Grains: Wheat, Corn and Soybeans Daily — 2026-10-31
Top developments
Wheat faces ninth weekly loss amid Black Sea competition
CBOT wheat futures edged lower on Friday, October 30, marking a ninth consecutive weekly loss. Prices were pressured by expectations of increased Russian wheat exports, which offset strong U.S. export sales data. The most-traded wheat contract was quoted at $6.06-3/4 a bushel on Friday, reflecting the market's sensitivity to global supply dynamics.

Soybeans extend losses despite strong export sales
Soybean futures extended losses on October 29, closing at $12.22-1/4 per bushel for November delivery. Despite the USDA reporting net sales of 2.576 million tonnes for the 2026/27 crop—a figure above analyst expectations—prices fell due to advancing harvest progress in the U.S. and competitive pressure from Brazilian soybeans.

Corn holding steady near four-month lows
December corn closed up 3 cents at $4.51¾ per bushel on October 28, rebounding slightly after hitting near four-month lows. The market is balancing ample new-crop supplies against steady export demand, with basis levels showing mixed trends across Midwest elevators.

Russian wheat exports surge via Baltic routes
Russian wheat exports for July–October 2026/27 are projected to reach 10.3 million tonnes, with up to 65% of shipments routed through Baltic ports. This shift is driven by logistical constraints in the Black Sea region, where recent attacks on infrastructure have hindered traditional export paths.

Local view
Brazil: Brazilian corn prices fell in most regions during the week of October 19–23, pressured by lower international benchmarks and export volumes 12.1% below the daily average of October 2025. Conab’s weekly analysis highlights the disconnect between domestic supply strength and weak global demand.

Argentina: In Argentina, the Rosario grains market saw soybean prices drop by US$10,000 per tonne over the week ending October 30, while wheat offers improved. The Bolsa de Comercio de Rosario projects record corn exports for the 2025/26 campaign at 45 million tonnes, driven by competitiveness and Black Sea disruptions.

Context & numbers
- USDA Export Sales (Oct 16–22): Wheat net sales hit a marketing-year high of 849,800 metric tons, while corn sales fell 15% and soybean sales declined 9%. Soybean exports to China jumped 18%.
- China’s Soybean Commitment: China has purchased approximately 16.6–17 million tonnes of U.S. soybeans since early July, nearing 70% of its commitment. However, near-term crush margins for importing Brazilian and U.S. soybeans remain in negative territory.

On the radar
- Black Sea Logistics: Russian grain exports via the Sea of Azov resumed on October 28 after a three-month paralysis, potentially easing some pressure on Black Sea routes but not fully resolving logistical bottlenecks.
- U.S. Harvest Progress: Traders are closely monitoring the final stages of the U.S. corn and soybean harvest, with weather patterns in the Midwest remaining a key driver for basis levels and short-term price volatility.
- Argentine Corn Exports: October corn exports from Argentina are projected to set a new record, driven by high competitiveness and supply gaps in other major exporting regions.
