The primary driver was not voluntary compliance but war. Ukrainian forces struck Russia's oil production, storage, and pipeline assets persistently throughout July, directly forcing lower crude extraction . This marked a dramatic reversal: prior to the intensified campaign, Russia had often exceeded its quota; the deep undershoot represented a war-related disruption rather than a policy choice .
The campaign against Russia's refining capacity has been even more damaging than the production hit. Ukraine has struck at least 24 of Russia's 34 largest refineries in roughly 50 attacks . The Moscow refinery — the largest fuel supplier to the capital — suffered two drone strikes in June 2026 and was knocked offline for at least six months .
By early July 2026, the Ukrainian General Staff estimated that 43% of Russia's refining capacity was offline, with later monitoring data showing it slumped to its lowest level in 21 years, at 3.91 million barrels per day . The results for Russia's domestic fuel market were swift and severe:
While Russia's output cratered, the picture among its OPEC+ allies looked very different. Iraq, Saudi Arabia, and Kuwait sharply increased their own production in July 2026:
The result: Gulf states largely compensated for war-related disruptions elsewhere, while Russia — constrained by Ukrainian strikes — could not raise its own output to fill the gap. This widened the production disparity within OPEC+, with Russia falling far short of its quota even as Gulf allies ramped up toward or above theirs .
