Pork export sales fell to a marketing year low during the week ending May 9th. The USDA says that week-to-week dip for pork followed reductions by several key customers including Japan, Mexico, and South Korea. Old crop corn, soybean, soybean oil, sorghum, and cotton sales were also below the previous week, while wheat, soybean meal, and beef saw improvements. Export business is influenced by several factors, including the value of the dollar relative to other currencies, domestic price movement, and seasonal changes in supply.
