Problems shipping grain through the Azov-Black Sea basin are the main obstacle for Russian exporters, according to a USDA November report cited by Kommersant. The USDA expects Russian 2026-27 exports of wheat to fall 2.5%, and corn and barley exports to fall 12.5%, as some supplies shift to the Baltic.
Lower Russian export volumes tighten global wheat, corn and barley supplies, and rerouting to the Baltic adds freight cost that supports export prices. Russia is a major exporter, so the effect on world prices is meaningful.
After 283 past bullish logistics events, Wheat (SRW) moved a median -0.2% over 5 sessions (46% higher; middle half -1.4% to +1.3%), and -0.1% over 20.
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.
