Soy, Corn and Wheat Trackers Fall After USDA Trims Corn Yield
Chicago soybeans, corn and wheat all settled lower on Friday, September 18, 2026. We read the board through the lens of Brazil, Argentina and China demand. The post Soy, Corn and Wheat Trackers Fall After USDA Trims Corn Yield appeared first on The Rio Times .
On Friday, September 18, 2026, soy, corn, and wheat trackers experienced a market-wide decline as the US USDA reduced corn yield forecasts. Wheat led the drop, falling 1.45% to $25.86, while soybeans eased 1.04% to $27.68 and corn slipped 0.66% to $19.70. The news highlighted that US production revisions, particularly a cut to Kansas corn output expectations, were the main drivers of the market move.
Despite the lower US yield outlook, Brazil and Argentina remain the world's main suppliers of soybeans and corn to China. The session was not driven by fresh China demand, as there were no new purchases from the country to counteract the technical selling. The next key indicator to watch will be China's update on soybean import margins and any revisions to the US corn yield forecast, which could influence further import decisions from Brazil and Argentina.
