President Trump's latest threat to pull out of trade negotiations with China sent a wave of uncertainty through the markets. On social media, he warned of a possible "massive increase of tariffs" if China doesn't ease its restrictions on rare earth exports. That rhetoric, ahead of scheduled talks later this month, rattled investor confidence and pushed grain prices lower, especially for soybeans, which are often viewed as a barometer for trade relations with China.

November soybean futures fell 15.5 cents to $10.0675, with January down 15.25 cents to $10.2325 - a decline of nearly 1.5%. December soymeal and soyoil contracts also closed lower, down 0.75% and 1.9%, respectively. The selling was largely technical, as traders reacted to headlines with aggressive liquidation.

Corn futures, already under pressure from ample global supplies, also took a hit. December contracts dropped 5.25 cents to $4.13, while March futures slipped 5 cents to $4.29. That translates to a 1.25% decline, reflecting not only spillover weakness from soybeans but also investor hesitation amid a murky demand outlook.

Wheat futures weren't spared either. December Chicago SRW dropped 8 cents to $4.9850, while Kansas City HRW fell 6.75 cents to $4.83. Losses across wheat markets hovered around 1.5%, dragged lower by global competition and bearish commodity momentum. Even with recent purchases from buyers like Bangladesh, global supply remains robust.

Beyond geopolitics, weather remains a crucial factor for harvest progress and price direction. NOAA forecasts show limited precipitation across much of the central U.S. over the next few days. Some areas in the upper Midwest and Northern Plains may see 0.5" to 1" of rain between Saturday and Tuesday. Looking further out, the 8-14 day outlook predicts seasonally wet conditions in the Plains and upper Midwest, with warmer-than-normal temperatures likely for much of the Corn Belt.

With grain prices struggling, farmers are leaning heavily on on-farm storage strategies. In Nebraska, Josh England and his father plan to hold grain and "sell the carry," hoping future prices justify delayed marketing. "We're going to store all that we can," he said, noting that breakeven levels are elusive under current price conditions.

In Indiana, Kyle Stackhouse is seeing fast turnaround at local elevators and ethanol plants. "I don't think we've been able to get in and out this quickly since the 90s," he shared. A nearby quick-ship bid added incentive as buyers work to fill upcoming rail shipments. Despite the low board prices, some regional basis levels remain strong, offering pockets of opportunity.

On the international front, FranceAgriMer reported that 37% of France's 2025 corn crop was harvested by October 6, near the five-year average. Wheat production in France is pegged at 1.22 billion bushels - up 27% from last year. Russia, the world's top wheat exporter, has already harvested 3.34 billion bushels this season, according to Sovecon.

Meanwhile, Brazil's biodiesel sector is expanding. Consultancy StoneX forecasts demand will reach 2.77 billion gallons in 2026, fueled by the country's B15 mandate. That would mark a year-over-year increase of 6.3%, with implications for global soy oil demand.

As volatility returns to grain markets, producers are navigating a complex landscape shaped by politics, weather, and global demand. For now, the focus remains on maximizing storage, watching basis, and hoping for a clearer path forward once trade talks resume.
