Market Liquidity Drain

A market liquidity drain happens when the volume of buy and sell orders in the order book diminishes significantly, making it difficult to execute large trades without causing substantial price slippage. In cryptocurrency markets, this often occurs during periods of extreme uncertainty or when market makers withdraw their quotes to protect against volatility.

When liquidity dries up, the market becomes fragile, as even small trades can trigger outsized price swings. This phenomenon is a critical component of systemic risk, as it limits the ability of traders to exit positions during a downturn.

It reflects the underlying microstructure where the cost of immediate execution increases sharply, punishing those who require quick exits.
