Corn Futures (CORN.COMM)

Q3 2026
▼2▲1

Corn swings from sub-$4 to three-year high on Black Sea and weather shocks

  • Bearish start to quarter Corn futures fell below $4 in June on bearish WASDE data, weak exports, and soft ethanol demand, setting a low base before the rebound.

    Explains the initial price weakness that opened the quarter.

  • Supply shocks drive rebound July USDA cuts, Black Sea attacks, and hot US weather tightened supply, pushing prices toward $4.85 and later a three-year high near $5.37 in August.

    Captures the main bullish forces that reversed the early decline.

  • Caps and supports battle Russia's duty suspension and favorable Midwest weather capped gains, while El Niño threats to ASEAN crops, strong US export estimates, and surging crude oil boosted ethanol demand provided support.

    Shows the tug-of-war between bearish and bullish factors that kept prices choppy.

  • Peace talks pressure prices In September, peace talks raised the prospect of restored Black Sea supply, pressuring prices, though ample supply forecasts kept corn caught between bullish demand and bearish supply risks.

    Highlights the late-quarter bearish development and the overall choppy market condition.

Corn swings on Black Sea peace hopes, USDA data, and biofuel demand

  • Russia-Ukraine peace talks could restore Black Sea grain exports Putin signaled openness to peace talks, raising the chance that Black Sea grain exports resume. More corn supply would push prices down. Corn fell 0.74% on the news. This is a real counterweight to the earlier supply fears.

    Directly answers why corn moved: peace hopes could ease the supply crunch that had lifted prices.

  • El Niño threatens ASEAN grain supplies, lifting corn demand OCBC warns El Niño will drive up corn and wheat prices, hitting ASEAN importers. Higher world prices mean stronger demand for corn, supporting futures. This adds a new demand-side reason for corn to stay elevated.

    Shows a new demand driver from weather that supports corn prices.

  • USDA report: higher corn exports but ample supply USDA raised US corn export estimates, which supports prices, but also pointed to higher soybean output and a slight improvement in corn crop ratings, signaling ample supply. Corn fell after the report. The tug-of-war between strong demand and ample supply keeps prices choppy.

    Captures the key USDA data that moved corn both ways this period.

  • Crude oil surge boosts biofuel demand for corn Crude oil jumped on tanker attacks, making biofuels more competitive. Corn is used to make ethanol, so higher oil prices increase demand for corn. This helped corn gain 0.47% on Sept 15. It's a new supportive force.

    Explains a new positive driver: oil prices lifting corn via biofuel demand.

Corn hits 3-year high on USDA cuts, Black Sea attacks

  • USDA cuts yield and stocks The USDA cut its corn yield and ending stocks forecasts, and crop ratings fell. A Midwest crop tour confirmed smaller yields, pushing December corn to a three-year high near $5.37.

    This is the main fundamental driver of the price rally during the period.

  • Black Sea attacks halt exports Attacks in the Black Sea region nearly stopped grain exports from a key global supplier. This tightened world supply and helped push global food prices to three-year highs, with banks warning of a grain crisis.

    Geopolitical disruption was a major force behind the price surge.

  • Russia suspends grain export duties Russia suspended grain export duties through the end of 2026 to help exporters reroute shipments. This could add some supply, but limited Baltic port capacity means it won't fully offset lost Black Sea volumes.

    This is the main counterweight that kept prices from rising even more.

Corn hits 3-year high as US crop shrinks and Black Sea exports stall

  • US corn crop smaller than expected A Midwest crop tour found Illinois and other key states' corn yields below USDA forecasts, with hot weather hurting the crop. Less corn grown means tighter supply, pushing December corn to a three-year high near $5.37 a bushel.

    This is the main new force lifting corn prices this period.

  • Black Sea grain exports nearly halted Russia and Ukraine escalated attacks on ports and ships, stopping most grain loading from the Black Sea, which handles over 70% of Russia's exports. With Ukrainian corn and Russian wheat stuck, buyers turn to other sources, lifting corn prices.

    Geopolitical disruption to a major export route is a key new driver of corn's rise.

  • Wall Street warns of grain crisis Major banks issued grain crisis warnings, and corn and wheat hit three-year highs. A Chinese corn-seed stock, Wanxiang Doneed, hit five straight daily limit-ups. This shows broad market fear of tight grain supplies, which keeps corn prices elevated.

    It shows the wider market reaction and reinforces the supply-driven rally.

  • Russia suspends grain export duties Russia cut its grain export duty to 0% until end-2026 to help its exporters reroute after Black Sea disruptions. This could add some Russian corn to global markets, a mild counterweight, but limited Baltic port capacity means it won't fully offset lost Black Sea supply.

