Russia and Ukraine struck 317 merchant and other vessels in the Black Sea and Sea of Azov between May and October 2026, more than four times the previous six months. Almost no merchant ships have called at Ukrainian ports since late July, and a maritime truce is seen as the only likely route to resuming trade.
Sustained drone attacks on shipping keep Black Sea grain and oilseed exports constrained, which supports global wheat, corn and vegetable oil prices and keeps buyers reliant on alternative origins.
