In its monthly World Agricultural Supply and Demand Estimates (WASDE) report slated for release Friday morning, USDA is expected make changes that pale in comparison to the marketplace influence of the data released on March 31. But there are still areas that could indicate shifts in global grain supply and demand, namely world ending stocks for corn, export sales and domestic feed/ethanol demand. Measurable shifts in any of those numbers, analysts say, could cause some market reaction, but in general, market-watchers say they expect just slight adjustments, with a reduction in overall U.S. corn ending stocks being the number to watch closely for its market influence. Pre-report estimates range between 1.346 to 1.502 billion bushels. See more of what to expect from Friday’s WASDE report.
