Today Markets Analysis: US corn futures finished Wednesday lower across the board, with contracts declining 1½ to 2¼ cents as traders weighed rising ethanol inventories, expectations for Thursday’s export data and a larger Canadian corn crop. December 2026 corn closed at $5.34¼ per bushel, down 1½ cents, while March and May 2027 contracts also fell 1½ cents.

The fundamental picture remains mixed. US ethanol production continues to run above year-ago levels, supporting domestic corn demand, but rising ethanol stocks and stronger Canadian production are providing counterweights. Meanwhile, Thursday’s US Export Sales report could provide the next significant catalyst for prices.

Corn Futures Finish Lower Across the Curve

December 2026 corn futures closed at $5.34¼, down 1½ cents.

March 2027 corn also fell 1½ cents to $5.48¾, while May 2027 declined 1½ cents to $5.55¼. The CmdtyView national average cash corn price slipped 1½ cents to $4.89.

The relatively uniform weakness across the futures curve suggests that traders remain cautious rather than aggressively repositioning in either direction.

Bullish Sentiment

• Strong ethanol production: US ethanol production averaged 1.099 million barrels per day, remaining 4.17% above the same week last year.
• Higher ethanol usage: Refiner inputs increased to 911,000 barrels per day, indicating continued demand from the domestic fuel sector.
• Higher ethanol exports: Exports rose by 14,000 barrels per day to 161,000 bpd, providing an additional outlet for US ethanol.
• Export demand potential: Traders are expecting 700,000 to 2 million tonnes of US corn sales for 2026/27 in the week ending September 10.
• Strong domestic processing: Ethanol production remaining above year-ago levels continues to underpin an important source of US corn demand.

Bearish Sentiment

• Rising ethanol inventories: US ethanol stocks increased by 33,000 barrels to 25.22 million barrels.
• Stocks remain above last year: Ethanol inventories are now 11.58% above the same week last year, potentially indicating that supply is running ahead of demand.
• Larger Canadian crop: Statistics Canada estimates Canadian corn production at 16.55 MMT, up 11.3% year-on-year.
• Corn supply remains substantial: Higher Canadian production adds to North American availability and could increase competition within the regional market.
• Futures closed lower: All three quoted futures contracts ended Wednesday in negative territory, showing that current demand support was insufficient to lift prices on the session.

Ethanol Production Remains a Key Source of Corn Demand

The US ethanol market continues to provide an important demand signal for corn.

Weekly production was reported at 1.099 million barrels per day, unchanged from the previous week and 4.17% higher than the same week last year.

Refiner inputs increased by 3,000 barrels per day to 911,000 bpd, while ethanol exports climbed by 14,000 bpd to 161,000 bpd.

The production figures therefore remain supportive for corn consumption.

However, ethanol inventories increased by 33,000 barrels to 25.22 million barrels, putting stocks 11.58% above year-ago levels.

This creates an important tension for the market: production and usage remain strong, but inventories are also building.

If ethanol demand continues expanding, the higher production rate could translate into sustained corn consumption. If inventories continue rising faster than demand, however, the supportive effect of the ethanol sector could weaken.

US Export Sales Become the Next Major Catalyst

The market will receive the latest US Export Sales figures on Thursday morning.

Traders are looking for total US corn sales of approximately 700,000 to 2 million tonnes for the 2026/27 marketing year during the week ending September 10.

A result toward the upper end of that range could reinforce the demand side of the corn market, particularly if export commitments demonstrate that US supplies remain competitive internationally.

Conversely, disappointing sales could increase attention on the expanding supply picture and reinforce the pressure created by rising ethanol stocks and larger Canadian production.

Canadian Corn Production Jumps 11.3%

Statistics Canada estimates Canadian corn production at 16.55 million tonnes, representing an 11.3% increase from last year.

The larger crop adds to North American supply availability at a time when traders are already assessing the size and condition of the US crop.

For the corn market, the increase is a bearish supply factor because additional Canadian production can improve regional availability and increase competition among suppliers.

The ultimate price impact will nevertheless depend on harvest conditions, domestic consumption and export demand.

Corn Market Snapshot

Strong Ethanol Demand Meets Rising Inventories

The ethanol data presents one of the clearest examples of the competing forces currently influencing corn prices.

On one side, production is running above last year’s level, refiner inputs are increasing and exports have strengthened. All three factors point toward continued demand for ethanol and, indirectly, corn.

On the other side, ethanol stocks are also higher, with inventories now more than 11% above last year’s level.

The market therefore needs to determine whether higher production reflects healthy underlying demand or is beginning to create excess inventory.

That distinction could become increasingly important for corn prices if ethanol production remains elevated while inventories continue to accumulate.

North American Supply Outlook Adds Pressure

The 11.3% increase in Canadian corn production introduces another supply-side headwind.

With Canadian output estimated at 16.55 MMT, North American availability could be larger than previously anticipated.

For US corn producers, the implications will depend heavily on domestic demand, export competitiveness and the eventual size of the US harvest.

A strong export program could absorb some of the additional supply, while weaker exports would leave the market more exposed to harvest-related pressure.

What Traders Are Watching Next

The immediate focus will be Thursday’s US Export Sales report, with traders looking for evidence that international demand can absorb available US corn supplies.

Markets will also monitor:

• US corn export commitments
• US harvest progress and yield reports
• Ethanol production and inventory levels
• Ethanol exports and refiner demand
• Canadian harvest conditions
• Global corn production estimates
• South American planting conditions
• US dollar movements and export competitiveness
• Corn futures spreads and cash-market premiums

Currency Hedger View

Corn is a globally traded commodity, meaning currency movements can influence the competitiveness of major exporters and the effective cost faced by international buyers.

Movements in the US dollar, Canadian dollar and currencies across major South American producers can alter export economics even when the underlying corn price remains unchanged.

For agricultural businesses with international revenues, purchases or sales, this creates a second layer of price exposure alongside the commodity itself.

Today Markets View

Corn is currently balancing solid underlying ethanol demand against evidence of expanding supply and rising ethanol inventories.

The fact that ethanol production remains above year-ago levels is supportive, while higher refiner inputs and exports provide additional demand signals. However, ethanol stocks are also significantly higher than last year, and the larger Canadian crop adds another supply-side consideration.

Thursday’s export data could therefore be important in determining the market’s next direction. Strong US sales would provide evidence that demand is capable of absorbing available supplies, while weaker bookings could shift attention back toward the expanding North American supply picture.

“Corn remains caught between resilient domestic demand and an increasingly important supply question. Ethanol continues to provide support, but rising inventories and larger Canadian production mean export demand will be critical in determining whether prices can regain upward momentum.” — Louis Roche, Analyst, Today Markets

Bottom Line

Corn futures finished Wednesday lower, with December 2026 corn falling 1½ cents to $5.34¼ and March and May contracts also declining 1½ cents.

The bullish case is centred on ethanol production remaining 4.17% above last year, stronger refiner inputs, increased ethanol exports and the potential for substantial US corn export bookings.

The bearish case focuses on ethanol inventories rising 11.58% year-on-year, Canadian corn production increasing 11.3% and the broader question of how much supply the global market will need to absorb.

For now, the corn market remains a contest between strong domestic ethanol demand and an expanding North American supply outlook, with Thursday’s US Export Sales report providing the next major demand signal.
