Liquidation Deficit

A liquidation deficit occurs when a position is liquidated at a price lower than the bankruptcy price, resulting in a loss that exceeds the trader's initial margin. This deficit represents bad debt that must be absorbed by the exchange's insurance fund or, in extreme cases, socialized across other traders.

The occurrence of a deficit indicates that the liquidation engine was unable to close the position in time to protect the margin. Factors contributing to this include extreme market illiquidity, rapid price gaps, and high volatility.

Minimizing liquidation deficits is a primary goal of risk management for any derivatives platform. Frequent deficits can erode the insurance fund and threaten the long-term stability of the protocol.

It is a key indicator of the effectiveness of a platform's risk engine.
