The purpose of this paper is to design and explain the systemic risk spillover model between OPEC crude oil, Tehran Stock Exchange index and exchange rate. In this study, using the Conditional Value at Risk (CoVaR) index, the overall risk in the mentioned financial markets has been calculated. In the second step, the risk spillover between financial markets was investigated using the Markov regime change method with variable coefficients over time (MS-TVP). The data used in this study was from 06/01/2000 to 29/12/2019 with monthly frequency. The obtained results have shown that there is a positive correlation between systemic risk in the stock, oil and currency markets and there is risk contagion between these markets. In the estimation, it was found that in the first regime (low volatility), each variable had a high contribution in explaining the error caused by explaining and predicting the variance in that market, but in the second regime (high volatility), this issue was completely different. Based on the estimation, it was found that the currency market and the stock market were the recipients of the spillover effects, and on the other hand, the shocks of the oil market affected other markets.
