Europe’s Diesel Shock: Why the World Is Running Short of Fuel, Not Oil

The problem is no longer simply how much oil the world can produce. It is whether that oil can be processed into the fuels that keep economies moving, and then delivered to the places that need them.

That distinction is becoming exceptionally expensive. Brent crude is currently trading near $106 a barrel, while in the United States, diesel has climbed to about $6.28 a gallon.

For governments accustomed to treating oil prices as the principal measure of energy security, the gap between crude benchmarks and the cost of finished fuels is becoming a political and economic problem in its own right.

The missing link between crude and the pump

Oil production and fuel availability are not interchangeable. Crude must pass through refineries before it becomes diesel, petrol or jet fuel. Those facilities require functioning infrastructure, access to feedstock and reliable transport links. When any of these fail, additional crude supplies cannot necessarily compensate for the missing output.

The current squeeze has developed across several parts of that system. Military strikes have damaged refining capacity in Russia and the Middle East, while insecurity around key maritime corridors has complicated the movement of energy supplies. China, meanwhile, has restricted refined fuel exports to protect its domestic market, removing volumes that would otherwise help balance international demand.

The result is a market in which finished products are becoming harder to obtain even when crude remains available for purchase.

Refinery capacity losses in Russia alone have increased by 3mn barrels a day year on year, according to the figures in the newsroom briefing. China's decision to halt the majority of its October exports of petrol, diesel and jet fuel has added another constraint. Stocks in the Amsterdam-Rotterdam-Antwerp storage hub are depleted, while US Midwest petrol inventories have fallen to 204mn barrels, their lowest level since November 2014.

These pressures reinforce one another. Damaged refineries produce less. Export restrictions prevent available supplies from reaching foreign buyers. Lower inventories leave importers with less room to manage delays or sudden increases in demand.

The market has lost some of its ability to smooth out regional disruptions.

Why another barrel of oil is not enough

The distinction between crude and refined products also helps explain why conventional responses to rising fuel prices have struggled to deliver relief.

A government can seek additional crude supplies, release reserves or negotiate with producing countries. None of those measures automatically restores damaged refining capacity or guarantees that diesel will arrive at the right port. Where the shortage concerns a particular fuel, the availability of additional raw material may offer only limited relief.

Finished transport fuels are trading at the equivalent of roughly $150-$190 a barrel, according to the briefing. The premium reflects the difficulty of obtaining products that can be used immediately, rather than simply the cost of the oil from which they are made.

For businesses, that distinction runs through the entire economy. Diesel powers freight transport and agricultural machinery; jet fuel supports aviation; and higher transport costs feed into the prices of goods far beyond the energy sector. Manufacturers and distributors must absorb the additional expense, pass it on to customers, or reduce their margins.

The consequences are particularly difficult for economies dependent on imported refined fuels. They may be able to buy crude on international markets, but that does not guarantee access to the finished products their transport networks and industries require.

Nor can emergency measures easily correct the imbalance. Latvia has temporarily reduced fuel excise taxes by eight cents a litre, providing some relief to motorists. Yet a tax reduction changes the price paid at the pump, not the volume of diesel available to the market. It also leaves governments bearing the cost of intervention while the underlying supply constraints persist.

When energy infrastructure becomes a battlefield

The attack on Dhahran illustrates another dimension of the crisis: the growing exposure of energy systems to military operations designed to impose costs well beyond the immediate target.

The Houthis, backed by Iran, have intensified attacks against Saudi petroleum infrastructure and airports. A previous assault on Riyadh's international airport left 13 people dead and more than 300 wounded, according to the briefing. Saudi Arabia has responded with air raids against Houthi-held targets in Yemen, including fuel terminals and oil storage facilities.

Such exchanges create risks that extend beyond the sites directly hit. Energy markets depend on the assumption that production facilities, processing plants and shipping routes will remain sufficiently secure to maintain a predictable flow of supplies. Missile and drone attacks challenge that assumption, forcing operators and governments to consider not only the physical damage caused but also the possibility of further disruption.

A strike does not need to destroy a refinery to affect the wider market. The prospect of repeated attacks can complicate operations, increase security requirements and make transport through exposed corridors more difficult. When inventories are already low, even a temporary interruption can have a disproportionate effect.

The vulnerability is especially acute around maritime chokepoints. Insecurity in the Strait of Hormuz and the Red Sea has disrupted tanker routes, raised insurance and freight costs, and lengthened delivery times. These are not separate from the refining problem. They determine whether available fuel can reach buyers quickly enough to prevent local shortages.

The military and economic consequences are therefore increasingly intertwined. Infrastructure that once appeared to be a technical component of energy production has become a strategic target whose disruption can affect inflation, trade and political stability far from the battlefield.

Asia's retreat from the export market

China's restrictions on refined fuel exports expose another weakness in the international system: the assumption that major producers will continue supplying foreign markets when domestic priorities become more pressing.

