Corn futures closed lower across most contracts Wednesday, pressured by a sharp decline in crude oil prices after reports that the United States and Iran are nearing a memorandum of understanding. The agreement, if finalized, could restore safe passage through the Strait of Hormuz and open a path toward de-escalation in the region.
Most-active corn contracts lost between 10½ and 12¾ cents, with the national average cash corn price falling 11½ cents to $4.26¼ per bushel, according to CmdtyView data. The selloff in crude oil — down $6.06 on the day — weighed on grain markets, as lower energy costs reduce demand for corn-based ethanol and dampen overall commodity sentiment.

Crude Oil Drop and Ethanol Market Reaction
The sharp decline in crude oil followed reports of diplomatic progress between Washington and Tehran. A potential memorandum would address maritime security in the Strait of Hormuz, a critical chokepoint for global oil shipments. While the talks remain fluid, the prospect of eased tensions triggered a broad selloff in energy markets, which spilled over into agricultural commodities.
Corn is particularly sensitive to crude oil prices because of its role as the primary feedstock for ethanol. Lower oil prices reduce the competitiveness of ethanol as a fuel additive, potentially squeezing margins for producers and lowering demand for corn.

Weekly Ethanol Data Offers Mixed Signals
The Energy Information Administration (EIA) reported that ethanol production rose by 8,000 barrels per day in the week ending May 1, reaching 1.017 million barrels per day. However, ethanol stocks increased by 139,000 barrels to 26.02 million barrels, suggesting supply is outpacing demand.
Refiner inputs fell by 15,000 barrels per day to 902,000 bpd, while blender inputs declined by 31,000 bpd to 139,000 bpd. The mixed data points to ongoing uncertainty in the ethanol market as the summer driving season approaches.
Market Implications for Corn Traders
The combination of lower crude oil prices and rising ethanol stocks creates headwinds for corn prices in the near term. Traders are now focused on Thursday’s USDA Weekly Export Sales report, which will provide fresh data on demand for both old-crop and new-crop corn.
Market expectations for old-crop corn bookings range from 1 million to 1.8 million metric tons for the week ending April 30. New-crop sales are estimated between zero and 150,000 metric tons. Strong export numbers could help stabilize prices, while weak demand may accelerate the selloff.
Contract Settlement Details
Wednesday’s settlement prices reflected the broad weakness across the corn futures curve:
- May 2026 Corn: $4.52¾, down 12¾ cents
- July 2026 Corn: $4.68½, down 11½ cents
- December 2026 Corn: $4.90, down 10½ cents
- Nearby Cash Corn: $4.26¼, down 11½ cents
- New Crop Cash Corn: $4.46¼, down 10½ cents
Conclusion
Corn markets face near-term pressure from falling crude oil prices and mixed ethanol fundamentals. Traders will closely watch Thursday’s export sales data for signs of sustained demand. The broader outlook remains tied to energy market developments and the progress of US-Iran diplomacy, which could continue to influence commodity price direction in the weeks ahead.
FAQs
Q1: Why does crude oil affect corn prices?
Corn is the primary feedstock for ethanol production. When crude oil prices fall, ethanol becomes less competitive as a fuel additive, reducing demand for corn from ethanol producers and pressuring corn futures lower.
Q2: What is the Strait of Hormuz and why does it matter for corn?
The Strait of Hormuz is a narrow waterway between the Persian Gulf and the Gulf of Oman, through which about 20% of the world’s oil passes. Any disruption or resolution affecting shipping there can significantly impact global oil prices, which in turn influence agricultural commodity markets.
Q3: When is the USDA Weekly Export Sales report released?
The USDA releases its Weekly Export Sales report every Thursday morning. It provides data on US agricultural export commitments, including corn, soybeans, and wheat, and is closely watched by traders for signs of demand strength or weakness.
