Today Markets Analysis

Corn futures moved lower on Thursday, with prices falling between 1 and 4¾ cents as weaker U.S. export demand, lower crude oil prices and the approaching harvest placed pressure on the market.

December 2026 corn futures closed at approximately $5.30½ per bushel, down 3¾ cents, while March 2027 corn fell 4¼ cents to $5.44½. May 2027 futures declined 4½ cents to $5.50¾.

The latest move highlights a market facing increasing seasonal supply pressure while export demand remains below last year’s pace.

U.S. corn export sales for the 2026/27 marketing year totalled approximately 1.027 million tonnes during the week ending September 10. Although the volume remains substantial, it was 16.6% below the comparable week last year.

Mexico was the largest buyer, purchasing approximately 626,000 tonnes, while Japan accounted for another 150,200 tonnes.

International demand was nevertheless evident elsewhere. Several South Korean importers purchased approximately 260,000 tonnes of corn in an overnight tender, although the origins of the supplies were not immediately identified.

Crude oil also declined by approximately $1.34 per barrel, creating an additional headwind for corn through the energy and biofuel markets.

The result is a corn market being pulled between international buying interest and potential export demand on one side, and weaker U.S. sales, lower energy prices and seasonal harvest pressure on the other.

Corn Market Snapshot

Why Corn Prices Are Falling

The primary pressure on corn comes from a combination of weaker export sales and increasing expectations of seasonal U.S. supply.

The latest USDA export-sales figures showed 1.027 million tonnes of 2026/27 corn sales.

That is still a significant volume, but the year-on-year comparison is less encouraging.

Sales were approximately 16.6% below the equivalent week last year, suggesting that international demand has not maintained the same pace seen during the previous marketing year.

That creates a concern for traders entering the U.S. harvest period.

If production is strong while export demand remains below last year’s level, the market could face increasing pressure from growing available stocks.

Mexico Remains a Major Buyer

Mexico accounted for approximately 626,000 tonnes of the latest U.S. corn sales.

That represents more than half of the week’s reported export volume.

Mexico remains an important destination for U.S. agricultural exports, making its continued participation an important source of demand for American corn producers.

Japan purchased another 150,200 tonnes, providing additional support.

However, the overall export figure remains below last year’s comparable level.

This means traders will be watching whether Mexican and Japanese demand can accelerate sufficiently to offset the broader year-on-year slowdown.

South Korea Adds Another Demand Signal

The South Korean market provided a separate bullish signal.

Several South Korean importers purchased a combined 260,000 tonnes of corn through an overnight tender.

The origins were not announced, meaning it is not yet clear how much, if any, of that demand will ultimately translate into U.S. purchases.

Nevertheless, the tender demonstrates that international buyers remain active in the global corn market.

For traders, the question is whether additional tenders from Asian buyers will develop into sustained demand or remain focused on alternative origins.

Crude Oil Adds Pressure

Crude oil prices declined by approximately $1.34 per barrel during the session.

That matters for corn because the agricultural and energy markets are closely connected through the U.S. ethanol industry.

Corn is the primary feedstock for U.S. ethanol production.

Lower crude oil prices can reduce the economic attractiveness of ethanol relative to conventional gasoline, potentially affecting expectations for corn demand from the biofuel sector.

The relationship is not one-to-one, but energy prices remain an important component of the broader corn demand equation.

The Harvest Is Becoming the Main Supply Story

The approaching U.S. harvest is another major factor.

As combines move into the fields, physical corn supplies should increasingly reach elevators, processors and exporters.

That seasonal increase in availability can create pressure on futures prices, particularly if farmers begin selling newly harvested supplies at the same time.

The market therefore needs strong demand to absorb the incoming crop.

If export sales accelerate, ethanol demand remains firm and domestic consumption stays robust, harvest pressure could be absorbed relatively quickly.

If demand disappoints, the market could face greater inventory accumulation.

Bullish Sentiment

1. Mexico Remains a Strong Buyer

Mexico purchased approximately 626,000 tonnes in the latest reporting week, accounting for the largest share of U.S. corn export sales.

2. South Korean Importers Bought 260,000 Tonnes

The overnight South Korean tender provides evidence that international buyers continue to seek significant volumes of corn.

