Russian refinery throughput fell to 4.69 mbpd, the lowest since December 2009; on 2-3 May Ukraine launched 334 drones into Russia against Russia's 268, the first verified overnight reversal of the daily exchange ratio.

Key takeaway

Ukraine's refinery campaign reached every leg of Russia's export chain in one fortnight and outflew Russia for the first time.

Russian average refinery throughput fell to 4.69 million barrels per day (mbpd) in late April, the lowest reading since December 2009. Tuapse refinery on the Black Sea coast was struck for the fourth time in two weeks on 1 May, with fires reigniting after the Russian Emergency Situations Ministry declared them out. Volodymyr Zelenskyy confirmed Ukrainian strikes on two Russian shadow tankers off Novorossiysk on the Black Sea coast. Ukraine's drone forces commander told Meduza on 1 May that 'no part of Russia is safe from strikes'.

On the night of 2-3 May, Ukraine launched 334 drones into Russia against Russia's 268 drones at Ukraine, the first verified overnight reversal of the daily exchange ratio. The reversal sits beside three other shifts in the same week: the move past terminals to refineries to the offloading fleet itself; the Security Service of Ukraine (SBU) Transneft-Privolga strike ; and the underlying tempo build that produced the 22 April mass-launch outlier . Ukraine has now closed every leg of the Russian export chain inside one fortnight.

Pre-war Russian refining norms ran near 5.6 mbpd; the 4.69 mbpd reading implies roughly 0.9 mbpd of lost domestic processing. Russia is fighting an offensive without the petrol and diesel volume its own forces and economy require, and with the gasoline export ban active since the Kirishi shutdown earlier in April, Moscow cannot monetise the refined-product premium when crude is rerouted to export.

CEPA (Center for European Policy Analysis) and RUSI (Royal United Services Institute) put the 2025 strike campaign at 0.46% of Russian annual oil revenue . Two changes have moved that calculus: target diversification across the export chain and the breach of the daily exchange ratio. Zelenskyy told RBC-Ukraine Russia has lost at least $7 billion since January 2026 from long-range strikes, more than fifteen times the 2025 baseline.

Deep Analysis

In plain English

Ukraine's drones and missiles have been striking Russian oil refineries and export facilities for months. This week two developments crossed important thresholds. Russian refineries are now processing oil at their lowest rate since December 2009, meaning Russia is producing less refined fuel than at any point in 16 years. Separately, on the night of 2-3 May, Ukraine launched 334 drones toward Russia overnight; Russia sent 268 toward Ukraine. That was the first time Ukraine sent more drones in a single night than Russia. The Tuapse refinery in southern Russia was struck four times in two weeks, with fires reigniting after Russian authorities said they had put them out. Ukraine also struck two Russian oil tankers off the coast of Novorossiysk, extending the campaign from refineries to the ships that carry Russia's oil to buyers.

Deep Analysis
Root Causes

The drone volume reversal has two structural causes that are separate from simple production numbers. First, Ukraine shifted manufacturing from single-mission Shahed-clone airframes to a mixed fleet of purpose-built low-observable loitering munitions with modular warheads starting in Q4 2025.

That mix allows smaller warheads at higher sortie rate, which is why Tuapse fires reignite: the warhead is sized for fuel-system ignition, not structural destruction, enabling sustained reignition cycles rather than terminal damage.

Second, Ukraine's drone corridor management has adapted to Russian EW (electronic warfare) patterns. Russian R-330Zh Zhitel EW systems were redeployed to protect Moscow oblast following the parade security decision; that redeployment thinned the EW coverage on southern corridors between Ukraine and Krasnodar Krai.

Tuapse sits in that thinned zone. The four strikes in two weeks are therefore partly a product of the same parade-security decision that produced event-00 in this briefing: redirecting EW assets to Moscow created a drone-route window in Krasnodar.

What could happen next?
  • Consequence

    The overnight drone volume reversal, if sustained over a two-week period, would force Russia to deploy more EW and air-defence assets to the interior rather than the front, reducing battlefield coverage.

    Short term · 0.68
  • Risk

    If Russia retaliates for the shadow tanker strikes with attacks on Ukrainian Black Sea infrastructure, the conflict risks drawing in Turkish and Romanian energy transit interests in the Black Sea.

    Short term · 0.55
  • Consequence

    Refinery throughput at 4.69 mbpd compresses Russia's export margin to approximately 1.5 mbpd; sustained at this level, domestic fuel subsidy costs rise and public-facing inflation pressure on the Russian government increases.

Refineries hit 16-year low; drones flip
Three indicators of the deep-strike campaign moved together: refinery throughput, the offloading fleet, and the exchange ratio Ukraine had never previously won.

NetBlocks recorded 1,704 cumulative hours of near-total internet blackout for roughly 90 million Iranians on Day 74, while IHR documented ongoing executions under emergency provisions. These organisations are the only active monitoring windows into a civilian population cut off from the global internet for 71 consecutive days.

UK / France coalition
The Royal Navy confirmed HMS Dragon's Hormuz deployment on its own website on 11 May, converting a press-reported presence into declared force posture; UK and French defence ministers hosted a coalition meeting the same day. Britain and France are now the only named contributors to a Hormuz escort mission all five allies Trump originally asked had declined.
Saudi Aramco / Gulf producers
Saudi Aramco / Gulf producers
Saudi Aramco CEO Amin Nasser warned on 11 May that a Hormuz closure could remove 100 million barrels of weekly supply from global markets (roughly 15 million barrels per day for a week), a figure that dwarfs any OPEC+ swing capacity. The warning functions as both a price-floor signal and a public pressure on Washington to protect transit.
Beijing / Chinese Government
Beijing / Chinese Government
China has not publicly acknowledged the four Hong Kong-registered entities designated on 11 May or extended MOFCOM's Blocking Rules cover to HK-domiciled firms. Xi Jinping hosts Trump on 14–15 May having already de-risked state-bank balance sheets via NFRA's quiet loan halt, entering the summit partially compliant before any negotiation.
Tehran / Iranian Government
Tehran / Iranian Government
Foreign Minister Araghchi described Iran's 10-point counter-proposal as 'reasonable and responsible' via spokesman Baqaei on 11 May, and widened the mediator pool by meeting Turkish, Egyptian, and Dutch counterparts in a single day. Tehran is buying procedural runway while Trump's verbal rejection went unmatched by any written US counter.
Trump White House
Trump White House
Trump called the ceasefire 'on massive life support' and dismissed Iran's 10-point counter-proposal as 'a piece of garbage' on 11 May, while departing for Beijing two days later with no signed Iran instrument to show Congress. The verbal maximum and the paper void coexist: the administration is running a legal pressure campaign through Treasury while the president free-lances the rhetoric.
