Volatile supply and demand reports: Myth or Reality? USDA released its monthly World Agricultural Supply and Demand Estimates (WASDE) report as well as the quarterly Grain Stocks report on Thursday. The reports sent grain and oilseed markets reeling. Corn ending stocks were mostly unchanged from the December report but the expectation called for a reduction of about 100 million bushels. Corn carry-over for the 2011/12 marketing year is currently projected at 846 million bushels, down 2 million from last month and 282 million compared to the 2010/11 marketing year. The mild change was a result of both an increase in production by 48 million bushels – stemming from an increase in yield from 146.7 bu/ac to 147.2 and a slight bump of 100,000 harvested acres – as well as a jump in corn exports by 50 million bushels. Thus, the combined effect was a drop in ending stocks by 2 million bushels.
