## What is the Model of SPAN Margin Model?

The SPAN (Standard Portfolio Analysis of Risk) margin model is a portfolio-based methodology used by clearing houses to calculate margin requirements for derivatives positions. Unlike simple fixed-rate margin systems, SPAN assesses the overall risk of a portfolio by simulating potential market movements across various scenarios. This approach calculates a single margin requirement that reflects the net risk of all positions.

## What is the Risk of SPAN Margin Model?

The model calculates risk by considering potential losses under different market scenarios, including changes in price and volatility. It accounts for offsets between long and short positions in related instruments, reducing the margin requirement for hedged portfolios. This methodology provides a more accurate assessment of risk exposure compared to calculating margin for each position individually.

## What is the Portfolio of SPAN Margin Model?

The SPAN model calculates margin based on the total risk of a trader's portfolio, rather than individual positions. By recognizing correlations between different assets and derivatives, it promotes capital efficiency for sophisticated traders. This portfolio approach is widely adopted in traditional derivatives markets and is increasingly being adapted for use in cryptocurrency derivatives exchanges.
