## Prediction

In the next week, Russian oil export logistics will face modest but tangible disruptions and cost increases as operators reassess the safety of shadow fleet tankers after the drone attacks near Turkey. Some vessels may seek alternative routes, flags, or insurance arrangements, and Russia may shift more volumes to pipeline routes or non-targeted carriers where possible. Freight and insurance costs for opaque, sanctions-evading cargoes will climb, narrowing netbacks for certain Russian grades. However, Moscow will likely maintain overall export volumes by reallocating flows rather than significantly curtailing output.

## Drivers

- Naval drone strikes on three Russia-linked shadow fleet tankers off Kilyos
- Emerging trend of Ukrainian economic warfare targeting Russian state capacity and logistics
- Existing vulnerability of shadow fleet due to sanctions, aging hulls, and limited insurers
