Market Liquidity Crushing
Market liquidity crushing is a scenario where the availability of buy and sell orders vanishes during a period of extreme market stress. This makes it impossible for traders to exit positions without incurring massive slippage or for protocols to execute liquidations efficiently.
This phenomenon is often the result of market participants retreating in fear, leading to a complete breakdown in the order book. When liquidity is crushed, even small trades can cause massive price swings, further exacerbating the crisis.
It is a critical component of market crashes, as it removes the "shock absorbers" that usually keep prices stable. In crypto derivatives, this is particularly dangerous because the automated nature of liquidations can lead to a feedback loop of selling into an empty market.
It is the ultimate test of a protocol's robustness.
