EuroOilWatch Analysis — a follow-up to Russia Is Importing Fuel While Exporting Crude: what the fourth supply route tells you that the first three did not.
A small cargo with a long shadow
The volume is almost trivial. Roughly 30,000 tonnes of AI-92 petrol — on the order of a quarter-million barrels — loaded at Tangier in mid-July aboard a Panama-flagged tanker, and discharging at Murmansk, Russia's Arctic port, on 31 July. Two industry sources told Reuters that Lukoil acted as the supplier; the company did not comment. Against a country's fuel consumption, one cargo is a rounding error. Nobody is rescued by it.
That is precisely why it deserves attention. Nations do not move trivial volumes of fuel along implausible routes for fun. A cargo like this is procurement at the margin — and the margin tells you where a system actually stands, in a way headline statistics cannot. Russia's petrol production had fallen to about 65% of normal summer consumption by early July (Reuters), and Reuters has reported plans to import as much as 400,000 tonnes a month from various countries. The statistics say "strained." The Tangier cargo says how strained: strained enough that a parcel of petrol is worth carrying from the Strait of Gibraltar, north along nearly the length of Europe's Atlantic seaboard, to the Arctic.
One point of precision before anything else. Morocco has not operated a refinery since SAMIR, at Mohammedia, shut in 2015 — it remains in liquidation, and a proposal to nationalise and restart it was rejected by Morocco's upper house in June. This was therefore not Moroccan-refined petrol. It was imported or transshipped product loaded through Tangier's large refined-fuels terminal — 532,000 cubic metres of storage across 19 tanks, built for exactly this import, export and transshipment trade — and its original refinery and barrel provenance have not been disclosed.
That makes the signal sharper, not weaker. Russia has not found a new refining nation willing to supply it. It has reached into a third-country storage and trading hub for petrol of undisclosed origin.
Read the supply routes as an instrument
When we published Russia Is Importing Fuel While Exporting Crude on Monday, the routes were Belarus, Kazakhstan and India. Each carried different information, and the sequence matters.
Belarus was the easy reading. A union-state neighbour and established rail supplier — more than 70,000 tonnes in the first half of June alone. Buying from Minsk is barely importing at all.
Kazakhstan was the emergency reading. A neighbour that normally depends on Russian fuel, sending an emergency shipment back north — the first confirmed July cargo only around 1,000 tonnes. The direction of flow, not the volume, was the message.
India was the structural reading. Russian crude sails east to Indian refineries; petrol shipped from India — at least 60,000 tonnes by early July, through traders, with the supplying refiner unclear — comes back. The round trip put a price on the difference between owning feedstock and owning conversion capacity: the thesis of the original piece in a single trade route.
Tangier is the transshipment reading. No shared border, no integrated regional fuel system, and no previously established role in Russia's emergency petrol supply. What is established is that a Russian oil major obtained petrol through a North African logistics hub and moved it from Gibraltar to Murmansk. When procurement reaches this far down the list of convenient options, it means the convenient options are exhausted or maxed: the neighbours are giving what they can, the Indian arbitrage is already running, and the marginal tonne must now be found wherever the global trading system has one in a tank.
Each route is a depth-gauge mark. Four routes in, the gauge is well below any line Moscow would have considered thinkable in June.
Why the gauge keeps dropping
The underlying damage has not stopped accumulating, and this week compressed it: the Ryazan refinery halted crude processing entirely after a drone strike, with industry sources telling Reuters roughly two weeks of downtime, and Lukoil's Perm refinery — about 260,000 b/d in total — lost a crude-distillation unit to a drone-triggered fire. A further drone attack set an unidentified energy facility and warehouses ablaze in the Volgograd region; as of 31 July, Reuters had not confirmed that the refinery there was itself struck, and we do not claim it. Diesel and gasoil loadings had already collapsed to about 234,000 b/d in early July, against a 2025 average near 817,000.
Moscow's own instruments read the same way. Fuel-export restrictions have been extended through 31 January 2027 — a six-month horizon — and the measure is strongest exactly where the shortage is: petrol. From 1 September, producers are again exempt when exporting diesel, marine fuel and gasoil, and intergovernmental and humanitarian shipments continue. Even with those qualifications, extending restrictions while simultaneously widening petrol imports is a plain indication that domestic supply remains under pressure. The policy and the procurement are two halves of one admission.
Why this reaches Europe
This is not only a Russian curiosity, but the transmission needs stating precisely — because it is not molecule-for-molecule.
Russia and Europe are not competing for the same product. Moscow's immediate shortage is petrol; Europe's sharper vulnerability is diesel, with European diesel inventories at their thinnest since 2022 and total independently held product stocks in the ARA hub at a 2014 low. A tonne of gasoline diverted toward Murmansk does not directly remove a tonne of European diesel.
But both shortages are drawing on the same constrained global refining and trading system — the one setting record diesel margins and near-record gasoline margins at once, with European petrol's premium to Brent at $42.21/bbl on 29 July, close to mid-July's four-year high of $44.94. Into that system steps another urgent, price-insensitive buyer — one that used to be a major seller. Refinery capacity, shipping and product inventories are shared plumbing; a new draw anywhere raises the pressure everywhere. The pool does not care whose shortage is whose. It simply reprices.
The honest limits
Three restraints, as ever. The volumes are marginal — emergency procurement, not a new trade structure, and one cargo does not make a trend; it is the fourth route that makes the pattern. This is not collapse — Russia is managing a chronic degradation with rationing, redirection, bans and imports, exactly as we wrote on Monday; "difficult," in Deputy PM Novak's word, still is not "failing." And the cargo's provenance — which refinery made it, whose barrels it originally was — is not public; what is established is the loading point, the route, and the reported supplier.
What is established is enough. In June, the idea of a petrol cargo steaming from Tangier to Murmansk would have read as satire. In August it is logistics.
The original piece ended: it is exporting crude and importing fuel — once you see why those two facts sit together, you understand the whole campaign. The Tangier cargo adds the corollary. The statistics say Russia's refining system is strained; the cargo shows the form the strain has taken — not simply buying more from neighbouring systems, but pulling petrol of undisclosed origin through a North African transshipment terminal and carrying it from Gibraltar to the Arctic.
You can watch the campaign work in real time, one route at a time. When the next improbable loading point appears, you will not need a satellite photograph of a burning refinery to understand what it means.
