Abstract

We propose a novel technique to measure three aspects of banks' sectoral concentration that feature prominently in episodes of intensi fied (systemic) bank risk: specialization (capturing overexposures), differentiation (capturing indirect connectedness), and fi nancial sector exposure (capturing direct connectedness) and show external validity for these measures. We fi nd that both individual and systemic bank risk decrease withspecialization. Indirect connectedness of banks is particularly (and negatively) related to individual bank risk, whereas direct connectedness of banks is particularly (and positively) related to systemic bank risk. These fi ndings inform the theoretical and policy debate on the relationship between sectoral concentration and banks' stability.

Keywords: bank concentration, sectoral specialization, differentiation, bank risk, systemic stability, factor model
