Great Lakes shipping season opened in March 2022 with late-season ice and snarled supply chains slowing traffic. Port of Green Bay tonnage for March and April fell 21 percent year over year, and a vessel loaded about 21,600 short tons of wheat at Superior, Wisconsin.
Slower Great Lakes grain logistics can tighten regional wheat and grain movement to export, modestly supporting local basis and freight costs.
After 163 past neutral logistics events, Wheat (SRW) moved a median +0.1% over 5 sessions (53% higher; middle half -1.3% to +1.1%), and -0.3% over 20.
