Grain markets fell to finish September on warm weather, harvest pressure and near-record low Mississippi River levels. The river at Memphis was within 2.3 inches of its record low and expected to stay there for weeks.
USDA reports also showed more hard red spring wheat than previously estimated.
Low river levels restrict barge loadings for about 60% of U.S. grain exports and raise transport costs, making U.S. grain less competitive abroad. This weighs on U.S. wheat values and lifts barge freight rates.
After 137 past bearish logistics events, WHEAT moved a median -0.3% over 5 sessions (44% higher; middle half -2.2% to +1.0%), and +0.0% over 20.
