Stablecoins case study
Reading a Stablecoin Depeg Without Jumping to Conclusions
A price below one dollar is an observation, not a complete diagnosis. This case shows how to organize the evidence before deciding what a depeg may mean.
Evidence boundaries are reviewed against the primary references listed at the end. Read our editorial methodology.
The situation
Start with the facts available to the reader
A fictional dollar-referenced stablecoin, Harbor USD, trades between $0.985 and $0.992 for ninety minutes. The discount first appears on one exchange and later becomes visible on two decentralized pools. Social posts claim the issuer is insolvent, while the issuer says redemptions remain open.
The public reserve report is three weeks old. It lists cash, short-term government securities, and bank deposits, but it does not provide a live asset balance. Some exchange users also report delayed withdrawals. The task is not to predict the token's next price. It is to identify which facts describe market liquidity, which relate to the issuer's redemption obligation, and which claims still require evidence.
Every name and number in this scenario is fictional. The method is intended for reading disclosures and risk reports, not for deciding whether to buy, sell, or hold a stablecoin.
Evidence sheet
What each observation can and cannot support
The last column is deliberately strict. It prevents a useful signal from being stretched into a conclusion that needs different evidence.
| Observation | Useful for | Not proof of |
|---|---|---|
| The token trades at $0.985-$0.992 on visible venues. | Confirming a secondary-market price deviation and comparing its breadth across venues. | A reserve shortfall, fraud, or the final amount an eligible holder could receive through redemption. |
| The issuer states that redemptions remain open. | Locating the claimed conversion mechanism, eligibility rules, fees, minimum size, and timing. | Successful settlement for every holder unless completed redemptions or equivalent operational evidence can be verified. |
| A reserve report is three weeks old. | Reviewing reported asset composition, custody arrangements, maturity profile, and the reporting date. | The issuer's live balance sheet or current liquidity at the exact time of the price deviation. |
| Users report delayed exchange withdrawals. | Checking whether a venue-specific operational bottleneck could be limiting arbitrage or access. | An issuer-wide redemption halt, because an exchange withdrawal and an issuer redemption are different processes. |
Analysis path
Work from mechanism to conclusion
Separate the traded price from the legal claim
What exactly is trading below one dollar?The quoted price comes from buyers and sellers on a venue. It can move because of urgent selling, thin liquidity, withdrawal friction, transaction costs, or concern about the issuer. The price is important evidence of stress, but it does not by itself identify the cause.
The redemption claim is a different object. A reader should find who may redeem, what asset is delivered, whether the promise is at par, which fees or minimums apply, and how long settlement may take. A token can trade below par even while a narrower group of eligible customers can redeem at par, because not every market participant has the same access.
Trace the full redemption path
Can an ordinary holder reach the mechanism that supports the peg?Map the path from token holder to exchange, issuer, bank, custodian, and settlement account. Look for operating hours, identity requirements, geographic limits, queueing, fees, and minimum redemption size. These details determine whether the arbitrage mechanism is available in practice, not only on paper.
A venue withdrawal delay may prevent a user from moving tokens, but it is not automatically an issuer redemption failure. Conversely, a working exchange withdrawal does not prove that the issuer can satisfy large redemptions. Keeping those layers separate prevents one operational symptom from being generalized too quickly.
Read reserve quality, not only reserve size
What supports the promise, and when was it measured?A reserve total should be read together with asset type, maturity, liquidity, custody, concentration, encumbrance, and the reporting date. Cash and short-dated government securities behave differently from longer-duration, volatile, or related-party assets. An attestation can offer useful assurance about a stated point in time, but it is not the same as continuous verification.
The three-week-old report in this case narrows uncertainty about the earlier composition. It does not eliminate the need for current information. The correct statement is therefore limited: reported assets existed under the scope and date of that report, while the live position remains unobserved.
Test whether stress is narrow or system-wide
Does the same pattern appear across independent channels?Compare several venues, pool depths, order-book spreads, redemption status, settlement reports, and official disclosures. A discount isolated to one venue with a technical outage tells a different story from a persistent discount across independent markets combined with suspended redemptions.
Duration matters as well. A short deviation during a burst of selling can be a liquidity event; a persistent deviation after normal access returns deserves a different level of scrutiny. This comparison does not produce certainty, but it replaces a single screenshot with a structured evidence set.
Reasoned conclusion
Say what is supported, then preserve uncertainty
The defensible conclusion is narrower than either social-media extreme. Harbor USD is experiencing a real secondary-market depeg. Available facts suggest that both venue access and confidence may be affecting price formation. The evidence is not sufficient to establish an issuer reserve shortfall, and the issuer's statement alone is not sufficient to establish that redemptions are clearing normally.
A careful reader would keep monitoring completed redemption evidence, updated reserve disclosure, venue normalization, and the breadth and duration of the price deviation. That conclusion preserves uncertainty instead of turning a market symptom into an unsupported accusation or reassurance.
Claim boundaries
Keep the finding inside the evidence
This method can show
- Where and for how long the traded price differs from the reference value.
- Whether redemption rules are clear and accessible to the relevant holder type.
- What assets were reported, under which scope, and at what date.
- Whether stress appears isolated to one venue or across independent channels.
This method cannot show
- Live reserve sufficiency from a secondary-market price alone.
- Universal redemption access from an issuer's general statement.
- Issuer insolvency from an exchange withdrawal delay.
- Future price direction or whether holding the token is appropriate for a person.
Reader checklist
Repeat this process on another document
- Record the venue, timestamp, price, spread, and available depth.
- Find the contractual redemption terms and identify who is eligible.
- Separate exchange withdrawals from direct issuer redemptions.
- Read reserve composition, custodian, assurance scope, and report date together.
- Write a conclusion that states both the evidence and the remaining uncertainty.

FAQ
Questions this case should leave you asking
Does a price below one dollar prove that reserves are missing?
No. It proves that visible buyers and sellers are clearing below the reference value on the observed venue. Reserve sufficiency requires separate evidence about assets, obligations, custody, and redemption performance.
Is an attestation the same as an audit?
No. The terms can involve different scopes, procedures, periods, and assurance levels. Readers should check the exact report language, date, subject matter, and responsible firm.
Why can market price and redemption value differ?
Access restrictions, fees, settlement time, venue outages, risk limits, and uncertainty can prevent every market participant from using the redemption path immediately.
