The UK government has loosened strict sanctions on Russian oil refined into diesel and jet fuel in third countries as prices rise.
The waiver begins on Wednesday and reflects growing supply concerns over certain fuels due to the effective blockade of the key Strait of Hormuz waterway since the start of the US-Israel war with Iran.
Some sanctions on the transport of Russian liquefied natural gas (LNG) were also lifted.
The government said that overall sanctions had got tougher but extra flexibilities were required. A similar move by the US was widely criticised.
European jet fuel prices more than doubled after the war started but are now around half higher while UK pump prices continue to rise.
According to motoring firm the RAC, the average price of unleaded petrol reached 152.52p a litre on Monday, the highest since the start of the war.
Several airlines operating in the UK and around the world have cancelled flights and raised prices in response to sky-high jet fuel prices.
For years the UK led international efforts to put economic pressure on Russia for its war on Ukraine.
Only on Tuesday it signed a G7 statement reaffirming its "unwavering commitment" to impose "severe costs" on Russia.
Since October the UK had banned the import of diesel and jet fuel refined from Russian crude oil in third countries.
Easing sanctions now will effectively allow imports of jet fuel from India, which was previously a key supplier to UK and Europe. A lot of Russian crude is also refined in Turkey.
The new rules for sanctioned processed oil products will be of "indefinite duration", though they will be reviewed periodically and may be amended or revoked, the government said.
The UK also issued a time-limited licence covering the maritime transportation of LNG and related services under Russia sanctions rules, running until 1 January.
Earlier this week, the US extended a similar waiver, first introduced in March, which loosened sanctions preventing other countries buying Russian oil and petroleum already loaded on vessels at sea.
US Treasury Secretary Scott Bessent said in March the "short-term measure" was aimed at promoting "stability in global energy markets".
The policy has been criticised by many US and UK allies who say it helps the government of Russian President Vladimir Putin and his full-scale invasion of Ukraine, which has been ongoing since 2022.
French President Emmanuel Macron has said that the Strait of Hormuz's shutdown "in no way" justified lifting the sanctions on Russia while Ukraine's President Volodymyr Zelensky has said "every dollar paid for Russian oil is money for the war".
However, UK Foreign Secretary Yvette Cooper refrained from criticising the US decision in March, describing it as a "specific, targeted issue".
A UK government spokesperson said on Tuesday it had "introduced a range of new prohibitions under the Russia sanctions regime".
"This includes further export and import bans against Russia, including restrictions on the sale of refined oil products derived from Russian crude oil and the import, supply and delivery to third countries of Russian uranium," they added.
"These sanctions also include a maritime services ban on Russian LNG. This will gradually restrict Russia's access to the UK's world-leading shipping and insurance services, disrupting their ability to transport Russian LNG.
"We are committed to strengthening our sanctions on Russia to degrade its ability to wage war in Ukraine, whilst protecting critical supply chains and maintaining market stability."

"Short-term supply relief masks longer-term erosion of sanctions leverage that could sustain elevated energy price volatility."
The UK's indefinite waiver on Russian-derived jet fuel and diesel imports, plus the time-limited LNG maritime licence to January 1, directly addresses supply shocks from the Hormuz blockade that doubled European jet fuel prices. This eases immediate pressure on UK petrol at 152.52p/litre and airline costs but signals eroding sanctions credibility after the G7 pledge. Energy markets may see short-term price stabilization while second-order risks rise: prolonged Ukraine funding via Russian revenues and potential retaliation that disrupts other flows. LNG shipping services could benefit from the carve-out, yet overall volatility in refined products persists beyond the review period.
The policy may actually reinforce sanctions effectiveness by preventing domestic fuel crises that could force broader policy reversals, preserving political support for tighter measures over time.
"The UK's 'indefinite' waiver on Russian refined fuels signals the sanctions regime is cracking under supply pressure, likely encouraging similar moves by other allies and reducing Russia's long-term cost of circumvention."
This is a tactical retreat dressed as pragmatism. The UK is easing sanctions on Russian refined products (diesel, jet fuel via India/Turkey) and LNG transport to manage near-term energy prices—a legitimate supply shock from Hormuz disruption. But the move signals sanctions fatigue and creates arbitrage: Russia redirects crude to third-country refineries, laundering it back into Western supply chains. The 'indefinite duration' language is the tell—this isn't temporary. The contradiction is stark: G7 statement Tuesday reaffirms 'severe costs,' Wednesday they loosen them. Zelensky's critique ('every dollar is war funding') has teeth. Energy prices may stabilize short-term, but this erodes the sanctions regime's credibility and gives Russia a playbook for future negotiations.
