Liquidation Velocity
Liquidation Velocity measures the speed and intensity at which positions are closed by a protocol's liquidation engine during a market event. High liquidation velocity can be beneficial in ensuring the protocol remains solvent, but it can also contribute to market instability if it happens too quickly.
When many liquidations occur in a very short timeframe, it creates a massive supply shock that the market may not be able to absorb. This leads to extreme price volatility and can trigger further liquidations, creating a cycle of instability.
The challenge for protocol designers is to balance the need for rapid solvency protection with the need to minimize market impact. Advanced liquidation mechanisms, such as Dutch auctions or batch liquidations, are used to manage this velocity.
