Liquidation Cascade

Definition

A liquidation cascade is a sequence of forced selling events that can occur in leveraged trading environments, particularly within decentralized finance (DeFi) protocols. When the value of collateral assets falls below a certain threshold, automated liquidation processes are triggered, selling the collateral to repay debt. If this selling pressure drives asset prices down further, it can trigger more liquidations, creating a self-reinforcing downward spiral. This phenomenon can lead to rapid and substantial price declines and significant market instability.
