  The main purpose of present study is to analyze the relationship between stock and exchange markets in two Asian countries, Iran and South Korea. A monthly time series of stock price and exchange rate are used over the period 2002: 05 - 2012: 03. The data is collected from the Central Bank of each country and WDI. The calculated stock return and real exchange rate change are used in analysis. An econometric multiple generalized autoregressive conditional heteroscedasticity (MGARCH) BEKK method and the Rats software are applied to analyze a dynamic relationship between two markets in each country. The estimated results show a bidirectional relationship between two markets in South Korean economy and only a unidirectional relationship from exchange market to stock market in Iranian economy. The persistence of volatility transmission effects of each market on its own is also found in each economy. In the exchange market, this effect is in opposite direction in Iran compared to Korea, whereas in the stock market both effects are positive and almost the same in two economies. The policy implication of finding is clear. The financial policymakers should watch both stock and exchange markets in two economies to prevent the bidirectional volatility effects between two markets in Korea and the unidirectional volatility from the exchange market to sock market in Iran.       JEL Classification : F31, G10
