Liquidation Spread
The liquidation spread is the difference between the price at which a liquidator purchases the collateral and the current market price of that collateral. This spread acts as a discount for the liquidator, which compensates them for the risk and effort of participating in the auction.
A larger spread provides a greater incentive for liquidators to act quickly, which is beneficial for the protocol during fast-moving market crashes. However, a spread that is too large can also result in excessive losses for the borrower, which might lead to user dissatisfaction.
The optimal spread is a balance between attracting sufficient liquidity and minimizing user impact. It is a critical economic variable that influences the efficiency of the liquidation mechanism.
