USDA's November 10 WASDE cut the national corn yield to 179.6 bushels per acre from 181.2 in October, lowering the 2026/27 crop estimate to 15.893 billion bushels. Soybean futures rallied about 43 cents and corn rose roughly 10 cents after the report, which also defied trade expectations for a large soybean yield increase.
A smaller US corn crop and tighter ending stocks raise feed grain costs for buyers and support corn and soybean prices. The lower carryout leaves less room for error if South American supplies disappoint.
