Cascading Liquidation Risk
Cascading Liquidation Risk is the danger that a series of automated liquidations on a lending protocol will cause a sharp, localized drop in asset prices, triggering further liquidations. In decentralized finance, lending protocols automatically sell collateral when a user's health factor drops below a specific threshold.
If a large borrower is liquidated, the sudden sell pressure can drive the asset price down further. This lower price then causes more users to fall below their liquidation thresholds, creating a feedback loop.
This process can rapidly deplete liquidity and leave protocols with bad debt if the market moves faster than the automated engines can clear positions. It is a critical component of systemic risk in cryptocurrency derivatives, as it links protocol-specific health to broader market volatility.
Risk managers must model these scenarios to ensure collateral requirements are sufficient during extreme market stress. Without proper buffers, these cascades can lead to total protocol insolvency.
