A stablecoin makes a simple promise.
One token should remain worth one dollar.
That promise is easy to keep when markets are calm. The real test comes when many holders want dollars at the same time.
A stablecoin run begins when trust falls faster than the issuer can meet redemptions.
A stablecoin survives a run only when holders can get cash quickly, at par, and without doubt.
How a Stablecoin Run Starts
A run does not always begin with a large loss.
It can begin with a question.
A bank may fail. A reserve report may look weak. A blockchain may stop. An issuer may delay withdrawals. A rumor may spread faster than the facts.
Holders then face a choice.
They can wait and trust the peg. Or they can sell first.
This creates a first-mover advantage. Early sellers may receive one dollar. Late sellers may face a lower market price.
The fear can become self-reinforcing:
- Holders ask for redemption.
- The issuer uses cash reserves.
- The issuer may need to sell other assets.
- Large sales can reduce market prices.
- New losses create more fear.
- More holders try to leave.
The IMF describes this loop as a link between redemptions, asset sales, falling bond prices, and further redemptions.1
Safe Reserves Must Also Be Liquid
The word backed is not enough.
A stablecoin may hold assets worth more than its tokens. Those assets may still be hard to sell quickly.
Cash is ready for redemption. Short-term government bills are usually liquid. Longer bonds, loans, corporate debt, and cryptoassets can lose value or take time to sell.
The key question is not only:
Are the reserves valuable?
It is also:
Can the issuer turn them into cash today?
Federal Reserve Governor Michael Barr said stablecoins remain stable only when holders can redeem promptly at par during many conditions, including market stress.2
Reserve quality and reserve liquidity are different tests.
A long-term bond may be high quality. Its price can still fall when interest rates rise. Selling it during stress may create a loss.
A strong reserve portfolio therefore needs enough cash and short-term assets to meet sudden withdrawals.
Redemption Rules Decide Who Gets Out First
Many retail users cannot redeem directly with the issuer.
They may need to sell on an exchange or decentralized market.
This creates two prices:
- the issuer’s official redemption value
- the market price available to ordinary holders
The IMF notes that many retail holders rely on secondary markets. Prices can move below one dollar during stress, especially when direct redemption has minimum sizes or limited access.3
The details matter:
- Who can redeem directly?
- Is there a minimum amount?
- How long does settlement take?
- Are redemptions available on weekends?
- Can the issuer charge a fee?
- Can the issuer pause withdrawals?
A stablecoin may promise one dollar while giving the fastest exit only to large institutions.
The USDC Depeg Shows How Fast Stress Can Spread
The March 2023 USDC episode gives a clear example.
Circle disclosed that it could not access $3.3 billion of reserves held at Silicon Valley Bank. The amount was about 8% of USDC reserves at the time.4
Redemption requests surged.
Primary-market operations were closed over the weekend. USDC then traded below one dollar on secondary markets.
The stress also spread to other tokens. Some decentralized systems used USDC as collateral or as part of their peg mechanism.
The Federal Reserve found that the event linked a traditional bank failure with a wider stablecoin depeg.4
USDC later returned to par after authorities protected Silicon Valley Bank depositors.
The lesson is not that every bank deposit is unsafe.
The lesson is that reserve access matters as much as reserve value.
Even Perfectly Safe Reserves May Not Stop a Run
A stablecoin can face pressure even when its reserves are safe.
A June 2026 Federal Reserve paper shows how digital money can become fragile through network effects and congestion costs.5
As more users rush to exit, blockchain fees may rise. Trading can slow. Liquidity can move away from the market.
Each holder then expects the next holder to leave earlier.
The run becomes a coordination problem.
This means a strong stablecoin needs more than good assets.
It also needs:
- working blockchains
- reliable banks
- active market makers
- liquid exchanges
- clear communication
- fast redemption operations
The full system must work at the same time.
Who Carries the Loss?
The first holder to redeem may receive one dollar.
The last holder may sell below one dollar.
This difference shows who carries the downside.
| Risk test | Stronger sign | Warning sign |
|---|---|---|
| Reserve quality | Cash and short-term government assets | Loans, long bonds, risky tokens, unclear assets |
| Liquidity | Large cash buffer and short maturities | Assets that require large sales during stress |
| Redemption | Clear par redemption with short settlement | High minimums, delays, fees, or limited access |
| Custody | Segregated reserves and named custodians | Unclear ownership or concentrated uninsured deposits |
| Operations | Several banks, chains, and market routes | One bank, one chain, or one exchange as a bottleneck |
This table does not identify a risk-free token.
It shows where to look.
The weakest link may sit outside the blockchain. It may be a bank account, custodian, legal claim, or redemption process.
Yield Adds Another Risk Layer
A stablecoin peg and a stablecoin yield are not the same product.
The reserve assets may earn interest. The issuer may keep that income. A platform may also offer rewards through lending, market making, or promotional payments.
Each source creates a different risk.
Before using a yield product, ask:
- Who pays the yield?
- Is the token being lent?
- Is leverage involved?
- Can withdrawals be delayed?
- Does the product add another company between the holder and the issuer?
Higher yield does not make the peg stronger.
It usually adds another balance sheet, contract, or market strategy.
Regulation Can Reduce Risk, but Not Remove It
The United States created a payment-stablecoin framework in 2025. Regulators were still writing key implementation rules in 2026.
The Federal Reserve’s May 2026 Financial Stability Report highlighted reserve transparency and redemption rights as tools to reduce run risk.6
These rules can improve the market.
They can make reserves easier to compare. They can also define how and when users receive cash.
But regulation cannot prevent every failure.
Banks can face stress. Technology can stop. Fraud can occur. Markets can lose liquidity.
The goal is not to promise that a run is impossible.
The goal is to make the system more able to absorb one.
A Five-Question Stablecoin Checklist
Before using a stablecoin for payments, savings, or settlement, check five points.
1. What Backs the Token?
Look for a recent reserve report. Check the share held in cash, deposits, and short-term government assets.
2. Who Can Redeem?
Find out whether ordinary holders can redeem directly. Check minimum amounts, fees, and settlement time.
3. Where Are the Reserves?
Look for named banks and custodians. Check whether reserves are spread across several institutions.
4. What Happens During an Outage?
Review the issuer’s policy for weekends, blockchain failures, frozen accounts, and bank closures.
5. Where Does Any Yield Come From?
Separate the stablecoin from the product built around it. Lending and reward programs add risks that reserves alone do not cover.
These questions help the reader compare stablecoins without relying on brand size or market popularity.
What to Watch Next
Reserve Reports
Do issuers publish clear and frequent information about asset quality and maturity?
Redemption Performance
Can holders receive cash at par during busy markets and weekends?
Market Spread
Does the token trade close to one dollar across several exchanges and blockchains?
Banking Concentration
Does the issuer depend on a small number of banks or custodians?
Stress Planning
Does the issuer explain how it would handle a large wave of redemptions?
A stablecoin proves its strength during pressure, not during calm markets.
Conclusion
A stablecoin is not stable because its name includes the word stable.
It is stable when the full redemption chain works.
Good reserves matter. Fast access matters. Liquid markets matter. Legal rights and operational systems matter.
A strong token can still lose its peg for a short time. A weak token may look safe until trust disappears.
The best question is not:
Which stablecoin is always safe?
It is:
Can this stablecoin turn its reserves into cash quickly enough when everyone wants to leave?
Key Vocabulary & Phrases
