Shared Collateral Vulnerability

Shared collateral vulnerability is the risk that occurs when the same asset is used as collateral across multiple, often unrelated, protocols. If a price crash occurs, the asset's value drops everywhere simultaneously, triggering liquidations on every platform where it is used.

This synchronizes the selling pressure, making it much harder for the market to absorb the volume. Because these protocols are often unaware of each other's positions, the total leverage on the asset can be much higher than any individual protocol realizes.

This creates a hidden layer of systemic risk that is difficult to monitor or mitigate. It highlights the need for better risk transparency in the decentralized finance space.
