System and method for asymmetric offsets in a risk management system
First Claim
1. A computer implemented method of analyzing risk in a portfolio, the portfolio including at least two of a plurality of products traded on an exchange, the method comprising:
- determining, in a computer, a correlation between first and second products of the at least two products, the first product being associated with a first margin requirement and the second product being associated with a second margin requirement;
computing, by the computer, a first risk offset based on the correlation, the first risk offset comprising an adjustment to the first margin requirement;
assigning, by the computer, the first risk offset to the first product;
computing, by the computer, a second risk offset based on the correlation and a compensating factor, the second risk offset being different from the first risk offset, the second risk offset comprising an adjustment to the second margin requirement;
assigning, by the computer, the second risk offset to the second product; and
computing, by the computer, a combined margin requirement for the first and second products as the sum of the first margin requirement for the first product adjusted as a function of the first risk offset and a the second margin requirement for the second product adjusted as a function of the second risk offset.

Abstract
A system and method for using asymmetrical offsets for products in a risk management analysis system are disclosed. Conventional systems assign symmetrical offsets for products, that is, if two products have an 80% correlation they each would be assigned an offset of 80% with respect to each other. However, it is desirable to allow for asymmetrical offsets. In the disclosed system and method, when two products have a correlation of 80%, one may be assigned an offset of 75% and the other may be assigned an offset of 80%. There are many reasons to vary the offset between the products. The varying offset may reflect an asymmetry in the risk in one of the products, such as being traded in an illiquid market or in a less desirable venue. The varying offset may correct for an imbalance in spread credits due to special charges from intra spreading.

6. A system for analyzing risk in a portfolio, the portfolio including at least two of a plurality of products traded on an exchange, the system comprising:
-
a processor configured to determine a correlation between first and second products of the at least two products, the first product being associated with a first margin requirement and the second product being associated with a second margin requirement; the processor being further configured to compute a first risk offset based on the correlation, the first risk offset comprising an adjustment to the first margin requirement, and assign the first risk offset to the first product, the processor being further configured to compute a second risk offset based on the correlation and a compensating factor, the second risk offset being different from the first risk offset, the second risk offset comprising an adjustment to the second margin requirement, and assign the second risk offset to the second product; and the processor being further configured to compute a risk assessment of the portfolio based on at least the first and second risk offsets and further compute a combined margin requirement for the first and second products as the sum of a the first margin requirement for the first product adjusted as a function of the first risk offset and a the second margin requirement for the second product adjusted as a function of the second risk offset. - View Dependent Claims (7, 8, 9, 10)
