Futures margin modeling system
First Claim
1. A clearinghouse computing device configured to generate a margin requirement for a portfolio of financial products, comprising:
- a processor; and
a non-transitory memory device storing instructions that, when executed by the processor, cause the clearinghouse computing device to;
(a) generate, by a time series generator of a clearinghouse computer system, continuous time series of pricing information corresponding to a financial product held in a portfolio, the continuous time series of pricing information comprising a plurality of dimensions each corresponding to a factor contributing to dynamics of the continuous time series;
(b) calculate, by a dimension reduction module of the clearinghouse computer system, a dimension-reduced projection of the continuous time series of pricing information based on a principle component analysis (PCA) technique the dimension reduced projection using less than all of the factors to represent the dynamics of the continuous time series;
(c) calculate, by a variance scaling module of the clearinghouse computer system, a volatility normalization of the dimension reduced projection by performing volatility normalization of scores and volatility normalization of error terms of the dimension reduced projection of the continuous time series of pricing information to produce a plurality of curves;
(d) determine, by a covariance scaling module of the clearinghouse computer system, an inter-curve and intra-curve correlation between the plurality of curves; and
(e) generate, by a value at risk estimation module of the clearinghouse computer system, an estimated value at risk based on the inter-curve and intra-curve correlation between the plurality of curves.

Abstract
A clearinghouse computing device may be configured to generate a margin requirement for a portfolio of financial products and may include a processor to process instructions that cause the clearinghouse computing device to retrieve a plurality of pricing records from a historical pricing database, process the plurality of pricing records to generate rolling time series pricing records for at least one financial product having a plurality of dimensions, reduce the number of dimensions from a starting dimension to a reduced dimension, perform variance scaling and correlation scaling on the reduced dimension rolling time series pricing records, and generate a margin requirement based on a value-at-risk calculation.
