Default Cascades

Default cascades refer to a systemic risk phenomenon in financial markets where the failure of one participant to meet margin requirements triggers a chain reaction of liquidations. In the context of cryptocurrency and derivatives, this often occurs when a large position is forcibly closed, driving asset prices down and triggering further margin calls for other participants.

This cycle continues as the price drop impacts more leveraged accounts, potentially leading to a market-wide liquidity crunch. Protocols attempt to mitigate this through insurance funds and circuit breakers.

Understanding this is critical for assessing the stability of decentralized finance platforms. It represents the domino effect inherent in highly leveraged interconnected systems.
