Corn Closes Lower Despite More Export Business

Corn futures are up 3-4 cents in early Thursday trading, recovering from Wednesday's 1-2 cent losses, driven by a South Korean importer's 140,000 MT tender and an upward revision of Brazil's September corn export estimates to 7.61 MMT. This demand strength is partially tempered by EIA data indicating a drop in U.S. ethanol production and refiner inputs, resulting in an 866,000-barrel build in stocks. Market participants await weekly Export Sales data for further direction, with analysts expecting 1-1.8 MMT of 2025/26 sales.

Analysis

Corn markets are exhibiting conflicting signals, creating a tense balance between international demand and domestic fundamentals. Futures prices are showing a modest rebound of 3 to 4 cents in early Thursday trading, recovering from losses of 1 to 2 cents in the prior session. This upward momentum is supported by strong international demand signals, including a new tender from a South Korean importer for 140,000 MT of corn and a significant upward revision of Brazil's September export forecast by 0.49 MMT to 7.61 MMT. However, the domestic U.S. picture provides a bearish counterpoint. The latest EIA data showed a 31,000 barrel per day (bpd) drop in ethanol production, and despite this lower output, ethanol stocks increased by 866,000 barrels. This inventory build, coupled with a 22,000 bpd decline in refiner inputs, points to softening domestic demand for corn. The market appears to be in a holding pattern, as evidenced by a 5,812 contract decrease in preliminary open interest, with participants awaiting the weekly Export Sales report, where expectations are set between 1 and 1.8 MMT.

Key Decisions for Investors

• Investors should closely monitor the upcoming weekly Export Sales data; a result near the top end of the 1.0-1.8 MMT forecast would reinforce the bullish international demand thesis against weakening domestic signals.
• Consider the divergence between strong international demand, highlighted by Brazil's export revision and the South Korean tender, and weakening U.S. ethanol sector demand, which is causing stock builds despite lower production.
• Given the conflicting drivers and reduction in open interest, it may be prudent to maintain neutral to cautiously bullish positions, using the upcoming export data as a catalyst to confirm directional bias before increasing exposure.
