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.
Immediate · Reported
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.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: After the EU's sixth sanctions package in June 2022 exempted pipeline crude for landlocked member states (Hungary, Slovakia, Czech Republic), the derogation was progressively gamed: refinery swap arrangements and back-to-back contracts allowed Urals barrels to enter via pipeline and free up seaborne supply for export.

The UK's third-country processing carve-out follows the same structural logic: the exemption is defined by transformation step, not by Russian revenue destination.

Counter-parallel: The 2012-2015 Iran sanctions regime included third-country processing carve-outs for petrochemical products, which OFAC later revoked when it determined that the carve-outs were supporting Iranian revenue at volumes the US had not intended. The legal precedent for revoking or tightening a third-country processing derogation exists, and OFAC's failure to issue a GL 134C successor for vessel services is a signal that US co-ordination appetite is limited.

Immediate: the UK opens a NWE demand node for Russian-derived distillate worth $1.2-1.4bn/year at 2025 volumes. For a products blender or distributor, the arbitrage exists now but the compliance window is roughly 16 days from 1 June.

Structural: if GL 134C lapses without a successor on 17 June, any UK buyer who loaded Russian-derived distillate on Western-serviced tonnage after that date faces a non-compliance position. The cost of switching to shadow-fleet tonnage for those cargoes negates most of the price advantage the UK window was intended to capture.

Consensus view: Tom Keatinge, Director of RUSI's Centre for Finance and Security, characterised the Starmer easing as an energy-security response that was poorly co-ordinated with G7 partners and out of step with Kyiv messaging. Petras Katinas at RUSI valued the flow at $1.2-1.4bn annually, placing it in the context of the UK's post-Iran-disruption jet-fuel import shortfall rather than a deliberate Russia-revenue boost.

Counter-view: The Atlantic Council's energy sanctions desk has argued consistently that third-country processing creates a legal reclassification problem: crude that enters an Indian or UAE refinery exits as a new product, and the practical enforcement gap between "Russian-derived" and "Russian-origin" fuel is too wide for unilateral UK monitoring to bridge. On this view the easing effectively reopens a revenue channel that the price cap was designed to narrow, regardless of UK intent.

Key tension: Whether the UK can credibly enforce the "derived" vs. "origin" distinction in practice, or whether the easing functions as a de facto reopening of Russian distillate revenue flows to European buyers regardless of the intermediate processing step.

Starmer reopens UK door to Russian fuel

The new buy-side window has a 17 June compliance cliff built in: Western-serviced cargoes must clear before GL 134C vessel cover lapses.

Different Perspectives

Oil traders

Sent Brent down 2.29 per cent to $98.38 a barrel on reports that mediation was reviving, moving the price on CENTCOM's quiet night rather than on Trump's same-day promise of a bigger operation with no deadline attached.

Iran

An Iranian official called the same mediation account completely misleading, denying it received any US proposal via Baghdad on the same day Iraq denied delivering one, leaving neither denial able to settle what actually passed between the two capitals.

Iraq

Called groundless the New York Times account that its prime minister carried a US ceasefire proposal to Tehran, a denial that also protects Baghdad's effort to avoid becoming a party to a war fought by aircraft it does not control.

OHCHR

Recorded 17 civilian seafarer deaths since the war began, a population neither the Pentagon nor Iran's Health Ministry counts in its own tally, and called for urgent action on 6,000 crew stranded across roughly 400 vessels in the Strait of Hormuz.

Houthis

Enforced the blockade on Saudi-linked shipping it declared on 20 July by hitting the NCC Masa and then an Aramco facility at Jazan, moving from radio warnings to strikes on land after four days without a confirmed hit.

Saudi Arabia

Struck Houthi military sites near Hodeidah the same day the NCC Masa was hit, while its coalition spokesman insisted Hodeidah, Ras Issa and Salif all remain open to navigation. The distinction protects the ports Yemen's population depends on for food and fuel even while punishing the group behind the tanker strike.
