Τhis study investigates the existence of causality between the returns of European Banks and market indices. The determination of the causality is done by using contemporary econometric models, specifically by using Vector Autoregressive models (VAR models), Granger causality and impulse response functions. The banks chosen are from countries that are members of the European Union; one categorized as large cap and one as small cap. Regarding the U.K. and Spain equities, the empirical results of the study indicate that for all the cases examined, the indices, FTSE 100 and Ibex 35 respectively, do not affect the returns of the equities. On the other hand, in France and Italy is proven that the indices CAC 40 and FTSEMIB affect the small cap equities returns.
