Global corn prices have seen a significant decline, with Chicago corn futures reaching a three-year low and a decrease of more than 30% for the year. Factors contributing to this decline include record U.S. corn production, a large corn supply in Brazil, and the expectation of strong recovery in Argentina and Europe. Additionally, the U.S. corn export demand is growing, primarily from Mexico, while U.S. corn ethanol demand may also increase in 2024. The situation in South America will be a key variable affecting corn prices in 2024, as factors such as weather and export policies will impact the market.
