Grain Markets Plunge Amid Weather Worries and Chinese Trade Tensions

Grain markets experienced significant fluctuations over the week ending July 31, 2026, due to a combination of factors. Moe Agostino, Chief Commodity Strategist at Farms.com, discussed these developments in their latest Risk Management Ag Commodity Corner+ Podcast.

The main drivers behind the market movements included changing U.S. weather forecasts, declining crop conditions, geopolitical tensions, and renewed Chinese buying activity. Agostino noted that while futures retreated towards the end of the week, much of the selling was driven by month-end fund activity rather than a shift in market fundamentals.

Improved rainfall forecasts put pressure on prices after an unusually hot and dry July across key U.S. growing regions. Agostino highlighted a larger-than-expected decline in U.S. corn and soybean crop ratings, particularly across Texas, Nebraska, Kansas, North Dakota, and South Dakota.
