margin attribution models

With any approach to margin, deciding how trades contribute to total legal entity IM needs careful thought. Trades offset each other when grouped in strategies or portfolios.  

The way in which your organization is structured may have an effect on margin – a portfolio needs to carry the underlying cost of margin even if it happens to be offset by other trades.

The Marginal Approach

This method derives portfolio margin by calculating the effect of removing a selected portfolio and calculating the change in IM. By subtracting the portfolio, you see the effect of adding the portfolio back into the overall legal agreement IM.

This method determines the amount of margin the portfolio brings to the overall legal agreement. It allows for offsets between the chosen portfolio and the whole legal entity agreement IM.

The Pro-rating Approach

This method comes from another direction and calculates the IM for each portfolio on a standalone basis, then attributes the margin as a ratio of each portfolio contribution to the whole.

Compared to the Marginal approach, this ignores offsets between portfolios, as they are calculated individually and treats each portfolio separately as if they were their own businesses.
