Banks are the engine of providing financial resources in the economy and have special importance for governments. Accordingly, presenting the factors and components affecting financing restrictions and changes in the corporate debt bonds yield, risk management, as well as changes in their stock prices, in terms of bank management and from a macroeconomic perspective, can be considered as the leader of the economy and government. On the other hand, the proper management of banking challenges and the improvement of factors affecting the efficiency and effectiveness of banking resources can move the economic cycle in the right direction, considering that the banks' primary activity is to grant loans and provide them to applicants. Accordingly, the researcher addressed the effect of the ability to manage political relations and financial crises on performance improvement. Therefore, a combination of Data Envelopment Analysis (DEA) and Two-Stage least squares (2SLS) regression analysis was used. This study is descriptive research with the correlational and post-event approach. In this way, the information about 11 banks in a period of 9 years (2014-2023) was analyzed. The results showed that the improvement of ability level and proficiency in bank management will lead to the improvement of financing constraints, changes in corporate bond yield, and the growth rate of stock and non-shared incomes. The management authority not only affects credit risks, credit risk management and liquidity risk but also does not affect the stock price drop.
