An NDSU crop economist explains that the USDA tracks U.S. corn and other grain use in three categories: feed, domestic processing, and exports. Feed use is hard to measure weekly, while processing is relatively stable and easier to project.
Export volumes are the hardest to forecast, and the USDA's weekly export sales and inspections reports are the main updates on them.
Export volumes are hard to predict and can shift quickly under changing trade flows, shipping disruptions or conflict. Unexpected changes in U.S. export pace in the weekly data can move grain price trends.
