Britain stands alone at the sharp end of a fuel crisis few saw coming this fast. The prolonged shutdown of the Strait of Hormuz has tightened jet fuel markets across Europe. Yet analysts at Goldman Sachs single out the UK.
Commercial inventories here could drop to critically low levels within weeks. Rationing measures may follow. The warning, contained in a client note circulated this week, paints a picture of structural weakness that leaves British airlines, freight operators and the small businesses that rely on them exposed like nowhere else on the continent.
The investment bank points to three compounding problems. Depleted stockpiles. Heavy dependence on imports. And a domestic refining sector stripped back over years of closures and sales. “The UK is the largest net importer of jet fuel in Europe, and it holds no strategic reserves, leaving commercial inventories as the primary buffer,” Goldman Sachs analysts wrote. “As a result, inventories in some countries, especially the UK, could fall to critically low levels, increasing the likelihood of rationing measures.” (The Independent).
Those words carry weight. Jet fuel prices have doubled since late February when the conflict escalated and tanker traffic through the strait slowed to a trickle. The Gulf region supplies roughly one fifth of internationally traded jet fuel. Europe now scrambles for replacements from the United States, Asia and West Africa. But replacement takes time. Tankers reroute. Refineries adjust yields. And buffers disappear.
UK businesses feel the pinch first. Soaring ticket prices. Consolidated routes. Freight rates climbing. Thousands of SMEs depend on air links for time-sensitive exports, components and client meetings. Many use the belly cargo holds of passenger flights. When those flights vanish or become pricier, orders slip and margins shrink. One industry source told BM Magazine that mid-to-late June marks the point where disruptions could bite hardest, right as summer peaks.
Refining capacity tells part of the story. Scotland’s only oil refinery at Grangemouth closed in April 2025. Questions linger over the future of the Prax Lindsey site in North Lincolnshire, though new owner Phillips 66 promises it will strengthen supply security. The government has urged the four remaining refineries — Fawley, Humber, Pembroke and Stanlow — to maximize jet fuel output. Still, Britain imports more than 60 percent of its needs. No strategic stockpile exists to cushion shocks. (City A.M.).
Airlines already adjust. Globally, carriers removed nearly two million seats from May schedules in recent weeks. Some 120 UK flights canceled this month alone. Prices for fuel now eat up to a quarter of operating costs at many carriers. British Airways parent IAG says it will pass higher costs to customers despite hedging. International peers face even bigger hits. Air France anticipates an extra $2.4 billion annual fuel bill. American Airlines expects $4 billion more. Ryanair chief Michael O’Leary observed that European rivals hunt flights to cut, acting “desperately.”
But industry leaders push back on immediate panic. Tim Alderslade, chief executive of Airlines UK, stated clearly: “No flights are being cancelled due to fuel shortages. UK airlines are planning to operate their full schedules this summer, including the May half-term.” Mark Tanzer, chief executive of ABTA, echoed the line. “The government and airlines are clear that there isn’t a problem with fuel supply. If you have a holiday booked in for the coming months – including the May half term – we expect it to go ahead as planned.” (BBC).
The Department for Transport adds its voice. Airlines buy fuel well in advance. Airports hold reserves. Contingency plans allow carriers to consolidate flights, protect slots and avoid penalties for cancellations. Officials insist most summer travel will look much like last year. Passengers facing disruption retain rights to refunds or re-routing. No one should cancel plans yet.
Still, the Goldman note highlights deeper frailty. A recent report from the Tony Blair Institute for Global Change argues Europe’s climate-driven energy policies have raised power costs two to three times higher than global competitors while increasing reliance on imports. That vulnerability now shows in aviation fuel. The European Commission prepares formal guidance for airlines. Spokeswoman Anna-Kaisa Itkonen captured the uncertainty. “I don’t think anyone knows how long this situation will last, so the best we can do and the most effective thing we can do and that we are doing is to prepare for all eventualities.”
Prime Minister Sir Keir Starmer offered blunt advice. Holidaymakers may need to reconsider destinations. Staycations or closer European spots could replace long-haul sun. Transport Secretary Heidi Alexander is expected to warn explicitly that cancellations could affect summer plans. Behind the scenes, ministers explore imports from the US and West Africa, including Nigerian sources, to bridge the gap.
Market signals tell their own tale. Jet fuel stocks in the Amsterdam-Rotterdam-Antwerp region provide one indicator, but UK visibility remains limited because of its specific sourcing patterns. Earlier warnings from the International Energy Agency in April flagged possible physical shortages across Europe by June if only half the lost Middle East supply could be replaced. Recent Reuters reporting noted uneven stocks. Spain, a net exporter with eight refineries, sits in better shape. Britain does not. (Reuters).
Longer term questions loom. Decades of refinery rationalization left the UK with less domestic production precisely as geopolitical risks returned. Climate targets pushed investment elsewhere. Now the bill arrives at peak travel season. Airlines lobby to relax environmental and noise rules to ease cost pressure. Some carriers already trim perks and raise fares. Business travelers face pricier tickets and fewer options. Freight costs climb for exporters of perishable goods or high-value items.
Yet the government and industry maintain measured calm. Current supply holds. Advance purchases provide runway. International partners coordinate. The risk of formal rationing remains a contingency, not a certainty. Even so, Goldman Sachs’ assessment forces attention on preparedness. Inventories cannot fall much further without choices being made. Who flies. Who pays more. Whose cargo moves first.
That tension defines the moment. Short-term reassurance meets long-term exposure. British businesses cannot easily switch to sea freight for time-sensitive needs. Families hesitate over holiday bookings. Airlines juggle schedules while watching fuel tenders. And policymakers weigh how much intervention the market truly needs.
The Strait may reopen. Tankers may resume. Prices may ease. But the underlying weaknesses Goldman Sachs highlighted will not vanish overnight. Refining capacity, strategic reserves and import dependence remain policy choices with immediate commercial consequences. For an island nation built on global connections, those choices now carry fresh urgency.
