US Grain Market Hit by Harvest Shock as Corn and Soybean Prices Slide
The US grain market is experiencing a harvest shock as corn and soybean prices slide due to increased supply. The USDA data shows that a massive grain and oilseed supply is entering the market, putting pressure on commodity prices at a critical moment for producer cash flow.
Corn futures dropped 5.75 cents to $5.2750 per bushel in overnight trading, reversing part of Monday's advance. The national average cash corn price was just below $4.87 per bushel. Harvest pressure is becoming a central market force, but forecasts for substantial rainfall could temporarily slow fieldwork and limit the speed at which new-crop supplies reach elevators.
The USDA lowered its national corn yield estimate by 2.2 bushels per acre to 178.5 bpa, a figure 4.3% below last year's record, while projected production fell by 213 million bushels to 15.8 billion bushels. The crop is expected to rank as the second largest on record.
Soybeans are facing an even clearer supply challenge with November futures falling 9.25 cents to $12.95 per bushel after the market had rallied more than 10% since mid-August. USDA unexpectedly raised its national soybean yield estimate to 52.8 bushels per acre and projected production at a record 4.575 billion bushels, nearly 7% above 2025.
