Sub-zero temperatures and ice have slowed barge operations on the Mississippi River in December, according to USDA data. Lower river levels in the lower system are hovering just above the low threshold, and warmer weather is expected to melt some ice.
Barge delays and low water tighten river logistics, raising freight costs and supporting Gulf basis for corn and soybeans.
After 1,465 past bullish weather events, Corn moved a median +0.2% over 5 sessions (54% higher; middle half -1.4% to +1.9%), and +0.9% over 20.
After 1,079 past bullish weather events, Soybeans moved a median +0.3% over 5 sessions (54% higher; middle half -1.4% to +2.0%), and +0.9% over 20.
