A study by economists James Mitchell and Hunter Biram estimates Arkansas's 2022 soybean crop lost up to $293 million in value due to low Mississippi River levels. Memphis gauge readings reached minus 10.8 feet in October 2022 and a record minus 12 feet a year later.
Barge draft restrictions and reduced tows limited commodity movement.
Draft limits and fewer barges reduce river capacity and depress local soybean cash prices relative to futures. Recurring low water makes these basis and freight costs a repeated feature of the harvest.
After 363 past bearish weather events, Soybeans moved a median -0.6% over 5 sessions (42% higher; middle half -2.5% to +1.1%), and -0.2% over 20.
