IEA warns diesel prices in Europe could rise as global crunch lasts into 2027

The IEA expects European wholesale diesel prices to rise because fuel markets remain tight. Global oil output reached 102.3 million barrels a day in September, but demand was about 103.5 million. Diesel is under additional pressure because Middle Eastern fuel exports are below half their pre-war levels, while Russian refineries have been hit by Ukrainian drones.

Shipping is another important mechanism. Tensions around the Gulf have spread from crude tankers to other tanker categories. Higher freight costs raise the price of diesel delivered to Europe, one of the world's major gasoil-importing markets. The IEA therefore warns that prices could rise again in the coming weeks.

Diesel benchmarks have fallen from September records above $200 a barrel, but remain nearly twice crude prices and pre-crisis levels. The IEA expects lost diesel stocks will not be replenished beyond normal seasonal changes before the second half of 2027. Continued attacks could create further turmoil.

Diesel is a liquid fuel made by refining crude oil. It is commonly used in trucks, buses, ships, farm equipment, generators, and some cars. Crude oil is the unprocessed mixture pumped from underground or recovered at sea. It is not the same finished product as diesel and cannot simply be used in a diesel engine without refining.

Refineries heat and separate crude into different products, including diesel, gasoline, and other fuels. This distinction matters in the article because crude output can recover while diesel supplies remain tight. Gulf crude exports rose sharply, but Middle Eastern fuel exports stayed below half their pre-war levels, and Russian refineries faced drone attacks.

The article reports that diesel benchmarks remain nearly double crude oil prices and their pre-crisis levels. That comparison shows how a shortage of refined fuel can create a much sharper market squeeze than the broader crude supply picture alone suggests.

The reported shortfall is about 1.2 million barrels a day. The IEA estimated September global output at 102.3 million barrels a day, compared with demand of roughly 103.5 million. Subtracting production from consumption gives the gap. Supply therefore remains below demand despite a large monthly recovery.

Output rose by 2.5 million barrels a day in September. The increase was led by Saudi Arabia and a jump in Gulf crude exports to more than three-quarters of pre-war levels. Even so, the recovery did not fully close the gap. Ongoing attacks, restricted shipping, and refinery damage continue to affect usable fuel supplies.

This imbalance helps explain why markets remain sensitive to disruption. The article says diesel markets could stay tight well into 2027, and the IEA warns that oil markets may face more turmoil before any eventual surplus emerges in 2027. The daily gap is small, but its effects can be substantial.

The Strait of Hormuz is a crucial route for about a fifth of the world's oil. When Iran restricts passage or attacks ships, exporters, traders, and buyers face delays and greater danger. That risk affects more than crude cargoes. It can disrupt fuel shipments and increase the cost of moving energy through the region.

The article gives several examples. UKMTO reported projectiles hitting a tanker and a container ship. Iran's Revolutionary Guards said a container ship sank after hitting a naval mine and catching fire. As tensions spread to other tanker categories, freight costs rise for vessels carrying diesel. Europe, Africa, and Latin America are major gasoil-importing markets exposed to those costs.

The result is a wider price effect far beyond the Gulf. Even recovering Gulf crude output has not resolved the fuel squeeze. The IEA says delivered diesel prices in Europe could rise again in the coming weeks, while renewed attacks leave the supply recovery fragile.

Diesel prices come under pressure when fewer finished fuel barrels reach the market. The article says Middle Eastern fuel exports are below half their pre-war levels. It also says Russian refineries have been hit by Ukrainian drones. Together, those disruptions reduce available diesel even while global demand remains substantial.

The mechanism is straightforward. Buyers compete for fewer cargoes, and shipping companies face greater risks around the Gulf. The IEA says crude freight-market tensions have spread to other tanker categories. Higher freight costs then increase the delivered price of diesel in Europe, Africa, and Latin America, all described as important gasoil-importing markets.

Diesel prices have retreated from September records above $200 a barrel, but remain nearly double crude prices and pre-crisis levels. The IEA expects lost diesel stocks will not be replenished beyond normal seasonal changes before the second half of 2027, keeping prices vulnerable to further disruption.

Emergency stock releases can temporarily add diesel to the market, but they may not solve a prolonged shortage. The G7 pledged on 2 October to release up to 100 million barrels through the IEA, with diesel first. However, an internal document reported by Euronews said the barrels would cover amounts still owed under March's 400 million-barrel pledge, rather than increase that commitment.

Alternative shipping routes may help some cargoes avoid danger, but the article does not say they can replace Hormuz volumes or prevent shortages. Attacks have already raised concern across tanker markets. As tensions spread beyond crude freight, higher shipping costs can lift delivered diesel prices in Europe even when cargoes continue moving.

The IEA expects diesel stocks lost during the crisis will not be replenished beyond normal seasonal changes before the second half of 2027. Stock releases and rerouting may cushion disruption, but the article indicates that lasting relief depends on supply recovery and reduced conflict. Until then, markets remain fragile.

Crude oil is the raw material, while diesel is a finished product that must be produced, stored, and transported. A disruption can therefore affect diesel at several stages. If refining capacity is limited or refineries are damaged, less crude becomes available diesel. If inventories are already low, buyers have less protection, so a small supply gap can cause a large price response.

The article shows these pressures together. Russian refineries have been hit by Ukrainian drones, Middle Eastern fuel exports are below half their pre-war levels, and tanker freight costs are rising. Diesel benchmarks have retreated from September records above $200 a barrel but remain nearly double crude prices. That gap reflects pressure specific to the refined-fuel market.

Seasonal demand can further affect how quickly stocks are rebuilt. The IEA says lost diesel stocks are unlikely to be replenished beyond normal seasonal changes before the second half of 2027. Thus, crude prices may move modestly while diesel rises sharply when refining, inventories, freight, and demand tighten simultaneously.
