A system and computer-implemented method for determining a margin requirement associated with a plurality of financial instruments within a portfolio is disclosed. The system and method implement steps and procedures for analyzing the portfolio including the plurality of financial instruments where analyzing further includes determining a first time-series of returns for the plurality of financial instruments, determining a second time-series of returns for the plurality of financial instruments where the second time-series occurs after the first time-series, and calculating the correlation between the first time-series of returns and the second time-series of returns. The system and method implement further steps and procedures for calculating residuals and volatilities for the plurality of 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 plurality of 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.
