How Ukrainian drone strikes on Russian refineries and Black Sea terminals are reshaping global energy markets

Impact on exports and terminals

Seaborne fuel product exports collapsed. Russia's seaborne oil product exports fell 54.7% in July 2026 versus July 2025, to 3.93 million tonnes; average daily shipments dropped 33.3% month-on-month .

Black Sea terminals under direct threat. The Sheskharis oil terminal at Novorossiysk — which normally ships ~700,000 barrels per day — halted operations on August 14 after a drone attack, with a tanker turning away rather than docking . A major August 12 attack also hit warships and forced two grain terminals at Novorossiysk to halt .

Export capacity severely degraded. At its worst point in late March 2026, approximately 40% of Russia's oil export capacity was offline; this had improved to ~20% by early April, but the situation remains fragile . Baltic ports Ust-Luga and Primorsk have also been repeatedly hit, with 16 of 54 storage tanks at Ust-Luga destroyed during one campaign .

Domestic fuel rationing and shortages

Multiple regions imposing rationing. The Kaluga region (adjacent to Moscow) introduced license-plate-based rationing starting August 15. The Orenburg region in the Urals limits gasoline and diesel sales by plate number. Volgograd region reimposed a 40-liter-per-vehicle cap after the Lukoil refinery strike on July 31 .

Fuel queues and government interventions. Long lines at gas stations are reported across the country . Russia has allowed refineries to produce fuel with lower environmental standards to stretch supply, and Deputy PM Novak acknowledged in late July that while the market is "partially stabilizing," regional challenges persist .

Broader consequences

Global fuel supply and prices. The campaign is helping drive up world energy prices already elevated by the Iran war . The Black Sea has become "the latest strategic trade chokepoint," disrupting global grain and oil commodity flows . Russia's inability to export diesel and gasoline has tightened global refined product markets, with effects visible in the U.S. as well .

Diplomatic dynamics. Ukraine's partners (the U.S. and European allies) have asked Kyiv to reduce strikes on Russia's oil sector because the attacks were contributing to global price spikes amid the Iran conflict, according to President Zelenskyy . Ukraine has nonetheless escalated, creating a "long-range impact" command in July 2026 and showing no signs of easing the campaign . Kyiv's stated calculation is that every barrel of Russian oil not exported reduces Moscow's war revenue — even as higher global prices partly offset the volume loss .

Key uncertainty: Russia has some ability to shift crude flows through Arctic routes and to use spare refining capacity at undamaged plants, which partially cushions the blow . The long-term sustainability of the drone campaign depends on Ukraine's ability to maintain pressure faster than Russia can repair or relocate refining capacity.
