LONDON, July 11 — The Black Sea Grain Initiative, the UN-brokered agreement that once promised to stabilise global food markets, is now a case study in geopolitical risk. Signed on July 22, 2022, it brought together Russia, Ukraine, Turkey, and the United Nations to create a safe corridor for Ukrainian grain exports. By July 2023, the initiative had facilitated the export of over 32 million metric tons of grain and foodstuffs.
That sounds like a success story. The catch is that Russia withdrew from the deal on July 17, 2023, and the entire architecture collapsed.
Ukraine responded by establishing its own maritime corridor along the coast of Romania and Bulgaria. By August 2024, that route had moved 13 million tons. It was a pragmatic workaround, but it did not restore the scale of the original deal.
The real disruption, however, may be yet to come. On August 18, 2024, a strike hit 21 Russian tankers.
The subsequent halt of shipping through the Kerch Strait could now disrupt Russia’s own grain and oil exports. The Kerch Strait is a key route for Russian grain exports from ports like Rostov-on-Don and Novorossiysk. If that chokepoint stays closed, the effect on global prices is not theoretical.
The mechanism of the original deal
The initiative was never a charity project. It was a carefully calibrated arrangement that allowed Russia to export its own grain and fertiliser while Ukraine moved its harvest. The UN negotiated the terms, Turkey provided the naval oversight, and both sides agreed to a set of inspection protocols.
On closer reading, the agreement always had a fragile quality. It depended on Russia’s willingness to cooperate, and when Moscow decided the deal no longer served its interests, it walked away.
The 32 million tons moved under the initiative went primarily to developing nations in Africa and the Middle East. Those are precisely the regions the UN now says are most at risk.
The new corridor and the Kerch Strait
Ukraine’s alternative corridor hugging the Romanian and Bulgarian coasts was a tactical improvisation. It worked, but at a lower volume. The 13 million tons moved by August 2024 represents a significant drop from the original pace.
Then came the strike on the 21 Russian tankers. That event has effectively shut down shipping through the Kerch Strait, which is not just a route for military vessels — it is a commercial artery.
Russian grain exports from Rostov-on-Don and Novorossiysk depend on that passage. If those shipments stall, the global supply of grain tightens. The UN has expressed concern about the impact on global food security, particularly for developing nations in Africa and the Middle East that rely on Black Sea grain.
The mechanics here are simple: less supply means higher prices. The question is whether the Kerch Strait disruption will compound the damage already done by Russia’s withdrawal from the original deal.
The UN is watching closely. So are the governments of countries that depend on affordable grain imports. The next few months will show whether the Black Sea can sustain two separate, fragile shipping arrangements — or whether the region’s grain trade is now permanently hostage to the conflict.
