## Prediction

In the next seven days, Ankara will pursue shuttle diplomacy on a new Black Sea grain corridor while simultaneously pressing Kyiv for assurances or targeting changes after Ukrainian drones hit two Turkish-operated vessels. Turkey will leverage its NATO status and control of the Bosporus to extract concessions from both Russia and Ukraine, but missteps could see Ankara quietly slow-roll Ukrainian maritime operations or inspections. Successful talks would lower war-risk premiums on Black Sea shipping and curb global grain prices; failure or further incidents involving Turkish-linked ships would deepen fissures inside NATO and prolong elevated freight and insurance costs. Confirmation would be trilateral meetings and draft corridor frameworks or, negatively, Turkish naval escorts with stricter rules of engagement around Ukrainian drones.

## Drivers

- Reports that Turkey is mediating a new grain corridor while protesting Ukrainian drone strikes on Turkish-operated ships
- Existing estimate of 90–95 million tons of grain and oilseeds trapped in ports
- Turkey’s strategic interest in positioning itself as a maritime security provider
