Collateral Haircut
A Collateral Haircut is a percentage reduction applied to the value of an asset when it is used as collateral for a loan or a margin position. This discount accounts for the risk that the asset's value might decline, making it less effective at covering potential losses.
In cryptocurrency, assets with higher volatility or lower liquidity receive larger haircuts. For example, a stablecoin might have a small haircut, while a volatile altcoin would have a significant one.
The haircut ensures that the lender or exchange is protected even if the collateral value drops sharply. This is a fundamental component of decentralized finance lending protocols and centralized margin engines.
By applying these discounts, protocols maintain a buffer that protects the system from price shocks. Traders must be aware of these adjustments, as they directly impact their available borrowing power and liquidation risk.
It is a prudent measure to ensure the long-term solvency of the collateral pool.
