# Low Water on U.S. Rivers Disrupts Grain Exports, Raising Costs for Ag Supply Chains - Agrolatam

> Low water on the Mississippi and Illinois rivers, worsened by wintry weather, has sharply restricted barge traffic for US grain shipments. The Mississippi at St. Louis fell below the 3.2-foot low threshold on Jan. 20-21, reducing draft capacity, raising transport costs and forcing export reroutes. The report says the situation comes amid strong global demand for corn, soybeans and wheat.

## Why it matters

Higher barge costs and reduced draft widen the discount on interior grain versus Gulf export values, which pressures farm-level prices for corn and soybeans while shifting export flows.
