Auto Deleveraging Mechanisms
Auto deleveraging is a risk management tool used by some derivatives exchanges to prevent the need for an insurance fund to cover losses from bankrupt accounts. When a position is liquidated and the market is moving too fast for the liquidator to close the position without incurring a loss, the exchange may trigger an auto-deleveraging event.
This involves automatically closing the bankrupt position against the most profitable opposing traders on the platform. Those traders are effectively forced to close their positions at the bankruptcy price of the liquidated account.
While this protects the exchange from insolvency, it can be disruptive for traders who are unexpectedly closed out of profitable positions. It is a feature of market microstructure designed to maintain system stability in extreme conditions.
Traders must be aware of their position's ranking in the auto-deleveraging queue to assess their risk of being closed out by the system.
