Collateral Factor Calibration
Collateral Factor Calibration is the systematic process of determining the maximum percentage of an asset's market value that a lending protocol will accept as collateral for a loan. It serves as a primary risk management tool to protect the protocol from insolvency during periods of high market volatility.
If an asset is highly liquid and stable, it receives a higher collateral factor, allowing users to borrow more against it. Conversely, volatile or illiquid assets receive lower factors to mitigate the risk of a price crash exceeding the value of the collateral.
Protocols must continuously adjust these factors based on real-time data to ensure that liquidation mechanisms remain effective. By setting these parameters, a protocol balances capital efficiency for borrowers with the safety of the lender pool.
Proper calibration prevents bad debt accumulation by ensuring that the protocol can always liquidate undercollateralized positions before the debt exceeds the collateral value. It is a dynamic process that accounts for market microstructure and liquidity depth.
Ultimately, it defines the leverage limits within decentralized finance ecosystems.
