The shrinking Mississippi River has hobbled the most efficient channel for moving US soybeans onto world markets, prompting a pivot to alternatives from Puget Sound to Texas to the Great Lakes.

Typically, more than half of all US soybean exports traverse the Mississippi River but after weeks of scant rainfall, water depths have dwindled, raising barge costs to an all-time high. As a result, ports in places like southeast Texas that

normally handle less than 5% of the nations soybean exports are being thrust into action.


Its in dire condition and its getting worse, Mike Steenhoek, executive director of the Soy Transportation Coalition, said by phone. People are looking for whats their B, C and D options.

The US Department of Agriculture said 2.57 million tons of American soybeans were inspected in the week ended Oct. 27, a drop of 12% from the previous week. The Mississippi River accounted for less than a third of the shipments, with supplies also leaving ports in Alabama and elsewhere,

data showed on Monday.

At the same time, the river disruptions have increased transport costs so much that American beans and other crops are growing too expensive for some overseas buyers. Thats limiting their utility as replacements for supplies usually sourced from the Black Sea region thrown into disarray by Russias war on Ukraine.
