THE corn The price of corn rose sharply in August, both in Brazil and in the international market, driven by reduced supply expectations in the United States, worsening conditions in US crops, and sales being held back by Brazilian producers. In Sorriso, Mato Grosso, the cereal accumulated a monthly increase of 12%.
According to Itaú BBA's Agro Consulting, the average price in Sorriso reached R$ 47 per sack in August. On the Chicago Stock Exchange, the first corn futures contract averaged US$ 4.68 per bushel, an increase of 5.7% compared to July.
The shift in perception in the international market gained momentum after the USDA indicated higher demand for US exports and a reduction in ending inventories. Although US production remains high, increased consumption has reduced expectations of a surplus.
The weather also brought concern. At the end of August, only 57% of North American crops were classified as being in good or excellent condition. A year earlier, that percentage was 69%. Heat and low humidity affected areas of the Plains and the western part of the producing belt.
Another factor came from the Black Sea. Attacks on Russian port infrastructure increased logistical risks and added a premium to international prices, since the region maintains a significant share in the world's grain supply.
In Brazil, price increases occurred even as the second crop harvest progressed. Some producers chose to restrict sales in the spot market, betting on further price hikes, while domestic buyers made occasional purchases to replenish stocks.
Brazilian exports, however, lost momentum. August shipments totaled 4.7 million tons, a decrease of 321% compared to the same month in 2025. Competition from the United States and Argentina reduced the competitiveness of Brazilian corn.
For the 2026/27 crop season, attention is beginning to turn to South America. Argentina could harvest 67.5 million tons and, depending on weather conditions, reach around 70.5 million tons. In Brazil, Emater projects a growth of 7.4% in the summer corn area in Rio Grande do Sul, while Deral forecasts an expansion of 2% in Paraná.
