## Cross Margin Contagion

Cross margin contagion is the risk that a loss in one leveraged position or sub-account propagates through a portfolio, potentially leading to the liquidation of unrelated, healthy positions. In cross-margin systems, collateral is shared across multiple positions to increase capital efficiency, but this design also creates a single point of failure for the account.

If a major drop in one asset causes a margin call, the protocol may automatically liquidate other positions to satisfy the margin requirement, even if those positions are profitable or stable. This creates a domino effect where a localized market shock can lead to the total depletion of an account's collateral.

For traders, understanding this risk is essential for portfolio management and avoiding unnecessary losses. Protocols must balance the benefits of capital efficiency with the risks of systemic account failure to ensure user protection.

It represents a complex interaction between risk management and leverage.
