Market Maker Withdrawal
Market maker withdrawal occurs when entities providing liquidity pull their buy and sell orders from the order book, typically during periods of extreme volatility or uncertainty. Because market makers earn their profit from the spread and rely on volume, they face high risk when price movements are erratic or when they cannot accurately price the risk of their positions.
When they exit the market, liquidity depth vanishes, causing price volatility to explode. This creates a vacuum where even small trades result in massive price swings, leading to the pricing discontinuities mentioned previously.
This behavior is rational from the perspective of the market maker, who seeks to avoid adverse selection, but it is catastrophic for the overall health of the trading venue. Understanding the conditions that trigger this withdrawal is key to predicting market crashes and designing more resilient liquidity structures.
