University of Minnesota grain economist Ed Usset says Mississippi flooding is having a limited impact on grain movement because export demand is not strong and the river situation is better than last fall. He expects the flooding to pass and suspects a modest effect on Mississippi basis prices.
Limited export urgency and a temporary flood-driven delay suggest only modest basis weakness, so the price effect on feed grains is likely small.
