Ukrainian drones kill eight in Russia and strike Wildberries warehouse, governors say
Measured from 2 Aug 2026 (event start), not the 2 Aug 2026 announcement
Oil tanker operators moved -8.6%, the largest reaction measured, though not statistically significant, meaning it may reflect normal market noise rather than the event itself. This is a provisional result; the full measurement window is not yet complete.

What Happened
Ukrainian drone strikes across Russian territory killed at least eight people and damaged Lukoil's Volgograd refinery for the second time in days, compounding fuel supply constraints within Russia. A strike also hit Wildberries, Russia's largest online retailer and logistics company, damaging a major warehouse facility. These strikes follow Ukraine's broader campaign to degrade Russian refining capacity, including operations against the Black Sea and Caspian shipping used to move crude and refined products. The cumulative effect constrains Russia's domestic fuel supply and export logistics.
Second major refinery strike in days removes processing capacity from a key non-OPEC producer and compounds logistics damage, supporting global crude prices and constraining non-Western supply sources
Strikes occurred August 1-2, 2026; ongoing campaign with no end date visible
Regional governors and Russian Defence Ministry confirmed strikes on August 2 overnight and during Sunday, with Wildberries warehouse strike explicitly documented by governors
