Chicago corn futures were modestly higher in early Thursday trading, building slightly on a bounce that had eased after Wednesday’s selloff. Contracts ended the prior session lower by 2 to 9.5 cents, led by the nearby maturities, while open interest rose by 15,562 contracts—an indication of fresh positioning that traders read as new short activity.
Fundamentals remained mixed as the U.S. ethanol sector posted further output growth, according to the latest government data, while attention also turned to the scheduled release of U.S. Export Sales later Thursday. Wetter conditions were also forecast for parts of the eastern Plains and Midwest, adding a weather-driven element to near-term risk for the crop.
Key takeaways
- Corn price action: Thursday morning corn futures were up slightly, after Wednesday closes were down 2 to 9.5 cents.
- Catalyst: Ethanol production and stocks data from the U.S. Energy Information Administration pointed to higher ethanol output, even as exports eased.
- Positioning: Open interest increased by 15,562 contracts, suggesting new short interest entered the market.
- Next market driver: Traders are positioned for Thursday’s U.S. Export Sales report, with expectations centered on old-crop corn demand.
- Implication: With supply-to-demand signals conflicting and weather in view, near-term price direction may hinge on exports and ethanol throughput.
What drove the move
Early Thursday gains were relatively small, reflecting a market that had already digested Wednesday’s weakness. Futures had pulled back from the earlier rebound, with Wednesday’s settlement declines ranging from 2 cents to 9.5 cents across contracts, led by the nearby positions.
On the fundamental side, the U.S. Energy Information Administration’s weekly Petroleum Status Report showed ethanol production rising by an additional 39,000 barrels per day in the week ending 7/24. That lifted ethanol output to the second-largest weekly total on record, at 1.133 million bpd.
Inventory and flow details were also notable: ethanol stocks were up by 245,000 barrels over the same week to 24.726 million barrels. Meanwhile, exports fell by 21,000 bpd to 137,000 bpd, while refiner inputs increased by 1,000 bpd to 939,000 bpd. For corn markets, these figures matter because they inform demand expectations through the ethanol pipeline, even when export demand for ethanol itself fluctuates.
Weather and demand watch
Weather expectations for the next seven days remain an active input for traders. Forecasts call for 1 to 2 inches of precipitation across much of eastern Nebraska and parts of the Dakotas, extending into Minnesota, Missouri, Wisconsin, Iowa, Illinois, Indiana, and Ohio. For crop-focused markets, even modest regional rainfall can change short-term perceptions of field conditions and progress.
Demand expectations also center on the next scheduled data release. U.S. Export Sales are due on Thursday, and market participants were looking for 300,000 to 600,000 metric tons of old-crop corn sales. For the 2026/27 marketing year, bookings were expected to total 0.5 million to 1 million metric tons in the week ending 7/23.
Market reaction and contract performance
Despite early gains, the session structure suggested a market still working through the prior day’s momentum shift. The rise in open interest—up 15,562 contracts—implied some new trading activity after Wednesday’s decline, with traders interpreting at least a portion of the build as new short interest entering the market.
Contract settlements from Wednesday provided the benchmark for Thursday’s start. Sep 26 corn closed at $4.49, down 9.5 cents, and was marginally higher in early trading. Nearby cash corn was assessed at $4.19 3/4, down 9.5 cents. Dec 26 corn settled at $4.71 3/4, down 8.75 cents, while Mar 27 corn ended at $4.87 1/4, down 8.5 cents. New-crop cash was quoted at $4.22 1/2, down 9.25 cents.
Bigger picture
The near-term corn outlook is being shaped by the tension between ethanol-side strength and export uncertainty. EIA data pointed to continued momentum in ethanol production and higher refiner inputs, but exports declined for the week. At the same time, weather patterns across key growing regions could quickly alter market assumptions, while Thursday’s Export Sales report remains a direct test of export demand for old-crop corn.
What to watch next: Thursday’s U.S. Export Sales figures and any updates to precipitation forecasts could drive the next leg in corn futures. Traders will also keep tracking weekly ethanol production and stock trends for changes in the demand channel feeding corn through processing facilities.
