Cascading Liquidation Mechanism

A Cascading Liquidation Mechanism is a systemic event in decentralized finance where the forced sale of collateral to cover margin requirements triggers further price drops, leading to subsequent liquidations. When a cryptocurrency price falls rapidly, it hits the liquidation thresholds of multiple leveraged positions simultaneously.

The protocol then automatically sells this collateral to repay debt, which increases selling pressure on the market. This added supply drives the price down further, triggering the liquidation of even more positions.

This cycle can continue until the protocol's liquidity pool is depleted or the market finds a new floor. This phenomenon is a significant concern for systemic risk and contagion in crypto markets.

Protocols often use circuit breakers or specialized liquidation engines to dampen these effects.
