ISTANBUL, July 9 — Against this backdrop of a war that has reshaped global trade routes, the Black Sea remains a critical artery for food security, and Ukraine’s ability to move grain to world markets is once again in focus. Before the 2022 invasion, Ukraine historically exported 45 million tons of grain annually. The Black Sea grain initiative, brokered by the United Nations and Turkey in July 2022, provided a diplomatic lifeline, allowing the safe passage of 33 million tons of grain over one year.
That corridor collapsed when Russia withdrew in July 2023, leaving Ukraine to forge its own path. Following Russia’s withdrawal from the UN-brokered deal, Ukraine established a temporary maritime corridor along the western Black Sea coast.
This route, protected by naval drones and coastal anti-ship missiles, became the new lifeline for Ukrainian agricultural exports. What is at stake is not merely a matter of trade, but the economic survival of a nation at war. Ukraine’s agricultural sector accounts for 10% of its GDP and employs 14% of its workforce.
The ability to export grain is also a key source of foreign currency, with agricultural exports totaling $21 billion in 2023. According to the Ukrainian Ministry of Agrarian Policy, in the first half of 2024, Ukraine exported 26 million tons of grain via this temporary corridor.
That figure, while substantial, still falls short of pre-war export volumes, and the route remains vulnerable to Russian naval power. The August 2024 strikes on Russian naval vessels were a direct response to this vulnerability. The operation aimed to further secure the corridor by reducing the threat of Russian blockade and amphibious assault.
For Ukraine, controlling the western Black Sea is not an abstract strategic goal; it is the difference between grain reaching global markets or rotting in silos. The wider picture involves global food prices and the stability of import-dependent nations across the Middle East and Africa. Before the war, Ukraine was a dominant supplier of wheat, corn, and sunflower oil to these regions.
Every disruption in the Black Sea sends ripples through commodity markets. Turkey, as the broker of the original grain deal, remains a pivotal player.
The Bosporus and Dardanelles straits, which Turkey controls under the Montreux Convention, remain the chokepoint through which all Black Sea grain must pass. For now, Ukraine’s temporary corridor is operational, but it is not a permanent solution. The threat of Russian naval assets, even after the August 2024 strikes, has not been eliminated.
What is at stake is the continued flow of 26 million tons of grain per half-year — a volume that feeds millions and sustains Ukraine’s economy. Looking ahead, the durability of this corridor will depend on Ukraine’s ability to maintain its defensive posture in the Black Sea, and on the diplomatic support of allies who understand that food security is a weapon of war.
The wider picture remains uncertain, but the facts on the ground are clear: Ukraine is exporting grain, but the route is fragile, and the war is far from over.
