Cross-Margin Risk Aggregation

Cross-margin risk aggregation is a system that allows a trader to use the collateral from one position to support another, rather than siloing collateral for each individual trade. This increases capital efficiency, allowing traders to manage larger positions with less total capital.

However, it also means that a loss in one position can impact the health of the entire account, potentially leading to the liquidation of all positions if the total collateral ratio drops too low. Aggregating risk requires sophisticated monitoring to ensure that the total account remains within safe parameters.

This is a common feature in both centralized and decentralized exchanges, but it requires careful implementation to prevent unintended consequences during high market volatility. It represents a balance between maximizing trader flexibility and managing systemic exposure.
