Chicago wheat, corn and soybean futures all fell on October 7, 2026, with wheat posting the largest percentage decline. A Dow Jones market report linked the pressure to record Treasury yields and a stronger U.S. dollar. Separately, recent University of Illinois Extension reports described weather-delayed harvest progress and a forecast for warmer, drier conditions across the Midwest. These are dated market and weather reports—not live prices or an October 8 settlement.
What happened to Chicago grain futures on October 7?
Dow Jones reported declines in all three contracts it covered during the October 7, 2026 session:
| Contract | Reported change | Reported price |
|---|---|---|
| December Chicago wheat | Down 2.6% | $6.86 per bushel |
| December Chicago corn | Down 1.2% | $5.02 per bushel |
| November Chicago soybeans | Down 0.6% | $12.95¾ per bushel |
Wheat fell the most in percentage terms. Brian Pullam of Linn & Associates told Dow Jones: “Usually when we see this type of trade, wheat gets the brunt of the selling in grains.” The figures above describe the October 7 session as reported by Dow Jones via MarketScreener; they should not be read as current quotes.
Why were grain prices lower?
Stronger dollar
The Dow Jones report pointed to a stronger U.S. dollar as a source of broad commodity pressure. When the dollar strengthens, U.S. grain can become more expensive for buyers using other currencies, potentially making it less competitive in export markets. That is a market mechanism, not proof that currency moves alone caused the October 7 declines.

Higher Treasury yields
The same report said Treasury yields had reached new record highs and linked them, alongside dollar strength, to pressure on commodities. It did not provide a specific yield figure, so no numerical yield comparison is available here.
Harvest and supply context
Harvest conditions provide relevant agricultural context but are distinct from the report’s stated immediate explanation for the session’s price declines. University of Illinois Extension’s October 6 closing-market report said USDA crop-progress data showed national corn and soybean harvest behind five-year averages, with weather-related delays led by Iowa. The report also discussed a rally across corn, soybeans and wheat and harvest progress, underscoring that market moves and harvest conditions can evolve quickly.
Rank #2
- AGRICULTURAL GRAIN CHECKS: This portable corn moisture tester and grain moisture meter supports on-farm reference checks for farmers, grain handlers, and grain or feed processors
- 25 CROP PROFILES: Select the matching profile for corn, wheat, soybeans, paddy rice, barley, oats, sorghum, and other supported crops before each measurement
- CONSISTENT SAMPLE PREPARATION: Use a representative sample, fill the clean and dry chamber evenly, and tighten the cap securely without overtightening for more consistent readings
- AUTOMATIC TEMPERATURE COMPENSATION: Built-in ATC adjusts the displayed result for sample temperature; for better consistency, let the meter and sample reach similar temperatures before testing
- USER-ADJUSTABLE CORRECTION: When a trusted reference method shows a consistent difference, use the correction setting to adjust the displayed value; the setting remains saved after power-off
Is rain delaying the Midwest harvest?
University of Illinois Extension’s October 5 closing-market report described rain-related harvest delays. It also relayed a forecast from EverStream Analytics meteorologist Mark Russo for warmer, drier Midwest weather that was expected to help harvest through late October. That was a forecast issued on October 5, not a guarantee or confirmation of conditions in every local area.
The October 5 program also featured agricultural economist Ed Usset discussing rain delays, local soybean basis bids and marketing ahead of the upcoming USDA WASDE report. Local conditions and bids can differ from broad regional summaries, so farmers should consult current local information rather than assume one forecast or price applies everywhere.

What should a grain-market reader take from the reports?
- The October 7 report showed declines across December wheat, December corn and November soybeans, with wheat down the most by percentage.
- Dow Jones attributed broad pressure to Treasury yields and dollar strength; the report did not establish those factors as the sole causes.
- Illinois Extension’s October 6 report described harvest progress behind five-year averages nationally and weather delays led by Iowa.
- The October 5 warmer, drier outlook was a forecast for harvest conditions through late October, not a verified outcome for every farm.
Prices, weather, crop progress and expectations around USDA reports can change rapidly. Readers making financial or farm marketing decisions should verify current contract prices, local basis bids and updated crop and weather information. The October 7 figures above are a historical snapshot, not a recommendation to trade or hedge.
