Deficit Coverage Mechanism
A deficit coverage mechanism is a protocol-level system designed to absorb losses when a trading platform or decentralized exchange faces a shortfall in collateral. In derivatives trading, this often occurs when a counterparty is liquidated, but their collateral is insufficient to cover the losses before the position is closed.
The mechanism acts as a financial buffer to prevent systemic collapse and protect solvent participants. It is often funded by an insurance fund, which accumulates fees from trading activity, or through socialized losses among liquidity providers.
By isolating these risks, the mechanism ensures the integrity of the order book and maintains confidence in the platform during high volatility. It is a critical component of risk management in under-collateralized or high-leverage environments.
