A University of Illinois economist says recent corn price volatility signals concern over the 2017 U.S. crop. Good-to-excellent ratings fell 3 percent in the July 10 report, and forecasts call for above-normal temperatures and below-normal rain across much of the Corn Belt through July 30.
Heat and dryness during pollination could cut corn yields, tightening supplies and supporting corn prices. Feed buyers should expect firmer corn costs and related feed-ingredient prices if ratings keep slipping.
After 1,465 past bullish weather events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.9% over 20.
