## Over-Collateralization Buffer

An over-collateralization buffer is a risk management mechanism in decentralized finance where a borrower must deposit assets with a value exceeding the value of the loan they receive. This surplus value acts as a safety cushion to protect the lender or the protocol against sudden drops in the market value of the collateral.

If the value of the collateral falls toward the value of the loan, the buffer helps ensure the position remains solvent. Protocols often set specific collateral ratios that dictate how much extra value must be locked.

This mechanism is essential in automated lending platforms where there is no central counterparty to guarantee the debt. By requiring this buffer, the system can automatically liquidate the collateral if it falls below a critical threshold to repay the lender.

It is a fundamental tool for mitigating credit risk in trustless environments. Without this buffer, volatility in crypto assets would frequently lead to under-collateralized loans and systemic protocol failure.

It effectively shifts the risk of price volatility from the lender to the borrower.
