The USDA has revised corn production forecasts, reducing estimates for Ukraine, Mexico, and South Africa, but increasing them for Argentina. This has resulted in a surge in corn futures on the Chicago and Paris exchanges. Despite a lower predicted harvest, Ukrainian corn remains the most affordable globally, leading to increased exports. The forecast for Brazil remains unchanged due to favorable weather conditions for second-crop corn. However, if South American weather continues to support crop development and harvesting, prices may remain under pressure due to high supply volumes.
