Portfolio margin is a risk-based methodology for calculating margin requirements that considers the overall risk profile of a trader’s positions. Instead of calculating margin for each individual position separately, this approach assesses the net risk across correlated assets and derivatives within the portfolio. The calculation typically involves stress testing the portfolio against various market scenarios to determine potential losses.
Efficiency
The primary benefit of portfolio margin is enhanced capital efficiency for traders with hedged positions. By recognizing offsetting risks between long and short positions, the system reduces the total margin required compared to standard margin calculations. This allows traders to deploy capital more effectively and increase their leverage within defined risk parameters.
Risk
While portfolio margin improves capital efficiency, it requires sophisticated risk management systems to accurately assess potential losses under extreme market conditions. The calculation relies on assumptions about correlations between assets, which can break down during periods of high volatility. In cryptocurrency markets, where correlations can shift rapidly, accurate risk assessment under portfolio margin is critical.
