Corn futures remained above $5.10 per bushel, close to their highest level in more than three years, as concerns about disruptions to Black Sea grain exports supported prices ahead of the region’s peak corn export season. That export window begins in October, while continuing attacks are disrupting shipments from Ukraine and Russia. Ukraine supplies roughly 10%-11% of global corn exports, making extended interruptions a potential constraint on worldwide availability. The USDA (U.S. Department of Agriculture) reported a net reduction of 829,600 metric tons in U.S. corn sales for the 2025/26 marketing year during the week ended Aug. 27. However, accumulated exports rose to 85.06 million tons from 83.49 million tons a week earlier. Traders are also assessing U.S. crop prospects before harvest and awaiting the USDA’s updated crop estimates on Sept. 11.
