Corn futures prices experienced a decline both in Brazil and the United States on February 27, 2023. In Brazil, the March/23 maturity saw a 0.40% drop to R$ 87.55, with other maturities also decreasing. This downturn is linked to the US Department of Agriculture's forecast of a larger US corn crop and concerns about demand. Additionally, concerns about an upcoming heat wave that could damage Argentina's corn crops have further pressured the international market, contributing to the price decrease observed in the Chicago Board of Trade.
