Collateral Rehypothecation Limits

Collateral rehypothecation limits define the extent to which an intermediary, such as an exchange or lending protocol, can reuse a user's collateral for its own purposes or to support other transactions. While rehypothecation can increase market liquidity, it also introduces significant counterparty and systems risk, as the original collateral may become unavailable during a liquidity crisis.

Strict limits are placed on this practice to ensure that users can always reclaim their assets and that the protocol remains solvent. In decentralized finance, these limits are often encoded directly into smart contracts to prevent the over-extension of capital.

Understanding these limits is crucial for users evaluating the safety of lending and derivative platforms. Excessive rehypothecation is a known contributor to historical financial contagion events.
