Corn futures ended August slightly higher, with nearby contracts gaining between 1 cent and 3 1/2 cents on the session as traders digested the latest U.S. crop and export data. The market also tracked progress in key growth stages, while shipment figures pointed to stronger year-over-year export momentum.
On the cash front, the CmdtyView national average “Cash Corn” price rose 3 1/2 cents to $4.93 1/2, reinforcing a firmer tone across both futures and physical values.
Key takeaways
- Corn futures closed higher, with September up 3 cents and other contracts also posting gains.
- Catalyst: Weekly Crop Progress data showed 62% of the U.S. corn crop in the dough stage, alongside export inspections indicating stronger shipping versus last year.
- Implication: The combination of steady crop advancement and improved export pace supported corn pricing into the start of the new marketing-year window.
- Physical market: The national cash average increased 3 1/2 cents to $4.93 1/2.
What drove the move
Crop conditions and maturity milestones provided the primary domestic read-through for traders. According to this week’s U.S. Crop Progress report, 62% of the corn crop was in the dough stage by August 30. The report also showed 62% “dented,” while 13% was listed as mature. Condition ratings were described as steady: 47% of the crop was rated in good to excellent condition.
Relative to that condition split, the Brugler500 index slipped by one point to 347, reflecting a one-point shift from “excellent” to “good.” While the headline acreage stage numbers suggest the crop continued to move through maturity on schedule, the slight easing in the index helped frame expectations for how the market could price yield risk into the final harvest window.
Export data added momentum
Export activity further supported the market tone. Monday morning’s Export Inspections report showed corn shipments of 1.496 million metric tons (58.9 million bushels) for the week of August 27. That was up 13.11% from the prior week and 6.12% higher than the same week last year.
Geographically, Mexico was the largest destination with 510,453 MT. Shipments also included 264,474 MT to South Korea and 173,086 MT to Japan.
For the marketing year totals, corn exports were reported at 83.81 million metric tons (3.299 billion bushels). This total was 25.14% ahead of the same period last year, with the marketing year set to end today—an important timing point for traders monitoring whether demand is strengthening as the season’s trade window closes.
Contract settlements across the curve
At the close, the front end and extending maturities all finished higher, indicating broader firmness rather than a localized move. September 2026 corn closed at $5.15, up 3 cents. Nearby cash was at $4.93 1/2, up 3 1/4 cents. December 2026 corn settled at $5.37 3/4, up 1 1/4 cents. March 2027 corn closed at $5.52 1/4, up 1 cent. New crop cash was $4.96 3/8, up 2 1/4 cents.
Bigger picture: Brazil crop progress in focus
Attention also remained on competing supply conditions abroad. AgRural estimated that Brazil’s 2025/26 second corn crop was 96% harvested in the center-south region, which it noted lags last year. For the 2026/27 first corn crop in the same region, AgRural reported 11% planted. These updates matter for global balance, especially as the market prices the timing of additional South American bushels into the international feed and export demand complex.
With U.S. corn advancing through dough and dent stages at a steady conditions rate, traders appeared to be weighing domestic crop development against export momentum and Brazil’s harvesting pace. The modest but broad futures gains suggest the market saw support from demand data without sharply repricing yield expectations on the day.
Heading into the next session, investors will likely watch additional weekly crop progress updates and any follow-on export inspection releases for confirmation of the stronger shipment pace. On the agricultural calendar, further attention will also turn to crop development benchmarks and ongoing Brazil planting and harvesting reports as the market works toward harvest-year clarity.
