Grain markets open Thursday under pressure from a stronger dollar, falling energy prices and improving US Plains moisture, while delayed Midwest harvest activity, export demand and renewed Black Sea attacks keep important supply risks in play.
Global grain markets begin Thursday, September 17, mostly lower ahead of the latest US export sales data. Corn and wheat are under early pressure, while soybeans trade only slightly weaker as strength in soybean meal, Chinese demand expectations and slower Brazilian acreage expansion provide support. Heavy rain across the northern Midwest continues to disrupt harvest progress, while renewed attacks around Ukrainian export infrastructure keep geopolitical risk embedded in wheat.
Export Sales Become the Day’s First Major Demand Test
Weekly US export sales are one of the most important catalysts for Thursday’s session. Market expectations call for 150,000–500,000 MT of wheat sales, 0.7–2 MMT of corn sales and 0.9–2.4 MMT of soybean sales for 2026/27. With the US harvest increasing physical availability, stronger-than-expected export demand would help absorb seasonal supply, while weak bookings would reinforce pressure on corn and soybeans and make it harder for wheat to overcome the stronger-dollar environment.
Heavy Midwest Rain Continues to Delay Harvest
Weather remains supportive for corn and soybeans in the northern production belt. Heavy rain continues across the northern Midwest, slowing crop maturation and delaying early harvest activity, and the pattern is expected to persist for at least another week. Conditions are much more favorable in the southern Midwest and Delta, where hot and dry weather is helping fieldwork, leaving the national harvest outlook mixed rather than uniformly delayed.
Lower Energy Prices Remove Part of the Recent Commodity Support
Energy markets are retreating after their recent sharp advance as the damaged Saudi pipeline may reopen sooner than previously expected. Spot WTI crude is down $2.75/barrel at $99.70, RBOB gasoline is down $0.07/gallon, and heating oil is $0.19 lower. The decline removes part of the macro support that had recently benefited agricultural commodities, particularly soybean oil and the broader oilseed complex.
The Stronger Dollar Adds Another Headwind After the Fed Rate Increase
The US dollar is holding firm after reaching a seven-week high following a 25-basis-point Federal Reserve rate increase, the first increase in three years. A stronger dollar makes US agricultural commodities less competitive internationally and adds pressure at a time when exporters are increasingly dependent on strong overseas demand to absorb the new crop. The currency effect is particularly relevant for wheat and corn, where international competition remains intense.
Corn Balances Harvest Pressure Against Export and Ethanol Demand
Corn remains under seasonal pressure, but demand indicators are not uniformly bearish. US ethanol production held at 1.099 million barrels per day, 4.17% above the same week last year, while ethanol exports increased to 161,000 barrels per day. A South Korean importer also purchased 134,000 MT of corn, showing continued international demand, although Canadian production is estimated at 16.55 MMT, up 11.3% year over year, adding another source of supply.
China Remains a Potential Upside Catalyst for Corn
The corn market continues to watch for potential Chinese purchases of US supply. Expectations surrounding the upcoming US-China discussions have created hope that corn could eventually join soybeans in receiving stronger Chinese demand. At the same time, France has reduced its corn export forecast from the 2026 harvest to just 2.5 MMT, down 57% year over year, which could improve opportunities for competing exporters if global demand remains firm.
Soybean Meal Takes Over as the Strongest Part of the Complex
Soybean meal is providing the clearest support to the oilseed complex. Oct ’26 meal is up $6.00 at $367, reaching a fresh 2 1/2-year high, while soybean meal’s share of product value has climbed to a seven-month high of 51.9%. Strong meal values are helping offset weakness in soybean oil and keeping soybeans comparatively resilient despite the broader lower tone in agricultural markets.
Tightening Soybean Oil Stocks Clash With Weaker Energy Prices
Soybean oil is under pressure from the decline in crude despite relatively tight domestic inventories. October oil is down to 68.34, with the September low at 67.77 identified as the next support level. India is considering a reduction in vegetable oil import taxes to limit food inflation, while Indonesia plans to maintain its biodiesel blending mandate at 50% through 2027, postponing a move to 60% until at least 2028. These policy signals create mixed demand implications, leaving soybean oil particularly sensitive to energy-market direction.
Canadian Canola Supply Remains Relatively Tight
Stats Canada estimates the 2026/27 canola crop at 22.05 MMT, down 0.8% from last year, while Canadian soybean production is expected to rise 7.8% to 7.456 MMT. The slightly smaller canola crop provides underlying support to global oilseed values, even as rising Canadian soybean production and large South American supply continue to limit the broader bullish potential.
Better US Plains Rain Prospects Pressure Wheat
Wheat is seeing the strongest early losses as improved rainfall prospects in the US Plains remove additional weather premium. Better moisture conditions reduce concern around establishment of the next winter wheat crop and are weighing most heavily on Kansas City HRW futures. At the same time, Canadian wheat production is estimated at 36.12 MMT, down 10.9% from last year, which provides some offsetting support to the global supply picture.
Black Sea Attacks Keep Wheat Supply Risk Elevated
The softer weather outlook is being countered by renewed geopolitical and logistics risk. Russian missile strikes damaged cargo vessels near Chornomorsk and Odesa and also damaged a bridge important for moving grain toward Danube ports. Combined Russian and Ukrainian wheat exports from July through September are estimated at only 8 MMT, compared with 16.4 MMT during the same period last year, leaving the Black Sea as an important source of underlying support even as prices weaken early Thursday.
Wheat Futures
Wheat starts Thursday sharply lower as improved US Plains rainfall expectations remove weather premium. Dec ’26 Chicago wheat is down $0.13 1/4 at $7.17 1/2/bu, Dec ’26 Kansas City wheat is down $0.11 1/2 at $7.88/bu, and Dec ’26 Minneapolis wheat is down $0.07 at $7.49/bu. The stronger dollar and expectations for Russian September exports above previous estimates add pressure, while renewed attacks on Ukrainian export infrastructure and sharply reduced combined Black Sea shipments continue to limit the downside.
Corn Futures
Corn begins Thursday under modest pressure, with Dec ’26 futures down $0.03 at $5.31/bu, holding within Wednesday’s range. Seasonal harvest pressure and a stronger dollar weigh on prices, but heavy northern Midwest rain, steady ethanol production and expectations for 2026/27 US export sales between 0.7 and 2 MMT provide important support. Potential future Chinese buying remains an additional upside catalyst the market is watching closely.
Soybean Futures
Soybeans start Thursday only slightly weaker, with Nov ’26 beans down $0.02 1/2 at $13.18/bu in two-sided trade. Oct ’26 soybean meal is up $6.00 at $367, reaching a fresh 2 1/2-year high, while Oct ’26 soybean oil is down 85 points at 68.34 and crush margins are up $0.03 1/2 at $2.53 1/2/bu. Chinese demand expectations, slower Brazilian acreage expansion and harvest delays provide underlying support, but record speculative length and weaker energy prices limit further appreciation in the short term.
