Perpetual Swap Liquidations

Perpetual swap liquidations occur when a trader's margin balance falls below the maintenance margin requirement, forcing the protocol to automatically close their position. Because perpetual swaps have no expiration date, they rely on a funding rate mechanism to keep the price anchored to the underlying asset.

When a position is liquidated, the protocol sells the collateral to cover the loss, which can introduce significant sell pressure into the market. If many liquidations happen simultaneously, it can lead to a rapid drop in price, triggering even more liquidations.

This creates a liquidation cascade, which is a major source of volatility in crypto derivatives. Exchanges use insurance funds to cover losses that exceed the trader's collateral, helping to stabilize the market during these events.

Managing liquidation risk is a primary concern for both traders and protocol architects.
