin fraction you want to preserve above the liquidation threshold (e.g., 2% for a 50x position)
• -Expected Depeg % is your stress-scenario estimate for USDC devaluation during an acute event

Worked examples, impact of a 0.5% USDC depeg on margin buffers at varying leverage:

At 100x leverage, a 0.5% USDC depeg consumes more than half the available margin buffer before BTC, ETH, or any other underlying asset has moved a single tick. At 500x, the depeg alone can bring a position to or past its liquidation threshold.

At the upper end of that range, even a fraction-of-a-cent stablecoin fluctuation is a material liquidation input. Position sizing must account for collateral volatility as a separate risk layer from underlying asset price risk. For current fee tier rates applicable to your trading volume, refer to the live fee schedule.

Practical rule of thumb: When USDC stress indicators are elevated, 3pool weight above 40%, USDC/USDT spot spread widening, on-chain redemptions accelerating, apply a stress depeg assumption of at least 3-5% to your liquidation distance calculation and reduce maximum leverage accordingly. In calm conditions with no macro risk windows approaching, a lower assumption is appropriate.

The key discipline is making the adjustment before the event, not during it.
