Liquidity Crunch
A Liquidity Crunch in decentralized finance occurs when a lending pool lacks sufficient available assets to meet withdrawal demands from lenders. This situation often arises when a large percentage of the pool is locked in loans or when market volatility causes a mass exodus of capital.
When utilization ratios approach one hundred percent, the protocol may be unable to honor withdrawal requests, leading to a loss of confidence. Interest rate models attempt to mitigate this by raising rates to incentivize repayment, but if the incentives fail, the protocol may face a systemic failure.
This risk highlights the importance of over-collateralization and robust parameter tuning. It is a classic example of a liquidity risk where the asset is technically solvent but inaccessible.
