Export sales for many key U.S. commodities showed big improvements during the week ending January 12th. The USDA says corn topped a million tons and sorghum hit a marketing year high, while soybeans, soybean products, wheat, beef, pork, and cotton were all above the previous week’s levels. Rice was a notable exception, notching a marketing year low. Export business is driven by several factors, including seasonal demand trends and currency trade. The USDA’s next set of supply and demand estimates is out February 8th.
