Overnight trading saw grain futures move sharply higher on drought and weather worries in major overseas growing regions like Argentina and Russia, where leaders are suspending or limiting soybean and wheat export sales to ensure adequate domestic supplies, which could up demand for U.S. grain on the global market. On top of a U.S. Dollar Index that continues to trend lower, this means U.S. grain could be a good deal for export buyers who have already begun ramping up purchases, according to the latest USDA grain export sales data. Grain prices also have upside potential from the continued drought conditions in the U.S., which could limit crop output in the coming year. See more analysis on the grain markets to start the week.
