The USDA's latest grain export sales report, released on June 16, shows mixed results with mostly disappointing performances. Soybean sales are showing relative strength despite tighter domestic supplies, while old crop corn sales have dropped to a marketing-year low. Wheat sales are also underperforming. Corn export shipments have decreased by 10% from the average, with Mexico as the top destination. Soybean exports have increased by 23% from the average, with Mexico being the leading recipient. Wheat export shipments were 13.6 million bushels last week, reaching the lower end of analyst expectations.
