An analyst expects USDA to trim its U.S. corn yield estimate by about 1 to 1.3 bushels per acre in Tuesday’s report and raise soybean yields by roughly 0.3 bushel per acre. He expects demand estimates to be mostly unchanged, citing strong corn exports, and notes concerns about USDA’s use of AI to check estimates after errors in earlier data.
A lower corn yield estimate would tighten expected supplies and support corn prices, while a higher soybean yield estimate could add to supplies and weigh on soybeans. These are analyst expectations ahead of the report, not confirmed USDA revisions.
