US USDA Corn Forecast Sends European Wheat Prices Down 1.1%

European wheat prices fell following a surprise U.S. Department of Agriculture forecast showing higher-than-expected American corn and soybean harvests, catching traders off guard and dragging down global grain markets. The unexpected supply outlook reversed earlier market expectations that unfavorable weather would stunt production.

December milling wheat on the Paris-based Euronext exchange closed down 1.1% at €241.50, equivalent to $270.21, per metric ton, according to an Investing.com report.

Chicago Futures and Global Spillover Effects

The downward pressure extended across the Atlantic, where Chicago wheat futures dropped 2.4% to $5.00 per bushel, reflecting the interconnected nature of global grain pricing. Because corn and wheat frequently substitute for each other in animal feed formulations, a larger-than-anticipated corn harvest directly reduces feed-wheat demand, pulling down wheat values worldwide.

Traders had largely positioned themselves for a tighter grain supply due to earlier reports of dry spells and erratic weather across key agricultural belts in the United States. Instead, the USDA crop production data confirmed large yields that forced market participants to reevaluate global inventory models.

What Limits the Downside for European Grain?

Despite the sharp drop driven by the American harvest data, European grain prices found a floor from two distinct market forces. A weak euro against the U.S. dollar improved the international competitiveness of European grain exports on the global stage, while persistent concerns over potential logistical disruptions to Black Sea shipping routes provided underlying support against steeper losses.
