UK to Allow Imports of Diesel, Jet Fuel Refined from Russian Oil Amid Iran War Supply Crunch – Will Natural Gas Be Next?

Energy News Beat Channel | May 19, 2026

The UK government has taken a pragmatic step that highlights the tension between sanctions policy and energy reality. On May 19, 2026, it published a general trade license (effective May 20) authorizing imports of diesel and jet fuel refined in third countries from Russian-origin crude.

This is not a full reversal of Russian oil sanctions, but it formalizes access to critical refined products at a time when global supply chains are under severe stress from the Iran conflict and the effective closure of the Strait of Hormuz.

What the UK Licence Actually DoesThe General Trade Licence (GBSAN0004) under the Russia (Sanctions) (EU Exit) Regulations 2019 permits the import of specific processed oil products — diesel (commodity codes 2710 19 42 or 2710 19 44) and jet fuel (2710 19 21) — that have been refined in a third country (such as India or Turkey) from Russian crude (originating under code 2709).

It is indefinite, subject to periodic review, and applies only to these fuels. The move comes explicitly amid “disruptions to global oil production caused by the Iran war,” which has hit diesel and jet fuel supplies particularly hard.

In plain terms: Russian crude can still be refined elsewhere, and the resulting diesel or jet fuel can now legally enter the UK without falling foul of sanctions. This builds on the long-standing “refining loophole” that campaigners and analysts have highlighted for years, but now gives it explicit government backing for these key transport fuels.

The Bigger Context: Strait of Hormuz Shock

The timing is no coincidence. Following US and Israeli strikes on Iran in late February 2026, the Strait of Hormuz — through which roughly 20% of global oil and a significant share of LNG transits — has been effectively closed or severely restricted for commercial traffic.

Mines, insurance withdrawals, naval skirmishes, and Iranian restrictions have throttled flows. The result is one of the largest oil supply disruptions in decades, with ripple effects on refined products. Europe and the UK are feeling the pinch on diesel and jet fuel, exactly when seasonal demand and stockpiling pressures rise.

The UK’s license is a direct response to this crunch. It prioritizes keeping planes flying and trucks moving over strict adherence to the spirit of earlier sanctions.

Natural Gas Filling Season Begins — With Storage Critically Low

As this oil-products adjustment takes effect, Europe enters the critical natural gas injection season. European storage levels are entering May 2026 at around 31–36% full — among the lowest levels for this time of year since 2018.

Massive injections are required over the coming months to meet winter targets. The EU has already eased some fuel trajectories, but the math remains challenging, especially with reduced contributions from certain Middle East LNG sources affected by the Hormuz situation.

Russian Natural Gas and LNG: Already Flowing More Despite Phase-Out Plans

Here is where the question becomes sharp. The EU has a formal plan to phase out Russian gas:

Short-term LNG contracts are banned from around 25 April 2026.
Long-term LNG contracts phased out by early 2027.
Pipeline gas is largely gone already, with a full phase-out targeted for September 2027.

Yet reality is moving in the opposite direction in the short term. In Q1 2026, EU imports of Russian LNG hit a quarterly record of approximately 6.9 billion cubic meters — up 16% year-on-year and the highest since early 2022. Russia accounted for roughly 13–14% of EU LNG imports during this period.

Yamal LNG and other Russian cargoes have seen surges, driven precisely by the supply constraints and price spikes caused by the Iran/Hormuz crisis. Some reports describe Europe “quietly buying large amounts” of Russian LNG even as official policy pushes the other way.

The UK, by contrast, has maintained a stricter line: it banned Russian LNG imports from January 2023 and is implementing further maritime services restrictions phased through 2026.

Will the EU (or UK) Allow Russian Natural Gas “Back In”?The oil-products license shows that when supply security is genuinely threatened, governments will create carve-outs. The same logic could apply to natural gas if the crisis deepens:If alternative LNG supplies (especially from the Middle East) remain constrained by Hormuz.
If storage injections fall short and winter prices spike sharply.
If industrial demand or power generation faces real shortages.

Pragmatism has already prevailed on diesel and jet fuel. Russian LNG is already increasing in the EU despite the phase-out timeline. Long-term contracts provide a continuing channel, and spot/near-term purchases appear to be rising under crisis pressure.

However, politically, gas is more sensitive than refined oil products because of its direct link to the original Ukraine-related sanctions narrative. EU officials have publicly warned against “temptation” to reverse course, yet the data shows increased Russian LNG flows are already happening.

For the UK, a similar explicit license for Russian gas or LNG looks unlikely in the near term, given its firmer stance since 2023. But if European gas markets tighten dramatically, pressure for some form of flexibility (or tolerance of indirect flows) could grow.

Bottom Line

The UK’s decision on diesel and jet fuel is a clear signal that energy security realities are overriding pure sanctions purity when critical fuels are at risk. The Strait of Hormuz closure and Iran war have created exactly the kind of disruption that forces these trade-offs.

With the European gas filling season now ramping up against low storage levels, and Russian LNG already surging into the EU in Q1 2026, the question is no longer theoretical. Will further deterioration in supply lead to more formal or informal accommodation of Russian natural gas and LNG?

History suggests that when the lights (or the pumps) are at risk, ideology bends. Watch storage injection rates, TTF prices, and any new licensing or enforcement signals over the next 2–3 months. The gap between stated phase-out policy and actual flows is already widening.

Energy markets don’t care about political narratives — they care about molecules and molecules available at a price.
