Political relationships can have both a positive and a negative impact on bank performance, which requires an empirical analysis to identify its impact. In this regard, the purpose of this study is to investigate the relationship between political communication and financial performance of banks accepted in Tehran Stock Exchange and OTC. In this study, in order to test the research hypothesis, financial information of 14 banks accepted in Tehran Stock Exchange and OTC was used during the period between 2013 and 2017. The research hypothesis test was performed using mixed data technique and multivariate regression. The results of the research hypothesis show that there is a significant negative relationship between political communication and financial performance of banks. In other words, political communication tends to focus less on maximizing shareholder values and will result in undermining the bank's financial performance.
