Collateral Correlation Risks
Collateral correlation risks occur when the assets used as collateral in a protocol are highly correlated, meaning they tend to move in the same direction during market stress. If a protocol accepts a variety of assets that all crash simultaneously during a market-wide downturn, the system's total collateral value will evaporate, leaving it unable to cover its liabilities.
This risk is often underestimated because, in normal market conditions, the assets might seem diverse. However, in a crisis, liquidity often flees to cash or stablecoins, causing all other digital assets to drop together.
Diversifying collateral with non-correlated assets, such as stablecoins or real-world assets, is a critical strategy for mitigating the impact of these systemic correlation risks.
