Τhis thesis presents the concepts of the Banking System , the Risk and its calculation using the Value At Risk methodology (VAR). This method calculates a number that expresses the maximum expected loss for a given confidence level and given horizon. Specifically, the VAR is calculated by combining time series analysis (ARIMA) and generalized autoregressive conditional heteroskedasticity models (GARCH). This method is applied to the equity returns of specific European banks trying spoting variations in results, variations due to different economic sizes of the economies in which the under study banks are located.
