## Prediction

Over the next seven days, continued Russian Geran drone strikes on vessels and incursions into Romanian airspace are likely to force a partial de facto blockade on Ukrainian grain and product shipping, as insurers and operators increasingly avoid the western Black Sea corridor. Ukraine will lean more heavily on Danube river ports and overland rail, raising costs and reducing export volumes. NATO will intensify air policing and maritime surveillance, increasing the risk of close encounters or accidents with Russian assets. Confirmation would be a measurable drop in ship traffic to Odesa-region ports, rising war-risk premia, and more frequent drone–ship contact reports; denial would be a negotiated or tacit reduction in Russian attacks accompanied by stable shipping volumes.

## Drivers

- Russian Geran-4 strike on a ship off Serhiivka
- Multiple reports of Geran-2 drones repeatedly violating Romanian airspace
- Escalation trend: Russian Black Sea warfare shifting toward maritime interdiction and UAV ship attacks
