Corn futures finished Wednesday with most contracts lower through next July, while deferred months posted gains. The session reflected a mixed picture of improving supply outlooks alongside support from spillover strength in wheat and concerns that intensifying activity in the Black Sea could tighten global grain flow expectations.
In the U.S. physical market, the CmdtyView national average cash corn price rose 20 1/4 cents to $4.27 1/4, while deferred pricing strength suggested traders were balancing near-term pressure with the prospect of tighter conditions further out the curve.
Key takeaways
- Price move: Corn futures were down 18 to 20 1/2 cents through next July, while deferred contracts gained 4 to 11 1/2 cents; Sep 26 Corn closed at $4.57, up 20 1/4 cents.
- Catalyst: New supply data from the USDA’s Crop Production report showed higher yield and expanded planted and harvested acreage, offset by support from wheat spillover and reports of increasing Black Sea strikes.
- Supply picture: Production was estimated at 16.013 billion bushels, 13 million bushels above the July WASDE figure and nearly 80 million bushels above estimates referenced in the report.
- Market implication: Upside in deferred contracts points to investor focus on export and ending-stock balances beyond the current marketing year.
- What to watch: Thursday’s export sales data and upcoming weather developments in key growing regions are likely to drive short-term direction.
What drove the move
USDA’s latest Crop Production report from the National Agricultural Statistics Service provided a cornerstone for Wednesday’s price action. The report pegged corn yield at 180.7 bushels per acre. It also lifted planted acreage by 1.4 million acres from the June report to 96.7 million acres, while harvested acres rose 1.2 million to 88.6 million acres.
Additional USDA farm program information showed prevent-plant acres at 1.355 million acres for corn. Together, these inputs fed into the production estimate of 16.013 billion bushels—reported as 13 million bushels above the July WASDE number and nearly 80 million bushels above estimates cited in the article—adding to the sense of an ample domestic supply backdrop.
Beyond the purely production-focused view, the WASDE framework offered another layer. According to WASDE data, ending stocks for 2025/26 declined by 75 million bushels versus last month, supported by an increase to exports at 1.945 billion bushels. New-crop ending stocks were indicated at 1.653 billion bushels, reflecting lower carryover and higher new-crop export potential.
Outside the U.S., world ending stocks were down 0.6 million metric tons in new-crop estimates to 274.66 MMT. The report also showed Brazil 2025/26 production up 2 MMT to 140 MMT, while Argentina production remained at 63 MMT; however, the Rosario Grains Exchange raised its projection by 2.5 MMT to 70.5 MMT, with 2026/27 at 66 MMT.
Market reaction and key follow-through
While the day’s tape reflected deferred strength, the direction was not uniform across the curve. The article indicated contracts through next July closed lower by 18 to 20 1/2 cents, whereas deferreds were higher by 4 to 11 1/2 cents. That split aligns with traders treating current supply data as a near-term pressure factor while still pricing potential balance-sheet tightness later.
Support also came from cross-market influences. The report cited spillover gains from wheat and increasing Black Sea strikes as additional support, suggesting concerns around regional disruption continued to influence the broader grain complex.
Energy and ethanol demand signals offered another data point. EIA data released Wednesday showed ethanol production at 1.117 million barrels per day in the week of August 7, up 10,000 bpd from the prior week. Ethanol stocks were listed at 24.798 million barrels, up 274,000 barrels week over week—an element investors often watch for indications of the near-term strength of corn’s domestic ethanol usage.
Weather and upcoming catalysts
Weather conditions added uncertainty to the demand and supply outlook. The article said storms across parts of the I-states and Ohio on Tuesday brought flash flooding with some heavy localized rains, alongside strong winds reaching the high 90s. The NWS Storm Prediction Center noted preliminary indicators suggesting a derecho could form from eastern Iowa to northern Indiana, though the extent of potential damage was described as unknown at the time.
Near-term trading is expected to focus on export demand. Export Sales data is scheduled for Thursday, with traders looking for net cancellations ranging from 100,000 MT to net sales of 400,000 MT on old-crop corn for the week of August 6. New-crop sales were expected in a range of 0.8 to 1.4 MMT, per the expectations cited in the article.
For reference, the article reported Sep 26 Corn closing at $4.57, up 20 1/4 cents; nearby cash at $4.27 1/4, up 20 1/4 cents; Dec 26 Corn at $4.80 3/4, up 20 1/4 cents; Mar 27 Corn at $4.96 1/2, up 20 1/2 cents; and new-crop cash at $4.31 3/8, up 20 1/2 cents.
Looking ahead, investors will likely weigh Thursday’s export sales report against ongoing balance-sheet narratives from WASDE and production estimates, while continuing to monitor Midwest storm impacts and Black Sea developments that can quickly reprice risk in the grain complex.
