Clawback
A clawback is a mechanism where an exchange recovers losses from profitable traders to cover the deficit created by a bankrupt trader whose collateral was insufficient. This typically happens when the insurance fund is exhausted during a massive market crash.
By taking a percentage of the profits from successful traders, the exchange ensures that the counterparty to the bankrupt trader still receives their full payout. Clawbacks are generally considered a failure of the exchange's risk management, as they socialize losses among traders who did not take on the bad risk.
This creates significant frustration and can lead to a mass exodus of liquidity from the platform. To avoid this, exchanges strive to maintain robust insurance funds and strict liquidation thresholds.
The possibility of a clawback is a major risk factor that professional traders monitor when selecting a trading venue. It represents the ultimate breakdown of individual account isolation in a derivatives market.
