Corn futures in Chicago dropped nearly 6% by midday Friday after USDA's October Crop Production report lifted the yield outlook to 181.2 bushels per acre — well above the 177.7 bpa average analyst estimate tracked by Karen Braun, chief market analyst at Zaner Ag Hedge.

The agency now forecasts corn production at 16 billion bushels, which would mark the second-largest U.S. harvest on record. Braun noted the yield figure exceeded both last month's projection and trade expectations. Corn ending stockpiles landed at the high end of pre-report estimates.

"That's a kick in the pants to the corn market," University of Illinois ag economist Scott Irwin said.

What does the soybean outlook show?

Soybean output is projected at 4.56 billion bushels, up 7% from 2025. Average yield climbed to 53.1 bpa. Both figures would set all-time records if realized. Soybean futures slipped about 1% in Chicago by 12:27 p.m. local time.

How wide is the uncertainty band?

USDA assigns a 90% probability that final corn output lands between 15.5 billion and 16.6 billion bushels. Soybean production carries the same confidence interval at 4.35 billion to 4.77 billion bushels. The agency cautioned that harvests remain incomplete across major growing regions.

What changed on the demand side?

USDA raised its corn export outlook by 25 million bushels to 3.3 billion on larger supplies. The season-average corn price received by producers fell 10 cents to $4.70 per bushel.

For soybeans, exports moved up 10 million bushels to 1.695 billion. The season-average soybean price is projected at $12 per bushel, with meal at $340 per short ton and oil at 70 cents per pound.

How do input costs shape the margin picture?

Friday's price declines hit as farmers absorb record-high diesel bills and rising expenses for fertilizer and other key inputs. Safety-net payments from USDA have begun disbursing this month, providing partial relief. Congressional ag leaders say they intend to direct additional federal aid to producers before year-end.

What is the wheat picture?

October wheat supplies rose 8 million bushels to 1.534 billion on higher yields, even as harvested area declined. The total remains the smallest U.S. wheat crop since 1970. USDA cut the export forecast by 25 million bushels to 750 million, citing weak sales and shipments of Hard Red Winter and Hard Red Spring varieties.

How is global wheat trade shifting?

The world balance mirrors the U.S. picture: more supply, less trade. Russian wheat exports have fallen to a five-year low as the Black Sea conflict disrupts shipping and logistics. Lower U.S. competitiveness in HRW markets, where domestic prices run well above year-ago levels, compounds the export drag and pressures basis at country elevators.

With combines still rolling across the Corn Belt and confidence intervals spanning roughly 700 million bushels for corn, the next WASDE cycle will determine whether the record-setting tone of the October report holds through the final 2026 tally.
