After the unprecedented volatility of gold coin prices over the past years in Iran, there has been a growing concern among academic and policy makers about the potential role of gold coin futures contract in this regard. This paper investigates the impact of gold futures contract on the respective spot market in Iran. For this purpose, two approaches have been used. In the first approach (volatility spillovers approach), a DCC-GARCH-VECM model has been employed for studying the volatility spillovers between gold coin spot and futures markets over the period November 2013- June 2015. In the second approach (dummy variable approach), the impact of the introduction of gold coin futures contract on the spot market has been analyzed using a simple GARCH model. The model is estimated by using daily spot and futures prices of gold coin in the period June 2006- June 2015. The results show that the introduction of futures contact has not affected the volatility of the spot market. Moreover, the volatility transmission is from the spot market to the futures market meaning that spot market shocks increase futures market volatility, not vice versa. Furthermore, the results show that economic sanctions against Iran have had a significant effect on the volatility of the spot market. The results are consistent with basic characteristics of the futures market in Iran: it is in the early stages of its development and its size, in comparison to the spot market, is small. Therefore it is acceptable to see that the volatility is transmitted from the spot market to the futures market.

Undoubtedly, new developments in information and trading technologies have increased the integration of international financial markets in the world. This in turn has generated interest in examining the volatility transmission of financial market across markets.
In this paper, we investigate the co-movements and volatility transmission among the three important oil, gold and US dollar/euro exchange rate markets. Using weekly data from 1995 to 2012, we estimate a VAR-ABEKK-Mean model and find the evidence of return and volatility spillovers among the three markets. More specifically, we find strong evidence of significant transmission volatility from the oil market to the two other markets. We also show that the transmission of information is asymmetric among the three markets. In this regard, the bad news of an increase in oil prices appears to be more influential than news of a decline in its value for investors in gold and exchange rate markets.
