Over-Collateralization Requirements
Over-collateralization Requirements are the rules that mandate users to deposit more value in collateral than the amount of the debt or derivative exposure they take on. This requirement is the primary defense against price volatility in decentralized finance.
By ensuring that the value of the collateral always exceeds the debt, the protocol can withstand significant market drops without becoming insolvent. The specific ratio required is determined by the volatility of the collateral asset; more volatile assets require higher collateralization ratios to provide a sufficient buffer.
This approach ensures that even if the collateral loses value, the protocol can still recover the debt through liquidation. While it increases the security of the system, it also limits capital efficiency, as users cannot use their full asset value for trading.
Balancing security and capital efficiency is a constant challenge for protocol architects who must decide the optimal collateralization levels for different assets.
