Analyst: Grains follow the upward trend of crude oil.

As the conflict with Iran continues, grains on the Chicago Mercantile Exchange are following the trend of energy futures. Since corn and soybeans are used as raw materials for renewable fuels such as ethanol and biodiesel, their movements are closely tied to oil futures. Brian Grete of Commstock Investments says, "The overall market is factoring in the likelihood of the Middle East conflict prolonging, as neither side has shown any signs that the attacks will end soon. This is pushing up buying in the grain and soybean markets." Corn futures on the Chicago Mercantile Exchange rose by 1.6%, soybean futures increased by 0.5%, and wheat futures climbed by 2.2%.
