Cross-Asset Collateral Correlation

Cross-asset collateral correlation is the measure of how different assets move in relation to each other, which significantly impacts the risk of a portfolio. If a protocol accepts multiple assets as collateral, it must account for the fact that these assets may crash simultaneously during a market downturn.

High correlation between collateral assets reduces the diversification benefit and increases the probability of multiple positions hitting their threshold breaches at the same time. Protocols must adjust their risk parameters to account for these correlations to avoid systemic insolvency.

Ignoring this leads to a false sense of security and heightened vulnerability to market-wide contagion.
