European wheat futures have dropped to their lowest levels since April, influenced by abundant harvest supplies from the U.S. and Black Sea region, and traders' adjustments ahead of USDA crop forecasts. Euronext's September wheat fell by 1.7% to 219.50 euros per metric ton. Favorable weather conditions in the U.S. and Russia have facilitated harvesting, counterbalancing poor yields in France. Low wheat prices in Russia and Ukraine are affecting export opportunities in Sweden, where exporters are reluctant to sell despite a promising wheat crop forecast.
