Abstract

The Global Financial Crisis triggered a revision of the VaR based Basel II market risk framework to address extreme events. The revised VaR methodology remains unchanged under Basel III, however ongoing studies to evaluate VaR continue in academia and by the Basel Committee. In this paper, we assess VaR models for Australian banks over the past ten years and provide statistical evidence of their effectiveness. Results indicate that one year parametric and historical models produce better measures of VaR than models with longer time frames. VaR estimates produced using Monte Carlo simulations show very low percentage of violations but higher level of violations. VaR estimates produced by the ARMA GARCH model show relatively high percentage of violations, however, the level of violations is quite low. Our findings shed light on the rationale and design of the revised Basel II VaR methodology which has also been adopted under Basel III.
