30-Second Stablecoin Depegs Wreak Devastating Consequences

A stablecoin depeg is often seen as a gradual loss of confidence in the asset, with reserves being questioned and redemptions spiking over hours or days. However, this narrative does not hold true for short-term depegs that last mere seconds to minutes.

In these cases, the damage caused by the depeg operates on a different timescale than the narratives written about it afterward. A stablecoin depeg lasting fewer than 60 seconds can trigger hundreds of millions of dollars in DeFi liquidations because lending protocols rely on price oracles that update on fixed intervals, not in real-time.

The March 2023 USDC depeg caused by Silicon Valley Bank's failure is a prime example. Approximately $2.1 billion in DeFi liquidations occurred within the first four hours, with the largest single liquidation exceeding $52 million on Aave v2.
