Abstract

The purpose of this article was to investigate the relationship between the diversification of banking resources and expenses with systemic risk in the country's banking system. In this regard, the accepted banks in the Tehran Stock Exchange were evaluated. In order to estimate the systemic risk, the criterion of conditional value at risk was used. Also, in order to estimate the impact of diversification of banking resources and expenses on systemic risk, panel data and quantile regression were used for a selection of banks in the country in the period of 2010-2022. The results obtained from this study indicated that the diversification of banking resources and expenses, because it leads to more dependence between financial institutions, as well as a different combination of financial assets, leads to an increase in systemic risk and contagion. It goes to other financial institutions. In the estimated model, the coefficient of influence of bank diversification index on systemic risk in panel data regression model is equal to 1.45 and in quantile regression it is equal to 1.33. In addition, according to the results of the quantile regression, it can be stated that the effect of diversification index of sources and expenses in different banking groups has been different according to the level of systemic risk. The high level of systemic risk in Iran shows that despite the existence of supervision of some financial institutions, the systemic risk of financial activities is excessive, and this perhaps suggests the need for an effective supervisory authority.
