Soybean exports remain exceptionally strong and Midwest rain continues to slow harvest, but a seven-week high in the US dollar, weaker energy markets and heavy speculative positioning keep the grain complex under pressure heading into the weekend.
Global grain markets begin Friday, September 18, broadly lower after two-sided overnight trade. Soybeans are taking the largest early losses despite another strong week of Chinese buying, corn remains trapped inside the range established after last Friday’s USDA report, and wheat continues to struggle with improving US Plains moisture and a disappointing export pace even as Black Sea logistics remain highly constrained.
US Export Sales Offer Support, but the Reaction Remains Muted
Fresh export sales provide one of the strongest fundamental demand signals heading into Friday. US wheat sales reached 325,935 MT for 2026/27, a three-week high, while corn sales totaled 1.027 MMT and soybean bookings reached 1.7 MMT, nearly double the same week last year. The figures show that demand remains active, particularly for soybeans, but the market response is restrained by harvest pressure, a stronger dollar and large speculative positions.
China Remains the Main Support Beneath Soybeans
China was the dominant buyer in the latest soybean sales data, taking 875,300 MT, while another 218,900 MT was booked to unknown destinations. Total Chinese purchases are estimated around 13–13.5 MMT, keeping export demand as the central supportive factor beneath the soybean market ahead of next week’s expected US-China summit. Expectations that reciprocal tariffs could be reduced continue to underpin sentiment, although the market has yet to receive a new catalyst strong enough to overcome Friday’s broader risk-off tone.
Sinograin Auction Adds a Near-Term Supply Counterweight
China’s state stockpiler Sinograin is expected to auction another 543,000 MT of imported soybeans on September 22. The release of government-held stocks adds nearby supply to the domestic Chinese market and acts as a partial counterweight to strong import demand. For US soybeans, this does not remove the underlying Chinese buying story, but it may temporarily reduce urgency for additional spot purchases.
Heavy Midwest Rain Continues to Slow Early Harvest
The weather pattern across the northern Midwest remains supportive to corn and soybeans by delaying fieldwork. Heavy rain is forecast from parts of South Dakota, Nebraska and Kansas through Iowa, Minnesota, Wisconsin, Illinois, Indiana and Ohio, with the wet pattern expected to persist into the middle of next week. Hot and dry conditions across the southern Midwest remain favorable for harvest, but continued delays farther north could slow the arrival of physical supply and help limit downside pressure.
Corn Remains Range-Bound Without a Fresh Bullish Catalyst
December corn has spent the entire week within the trading range established on last Friday’s USDA report day. Export sales of 1.027 MMT were respectable, with Mexico buying 626,000 MT, and South Korean importers purchased another 130,000 MT overnight after 260,000 MT of purchases on Thursday. Even so, the market lacks a sufficiently strong new catalyst to escape its current range, leaving traders focused on possible Chinese buying and the pace of the US harvest.
France’s Corn Crop Continues to Deteriorate
European corn fundamentals remain more supportive. French crop ratings fell to another record low, with only 23% of the crop rated good to excellent, down from 26% the previous week and far below 62% a year ago. Harvest has already reached 27%, compared with only 5% at the same point last year, highlighting how rapidly the crop has matured under poor conditions. The weak French outlook provides underlying support to European and Black Sea corn even as US futures struggle to find upward momentum.
Argentina Adds Another Source of Corn Supply
The Buenos Aires Grain Exchange kept Argentina’s 2025/26 corn production forecast unchanged at 64 MMT, compared with USDA’s 63 MMT estimate. Planting for the 2026/27 crop has reached 11%, adding another layer of future supply competition for US corn. With substantial South American production expected, US prices remain dependent on continued export demand and any potential improvement in Chinese buying.
Record Speculative Length Limits the Soybean Rally
Soybeans continue to face an increasingly important positioning risk. The market expects Friday afternoon’s CFTC data to show another record long position by money managers in soybean meal, while broader speculative exposure across the soybean complex remains elevated. This crowded positioning means strong Chinese demand can support prices, but it also raises the probability of sharp liquidation when macro conditions weaken or fresh bullish news fails to appear.
