After Russia’s full-scale invasion in February 2022, ships used to export grain from Ukraine’s Black Sea ports stopped traveling there because they were liable to be attacked by Russian forces, which suspected them of carrying military supplies.

That caused grain prices to soar to record levels and sparked fears of famine in countries in the Middle East and Africa that had previously imported Ukrainian grain, especially wheat.

Eventually, in July 2022, Russia agreed to give ships traveling to and from Ukraine safe passage, on the condition that Russian officials could inspect them. During the 11 months that the Black Sea Grain Initiative was in effect, Ukraine exported 33 million tons of grain and world food prices declined by approximately 20%. According to the United Nations, 57% of the exported foodstuffs went to developing countries.
