The Global Fuel Crisis Could Last For Years — And Peace May Not Fix It
Oil Prices Are Only Half The Story — The Real Fuel Crisis Is Getting Worse
Why The Global Fuel Crisis Could Outlive The War That Started It
The world’s fuel crisis is beginning to look much harder to solve than a simple spike in the price of crude oil.
Nearly six months of disruption around Iran and the Strait of Hormuz have already distorted global energy flows. But the pressure is now spreading deeper into the system. Refineries have been damaged or forced offline, Russian processing has been disrupted by Ukrainian attacks, fuel inventories have been drained and the supply of diesel, petrol and jet fuel has tightened even as some crude production has begun to recover.
That creates an uncomfortable possibility: even if the geopolitical crisis suddenly eases, consumers may not get cheap fuel back nearly as quickly.
The global economy is no longer dealing with just an oil shortage. It is increasingly dealing with a refining shortage.
The Oil Crisis Has Become A Fuel Crisis
Oil and fuel are not the same thing.
Crude oil has to be transported to a refinery and processed into products such as petrol, diesel, jet fuel and heating oil before most consumers can use it. That refining stage has become one of the weakest points in the global energy system.
The International Energy Agency said global refinery crude throughput reached 80.9 million barrels per day in July, but remained almost 5 million barrels per day lower than a year earlier. It also said tighter supplies of light and middle distillates had pushed refining margins in the Atlantic Basin to record levels.
That gap matters because there is no easy substitute for a refinery.
More crude arriving at ports does not automatically create more diesel. An oil producer can restart wells relatively quickly if infrastructure remains intact. A damaged refinery may require replacement equipment, specialist engineering work, safety inspections and months of reconstruction before it operates normally again.
This is why crude prices can fall while the price of finished fuels remains painfully high.
Reuters reported this week that European diesel prices had risen by more than 70% during the current crisis while US gasoline prices were around 60% higher than in February. The same analysis pointed to major refinery outages in the Gulf and a roughly 30% reduction in Russian refinery throughput.
The problem is no longer confined to the price of a barrel.
It has moved into the machinery that turns that barrel into something the world can actually use.
Why The Strait Of Hormuz Still Matters
The Strait of Hormuz remains one of the most important pieces of infrastructure in the global economy.
Before the latest conflict, roughly one-fifth of global oil and LNG trade passed through the narrow waterway. Shipping activity has since fallen dramatically during periods of renewed confrontation. Recent tracking data showed only a handful of commodity vessels moving through during one weekend, compared with more than 130 daily ship transits before the war began.
Washington and Tehran have also given conflicting accounts of whether the waterway is effectively open.
President Donald Trump has said the strait is open, while Iranian officials have continued to describe it as closed or controlled by Tehran. Whatever terminology is used, actual tanker activity remains well below normal levels, which is what ultimately matters to traders, refiners and fuel buyers.
Oil markets reacted again on August 20.
Brent crude climbed above $93 a barrel, reaching its highest level in more than three weeks, as investors priced in continuing Middle East supply risk and the lack of a diplomatic breakthrough.
The Strait therefore remains the immediate pressure point.
But reopening it would only solve part of the problem.
Peace Would Help — But It Would Not Repair Refineries Overnight
This is the central contradiction in the crisis.
A ceasefire could change oil prices within hours. It could lower shipping insurance costs, encourage tankers back into the Gulf and allow producers to increase exports.
It cannot instantly rebuild a refinery.
More than 20% of the Middle East’s roughly 9.6 million barrels per day of refining capacity has been offline during the crisis, according to Reuters analysis. At the same time, attacks have cut Russian refining capacity and disrupted another major source of global diesel supply.
Europe is particularly exposed because it relies heavily on imported middle distillates.
The IEA said diesel exports from Russia, the Middle East and Asia were around 1.3 million barrels per day lower year-on-year in July, equivalent to roughly 20% of global seaborne diesel trade. Jet fuel exports from those regions were down about 670,000 barrels per day, or around 34% of global trade.
Those are not small disturbances at the edge of the market.
They are losses large enough to influence freight costs, aviation, agriculture and the price of transporting almost everything consumers buy.
Diesel May Be The Most Dangerous Part Of The Story
Petrol receives most of the political attention because drivers see its price displayed publicly every day.
Diesel may matter more to the wider economy.
Trucks run on it. Agricultural machinery relies on it. Construction equipment consumes it. Ships and industrial users are heavily exposed to middle-distillate markets.
When diesel becomes scarce, the cost does not stop at the filling station.
It moves into supermarket shelves, construction projects, food production and supply chains.
The strain is already visible in market pricing. The US diesel crack spread — effectively the margin between crude and diesel — exceeded $100 per barrel for the first time this week. US distillate inventories were also reported at their lowest August level since 1996 despite strong refinery utilisation.
That is an extraordinary signal.
It means refiners are being rewarded heavily for every extra barrel of diesel they can produce because the market desperately wants the finished product.
