Collateral Haircuts
Collateral haircuts are the percentage difference between the market value of an asset and the amount of credit that can be borrowed against it. This safety buffer is designed to protect lenders against sudden drops in the value of the collateral.
For example, if an asset has a 20 percent haircut, a borrower can only borrow 80 percent of its current market value. In volatile crypto markets, these haircuts are often much higher than in traditional finance to account for the higher risk of price swings.
If the value of the collateral falls below the loan value plus the haircut, the position becomes under-collateralized and subject to liquidation. Properly setting these haircuts is a balancing act between encouraging borrowing and maintaining protocol solvency.
It is a fundamental tool for managing credit risk in decentralized lending markets.