Energy security is not a moral luxury—blackouts and fuel rationing impose real costs on civilians and economies, potentially weakening Western resolve more than a controlled waiver does. If Hormuz stays blocked for 12+ months, the UK faces a choice between sanctions purity and economic crisis; choosing the latter first may be rational.
"The UK government is prioritizing short-term domestic inflation control over the long-term efficacy of its geopolitical sanctions strategy."
This pivot signals that the UK’s 'unwavering' sanctions regime has hit a hard ceiling defined by domestic political survival. By authorizing imports of Russian-origin fuels refined in India and Turkey, the UK is effectively outsourcing its energy security to shadow fleets and middlemen. While this eases inflationary pressure on UK pump prices and jet fuel, it creates a dangerous precedent of 'sanctions-lite' that undermines the G7’s credibility. The market should interpret this as a tacit admission that Western energy infrastructure cannot withstand a prolonged blockade of the Strait of Hormuz without Russian supply. Expect volatility in energy-heavy sectors like airlines (IAG, EasyJet) as they navigate this temporary supply relief against geopolitical instability.
The move might be a pragmatic, temporary tactical adjustment to prevent a catastrophic supply shock rather than a long-term erosion of the sanctions regime, potentially preventing more severe economic contraction.
"The waivers risk eroding sanction credibility and could monetize refined Russian flows enough to fund the war unless enforcement is tight and rollback is credible."
The UK move signals a pragmatic tilt: keep pressure on Moscow while averting sudden energy shocks by letting refined Russian products flow via third countries. The wrinkle is that the narrative of 'tough sanctions' remains intact—the waivers are highly conditional, time-bound in practice (LNG license to Jan 1, periodic reviews), and backed by allied criticisms. The real market impact hinges on volumes and enforcement: if Indian/Turkish refiners ramp up imports, Russia gains a new revenue channel even as headline restrictions stay on the books. Absent credible enforcement, it’s more about political signaling than material pressure relief for Ukraine.
The waivers are narrow and time-limited; the core sanctions remain in place, so the practical effect on Russia’s revenue is likely modest and the coalition can still tighten controls if needed. The market has probably priced in some flexibility, reducing the likelihood of a dramatic policy shift.
"Review mechanisms may preserve sanctions leverage while creating reversal risk for IAG and EasyJet margins."
Claude underestimates the conditional nature of these waivers. Periodic reviews tied to supply conditions give the UK an exit ramp to tighten rules once alternative non-Russian jet fuel sources come online from the Middle East. The overlooked connection is with airline stocks: while IAG and EasyJet gain short-term cost relief, any reversal after January could trigger sharper volatility in their margins than current models price in.
"Periodic reviews create the illusion of conditionality; political economy favors indefinite extension once supply stabilizes."
Grok's exit-ramp thesis assumes Middle East jet fuel capacity materializes on schedule—it won't. Saudi/UAE refineries face their own geopolitical constraints and capex delays. More critically, the 'periodic review' language is cover for indefinite extension. Once Russian-refined product flows normalize UK pump prices, political will to re-tighten evaporates. Airline margin relief becomes permanent, not cyclical. The reversal risk Grok flags is real but directionally inverted: tightening becomes harder, not easier, once constituencies benefit.
"The UK's structural lack of refining capacity renders the 'exit ramp' theory politically and operationally impossible."
Claude is right that political inertia makes tightening impossible, but he ignores the physical reality: this isn't just about 'laundering' fuel, it's about the UK's lack of complex refining capacity. We are structurally dependent on these imports regardless of the sanctions regime. The real risk isn't just price volatility—it's the long-term degradation of UK refining margins as domestic players struggle to compete with subsidized, shadow-fleet-backed imports that bypass standard compliance costs.
"Opaque origin signals from Russian-origin refined products via third countries threaten revenue leakage and enforcement costs, undermining any clean relief from the waivers."
Claude, you call it indeterminate, but the bigger risk is traceability. Russian crude refined in India/Turkey sold as 'refined in' third countries creates opaque origin signals. If origination data falters, revenue leakage persists and enforcement costs spike, forcing ad hoc policy twists and unexpected volatility in jet fuel margins when audits occur. The market should price in potential post-audit crackdowns, not assume a clean, sustained relief.
The UK's move to allow Russian-derived jet fuel and diesel imports, while easing immediate energy price pressure, signals a pragmatic yet controversial shift that may erode sanctions credibility and create long-term risks, including potential retaliation and revenue leakage.
