Corn futures lost some of their early Wednesday momentum by midday, with most contracts edging lower after an initial uptick in the session. The pullback came as traders digested the latest U.S. ethanol supply and demand data, while attention shifted toward Thursday’s weekly Export Sales report for fresh signals on demand.
Key takeaways
- Price move: Front-month cash corn was down a penny to $3.76 1/4 per bushel, while December and other forward months also slipped fractionally.
- Catalyst: Weekly U.S. ethanol data showed lower production and a build in ethanol stocks, pointing to weaker corn use assumptions.
- Demand watch: Traders are braced for Thursday’s weekly Export Sales, with forecasts spanning a wide range for 2024/25 sales.
- Export context: Brazil’s September corn export expectations were slightly higher versus the prior week, though still aligned with last year’s volume range.
- Implication: Near-term pricing is being driven more by biofuel balance-sheet signals and upcoming export headlines than by any single technical factor.
Ethanol data cools the corn-use outlook
U.S. ethanol figures from the week ended September 13 showed production at 1.049 million barrels per day, down 31,000 bpd from the prior week. The data suggests a decline in corn used for ethanol production, which can weigh on corn futures if it points to reduced demand for the grain.
At the same time, ethanol inventories increased. Ethanol stocks rose by 71,000 barrels to 23.785 million barrels, signaling that supply added to storage rather than tightening immediately. Weekly refiner inputs also moved higher, rising 16,000 bpd to 908,000 bpd, while ethanol exports declined by 26,000 bpd to 151,000 bpd. The combination of falling production and higher inventories implies that the domestic balance sheet is not currently pointing toward rapid tightening.
What traders look for next: Export Sales on Thursday
Market focus is now on Thursday’s weekly Export Sales release, which is expected to shape the demand narrative for the 2024/25 and 2025/26 marketing years. Traders’ estimates span 550,000 metric tons to 1.4 million metric tons for 2024/25 corn sales, while expectations for 2025/26 are concentrated at a smaller range, with forecasts of 0 to 50,000 metric tons.
The wide range of expectations highlights uncertainty around overseas buying pace. For corn futures, export confirmations can quickly shift sentiment—either reinforcing demand support or adding pressure if sales come in below market hopes.
Brazil export expectations add limited incremental support
On the international front, Brazil’s corn exports for September are projected at 6.63 million metric tons, according to market expectations referenced by traders. That would be a slight increase from the 6.47 million metric tons projection reported the previous week by ANEC. For comparison, Brazil exported 6.42 million metric tons in September last year.
While the slight upward revision suggests a marginally stronger export pace than the prior estimate, the closeness to the prior-year figure keeps the outlook relatively steady rather than dramatically changing competitive pressure for U.S. corn.
Where contracts stood by midday
By midday Wednesday, declines were modest across the curve. Dec 24 corn was around $4.11 1/2 per bushel, down 1 cent. Nearby cash corn traded near $3.76 1/4, down 1 cent. Mar 25 corn was about $4.29 3/4, down 1 cent, while May 25 corn was around $4.40 1/2, down 3/4 cent.
The relatively small moves suggest investors are not fully re-pricing the market on ethanol alone, but are instead positioning for the next confirmed demand datapoint—Export Sales—while keeping an eye on how biofuel balance sheets translate into corn consumption.
What to watch next: Thursday’s weekly Export Sales report is the next major driver for corn prices, with traders looking for clarity on 2024/25 overseas demand. Additional ethanol-related updates and follow-through on broader grain sentiment will also remain key, especially if inventories continue to build or if exports fail to rebound.
