Ukrainian wheat exports fell almost 25% in December as Russia intensified attacks on Ukraine's port infrastructure. Corn exports dropped about 13%, and total Ukrainian grain exports fell 16% year on year.
Reduced Ukrainian port throughput tightens near-term Black Sea supply for feed corn and wheat, supporting prices, though buyers can substitute from other origins.
After 323 past bullish geopolitics events, Corn moved a median +0.5% over 5 sessions (57% higher; middle half -1.5% to +2.9%), and +0.9% over 20.
After 361 past bullish geopolitics events, Wheat (SRW) moved a median +0.7% over 5 sessions (58% higher; middle half -1.4% to +3.7%), and +1.3% over 20.
