A Comparison of Conditional and Unconditional VaR Models

Krzysztof Echaust , Małgorzata Just


: This paper presents the empirical research on comparison of two different approaches for Value at Risk (VaR) measurement. The research objective is to compare the accuracy of out-of-sample VaR forecasts between conditional and unconditional models. We examine four unconditional models: Gaussian, alpha-stable, Normal Inverse Gaussian (NIG) and Generalized Pareto (GP) distributions and four conditional models: Generalized Autoregressive Conditional Heteroskedasticity (GARCH) model with Gaussian and Student’s t innovations, Exponentially Weighted Moving Average (EWMA) and conditional Extreme Value Theory (GARCH-EVT) approach. Calculations are performed on the basis of 5 world indices, 4 exchange rates and 4 commodity futures and the results are presented for left and right distribution tails. Backtesting methods indicate the GARCH-EVT as the model that outperforms all others.
