        Many people and companies make their own financial decisions on the bases of the changing and evolving political developments. In this paper we try to examine two major events, presidential election in the USA and American exit from JCPOA with their effects on the Iranian economy. For this we shalll use two methods, Multiple GARCH (DCC Model) and Analysis Variance methods. By using DCC model in this work, we show that the volatility spillover of the exchange price (US Dollar in the Free Market) has a direct impact on the overall Tehran Stock Exchange index. And by using of Varyance Analytical method we have shown the severity of this volatility spillover which was measured before and after the US election. As a result of this study one may say that due to Iran's dependency on oil export, any major political development in Iran has great impact on the Iran's economy index. Therefore, in making financial and investment decisions in Iran, all the companies consider the political conditions of the country and also the prediction of any changes in the effects of political developments.
