Agricultural commodities in 2026 have staged a sharp recovery from their early summer lows. Corn futures closed at $5.36 per bushel on September 15, 2026, up 33% from $4.02 on June 29; soybeans closed at $13.19, up 19% from $11.09 on the same date; and wheat closed at $7.29, up 25% from $5.81 on June 30, according to DataPorium commodity price data [1]. The U.S. Department of Agriculture's September 11 World Agricultural Supply and Demand Estimates (WASDE) explains the corn move: the 2026 crop forecast was cut by 213 million bushels to 15.8 billion on a lower yield, ending stocks fell to 1.6 billion bushels and the season-average price forecast rose 30 cents to $4.80 [2]. This note covers each crop's drivers and what the rally means for food inflation as of September 15, 2026.
Where agricultural commodities in 2026 stand after the summer
The futures record shows the turn came in early July and accelerated in late August. Corn moved from $4.25 on July 2 to $4.64 on July 23, eased to $4.39 on August 7, then rallied to $5.12 on August 28 and $5.36 on September 15 [1]. Wheat went from $5.91 on July 2 to $7.67 on August 28 and traded as high as $7.76 on September 2 before settling back to $7.29 on September 15 [1]. Soybeans climbed steadily from $11.32 on July 2 to $12.76 on August 28 and $13.19 on September 15 [1].

Corn: a smaller crop and higher price forecast
The September WASDE lowered the 2026/27 U.S. corn yield by 2.2 bushels to 178.5 bushels per acre and trimmed harvested area fractionally to 88.5 million acres, producing a crop forecast of 15.8 billion bushels, down 213 million from August [2]. Total use was cut 150 million bushels to 16.2 billion, almost entirely through lower feed and residual use of 6.0 billion, while exports were left unchanged at 3.3 billion bushels on expectations of steady demand [2]. Because supply fell more than use, ending stocks were lowered 86 million bushels to 1.6 billion, and the season-average farm price was raised 30 cents to $4.80 per bushel [2].
Globally, the USDA cut world corn ending stocks by 2.6 million tons to 272.1 million, citing lower production in India, where reduced area and below-normal rainfall hurt yields, and crop failure in Kenya after a prolonged dry spell [2]. The market had anticipated much of this: corn futures were already above $5 when the report was released, and the September 15 close of $5.36 sits well above the USDA's $4.80 season-average forecast [1][2].
Soybeans and wheat: exports and world supplies
Soybeans tell a demand story. The USDA raised 2026/27 production by 16 million bushels to 4.5 billion on a yield of 52.8 bushels per acre and slightly higher harvested area, yet ending stocks fell 10 million bushels to 310 million because the export forecast rose 25 million bushels to 1.69 billion [2]. The season-average price forecast jumped 60 cents to $12.00 per bushel, and soybean meal was raised $30 to $340 per short ton [2]. World soybean ending stocks were trimmed 0.2 million tons to 124.0 million, mainly on lower U.S. stocks [2].
Wheat is the crop where the rally ran ahead of fundamentals. U.S. supply and use categories were unchanged in September, and the season-average price was raised 20 cents to $6.40, supported partly by higher corn prices [2]. World supplies were raised 3.5 million tons to 1,103.0 million on larger crops in Australia (31.0 million tons), Canada (36.0 million) and Ukraine (26.0 million), and world ending stocks were raised 3.0 million tons to 276.3 million [2]. World trade was lowered 0.9 million tons to 211.8 million as logistics constraints slowed shipments from some Black Sea exporters [2]. Ample global stocks help explain why wheat gave back part of its late-August gain, falling from $7.67 on August 28 to $7.29 on September 15 [1].
- Corn: smaller U.S. crop, lower stocks, price forecast up to $4.80; futures already above $5.
- Soybeans: bigger crop but stronger exports; price forecast up to $12.00.
- Wheat: U.S. balance unchanged, world stocks rising; price forecast $6.40, futures well above.
What the grain rally means for food prices and farm income
Grain prices reach consumers slowly and partially. The Bureau of Labor Statistics reported that the food index rose 2.7% over the 12 months to August 2026, well below the 3.4% increase in the all-items index, which was driven by a 16.3% rise in energy [3]. Farm commodities are a small share of retail food costs; processing, transport, labor and energy dominate. The summer grain rally will show up in meat and dairy prices with a lag through higher feed costs, while the energy component, especially diesel, is the larger near-term driver of food inflation.
For farmers, the rally arrives at the right time. A season-average corn price of $4.80 and soybeans at $12.00 improve margins on a crop that is mostly harvested in October and November, and futures above those levels give producers a chance to lock in prices. The counterpoint is that high prices encourage more planting in South America over the coming months and ration feed demand, which is precisely how the USDA's lower feed-use estimate came about [2]. Investors may consider that grain markets are weather-driven and cyclical, and that the 2026 rally has already priced a smaller U.S. corn crop.
A smaller U.S. corn crop and strong soybean exports lifted grain futures 19% to 33% from their June lows, even as world wheat stocks continue to grow.
Key takeaways
- Corn closed at $5.36, soybeans at $13.19 and wheat at $7.29 per bushel on September 15, 2026, up 33%, 19% and 25% from late June lows [1].
- The USDA cut the 2026 corn crop to 15.8 billion bushels on a 178.5 bushel yield and raised the season-average price to $4.80 [2].
- Soybean exports were raised to 1.69 billion bushels, ending stocks fell to 310 million and the price forecast rose to $12.00 [2].
- World wheat supplies and stocks were raised, capping the wheat rally; the U.S. price forecast is $6.40 [2].
- Food inflation was 2.7% in August 2026, well below energy at 16.3%, so grains are not the main driver of grocery prices [3].
Frequently asked questions
Why are corn prices rising in September 2026?
The USDA cut the 2026 corn yield to 178.5 bushels per acre and the crop to 15.8 billion bushels, lowering ending stocks to 1.6 billion and raising its price forecast to $4.80; futures rose to $5.36 by September 15 [1][2].
What is the USDA soybean price forecast for 2026/27?
The September 2026 WASDE forecasts a season-average soybean price of $12.00 per bushel, up 60 cents from August, with exports of 1.69 billion bushels and ending stocks of 310 million [2].
Why did wheat prices fall back in September 2026 after the August rally?
World wheat supplies were raised 3.5 million tons to 1,103.0 million and ending stocks to 276.3 million on larger crops in Australia, Canada and Ukraine, so futures eased from $7.67 on August 28 to $7.29 on September 15 [1][2].
Will higher grain prices raise food inflation in 2026?
Only modestly and with a lag. Food prices rose 2.7% in the year to August 2026 while energy rose 16.3%, and farm commodities are a small share of retail food costs [3].
