Investigation the Effect of Credit Risk on Financial Stability in the Islamic Banking System

Banks and their volume of financial transactions have a positive effect on the income of companies and the country's economy and paying attention to their stability conditions can create a stable economy. The purpose of this study is to investigate the effect of credit risk on the financial stability of banks listed on the Tehran Securities Exchange. In order to measure the credit risk variable from the research of Zupandis et al. (2017), the Z-score index was used to measure the financial stability variable based on Farhi (2018) and Al-Badri (2015) studies. The generality of this index is due to the fact that it is inversely related to the probability of bankruptcy of a bank. The number of sixteen banks accepted in the Tehran Stock Exchange in the period of six years from 2014 to 2019 were selected as the statistical population of the research. Multivariate regression analysis using mixed data method with fixed effects was used to test the hypotheses. The research results show that credit risk has a significant and adverse effect on the financial stability of banks. In fact, one of the factors that can strongly affect the stability of banks is the credit risk of banks.
