Multiple countries brought in large grain harvests during recent growing seasons. Tanner Ehmke, the lead economist for grains and oilseeds at CoBank, said the large crops and trade tensions have led to excess grain supplies around the world. He added the theme is oversupply with record crops and record yields all over the world. "trying to find new markets is of the utmost importance. That's a challenge, obviously, when we have trade uncertainty," Ehmke said.
