Corn Futures Edge Lower as Harvest Lags and Export Demand Holds Steady

Corn futures dipped slightly on Tuesday, ending the session down by less than a penny across most contract months. December 2026 corn contracts fell 1/4 cent to settle at $4.82 3/4 per bushel, while average cash prices remained unchanged at $4.42 1/2. The modest weakness came as updated agricultural data revealed that 33% of the nation's corn crop had been harvested as of October 11, trailing the typical seasonal pace by 6 percentage points even with 91% of crops reaching maturity.

Despite the slower harvesting progress, crop quality showed improvement. Condition ratings rose by two percentage points to 56% in good to excellent shape. Meanwhile, export demand provided underlying support, with weekly export shipments reaching 1.302 million metric tons. Although weekly shipments declined 7.2% from the prior week, they were up more than 7.5% compared to the same week last year, led by strong purchases from Mexico, Japan, and South Korea.

Traders will keep an eye on international buying activity and harvest weather in the coming weeks. South Korean importers recently secured 261,000 metric tons of corn in overnight tenders, signaling continued foreign appetite. Additionally, updated forecasts project Chinese corn imports at 3.5 million metric tons for the 2026/27 marketing year, reflecting a slight drop from the prior year.
