The USDA lowered its US corn yield and production forecasts in its November 10 report, with the national yield cut to 179.6 bushels per acre from 181.2. Export demand for 2026/27 corn was also trimmed to 83.19 million tonnes, while soybean yield was raised to 53.3 bushels per acre.
The commentary says CBOT corn futures were trading near 449 cents in December.
A smaller US corn crop and lower export demand pull in opposite directions, so the net effect on corn prices depends on the balance of supply cuts and demand reductions. Soybean yield gains add supply, but the commentary expects a bottom to form in November.
