Corn prices fell 5 to 8 cents at midday Thursday, reversing Wednesday's gains, as poor weekly export sales and a broad decline in agricultural commodities weighed on the market. USDA reported old-crop corn export sales of just 314,962 metric tonnes for the week of July 9, a marketing-year low and well below trade estimates of 500,000 to 1 million tonnes. New-crop sales for 2026/27 came in at 311,222 tonnes, a six-week low, though accumulated commitments of 6.859 million tonnes remain 14.5% above last year. The International Grains Council cut its 2026/27 world corn production forecast by 4 million tonnes to 1.306 billion tonnes, while France reduced its crop estimate by 3 million tonnes due to heat damage. The CmdtyView national average cash corn price dropped 8 cents to $4.09 1/2, with September futures at $4.40 1/4 and December at $4.63.
