Soybean prices in Chicago experienced a slight decrease due to the progress of the harvest in Brazil. The advance of the Brazilian soybean crop was raised by 15.4%, and in Mato Grosso, the advance was over 60.03%. Inflation and the decrease in oil also played a role in the market's downward pressure. China is focusing its interest on the ports of the main soy producer, which may lead to a decrease in interest in American terminals.
