Only two Mississippi River locks reported grain barge traffic in the latest reporting week. Year-to-date grain shipments are down nearly 30 percent from the three-year average, and spot barge rates for export grain have fallen for three weeks as shippers avoid high water.
Lower barge demand signals reduced river movement of grain, which weakens Gulf export basis and pressures interior cash prices, though falling barge rates reflect the lack of traffic rather than a rise in capacity.
