Abstract :Since its first introduction as a primary policy goal by a big central bank, financial stability has received much interest as a distinct matter, separate from price stability and the efficient functioning of the financial sectors. Accordingly, different financial analysts and scholars in the financial system have tried to unravel the complexity of financial stability and have conducted theoretical and empirical research at different levels. This study aims to reveal the internal factors affecting the financial stability of participation banks in Turkey. Therefore, we consider the data of 6 participation banks for the 2019Q1-2023Q1 period. Moreover, we assess the stability of participation banks with the Z-score. As a result of the analyses with the Driscoll &Kraay robust standard errors estimator, firstly, we found a negative relationship between risk-weighted and non-risk-weighted capital ratios and bank stability. Secondly, we concluded that while there is a negative relationship between bank stability and bank size, there is a positive relationship between cost-to-income ratio, loan ratio and collected funds ratio and bank stability. Finally, we observed a negative relationship between asset and fund diversifications and bank stability; in contrast, there is a positive relationship between income diversification and bank stability. The results of the research state that the factors affecting bank stability from most to least are income diversification, fund and asset diversifications, collected funds ratio, non-risk weighted capital ratio, cost-to-income ratio, loan ratio, risk-weighted capital ratio and bank size, respectively. The research results also indicate that participation banks must improve their management efficiency, credit, collected fund and income diversification levels to support their sustainable financial stability and soundness.
