Rehypothecation Risks
Rehypothecation Risks arise when collateral is used multiple times to secure different financial obligations. In traditional finance, this is common in prime brokerage, but in decentralized finance, it happens when a protocol uses deposited assets to provide liquidity or lend to other users.
While this increases capital efficiency, it creates a chain of dependencies where a failure at one point can lead to a systemic collapse. If the original collateral is needed back by the depositor, but it is tied up in other obligations, the protocol may face a liquidity crisis.
This risk is often opaque to the end user, making it difficult to assess the true exposure of a protocol. Managing rehypothecation is essential for maintaining systemic stability in highly interconnected DeFi environments.
