The price of corn The week ended higher on the Chicago Board of Trade, while the Brazilian market remains practically stable, but with factors that could support prices. According to data released by the International Center for Economic Analysis and Agricultural Market Studies, CEEMA, the first contract closed at US$ 4.78 per bushel on August 20, compared to US$ 4.48 a week earlier.
The weather in the United States continues to be a major point of concern. According to the International Center for Economic Analysis and Agricultural Market Studies (CEEMA), excessive rainfall in North American producing regions has influenced prices and increased uncertainty regarding productivity.
On August 16, 60% of U.S. corn crops were rated as good to excellent. At the same time last year, the index was 71%. Plant development, however, is more advanced than normal, with 76% of areas in the grain-filling stage, compared to the historical average of 70%, according to CEEMA.
Surveys conducted by the Pro Farmer Crop Tour also indicated lower yield potential in some areas. According to the International Center for Agricultural Economics and Market Research (CEEMA), the yield forecast in Indiana was 183.5 bushels per acre, compared to 193.8 last year. In Nebraska, the estimate fell from 179.5 to 163.6 bushels per acre.
The estimate for Argentine production in 2025/26 was also raised to 70.5 million tons, a volume classified as historic. The harvest reached 89% of the area, below the average of 97% for the period.
In Brazil, prices show little variation, according to CEEMA, with the main markets in Rio Grande do Sul maintaining values close to R$ 58 per sack. In other monitored regions, prices fluctuate between R$ 52 and R$ 64 per sack. Despite the stability, the market shows an upward bias. According to data released by the International Center for Economic Analysis and Agricultural Market Studies (CEEMA), international appreciation improves export parity, while the delay in the Brazilian harvest and concerns about possible El Niño effects at the end of the year remain on the radar.