Biofuel Indicators Lose Momentum for Soybean Oil
Soybean oil continues to lag the stronger demand story in beans. August D4 RIN generation totaled only 693 million, down 13% from July, and remained below the pace required to reach EPA mandates. D4 RIN values have stabilized around $2.10, well below their summer peak above $2.50, reducing one of the supportive biofuel signals for soybean oil at a time when energy markets are also weakening.
Falling Energy Prices and a Stronger Dollar Weigh on the Complex
The macro backdrop is becoming less supportive. Spot WTI crude is down $0.40/barrel at $101.50, RBOB gasoline is down $0.07/gallon, and heating oil is $0.01 lower as China reportedly urges Iran to restrain Houthi activity that has disrupted Saudi oil shipments through the Red Sea. At the same time, the US dollar is moderately higher at a fresh seven-week high, increasing the cost of US commodities for international buyers and adding pressure to wheat, corn and oilseeds.
Wheat Export Demand Is Improving, but Still Too Slow
Weekly wheat sales of 325,935 MT marked a three-week high, with the Philippines purchasing 189,600 MT, Mexico 70,300 MT and South Korea 51,500 MT. However, cumulative US wheat exports remain 31% below last year, compared with USDA’s forecast for a 15% decline. Unless sales accelerate, the current export projection may remain vulnerable to a future downward revision, limiting the market’s ability to sustain rallies.
Black Sea Logistics Remain the Main Wheat Upside Risk
Black Sea disruptions remain an important counterweight to the bearish export and weather picture. 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. Turkey has proposed an agreement to end strikes in the Black Sea, but no response has yet been announced, leaving uncertainty over whether shipping conditions can normalize.
Russia is also attempting to diversify export routes, with plans for the Arctic port of Murmansk to begin handling grain in October 2026. The move highlights the extent to which exporters are seeking alternatives to Black Sea logistics, but it does not immediately remove the current restrictions on regional flows.
Better US Plains Moisture Continues to Pressure Wheat
Improving rain prospects across the US Plains remain a major bearish factor for wheat. The share of US winter wheat area in drought fell by 2 percentage points to 57%, while drought coverage for spring wheat and durum also declined to 56% and 39%, respectively. Better moisture reduces concern around establishment of the next winter crop and continues to strip weather premium from US wheat futures.
Pakistan’s Tender Keeps International Wheat Demand in Focus
Pakistan’s reported 750,000 MT wheat tender remains another potential demand catalyst, with participants reportedly asked to match the lowest offers in a range of $348.80–$353/MT C&F, depending on the port of entry. Confirmed business would help offset some of the weakness in US export demand, but the source does not provide confirmation that US wheat has secured any of the volume.
Wheat Futures
Wheat begins Friday lower in two-sided overnight trade. Dec ’26 Chicago wheat is down $0.02 at $7.25/bu, Dec ’26 Kansas City wheat is down $0.01 1/2 at $7.93/bu, and Dec ’26 Minneapolis wheat is down $0.03 at $7.49 1/2/bu. Improving US Plains moisture and an export pace running 31% below last year weigh on prices, while severely reduced Black Sea shipments, Turkey’s proposal to stop regional strikes and potential international tender demand provide underlying support.
Corn Futures
Corn starts Friday slightly weaker, with Dec ’26 futures down $0.01 at $5.29 1/2/bu in two-sided trade. Prices have remained within last Friday’s USDA-day range throughout the week, reflecting a balance between solid export demand and persistent harvest pressure. Weak French crop conditions and fresh South Korean buying provide support, but the market still lacks a fresh bullish catalyst and remains heavily focused on whether next week’s US-China summit can produce Chinese demand for US corn.
Soybean Futures
Soybeans lead the downside early Friday, with Nov ’26 beans down $0.11 1/2 at $13.08 1/2/bu. Oct ’26 soybean meal is down $5.70 at $363, while Oct ’26 soybean oil is down 33 points at 68.35 after touching a three-week low overnight, and crush margins have slipped $0.04 to $2.53 1/2/bu. Strong Chinese sales, slower Brazilian acreage expansion and harvest delays remain supportive, but record speculative length, weaker energy prices and the upcoming Sinograin auction are limiting further upside into the weekend.
