Index Trading and Agricultural Commodity Prices: A Panel Granger Causality Analysis


  • Gunther Capelle-Blancard
  • Dramane Coulibaly


This paper investigates the causality between prices and index-based trading activity for twelve grain, livestock, and other soft commodity futures markets. We use panel Granger causality estimations based on SUR systems and Wald tests with market-specific bootstrap critical values. This approach allows to test for causality on each market by accounting for the possible contemporaneous dependence across markets. Our results confirm that there is no causality between index-based positions and commodity futures prices.
