Pork export sales surged to a marketing year high during the week ending March 21st. The USDA says pork sales were driven by strong demand from Mexico, which picked up most of the week’s total, followed by Japan and Australia. Beef, corn, wheat, sorghum, soybean oil, and cotton sales also saw week-to-week improvements, while soybeans, soybean meal, and rice dipped. Export demand is driven by several factors including the value of the dollar relative to other currencies, seasonal changes in supply, and geopolitical relationships.
