November 2026 soybean futures traded in a 35-cent sideways range for most of September, giving back none of August's rally of more than $1 per bushel but finding no fresh fuel either. The market now waits on the USDA's Oct. 9 World Agricultural Supply and Demand Estimates report to settle the biggest open question of the season: the size of the U.S. crop still standing in fields.

Three forces held prices in place through late September, according to market analyst Naomi Blohm of Total Farm Marketing. Domestic crush demand stayed strong, the crop size remained an unknown, and export demand from China slowed to a crawl.

What does the Oct. 9 WASDE change?

Heading into October, traders had no firm read on whether summer heat cut yields or whether timely Midwest rains were enough to deliver record yields in some regions. Late-September rains kept the harvest pace modest and kept the production number a question mark.

The WASDE report will put the first authoritative yield and production estimates on the table since the uncertainty set in. Until those numbers land, harvest results remain anecdotal — condition reports and cash yields, not a final crop figure.

Why did China news push prices lower?

Chinese buying of U.S. soybeans slowed in late September, and U.S.-China trade negotiations delivered what the market read as a disappointment: Beijing left its 10% tariff on U.S. soybeans in place.

That news sent futures lower in the final days of September. Many traders had positioned for stronger private Chinese crusher demand on the assumption the tariff would be eliminated. It wasn't.

The commitment math still matters. China has said it will buy 25 million metric tons of U.S. soybeans this marketing year, and analysts estimate roughly half of that volume has already been purchased. Every fresh export sale announced during October will move the market, and the absence of new sales will be just as telling.

What is the fund risk for prices?

Managed money traders have built a massive, near-record net long position in soybean futures — a concentration that cuts both ways.

"Without additional bullish news soon, we may see funds exit some of those long positions and take profits, which could send soybean futures prices lower in the short term," Blohm cautioned.

The setup leaves the market vulnerable to technical selling on top of the stalemate in U.S.-China talks. A short-term downside correction is a live scenario for October.

What does the bigger supply picture look like?

The medium-term balance sheet offers more support than the short-term trade suggests. U.S. soybean ending stocks are snug. Global ending stocks are sufficient, but the global stocks-to-use ratio is trending smaller.

South America is the swing variable. With the El Niño weather pattern still strong, growing conditions in Brazil and Argentina may be compromised in the coming months. The world needs both countries to produce abundant crops in the upcoming season to meet global demand — a fact that keeps traders watching South American weather even as the U.S. harvest fills domestic bins.

For growers, the October checklist is short: harvest yield results versus expectations, the Oct. 9 USDA production and yield estimates, fresh Chinese export sales or their absence, and any sign that funds are unwinding longs. Each item carries direct implications for basis levels and old-crop marketing decisions.

If yields disappoint or South American weather turns adverse, the snug U.S. balance sheet could reassert itself as the dominant price driver; if yields land better than expected and China stays on the sidelines, the near-record fund long gives sellers of futures plenty of dry powder to work with.
