Market Maker Retreat
Market maker retreat occurs when liquidity providers withdraw their quotes from the order book due to perceived high risk or extreme volatility. This action is a defensive measure to avoid being picked off by informed traders or caught in a rapidly moving market.
When major market makers retreat, the order book thins out, causing volatility to spike and price discovery to become inefficient. This phenomenon is a primary driver of liquidity black holes and can exacerbate market crashes.
It reflects the strategic interaction between participants in an adversarial environment, where liquidity is only provided when the risk-reward ratio is favorable.
