Abstract

The purpose of this paper is to empirically examine the effects of capital and liquidity on bank stability as well as the existence of a potential complementary or substitute relationship between both dimensions to explain bank stability. We use a sample of 16,061 banks from 27 countries during the period 2013-2023. Our results show that both capital and liquidity increase bank stability. However, the joint interactive effect presents a negative coefficient indicating the existence of a potential substitution effect between both variables. We also provide evidence on market power acting as a potential mechanism explaining the baseline relationships. Furthermore, the results seem to be modulated by specific bank- and country-level factors. JEL Classification: G20, G21, G28, K00
