Alexander Novak, Russia's Deputy Prime Minister for energy, acknowledged on 4 June that Ukrainian drone strikes are cutting the country's oil output, the first such public admission from Moscow. He cited the Yaroslavl refinery, a 300kbd plant struck in May. Russia's jet-fuel export ban runs to November 2026 and its gasoline export ban has held since April, both signs of a domestic supply system under strain.
The admission carries weight precisely because Moscow has spent months denying the strikes bit. A government that downplays damage as policy does not concede output loss lightly, so the statement reads as confirmation that the refinery campaign is reaching production rather than only headlines. Lower Russian throughput tightens an already discounted Urals grade and the distillate that flows from it.
European refiners eased back into Russian-derived distillate when the UK reopened that import window around 21 May , and the Druzhba southern leg restart had been feeding MOL and Slovak refiners discounted crude . Novak's admission means that supply is degrading just as those buyers leaned on it, and the same 17 June waiver clock threatens to shut the window entirely. Falling Russian product against elevated Brent is the worst pairing for Mediterranean refinery margins.
