Reuters reports that a severe Amazon drought has disrupted ship traffic near Manaus and raised costs on northern shipping routes. Officials warn that thinning rivers could disrupt grain exports from the region in the coming months.

After 285 past bullish logistics events, Corn moved a median +0.1% over 5 sessions (52% higher; middle half -1.5% to +1.5%), and +0.8% over 20.
