What this price means for Iowa Corn farmers
Iowa's corn price for September 2026 was $4.72/bu, $0.09 below the national average of $4.81/bu. State-level basis explains most gaps like this: transport costs, local elevator competition and crush or export demand set the discount, not farming quality. The 2025 marketing-year average (MYA) stands at $4.10/bu, lower than the prior year's $4.25/bu by $0.15. The monthly price is up from $4.26 in June and July to $4.72 in September. The current MYA may still be preliminary.
The monthly print and the MYA answer different questions. A forward contract can be priced off a monthly figure such as $4.72/bu, while the MYA of $4.10/bu is the number for annual revenue planning and budgeting. The gap between the two, $0.62/bu, shows how far a single month can sit from the season's average. Budgeting a whole farm off one month adds volatility that the MYA smooths out.
