The SPAN (Standard Portfolio Analysis of Risk) model is a portfolio-based risk management system used by clearinghouses to calculate margin requirements for derivatives positions. It assesses potential losses across a range of predefined market scenarios, including changes in price and volatility. The model provides a comprehensive view of portfolio risk by considering correlations between different assets and derivatives.
Calculation
SPAN calculation involves determining the total margin required for a portfolio by summing the risk components of individual positions and applying offsets for correlated assets. This methodology moves beyond simple position-based margin requirements to provide a more accurate assessment of overall portfolio risk. The model calculates a risk array for each product, representing potential gains and losses under various market conditions.
Application
While originally developed for traditional financial markets, the principles of the SPAN model are highly relevant to cryptocurrency derivatives. Decentralized exchanges and clearing protocols can adapt SPAN-like methodologies to calculate dynamic margin requirements for complex crypto derivatives portfolios. This approach allows for more efficient capital utilization while maintaining adequate collateral to cover potential losses.
