The collateralization ratio is a key metric in decentralized finance and derivatives trading, representing the relationship between the value of a user’s collateral and the value of their outstanding debt or leveraged position. It is calculated by dividing the total value of the collateral by the total value of the borrowed assets. A ratio above 100% indicates overcollateralization, which is standard practice in many DeFi protocols to ensure loan security.
Risk
This ratio serves as a primary indicator of risk for both the borrower and the lending protocol. A higher collateralization ratio signifies a healthier position with a larger buffer against adverse price movements in the collateral asset. Conversely, as the ratio approaches the minimum required threshold, the risk of liquidation increases significantly.
Liquidation
The collateralization ratio directly determines the liquidation threshold. When the ratio falls below a predefined minimum level, typically due to a decline in the collateral’s value, the protocol automatically liquidates the collateral to repay the outstanding debt. This automated process protects the solvency of the lending pool and prevents systemic risk.
