Over-collateralized lending requires borrowers to deposit assets with a value greater than the amount of the loan they receive. This mechanism is fundamental to decentralized finance protocols, where loans are issued without traditional credit checks or intermediaries. The excess collateral serves as a buffer against price volatility of the underlying assets.
Risk
The primary purpose of over-collateralization is to mitigate counterparty risk and ensure the solvency of the lending protocol. By requiring a collateral ratio significantly above 100%, the protocol protects lenders from losses in the event of a borrower default. This structure is essential for maintaining stability in volatile cryptocurrency markets where asset prices can fluctuate rapidly.
Liquidation
If the value of the collateral falls below a predefined threshold, the protocol automatically liquidates the collateral to repay the loan. This automated liquidation process prevents the loan from becoming undercollateralized and protects the integrity of the lending pool. The over-collateralization ratio determines the buffer size and influences the frequency of liquidations during market downturns.
Meaning ⎊ Decentralized Capital Efficiency maximizes liquidity utility by enabling simultaneous, risk-optimized collateral deployment across derivative protocols.
