## Portfolio Margin Models

Portfolio margin models are sophisticated risk management frameworks that calculate margin requirements based on the total risk of a trader's entire portfolio rather than treating each position in isolation. By considering the correlations between different assets and the potential for offsetting gains and losses, these models provide a more accurate assessment of the actual risk exposure.

This approach allows for greater capital efficiency, as traders can effectively hedge their positions without being penalized by rigid, account-level margin rules. Portfolio margin is increasingly common in professional and institutional trading, where it enables more complex strategies.

However, it requires robust mathematical modeling and real-time monitoring to ensure that the risk assessment remains valid as market conditions change.
