Russia's Fuel Exports Just Halved in a Year. Sanctions Are Not What Did It

Russia's seaborne exports of refined oil products fell to 3.93 million metric tons, a drop of 33.3% from June and 54.7% from the same month a year earlier. A halving of fuel exports year on year is a large number in any energy market. What makes it worth understanding is the cause, because it is not the one most readers would assume.

The figures

Refining capacity, not export policy

Sanctions on Russian energy work by restricting who may buy, at what price, and with whose ships and insurance. They constrain the transaction. This decline is upstream of any of that: drone strikes on Russian refineries have reduced the country's ability to turn crude into fuel in the first place. Refining volumes fell to 3.6 million barrels a day, the lowest since May 2022.

The distinction matters because the two causes behave differently. A sanctions restriction can be routed around — through intermediaries, re-flagged tankers, or buyers willing to accept the discount — and Russian export volumes have historically proved adaptable in exactly that way. Physical damage to a refinery cannot be routed around. Fuel that was never produced cannot be redirected to a different buyer.

Crude and fuel are not the same market

A reader tracking oil prices should be careful not to fold this into the crude story. A refinery converts crude oil into diesel, gasoline, jet fuel and other products. When refining capacity is damaged, the country produces less refined fuel — but the crude it was going to process is still in the ground or in storage, and can be exported as crude instead.

The practical effect is therefore tighter global supply of refined products, particularly diesel and gasoil, without a matching tightening in crude. That is why product markets can move independently of the headline crude price in an episode like this, and why the announced diesel and gasoil export ban matters on its own terms: it could put up to 36% of total oil product export volumes at risk, on top of a refining base already running at its lowest in four years.

Two supply shocks running at once

This sits alongside the Strait of Hormuz disruption, and the two are structurally different in a way that matters. Hormuz is a transit blockage: the barrels exist and cannot move. The Russian episode is a production loss: the fuel was never made. A negotiated reopening could restore Hormuz flows relatively quickly, whereas refinery capacity has to be physically repaired.
