Splash 247 · Aug 13, 2026
Russia and Ukraine have traded some of the heaviest blows against each other’s maritime infrastructure of the four-and-a-half-year war, pushing the Black Sea’s grain trade deeper into the firing line.

Black Sea calls have been separately listed and priced by war-risk underwriters, independently of the physical state of the straits themselves.

Global chokepointTurkey / Black SeaThe Black Sea's only outlet, running through the middle of Istanbul. It carries Russian and Caspian crude out and a large share of the world's traded grain — an agricultural corridor and an energy corridor in the same water.
- Transit is governed by the Montreux Convention rather than commercial terms, so access questions here are diplomatic events with freight consequences.
- Black Sea grain export capacity depends on this passage; disruption reaches food import bills in North Africa and the Middle East, not just shipping costs.
- Fog and current closures are routine and self-clearing. The tell for a real disruption is a change in war-risk listing or insurance availability, not a queue.
