Collateral Interdependency
Collateral interdependency refers to the systemic risk arising when multiple protocols rely on the same assets as collateral for loans or derivatives. If the value of that common collateral asset drops significantly, it can trigger simultaneous margin calls and liquidations across the entire ecosystem.
This creates a domino effect, as the forced selling of the collateral further depresses its price, leading to more liquidations. In decentralized finance, this is a significant concern because many protocols use the same popular tokens, like ETH or stablecoins, as collateral.
The lack of centralized oversight means that these risks can build up undetected until a market shock occurs. Protecting against this requires diversifying collateral types, setting conservative loan-to-value ratios, and implementing stress testing for protocol dependencies.
It is a critical aspect of understanding the systemic fragility of the crypto market.
