Leftfield Commodity Research says the Russia-Ukraine invasion halted Black Sea shipping and sharply lifted feedgrain prices across Europe, with French prices up US$90-100/t since the invasion began. Ukraine and Russia together supply roughly 30% of global barley exports, and most Ukrainian barley has already shipped.
Russian barley exports tend to be steadier through the year, so any interruption there would matter.
Disrupted Black Sea shipments and the risk to Russian barley flows keep feed grain prices elevated, especially in import-dependent Western Europe.
