Chicago corn futures recorded the largest decline since 2024, due to the unexpected increase in US yield expectations by the Department of Agriculture.

CBOT corn futures saw their largest decline since July 2024, after the US Department of Agriculture raised its supply expectations for US corn, while analysts had expected a decrease in supply. The agency, in its monthly supply and demand outlook report, increased both the average yield and production of corn to record highs, with quarterly stocks and end-of-quarter stocks also higher than expected. Chicago corn futures gave back earlier gains, falling by as much as 4.1%.