The World Has Already Burned Through Part Of Its Safety Cushion
Inventories are supposed to absorb temporary disruption.
But temporary disruption becomes more dangerous when it lasts for months.
The IEA estimates that observed global oil stocks fell by 69 million barrels in July alone. Since the war began, inventories have fallen by roughly 410 million barrels, averaging a draw of around 2.7 million barrels per day.
Strategic reserves and commercial stockpiles can soften an emergency.
They cannot permanently replace functioning production, refining and shipping routes.
The longer governments use inventories to cover missing supply, the less protection remains against the next shock.
And there are several possible next shocks.
Another major tanker incident could discourage shipping. Further attacks on Russian refineries could remove more diesel. Renewed fighting in the Gulf could damage additional infrastructure. Sanctions could redirect Chinese and Indian crude purchases again.
This is what turns an expensive market into a fragile one.
China And India Are Being Pulled Into The Shock
The crisis is also rearranging global oil trade.
China has increased purchases of Russian crude as its access to Iranian barrels has been constrained, according to current shipping estimates. Chinese imports of seaborne Russian crude are expected to reach around 1.25 million barrels per day in August.
That has consequences for India.
India had become one of the biggest buyers of discounted Russian crude following the invasion of Ukraine, refining some of those barrels domestically and exporting fuel back into international markets.
But Indian imports of Russian crude have fallen from more than 2.7 million barrels per day in June and July to an estimated 1.87 million barrels per day in August as Chinese demand absorbs more available supply.
If Indian refiners cannot secure enough crude, Asia loses another important source of finished fuel.
China is trying to ease some of that pressure. Its refined-fuel exports rose in July after Beijing loosened restrictions, with diesel exports jumping sharply from June. Even so, total refined-product exports remained below year-earlier levels.
The fuel crisis is therefore becoming a giant global reallocation exercise.
Every barrel redirected towards one country risks leaving another refinery short.
Why This Could Take Years Rather Than Months
There is a crucial distinction between saying the current emergency will last for years and saying the damage it has exposed could influence fuel markets for years.
Nobody can reliably predict how long the Iran conflict will last.
The stronger case is structural.
New refineries are huge industrial projects. They require enormous capital expenditure, environmental approval, engineering expertise and years of construction. Existing plants can increase utilisation, but many are already running hard.
Reuters analysis notes that new refining capacity is being added globally, but not fast enough to guarantee an immediate replacement for disrupted capacity. Building significant new capacity takes years.
There is also an investment dilemma.
Governments are simultaneously pushing towards electrification and lower fossil-fuel consumption. Oil companies therefore face a difficult decision: spend billions on refining assets that may be badly needed during the late 2020s but could face weaker demand later as electric vehicles and cleaner technologies spread.
That creates a strange vulnerability.
The world may be moving away from oil over the long term while still being dangerously dependent on a limited number of refineries in the short term.
Inflation Could Be The Political Consequence
Fuel inflation rarely remains fuel inflation.
Higher petrol prices hit households directly. Higher diesel prices raise freight and agricultural costs. Higher jet-fuel prices increase airline costs. Higher energy costs can filter into manufacturing and services.
Reuters analysis estimated that energy pressure contributed to US consumer inflation reaching 3.4% in July and eurozone inflation reaching 2.9%.
That creates a problem for central banks.
If inflation remains elevated because of imported energy costs, interest rates may need to remain higher than they otherwise would.
Governments then face the worst kind of economic squeeze: voters angry about fuel prices, businesses facing higher costs and borrowers still paying expensive interest rates.
The energy shock therefore has the potential to outlive the battlefield economically even if it does not outlive it militarily.
Could Oil Still Fall Sharply?
Yes.
That is the strongest argument against assuming permanently high prices.
A durable peace agreement, reopening of the Strait of Hormuz, restoration of Gulf production and strong growth in supply from the Americas could dramatically reduce the crude oil risk premium.
The IEA currently expects global oil supply to rebound strongly in 2027 after declining in 2026. It forecasts a return to oil-demand growth next year as well.
China is already increasing fuel exports. US refiners are running hard. High refining margins create a powerful financial incentive to maximise production.
So this is not a prediction that petrol or diesel must rise indefinitely.
It is a warning that falling crude prices would no longer guarantee falling fuel prices at the same speed.
That distinction could define the next phase of the crisis.
What Happens Next
Three things now matter more than almost anything else.
The first is actual shipping traffic through the Strait of Hormuz, rather than political claims about whether it is technically open.
The second is refinery recovery across the Gulf and Russia.
The third is global inventories. If stocks continue falling while refining remains constrained, the world will have less protection against another disruption.
The IEA currently expects some improvement in the broader oil balance towards the end of 2026. But it also says risks remain substantial, with available inventory buffers rapidly being depleted.
That leaves the world in an unusual position.
The crude shortage could ease before the fuel shortage does.
And if that happens, the end of the war may not mark the end of the energy crisis. It may simply reveal how much of the damage was built into the system underneath it.
