Cbot Grain Futures Rise as Russian Exports Decline
Wheat futures rose at the Chicago Board of Trade (Cbot) on Oct. 1 as limited exports from Russia and Ukraine, combined with severe weather in the U.S.
Black Sea Exports Drop Amid Conflict
The ongoing war between Russia and Ukraine continues to constrain the flow of grain from the world’s largest exporter. While Russia’s estimated output is down by 5 million tonnes year-over-year, Ukraine is also seeing a decline. The USDA reports that Ukrainian wheat exports will reach 12.5 million tonnes, a decrease from the 14.1 million tonnes recorded during the previous trading campaign, Il Sole 24 Ore Radiocor reported.
Heavy Rainfall Disrupts U.S. Planting and Harvests
Heavy rainfall across the U.S. Midwest has pushed prices higher by disrupting critical agricultural timelines. Excessive rain from Colorado to Illinois is currently slowing the planting of winter wheat and delaying the harvest of corn and soybeans in several regions. Multiple states remain under flash flood and flooding alerts, further complicating field operations.

U.S. Grain Stocks Show Mixed Trends
Quarterly data released by the USDA shows a significant divergence in the availability of different grain types as of Sept. 1:
- Wheat: Stocks fell to 1.85 billion bushels, a 14% decrease compared to the previous year.
- Corn: Stocks rose to 2.1 billion bushels, marking a 35% increase over the prior year.
- Soybeans: Old crop stocks stood at 315 million bushels, down 3% annually.
Ethanol Production Hits Eight-Month Low
The Energy Information Administration (EIA) reported a downturn in fuel production for the seven-day period ending Sept. 25. Ethanol production dropped to its lowest level in eight months, and coinciding inventories also declined.
Cbot Market Outlook
| Commodity | Current Trend | Primary Driver |
|---|---|---|
| Wheat | Bullish (Rising) | Lower Russian/Ukrainian exports & U.S. rain |
| Corn | Mixed/Contrast | High stocks vs. harvest delays |
| Soybeans | Mixed/Contrast | Slightly lower stocks vs. harvest delays |
Common Questions About Current Grain Volatility
Why is Russian wheat export data affecting Chicago futures?
Russia is the world’s largest wheat exporter; therefore, any reduction in its volume—such as the projected drop from 48 million to 43 million tonnes—reduces global supply and drives up prices on the Cbot.
How does winter wheat planting differ from the current harvest?
While farmers are currently trying to harvest corn and soybeans, they must simultaneously plant winter wheat; the heavy rains mentioned by Il Sole 24 Ore Radiocor block both activities, creating a double-sided supply risk.
The current wheat stock decline of 14% follows a period of high volatility in the Black Sea region that has redefined global trade routes since 2022.
