Value at Risk (VaR) has achieved a pre-eminent place when quantifyin portfolio market risk. VaR calculation can be carried out using several models, with statistical likelihood being the key feature. In this paper we propose a new model for VaR estimation, namely the ARCH factor methodology. We apply this methodology on a set of foreign exchange risk exposed portfolios and test the previously assumed statistical confidence level. Furthermore, we compare our results with those obtained through J.P. Morgan’s Riskmetrics methodology utilisation.
