December corn settled at $5.00 and 3/4 on September 30, 2026, down 21 and 1/4 cents — the steepest move on the grain side of a session that pressured every major crop contract except soybean oil.

November soybeans closed at $12.93, off 4 and 3/4 cents. Soybean complex trade split sharply: October soybean meal fell $3.00 to $357.10 per ton, while October soybean oil held flat at 67.85 cents per pound.

Wheat followed corn lower. December Chicago wheat finished at $6.75 and 3/4, down 17 cents on the day.

Livestock markets told a different story. October live cattle gained $1.45 to close at $218.67, and October feeder cattle rose $2.77 to $336.42. October lean hogs moved against the beef complex, slipping 65 cents to $78.72.

The corn decline stands out for farm-margin math. A 21-and-a-quarter-cent drop in the December contract translates to roughly $8.50 per 500-acre corn farmer's revenue expectations on a hedged bushel basis — meaningful at a time when input suppliers have kept fertilizer and seed pricing elevated. Growers holding unpriced new-crop bushels face a narrower window to lock in returns above breakeven.

The divergence within the soybean complex also matters for crushers and livestock feeders. Soymeal's $3.00 decline softens feed-cost pressure for hog and poultry producers, even as flat soybean oil prices offer crushers little margin relief on the oil side of the board.

Strength in cattle contracts, meanwhile, reflects continued firm demand for fed beef. Feeder cattle's $2.77 advance raises replacement costs for backgrounders and stocker operators, a factor worth watching against the softer lean-hog trade.

These are settlement prices, not harvested results; condition reports and cash-market basis will determine how futures moves translate into actual farmgate revenue as harvest progresses.