    It is the main counterweight to the rally, but its impact is limited by logistics.

USDA cuts corn yield and stocks, sending prices to two-week high

  • USDA cuts yield and ending stocks The August USDA report cut the corn yield estimate and lowered ending stocks to 1.653 billion bushels, tightening the supply picture. December corn jumped 20 cents to $4.81, its highest in two weeks, as traders priced in less corn available than expected.

    This is the single biggest new supply shock of the period and directly explains the price rally.

  • US crop condition ratings drop The USDA cut its good-to-excellent corn rating by 2 points to 61%, signaling the crop is not as healthy as hoped. Lower ratings raise fears of a smaller harvest, which supports higher corn prices.

    It is a fresh supply signal that adds to the tightening narrative and helps explain the rally.

  • Black Sea attacks disrupt grain exports Ukrainian drone attacks on Russia's main wheat export port forced terminals to suspend operations, and fighting in the region continues to threaten grain shipments. Any disruption to Black Sea supply makes corn relatively more valuable and lifts prices.

    It is a new geopolitical supply risk that directly supports corn prices alongside the USDA cuts.

  • Global food prices hit three-year high on drought The UN food price index rose to its highest since early 2023, driven by cereals and concerns about drought in US growing areas and a severe European grain shortfall. Tight global grain supplies keep upward pressure on corn prices.

    It shows the broader global supply backdrop that reinforces the bullish case for corn.

Corn swings on USDA cuts, Black Sea attacks, weather

  • June WASDE and weak demand The June WASDE raised US and world corn stockpiles, while weak export sales and lower ethanol output signaled softer demand. Long liquidation pushed prices below $4.

    Explains the early bearish pressure that drove prices down.

  • July USDA cut and IGC trim The July USDA report cut US and world stocks more than expected, and the IGC trimmed its global crop forecast. Strong export demand and higher corn oil prices also aided processor margins.

    Highlights the bullish supply revisions that supported prices.

  • Black Sea attacks and hot US weather In late July, Black Sea attacks and hot US weather lifted corn toward $4.85, with surging crude oil boosting ethanol demand.

    Identifies geopolitical and weather events that pushed prices higher.

  • Favorable weather and Thai imports Offsetting gains, favorable Midwest weather forecasts and Thailand's planned 1-million-tonne US corn import pressured prices back to $4.72.

    Shows the counterweight that pulled prices down from highs.

Corn swings on weather, oil, and Black Sea risk

  • Black Sea attacks and hot US weather lift corn Attacks on Ukrainian grain ports pushed wheat to a two-year high, and hot, dry weather threatened US corn areas. Both raised fears of tighter global grain supplies, helping corn futures climb toward $4.85 a bushel.

    Explains the main supply-side forces pushing corn up during the period.

  • Crude oil surge boosts biofuel demand for corn Rising crude oil prices made corn-based ethanol more competitive as a fuel additive, supporting demand for corn. This helped corn futures hold near recent highs even as wheat and soybeans pulled back.

    Shows how energy markets feed through to corn demand and prices.

  • Favorable US weather and Thai imports pressure corn Forecasts for good Midwest growing weather raised expectations of a larger US crop, sending corn down 1.8% to $4.72. Separately, Thailand's plan to import 1 million tonnes of US corn added to global supply, weighing on prices.

    Captures the main bearish supply developments that reversed earlier gains.

USDA cuts corn stocks, but weak exports and bearish start cap gains

  • June WASDE and long liquidation push corn below $4 The June USDA report raised US and world corn stockpiles, and traders dumped long positions before the acreage report. Managed money added to its bet on lower prices. Corn fell below $4 as the market absorbed a well-supplied picture.

    Explains the bearish starting point for the period and why corn was under pressure before later reports.

  • Tighter US stocks and smaller world crop lift prices The USDA's July report cut old and new US corn stocks more than expected, and world stocks were trimmed. The International Grains Council also cut its world crop forecast, while France's harvest shrank from heat. Less supply supports higher corn prices.

    This is the main bullish force in the period, showing supply tightening after the June report.

  • Weak export sales and lower ethanol output weigh on demand US old-crop corn export sales fell to a marketing-year low, and ethanol production dropped. Both point to softer demand for corn, which pulls prices down. The export slowdown was the latest drag after the July rally.

    Shows the demand side is not keeping up with the tighter supply story, a real counterweight to higher prices.

  • Strong export demand and corn oil prices support processor margins Alto Ingredients reported a big profit swing, helped by strong export demand and higher corn oil prices. Better margins for ethanol makers can mean more corn used, which is a mild positive for corn demand and prices.

    Gives a demand-side positive that partly offsets the weak export sales headline.
