Depeg
Also called: de-peg · stablecoin depeg · losing the peg
Definition
A depeg is when a stablecoin or pegged token trades meaningfully away from the value it is designed to track, such as a dollar stablecoin falling below 1 USD.
How depeg works
Stablecoins like USDT and USDC aim to stay at 1 US dollar. Small moves such as 0.999 or 1.001 are normal market noise. A depeg means a larger or longer gap, usually because holders doubt the backing, redemptions are paused, or liquidity on trading venues dries up.
Causes differ by design. A fiat-backed coin can wobble if part of its reserves is stuck at a troubled bank. A crypto-backed coin can slip if its collateral crashes faster than liquidations can keep up. An algorithmic coin can collapse entirely when confidence breaks, because nothing hard backs it. Pegged tokens such as liquid staking tokens can also trade at a discount when many holders rush to exit at once.
For traders, a depeg matters in two ways: the stablecoin you count as cash may suddenly be worth less, and any position or loan priced in that coin can be repriced. Exchanges may also pause trading pairs, change margin rules or adjust collateral value during a depeg, and each one handles this differently.
Example
Suppose you hold 10,000 units of a dollar stablecoin and news breaks that part of its reserves is frozen. The market price drops to 0.92 USD. On paper your balance is now worth 9,200 USD, a loss of 800 USD. If the issuer later restores full redemptions and the price returns to 1.00, the loss disappears. If it settles at 0.95 instead, the 500 USD gap becomes permanent for anyone who sold or still holds.
Common mistakes
- Treating every stablecoin as equally safe without checking what backs it and who can redeem it.
- Panic selling into a thin market during a brief depeg and locking in a loss that would have recovered.
- Buying a depegged coin as a sure bargain without understanding whether the backing can actually cover redemptions.

FAQ
Can USDT or USDC depeg?
Yes, any stablecoin can trade below its target. USDC briefly fell well below 1 USD in March 2023 when part of its reserves sat at a failed US bank, then recovered after the funds were confirmed safe.
Does a depeg always mean the stablecoin is dead?
No. Many depegs are short and recover once redemptions work again. A permanent depeg usually means the backing is insufficient or the design has failed.
