Collateral Stack Contagion

Definition

Collateral stack contagion describes a systemic risk phenomenon in decentralized finance where the failure of a single underlying asset triggers a cascade of liquidations across interconnected derivative protocols. When traders utilize the same token as margin for multiple leveraged positions, price volatility in that specific asset initiates a self-reinforcing feedback loop. This structural dependency forces automated liquidators to sell positions simultaneously, which further suppresses market prices and depletes collateral buffers across the ecosystem.
