Determination of a margin requirement associated with a plurality of financial instruments within a portfolio is disclosed for analyzing the portfolio including determining a first and second time-series of returns for the financial instruments, where the second time-series occurs after the first, and calculating the correlation between the first and second time-series of returns. The system and method further implement calculating residuals and volatilities for the financial instruments within the portfolio as a function of the first time-series of returns, calculating a correlation matrix and degrees-of-freedom utilized to simulate standardized residuals for each of the financial instruments within the portfolio, generating simulated returns as a function of the simulated standardized residuals and the returns, generating a spread distribution for the portfolio, wherein the portfolio is repriced as a function of the simulated returns, and calculating a margin risk based on a risk percentile associated with the spread distribution.
