Corn Weakness Falling to Midday

Corn futures slid 7–8 cents midday Wednesday (Dec contract $4.29, nearby cash $3.90½) as traders digested a mix of supply and demand signals: EIA weekly data showed ethanol production rebounded to 1.091 million bpd with stocks up to 22.307 million barrels while ethanol and distillers exports were strong, and August Census data reported record corn exports of 6.397 MMT (25.4% above a year ago); meanwhile a South Korean tender bought 130–135k MT of corn and Brazil’s ANEC lifted its November export estimate to 6.36 MMT. The market reaction suggests that robust export flows and specific tender activity are providing support but rising Brazilian shipments, larger ethanol inventories and intraweek selling are pressuring nearby spreads; positioning updates from the CFTC (weekly data due) could further influence near-term volatility.

Analysis

Corn futures weakened 7–8 cents midday Wednesday with Dec 2025 at $4.29 (down 7 3/4c), nearby cash at $3.90 1/2 (down 7 3/4c), Mar 2026 at $4.41 1/4 (down 8 1/4c) and May 2026 at $4.48 1/2 (down 8c); the CmdtyView national average cash corn was reported down 7 3/4 cents at $3.97 1/2. EIA weekly ethanol data showed production rebounded by 16,000 bpd to 1.091 million bpd, ethanol stocks rose 88,000 barrels to 22.307 million, exports slipped 12,000 bpd to 145,000 and refiner inputs fell 7,000 bpd to 888,000 bpd, presenting mixed domestic demand signals. Census August data showed record monthly corn exports of 6.397 MMT (251.8 mbu), up 25.42% year-over-year and 2.76% month-over-month, while distillers exports rose 7.47% to 1.167 MMT and ethanol exports set an August record at 188.77 million gallons (up 23.76% y/y and 14.84% m/m), indicating strong export demand even as inventories grew. Trade-flow developments — a South Korean tender for 130–135k MT and Brazil’s ANEC raising November export estimates to 6.36 MMT — alongside intraweek selling and nearby spread pressure suggest the market is balancing robust export volumes against growing near-term supply; the upcoming CFTC Commitment of Traders release for the week of Sept. 30 could add positional-driven volatility when markets digest updated positioning data.

Key Decisions for Investors

• Reduce near-term directional exposure to corn futures and consider trimming long positions or adding short-dated hedges given the 7–8 cent pullback and pressure on nearby spreads
• Monitor weekly EIA ethanol production and stocks and monthly Census export figures closely, as rising ethanol inventories or larger Brazilian export estimates are triggers to increase hedges or delay new physical purchases
• For processors and basis-sensitive holders, consider locking basis or using futures-to-arrive contracts to protect margins because export tenders (130–135k MT) support demand but CFTC positioning updates may drive short-term volatility
