Deleveraging Mechanism
A deleveraging mechanism is a procedure used by an exchange to reduce the total leverage in the system during extreme market events. If the insurance fund is insufficient to cover losses from a massive liquidation event, the exchange may implement auto-deleveraging.
This process forces profitable traders to close their positions against the bankrupt accounts to neutralize the risk. It is considered a measure of last resort because it disrupts the positions of traders who are not directly involved in the insolvency.
By spreading the risk, the exchange prevents a total system collapse, although it can be controversial among participants. Understanding how an exchange handles deleveraging is crucial for risk assessment when choosing a trading venue.
