USDA raises US corn yield to 181.2 bushels, record soybeans; corn prices slide

The US Department of Agriculture (USDA) raised its estimates for the American corn and soybean harvests in its monthly World Agricultural Supply and Demand Estimates (WASDE) and Crop Production reports, released on Friday, October 9, 2026. USDA lifted the expected 2026/27 corn yield by 2.7 bushels an acre to 181.2 bushels, well above what market analysts had forecast, and put corn production at 16.03 billion bushels. It also set a record soybean yield of 53.1 bushels an acre, up 0.3 bushels from September. Corn futures fell sharply on the news, dropping by between 20 and 30 cents a bushel during the session to their lowest level in several weeks.

The United States is the world's largest corn producer and one of the biggest soybean exporters, so USDA's monthly estimates move grain prices around the world. This report mattered more than usual. Harvesting across the Midwest had been delayed by historic rainfall through September, and many traders expected the wet weather to trim yields. Instead, USDA said the crops were bigger than it thought a month ago.

A larger harvest means more supply and, all else equal, lower prices. That is good news for buyers of grain, such as livestock and poultry producers, food processors and ethanol plants, which use corn as feed or raw material. It is bad news for farmers, who now face weaker prices for what they grow. Larger ending stocks, the grain expected to be left over at the end of the season, add to the downward pressure because they signal that supplies will stay comfortable into next year.

The higher soybean export estimate is a counterweight. Strong buying linked to China supports demand for US soybeans, which helps explain why soybean prices held up better than corn on the day.

For Indian readers, US corn and soybean benchmarks feed into global prices for maize, soybean meal and edible oils. Indian traders, feed makers and soybean growers watch these numbers because they shape the export and import prices that local markets compete with.

Short-term: Corn prices have dropped to multi-week lows, and grain markets will now watch harvest progress and final yields as the delayed harvest catches up.

Long-term: If the bigger crop is confirmed, ample supplies could keep global corn prices subdued into 2027, easing costs for feed and food users while squeezing farm incomes.

Who is affected: US grain farmers, livestock and poultry producers, food and ethanol companies, grain traders, and importers and exporters of maize and soybean products worldwide, including in India.
