Liquidation Shortfall
A liquidation shortfall occurs when the value of a borrower's collateral falls below the amount of debt owed, and the protocol is unable to recover the full debt through the liquidation process. This often happens during periods of extreme market volatility where asset prices move faster than the automated liquidation engines can execute sell orders.
When a position is liquidated, the protocol sells the collateral to repay the loan; if the market price drops significantly before the sale completes, a gap emerges between the proceeds and the debt. This gap is the shortfall, which must be covered to maintain the protocol's overall solvency.
Many protocols utilize insurance funds or the protocol solvency buffer to absorb these losses. If the shortfall exceeds available reserves, it may lead to socialized losses among lenders.
Managing this risk requires sophisticated liquidation mechanisms and efficient oracle price updates.
