Ukraine's Navy spokesperson said Russia has begun routing grain through the Arctic port of Murmansk since October 2026 because southern corridors are inaccessible. Shipping costs via Murmansk run three to five times higher than through southern ports.
Russian vessels based in Novorossiysk have avoided the open Black Sea for over five months.
Higher Russian export logistics costs and forced rerouting tighten Russian grain flows and support international wheat prices, though the effect is largely already known to the market.
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.
