## Margin Engine Default

A margin engine default occurs when the automated system responsible for monitoring collateral and enforcing margin requirements fails to prevent a loss. This usually happens when market volatility moves faster than the engine can liquidate positions, leading to an account balance that drops below zero.

When an account goes bankrupt, the exchange or protocol must absorb the loss, often drawing from an insurance fund or socialized loss mechanism. If these buffers are insufficient, the entire system faces a systemic risk of insolvency.

Margin engines must be precisely calibrated to balance the speed of liquidation with the need to protect traders from unnecessary closures. A failure here represents a critical breakdown in the technical architecture of derivative platforms.
