Financial market development and bank deposits

Abstract

This paper studies the effects of financial market development on bank deposits in a cross-country setting. Our empirical evidence shows that investors in developed and developing economies engage with financial markets differently, leading to varying impacts on bank deposits. For instance, in financially developed economies, financial markets typically complement the banking sector by facilitating deposit growth. Conversely, in financially developing economies, financial markets and banks often compete for deposits, thereby constraining bank deposits growth. This dynamic, however, is shaped by country-specific factors such as market concentration and the level of deposit insurance. Moreover, we find that financial market development increases per capita savings, which in turn strengthens bank deposit growth. These findings remain consistent across a range of model specifications and robustness checks.
