Cross-Margin Liquidation Cascades
Cross-margin liquidation cascades happen when the liquidation of a single asset on one platform triggers a chain reaction that forces the sale of other assets across the entire portfolio. In highly leveraged environments, a sharp drop in the price of one collateral asset can push the total account value below the required maintenance margin threshold.
This forces the protocol to sell off assets to recover debt, which further depresses prices and triggers liquidations in other linked positions or platforms. Because crypto markets are highly correlated, this effect can move quickly through the ecosystem.
It creates a feedback loop where selling pressure creates more selling pressure. Traders caught in this cycle often find their entire portfolio liquidated in seconds.
This risk is a primary driver of sudden flash crashes in digital asset markets. Understanding this requires analyzing the correlation between assets held as collateral.
