A stablecoin depeg happens when a token trades away from its intended reference value. This guide examines historical depeg events, reserve failures, liquidity pressures, redemption mechanisms and warning signs for stablecoin holders.
A stablecoin depeg occurs when a token's market price moves away from its intended fixed value, usually one US dollar. Reserve problems, restricted redemptions, liquidity shortages or collapsing confidence can cause the deviation. For stablecoin holders and crypto traders, understanding these events helps distinguish temporary price fluctuations from possible permanent losses.
Key Takeaways

-
TerraUSD's May 2022 collapse demonstrated how algorithmic stablecoins can enter a death spiral.
-
Reserve transparency, redemption access and secondary-market liquidity help determine whether a stablecoin recovers.
-
Depegging can trigger liquidations, liquidity withdrawals and losses throughout decentralized finance.
Why Do Stablecoins Lose Their Peg?
Stablecoins maintain their target through collateral, redemption mechanisms and market arbitrage. A dollar token designed to trade at one dollar can still move above or below that value when market conditions change.
Three common structures carry different risks:
| Stablecoin structure |
Backing mechanism |
Main depeg risk |
| Fiat-backed stablecoin |
Cash, bank deposits and short-term government securities |
Reserve access or issuer solvency |
| Crypto-backed stablecoin |
Crypto collateral locked in smart contracts |
Falling collateral value and failed liquidations |
| Algorithmic stablecoin |
Supply adjustments and market incentives |
Confidence collapse and feedback loops |
A fiat backed stablecoin generally seeks sufficient reserves to cover outstanding tokens at full value. Eligible reserve assets may include cash equivalents and short-term US Treasury securities.
Crypto-backed systems depend on collateral and functioning liquidation mechanisms. Algorithmic stablecoins can be especially vulnerable when falling demand overwhelms their supply controls.
Major Stablecoin Depeg Events
Several notable examples show how similar price deviations can produce very different outcomes.

USDC Depeg: Silicon Valley Bank, March 2023
The USDC depeg followed the failure of Silicon Valley Bank (SVB).
Circle confirmed that approximately $3.3 billion of USDC reserves were held at the failed Silicon Valley Bank. This exposure created uncertainty about reserve access, leading USDC holders to sell the discounted token.
USDC fell to roughly $0.87 on March 11, 2023. DAI also declined because its stabilization mechanisms were exposed to USDC.
On March 12, the Federal Reserve, US Treasury and FDIC announced protections for SVB depositors. Circle subsequently confirmed reserve availability, and USDC recovered toward one dollar.
The Federal Reserve's financial stability report documents this episode.
UST Collapse and the Algorithmic Death Spiral
TerraUSD's May 2022 failure was different.
UST relied on conversions involving LUNA rather than conventional dollar reserves. Falling demand caused additional LUNA issuance, which undermined its market price.
That created a death spiral: more redemptions produced more LUNA, falling prices weakened confidence, and selling accelerated.
The UST collapse erased tens of billions of dollars in combined token market value. Unlike the USDC incident, restoring the original peg proved unsuccessful.
sUSD: Prolonged Depeg in 2025–2026
Synthetix's sUSD experienced prolonged instability across 2025–2026.
In its sUSD recovery announcement, Synthetix acknowledged trading below $0.70 and described changes intended to restore stability.
This demonstrates that a sustained deviation can persist even when a protocol continues operating. Recovery plans do not guarantee that token value returns to its target.
How Stablecoin Redemption and Arbitrage Work
Stablecoin prices depend on two markets.
The primary market handles issuance and redemption. The secondary market includes exchanges, trading venues and decentralized liquidity pools.
Suppose one token trades for $0.97 while eligible holders can redeem it for one dollar. Arbitrageurs may buy the discounted token and redeem it at full value.
That buying pressure can restore the peg.
But the redemption path matters. If redemption access is restricted, reserve access is uncertain or liquidity providers withdraw, the discount may persist.
Deep liquidity reduces price slippage. A local price on one venue does not necessarily represent the token's broader market value.
The distinction between primary and secondary stablecoin markets explains why redemption rights and exchange prices can diverge.
What Happens During a Stablecoin Depeg?
Consequences depend on severity, duration and the specific stablecoin's integration into digital assets markets.
A minor deviation may disappear through arbitrage. A major depeg can trigger a bank run, falling supply, rapid declines in market cap and forced liquidations in lending protocols.
Decentralized finance applications face additional risks when smart contracts use a depegged stablecoin as collateral.
Liquidity providers may withdraw assets from liquidity pools. Reduced depth makes additional selling more disruptive, potentially spreading losses across connected protocols.
Leading Indicators of Depeg Risk
Stablecoin holders can examine several warning signs before a serious depeg event:
-
Reserve composition: Review reserve reports, custodians and any external fund manager controlling backing assets.
-
Redemption rights: Check who can redeem one stablecoin for fiat currency, applicable fees and processing speed.
-
Liquidity depth: Monitor order books, liquidity pools and price differences between venues.
-
Supply changes: Watch for rapid redemptions, falling supply and persistent selling pressure.
-
Issuer concentration: Consider exposure to at least two independent issuers instead of relying on one stablecoin.
Yield-bearing tokens should not automatically be treated as cash equivalents. Higher yields may introduce lending, collateral or smart contract risks.
FAQs
What causes a stablecoin depeg?
A stablecoin depeg can result from inaccessible reserves, weak collateral, restricted redemption, liquidity shortages or collapsing confidence. The exact cause depends on the stablecoin's backing mechanism.
Can a depegged stablecoin recover?
Yes. A depegged stablecoin can recover when confidence, reserve access and redemption mechanisms improve. Recovery is not guaranteed, particularly after severe collateral losses or algorithmic failures.
Why did USDC lose its peg in March 2023?
USDC lost its peg after Circle disclosed $3.3 billion in reserves at Silicon Valley Bank. Uncertainty surrounding those deposits prompted selling, temporarily pushing USDC's price to approximately $0.87.
Do stablecoins always equal one dollar?
No. Major stablecoins target a fixed reference value, but their market prices can fluctuate. One dollar remains the intended peg, not a guaranteed trading price.
How can holders reduce stablecoin depeg risk?
Holders can compare issuer reserve disclosures, assess redemption access, monitor liquidity depth and diversify issuer exposure. These measures reduce concentration risk but cannot eliminate potential losses.
