1 Impact of Futures Trading on Commodity Prices Golaka C. Nath and T. Lingareddy Vice President and Deputy Manager Research and Surveillance CCIL, Mumbai

2 Objective To study the impact of futures trading on agricultural commodity prices.

3 Methodology Simple percentage variations, correlations, Granger Causality Test Linear Regression

12 Conclusions There was a significant increase in spot urad prices during the period of futures trading Although gram prices too have posted a moderate rise in the post-futures trading period, the impact was not found statistically significant. The average price increase and volatilities in urad, gram and total pulses have gone up during the period of futures trading
