Wheat prices on Euronext saw a slight increase on Tuesday due to a weaker eurodollar parity, making EU origins more competitive internationally. However, Western European wheat remains non-competitive compared to regions like the Black Sea and the Southern Hemisphere, as shown in the latest Saudi tender. There is market tension due to concerns about the Northern Hemisphere climate, particularly the cold snap affecting Russia, Ukraine, and the American Midwest, which threatens winter crops. Corn prices were mixed at mid-session, with beneficial rains announced in Argentina helping to reassure after potential losses. Euronext wheat and corn prices for future deliveries showed slight increases.