3. Japan Provides Additional Demand

Japan purchased approximately 150,200 tonnes, adding another major importer to the U.S. demand picture.

4. International Feed Demand Remains Important

Corn remains a critical feed grain for the global livestock industry.

Continued demand from major importers could help offset some of the seasonal pressure created by the U.S. harvest.

5. Lower Prices Could Encourage Additional Buying

The recent decline could eventually attract price-sensitive importers and commercial buyers looking to secure supplies at more competitive levels.

Bearish Sentiment

1. U.S. Export Sales Are Down 16.6% Year on Year

The most significant bearish signal is the slower pace of U.S. export demand.

Weekly sales of 1.027 MMT were 16.6% below the comparable week last year.

2. Harvest Pressure Is Increasing

The arrival of the U.S. crop will increase physical availability and could encourage additional farmer selling.

3. Crude Oil Prices Are Falling

The $1.34 decline in crude oil adds pressure through the ethanol and broader energy markets.

4. Futures Remain Under Pressure

December corn fell 3¾ cents, while March and May contracts declined even further.

The weakness across several delivery months indicates that the pressure is not isolated to the nearby contract.

5. Strong Production Could Increase Stocks

If U.S. yields prove strong while export demand remains below last year’s pace, inventories could build and place further pressure on prices.

The Export Market Is Becoming Critical

Corn now faces an important demand test.

The U.S. is entering the period when the physical supply picture becomes clearer, making export demand increasingly important for determining the balance between production and stocks.

Mexico is providing strong demand, Japan remains active and South Korean buyers are seeking additional supplies.

But the overall U.S. export-sales figure remains below last year’s level.

That creates the central question for the market:

Can new international buying accelerate quickly enough to absorb the incoming U.S. crop?

Corn and the Energy Market

The relationship between corn and crude oil deserves particular attention.

U.S. ethanol production creates an important source of structural corn demand.

When crude oil prices decline, however, expectations for fuel-market margins can change.

This does not necessarily translate directly into lower corn demand, but it can influence the economics surrounding ethanol production and therefore the amount of corn ultimately consumed by the biofuel industry.

For corn traders, the combination of:

Lower crude oil + approaching harvest + slower exports

creates a particularly important near-term bearish combination.

What Traders Are Watching Next

The next major corn catalysts include:

• Weekly USDA export sales
• U.S. corn harvest progress
• U.S. yield estimates
• Mexico’s import demand
• Chinese corn demand
• South Korean tenders
• Japanese purchases
• U.S. ethanol production
• Ethanol margins
• Crude oil prices
• U.S. dollar direction
• South American crop prospects
• Global feed demand
• U.S. ending-stock estimates

The most important near-term variables will likely be harvest progress and export demand.

Currency Hedger View

Corn is another commodity where the underlying market price is only one part of the equation for international buyers and sellers.

Because corn is predominantly traded in U.S. dollars, movements in the dollar can materially change the effective cost for importers purchasing U.S. supplies.

For an overseas feed producer, livestock operator or agricultural importer, the exposure can therefore involve two separate variables:

Corn price risk + USD currency risk.

A weaker dollar can make U.S. corn more competitive internationally, potentially supporting export demand.

Conversely, a stronger dollar can increase the local-currency cost of U.S. corn even when the underlying futures price remains unchanged.

Today Markets View

Corn is entering a more challenging period as the U.S. harvest approaches while export demand remains below last year’s pace.

The latest 1.027 MMT in 2026/27 sales demonstrates that international demand remains substantial, with Mexico accounting for 626,000 tonnes and Japan purchasing another 150,200 tonnes.

The South Korean tender for 260,000 tonnes provides an additional indication that global buyers remain active.

However, the overall U.S. sales figure was still 16.6% below the comparable week last year, while crude oil declined by $1.34 and the approaching harvest threatens to increase physical availability.

The market therefore faces a straightforward fundamental test:

If export demand accelerates and international buyers continue securing large volumes, corn could find stronger support. If harvest supplies arrive faster than demand, seasonal pressure could intensify.

“Corn is entering a critical supply-demand window. International buyers remain active, but U.S. export sales are running below last year’s pace while the harvest approaches and crude oil prices weaken. The ability of export demand and ethanol consumption to absorb the incoming crop will be central to the next major move.”
