The upward movement in oil and food prices in the 2000s has triggered interest in the information transmission mechanism between the two markets. This research investigates the volatility spillover between oil, food, and agricultural raw material price indexes for the period January 1980 to April 2008. The results of the Cheung-Ng procedure show that variation in oil prices does not Granger cause the variance in food and agricultural raw material prices. However, there is bi-directional spillover between agricultural raw material and oil markets. Besides, it examines volatility spillover between maize, wheat, soybean, rice, and oil spot prices for the period January-1998 to February-2009. The results show that volatility spillover in oil returns leads fluctuations in maize, soybean, wheat, and rice returns in 3 months. In addition, there are bi-directional spillovers between oil and soybean returns, rice and wheat returns. This topic is essential for countries whose populations grow rapidly because forecasting of commodity prices plays an important role in instituting the economic policy. Also, understanding the dynamics of the economy leads to better economic policies. Thus, results are important for investors and policy makers interested in price shocks and transmission.
