Russia seized three Ukrainian naval vessels attempting to enter the Sea of Azov on November 25, and tensions have continued in the Black Sea region. Disruptions to grain movement have so far been minimal.
Ukraine's Azov ports Mariupol and Berdyansk handle only a small share of its grain.
Any escalation at the Kerch Strait could disrupt Black Sea grain shipments and lift wheat and corn prices, though current impacts remain limited.
