Black Sea grain corridor opens — Key Events — Ukraine–Russia

What happened

A UN- and Turkey-brokered arrangement restarts Ukrainian maritime grain exports; after Russia's 2023 exit, Ukraine forces its own corridor open by pushing back the Black Sea Fleet.

Global food prices, Black Sea insurance markets and Ukraine's export economy all hang on this corridor — the war's clearest conflict-to-market channel.
