Currency Risk Modelling by GARCH-Copula Model

Popis výsledku v původním jazyce

Time series modelling and subsequent risk estimation is difficult and important activity of any financial institution. Financial time series are characterized by volatility clustering and heavy-tailed distribution of returns. Both these characteristics have a great influence for risk estimation. Especially when modelling more-dimensional probability distribution, shocks in terms of extreme losses (or returns) in particular risk drivers are usually more correlated than the losses (returns) closer to themean. In this paper we focus on GARCH-copula models. The copula functions are the tool which allows us to model the dependence among individual risk drivers. On the other hand, GARCH model allows depicting the volatility clustering. Concretely, GARCH model with Student distribution of innovations and various copula functions are assumed in the paper. These joined models are backtested on chosen dataset and VaR exceedances (i.e. their quantity and distribution in time) are statistically t
