Starmer reopens UK door to Russian fuel

The Starmer government eased UK sanctions around 21 May to permit imports of jet fuel and diesel refined from Russian crude in third countries. RUSI values the flow at $1.2-1.4bn a year and its own director called the move an embarrassment for Downing Street.

Key takeaway

The new UK window for Russian-derived distillate has a 17 June compliance clock built in.

The Starmer government eased UK sanctions around 21 May to permit imports of jet fuel and diesel refined from Russian crude in third countries 1. RUSI (the Royal United Services Institute) valued the flow at $1.2-1.4bn a year at 2025 volumes, per research fellow Petras Katinas. Tom Keatinge, director of RUSI's Centre for Finance and Security, called it an embarrassment for Downing Street, poorly communicated and out of step with the messaging to Kyiv 2.

The mechanism that matters here is vessel-services compliance, not the flat price. GL 134C (General License 134C), the insurance, crewing and classification cover OFAC reinstated on 18 May , runs only to Wednesday 17 June and eased the compliant-tonnage squeeze on Baltic Aframax freight when it landed . Once it lapses without a successor instrument, and OFAC had issued none as of 1 June, Western-serviced tonnage carrying Russian-derived distillate to UK ports goes non-compliant.

For a products desk the buy-side window opens with roughly two weeks of clean logistics inside it. Any blender or distributor leaning on the new UK node has to load and have cargoes in transit before the cover cliff. London frames the easing as energy security, since the Iran conflict knocked out jet-fuel supply chains and import cover came first. The policy and the 17 June cutoff pull in opposite directions, and an unco-ordinated UK move complicates G7 price-cap alignment heading into Kananaskis.

Deep Analysis

In plain English

Britain quietly changed its rules around 21 May to allow the import of jet fuel and diesel that was made from Russian crude oil, as long as the refining was done in a third country such as India. The move is worth over a billion pounds a year in fuel that would not otherwise come into the UK. The catch is a separate US licence called General License 134C. That licence lets Western shipping companies, insurers, and crew legally handle cargoes connected to Russian oil. It expires on 17 June. Once it lapses, Western-crewed and Western-insured ships cannot carry those cargoes to UK ports without breaching US rules. So the UK opened a door that has a built-in padlock sixteen days away.

Deep Analysis
Root Causes

The Hormuz disruption stripped roughly 695kbd of EU gasoil imports in April 2026 (per ) and hit UK jet-fuel supply chains at the same time BP Rotterdam's 400kbd refinery was offline for maintenance (per ). The Starmer government's energy-security rationale is structurally coherent: the UK jet-fuel import deficit was real and the domestic production capacity to fill it was offline simultaneously.

The compliance constraint runs through GL 134C, which authorises vessel-services cover for Russian-origin cargoes loaded by 17 April but expires 17 June. The UK's new buy-side window is operationally dependent on that umbrella for any buyer using Western-serviced tonnage. The policy and the licence calendar were written on different desks, creating a self-limiting two-week compliance window that the UK government did not publicly acknowledge.

What could happen next?
  • Consequence

    UK buyers using Western-serviced tonnage for Russian-derived distillate must complete cargo loading and transit before the 17 June GL 134C lapse or face non-compliance.

  • Risk

    An unco-ordinated UK move complicates G7 price-cap alignment heading into the Kananaskis summit on 12-15 June, where EU-27 unanimity on a full maritime-services ban is the deferred agenda item.

  • Precedent

    The UK's third-country processing carve-out establishes a template other G7 members under domestic supply pressure could cite if their own energy-security needs intensify post-Hormuz.

UKMTO logged six armed men boarding a tanker 136 nautical miles east of Al Mukalla on 20 August and redirecting it toward Somalia. A vessel steered toward the Somali coast reads as an attempted seizure, a distinct hazard from the stand-off strikes the same lane has seen before.

Iran's Majlis speaker received Iraq's Hormuz carve-out request in Baghdad on 19 August, a request that treats passage as Tehran's to grant. Ghalibaf's authority over that grant sits alongside the Revolutionary Guard's separate transit rules, which have moved independently of Iran's foreign ministry before.

Iraq's parliament speaker asked Iran for special consideration on Iraqi Hormuz oil exports during Ghalibaf's 19 August Baghdad visit. Iraq presses the request from a weak position: Iran's central bank is simultaneously demanding Baghdad release Iranian reserves parked in Iraqi accounts.

Switzerland's economics ministry updated the Article 21 forms governing lawful Iran money transfers on 19 August, with only the revised forms accepted from 26 August. Bern operates one of the few remaining legal Iran payment channels and has just set a hard cutover on its control point.

Japan's foreign minister said in Muscat on 20 August that Tokyo wants closer coordination with Oman on safe Hormuz and Bab el-Mandeb passage. Japan has no naval presence of its own in the strait, so it is routing the ask through the state negotiating with Iran instead.

Oman's foreign minister joined Japan's in Muscat on 20 August to call for intensified coordination on Hormuz and Bab el-Mandeb navigation. Oman also runs the mediation track with Tehran, so the appeal travels through the same channel as the negotiation.
