Cross-Margin Account Risks

Cross-margin account risks arise when a single pool of collateral is used to back multiple different derivative positions. If one position suffers a significant loss, it can draw down the collateral available for all other positions, potentially leading to a cascading liquidation of the entire account.

While cross-margin systems offer greater capital efficiency for the trader, they significantly increase the complexity of risk management. A trader might believe they are hedged, but a sudden move in one asset could wipe out their collateral, causing the liquidation of healthy positions.

This structure requires sophisticated risk modeling and strict limits to prevent account-wide failures during high volatility.
