Key Facts
- Corn tracker rallied again — the Teucrium Corn Fund settled at US$19.59, up 1.93%, extending the rally sparked by a private tour’s cut to the US yield estimate.
- Soybeans rebounded — the Teucrium Soybean Fund settled at US$26.28, up 1.31%, recovering Monday’s dip as Chinese demand stayed strong.
- Wheat firmed on Black Sea disruption — the Teucrium Wheat Fund settled at US$25.63, up 0.59%, with Russia’s main grain terminals still shut.
- Yield estimate cut sharply — the Pro Farmer tour pegs the US corn crop at 173.2 bushels per acre, far below the USDA’s 180.7 bushels.
- China is buying — the USDA confirmed sales of 712,000 tonnes of US soybeans to China, plus another 720,000 tonnes to undisclosed destinations.
- Brazil and Argentina gain leverage — a smaller US crop makes South American soybeans and corn more valuable to importers.
Today’s Focus
Corn kept climbing on Tuesday, August 25, 2026, with the corn-tracking fund rising 1.93% to US$19.59. The rally has run since Friday, when the Pro Farmer crop tour cut its US corn yield estimate to 173.2 bushels per acre — far below the USDA’s 180.7 bushels.
Soybeans bounced back, up 1.31% to US$26.28, recovering Monday’s dip. Demand is doing its part — the USDA confirmed on Friday that exporters had sold 712,000 tonnes of US beans to China and another 720,000 tonnes to undisclosed buyers for next-season delivery.
Wheat added 0.59% to US$25.63. Russia’s grain terminals at Novorossiysk have been shut since Ukraine’s August 12 drone strike, and consultancy SovEcon expects Russian wheat exports this month to reach only 3.0–3.4 million tonnes, well below the five-year August average of 5 million.
What matters today. Corn is repricing a smaller US crop, soybeans are finding their footing on Chinese demand — and both shifts play into South American hands.
01 The session in one read
Corn rose again on Tuesday, August 25, 2026, stretching the rally that began after a private crop tour cut its forecast for the US harvest far below the government’s estimate. The corn-tracking fund climbed 1.93% to settle at US$19.59.
Soybeans regained their footing after Monday’s slip, with the soybean tracker up 1.31% at US$26.28. Wheat firmed modestly, up 0.59% to US$25.63, as the Black Sea export disruption dragged on.
The corn market is moving on a genuine supply scare: the Pro Farmer tour’s 173.2 bushels per acre implies roughly 670 million fewer bushels than the USDA’s August figure, enough to change the conversation from comfortable supplies to possible rationing. Many analysts doubt the final yield will come in that low, but the USDA could still trim its own estimate in its September 11 crop report. For soybeans, strong Chinese buying is absorbing a bearish private forecast for a record US crop. The variable to watch is whether the USDA formally lowers its corn yield next month.
02 The board
The Teucrium Corn Fund settled at US$19.59, up 1.93% on the session — the strongest move of the three grain trackers. December corn futures had closed on Monday at US$5.1550 a bushel, their highest since July 2023.
The Teucrium Soybean Fund closed at US$26.28, up 1.31%, while the Teucrium Wheat Fund ended at US$25.63, up 0.59%. Wheat’s move was more muted, reflecting a market weighing Black Sea risk against ample global supplies.

03 What moved it
Corn has been climbing since Friday, when the Pro Farmer crop tour — more than 100 scouts sampling over 3,000 fields in seven states — cut its US yield estimate to 173.2 bushels per acre, well below the USDA’s 180.7 bushels. That implies a crop of 15.344 billion bushels, about 670 million less than the government projected on August 12.
Soybeans drew support from demand. The USDA confirmed on Friday that exporters sold 712,000 tonnes of US soybeans to China and another 720,000 tonnes to undisclosed destinations, all for 2026/27 delivery — enough to offset Pro Farmer’s forecast of a record 4.572-billion-bushel US soybean crop.
Wheat firmed as the Black Sea disruption stretched into a second week. All three grain terminals at Russia’s Novorossiysk port, with combined annual capacity of about 26 million tonnes, have been shut since Ukraine’s August 12 drone strike, and SovEcon expects Russian wheat exports in August to fall to 3.0–3.4 million tonnes, against a five-year average of 5 million.
04 The Latin American read
Brazil and Argentina remain the export engine for soybeans and corn, and any US supply scare strengthens their pricing power. A smaller American corn crop makes South American cargoes more valuable to importers.
The Brazilian real is a crucial swing factor. A weaker real makes Brazilian beans and corn cheaper for foreign buyers, which can cushion local farmer margins even when dollar prices wobble.
05 The names to watch
The Teucrium Corn Fund is the clearest proxy for the corn rally, while the Teucrium Soybean Fund shows how demand and supply are fighting to a draw this week.
Brazilian exporters such as large grain traders and port operators are the key Latin American beneficiaries of a smaller US crop. Argentine farmers also gain if corn prices stay firm into their planting season.
06 The outlook
The USDA’s September 11 crop report is the main event for corn, as traders look for confirmation of the lower yield estimate. Soybean direction depends on whether Chinese buying keeps pace into the US harvest window. Wheat will track Black Sea headlines and how quickly Russia’s Novorossiysk terminals can reopen.
07 What to watch
- USDA crop report: Watch whether the USDA formally cuts its corn yield estimate on September 11, which would validate the private tour’s lower figure and likely extend the rally.
- China soybean bookings: Fresh Chinese purchases of US soybeans are supportive, but the market needs sustained volume to absorb a record US crop forecast.
- Black Sea shipping: Any delay in reopening Novorossiysk’s grain terminals would tighten wheat supply further and lift prices.
- Brazilian real: The real’s level against the dollar directly affects Brazilian farmer returns and export competitiveness for soybeans and corn.
