Why CBOT Soybeans Have Been Rallying

CBOT soybean futures—the contracts traded on the Chicago Board of Trade—have been moving higher because traders are pricing in three developments at once: renewed Chinese purchases, weather-related risks to the U.S. crop and potentially stronger demand from the biofuel sector. The combination has encouraged investors to cover short positions and helped attract fresh buying. 101114

1. Chinese demand is coming back into focus

The market has received a series of reports of China buying U.S. soybeans for the new crop. In early August, the U.S. Department of Agriculture confirmed Chinese purchases of nearly 500,000 metric tons, improving the outlook for U.S. export demand. 11

USDA’s Foreign Agricultural Service office in Beijing also forecasts that China’s soybean imports will reach 108 million metric tons in the 2026/27 marketing year, up about 2% from the previous year. The increase is primarily linked to growing demand for soybean meal from China’s feed industry. 1

For soybean traders, actual export sales matter more than general expectations. Continued announcements of Chinese purchases can therefore provide immediate support to futures prices.

2. U.S. weather is adding a risk premium

Soybeans remain vulnerable to weather during important stages of crop development, including pod setting and seed filling. Concerns about heat and heavy rainfall across parts of the U.S. Midwest have raised the possibility that crop conditions or yields could deteriorate. 1015

That is why weather forecasts can move both nearby contracts and new-crop futures quickly. Even when a production loss has not been confirmed, traders may bid up prices to account for the possibility of lower yields.

3. Biofuel expectations are supporting soybean oil—and crushing demand

The latest U.S. biofuel policy developments have been interpreted as supportive for renewable-fuel demand. Because soybean oil is an important biodiesel feedstock, stronger soybean-oil prices can improve the economics of crushing soybeans. 14

When crushing margins improve, processors have more incentive to secure raw soybeans. This creates an additional source of demand beyond exports and helps reinforce the futures rally.

4. Record global supply may cap the rally

The broader supply picture is not yet especially tight. USDA’s August World Agricultural Supply and Demand Estimates forecast record global soybean production of 442.3 million metric tons for 2026/27, while global ending stocks are projected at 124.2 million tons. 34

That means the recent rise is better understood as a combination of improving demand and risk premiums tied to weather and policy—not as confirmation of a global supply shortage. A large U.S. or South American harvest could ultimately limit how far prices can climb. 916

What to watch next

Three indicators will be particularly important:

• U.S. crop-condition reports, field surveys and yield estimates;
• daily U.S. export-sales announcements, especially those involving China; and
• the final implementation details of U.S. biofuel policy.

If U.S. weather improves and Chinese buying slows, the risk premium could fade. But if yield estimates are cut while export sales continue, the rally would have stronger fundamental support.
