Collateral Ratio

Definition

Collateral ratio indicates the value of assets held as security relative to the value of a loan or debt position, typically expressed as a percentage. In decentralized finance, this metric is crucial for lending protocols, where users over-collateralize their loans to mitigate default risk. A higher collateral ratio provides greater security for the lender, while a lower ratio carries increased liquidation risk for the borrower. It functions as a primary risk management tool within crypto lending platforms.
