Grain markets closed the week with significant gains as cold weather across North America coincided with a surge in export activity. Corn futures for March settled 6.5 cents higher at 430'4, while March Soybeans gained 3.75 cents to end at 1067'6, marking the highest weekly close since December. Chicago Wheat futures for March also saw strong performance, rising 14 cents to settle at 529'4. This rally across the grain complex was supported by a delayed USDA export sales report which revealed the largest weekly corn export volume in at least 25 years for sales not involving China, totaling 4.011 million metric tons. In addition to the record corn figures, soybean sales reached 2.45 million metric tons and wheat net sales hit 618,000 metric tons, both of which were at or above the high end of market expectations. Traders continue to monitor weather patterns closely, as recent precipitation in northern production areas of Argentina has caused a slight slowdown in their harvest progress.
