US Corn Stockpiles Surge, Futures Plummet on Shift in Market Sentiment

Corn futures in Chicago have fallen for a fourth consecutive session following a report from the US Department of Agriculture (USDA) that US corn stockpiles jumped to 35% higher as of September 1st compared to last year. The increase is attributed to a large harvest in 2025.

The larger inventory has shifted the market's focus from securing immediate supply to waiting for further production and grain movement. As a result, elevators and end-users in the US Midwest have become less aggressive in bidding for corn, leading to softer cash-market signals.

This shift is reflected in the futures curve, with nearby contracts weakening relative to later months. Holding grain now appears less urgent, and storage and financing costs are taking precedence over pricing. Other grains, such as those used in animal feed, have also experienced price drops but not to the same extent as corn.