In normal conditions, exports help move surplus production towards regions experiencing tighter supply. When a large economy restricts those flows, importers must compete for fewer available cargoes. Alternative suppliers may benefit from higher margins, but their additional output cannot necessarily replace the missing volumes quickly enough.

The effects extend beyond Europe and the United States. Developing economies and island markets often have fewer options for sourcing fuel and depend heavily on maritime deliveries. They are particularly exposed when shipping delays coincide with limited inventories and sudden increases in demand.

Bali offered a small but revealing example on 12 and 13 October. Filling stations in Denpasar, Badung and Kuta experienced severe shortages and queues lasting several hours. Indonesia's state-owned energy company Pertamina attributed the disruption to a technical delay in tanker offloading and panic buying of subsidised Pertalite petrol, daily consumption of which rose to 2,200 kilolitres.

The Indonesian authorities dispatched emergency shipments totalling 26,200 kilolitres, with tankers arriving on 12, 14 and 16 October. Governor Wayan Koster urged residents to remain calm.

Bali's difficulties do not, by themselves, demonstrate a national shortage or a direct consequence of the global diesel deficit. The immediate trigger was a local distribution problem compounded by consumer behaviour. But the episode illustrates how quickly a disruption can reach motorists when supply depends on maritime deliveries and retail inventories offer little protection against delays.

In an import-dependent tourist economy, queues at filling stations are not merely an inconvenience. They threaten the movement of workers, visitors and goods on which local businesses rely. Emergency shipments can restore supply, but the need to arrange them exposes the limits of a system with little tolerance for interruption.

The new politics of fuel prices

For Western governments, the crisis presents a different problem. Europe is confronting high prices rather than the widespread physical shortages seen in some more exposed markets. The political effects, however, may prove just as persistent.

In the United States, Donald Trump has accused the Houthis of deliberately raising crude prices ahead of the 3 November congressional midterm elections, alleging coordination with Iran to put pressure on American consumers. The briefing provides no evidence establishing such a pre-election conspiracy.

The underlying economic pressure is less ambiguous. US diesel prices have risen sharply, and attempts by Trump to ease costs through an arrangement with Russia involving the restoration of diesel shipments and temporary sanctions relief faltered as diesel futures rose 4.5 per cent on 13 October.

The episode illustrates the limitations of treating fuel inflation as a problem that can be solved through a single diplomatic agreement. Additional Russian shipments might help if they materialise in sufficient quantities, but they cannot by themselves reverse the wider loss of refining capacity, replenish depleted inventories across multiple markets or remove maritime bottlenecks.

The IEA's warning that the diesel deficit could continue into 2027 makes the political challenge harder. Temporary tax cuts and emergency supply arrangements can soften the immediate impact, but prolonged high fuel costs would continue to work their way through freight, food production and consumer prices.

Governments may also find that energy security increasingly requires cooperation on infrastructure protection, not just negotiations over supply. Ukraine and Saudi Arabia formalised a defence co-operation agreement in March under a framework known as the Drone Deal, covering electronic warfare, counter-drone systems and anti-drone technology sharing.

The significance of that relationship is clear in principle: Ukraine has experience defending against Iranian-supplied loitering munitions, while Saudi Arabia has exposed energy infrastructure that must be protected against aerial threats. Regional security and energy resilience are becoming closely connected.

There is, however, no direct evidence linking a Ukrainian Il-76MD transport flight from Lviv to Saudi Arabia's Sharurah airport, near the Yemeni border, to a transfer of military hardware. The aircraft's cargo remains undisclosed. The flight cannot establish what assistance, if any, was delivered.

The broader shift is that protecting energy supplies increasingly involves technologies and expertise developed on active battlefields. For states whose economies depend on uninterrupted fuel production and transport, defence co-operation is becoming part of the infrastructure investment equation.

A longer squeeze on industrial economies

The danger is not necessarily a sudden exhaustion of the world's oil reserves. It is a prolonged shortage of the particular fuels required to keep industrial economies functioning.

Refineries cannot be rebuilt or repaired instantly. Shipping routes cannot be made secure by price controls. Export restrictions can redirect scarcity rather than eliminate it, while low inventories leave importers vulnerable to the next disruption.

The burden falls unevenly. Refiners operating outside conflict zones with secure access to transport may capture unusually high margins. Import-dependent economies, meanwhile, face higher bills without any guarantee of improved supply. For businesses that cannot easily reduce fuel consumption, the additional cost becomes a persistent pressure on profitability and investment.

The central difficulty is that these vulnerabilities are no longer confined to a single region. Damage to Russian refining capacity, attacks on Saudi infrastructure, Chinese export restrictions and disruptions to maritime transport are occurring within the same interconnected market. Each compounds the others, leaving fewer alternative sources and less time to respond when something goes wrong.
