The determinants of bank profitability: empirical evidence from European banking sector

The purpose of this paper is to investigate the relationship between bank-specific characteristics and profitability in European banking sector to find the role of internal factors in achieving high profitability.

A regression analysis is built on an unbalanced panel data set comprising 175 observations of 35 top European banks over the period 2009-2013. To this end, the empirical data are collected from Bankscope and a comprehensive set of internal characteristics is examined.

All the determinant variables included in the model have statistically significant impacts on European banks’ profitability. However, the effects are not uniform across profitability measures. Regression findings reveal that size and capital ratio are significant company-level determinants of bank profitability in Europe, while higher loan loss provisions result in lower profitability levels. Findings also suggest that banks with higher deposits and loans ratio tend to be more profitable but the effects on profitability are statistically insignificant in some cases.

This study has considerable policy implications, as the performance of the European banking sector depends on its efficiency, profitability and competitiveness. In view of these findings, some suggestions may be functional for bank regulatory authorities to intensify and sustain robustness and stability of the banking sector.

The results provide interesting insights into the characteristics and practices of profitable banks in Europe. Few econometric studies have empirically explored the determinants of bank profitability in Europe so far, even though similar studies have been conducted in several developed countries. Therefore, this paper tries to close an important gap in the existing literature improving the understanding of bank profitability in Europe.
