USDA's August Crop Production report projected the average corn yield at 174.6 bu/acre, below the trade estimate of 177.6 and July's 179.5, and the soybean yield at 50 bu/acre. USDA cut 2021-22 corn ending stocks by 190 million bushels to 1.2 billion, and Chicago corn futures jumped about 5% after the release.
A bigger-than-expected yield cut and sharply lower ending stocks tighten the corn balance sheet and lift feed grain prices. Soybean meal and feed costs are likely to firm as the smaller crop expectations are priced in.
