At 10:00 AM (Brasilia time) this Tuesday (28), the September corn contract traded on the Chicago Board of Trade (CBOT) showed a slight increase of 1.75 points and 0.39%, trading at US$ cents 453.50/bushel. The December contract advanced 1.50 points and 0.32%, to US$ cents 475.50/bushel. Yesterday (27), the September contract fell 2.69%, to US$ cents 451.75/bushel; the December contract fell 2.77%, to US$ cents 474.00/bushel. After the significant drop recorded the previous day, cereal prices were gaining ground again this morning, supported by the worsening conditions of North American crops in the last week. A survey conducted by the United States Department of Agriculture (USDA) up to last Sunday (26) shows that 63% of the areas are classified as good/excellent, down 4 pp compared to the previous week and lower than the 73% recorded at the same time in 2025. Of the remainder, 25% were rated as fair and 12% as poor/very poor. Vegetative development continues to accelerate: 78% of the area already sown has reached the silking stage, an advance of 19 pp compared to the previous week. The index is above the 73% recorded in the same period of 2025 and also exceeds the average of the last five years (74%). In addition, 24% of the crops have entered the heading stage, compared to 13% in the previous week. The percentage is slightly below that observed in the same period last year (25%), but exceeds the multi-year average (22%). Strong international demand also supported prices. The USDA recently reported a single sale of 197,272 tons of corn to an unknown destination, with delivery scheduled for the 2026/27 marketing year. Also on the radar are the winter crop harvest in the Center-South region of Brazil and the progress of work in Argentina.
