Diesel prices are proving slower to retreat than crude, even as gasoline costs have eased from their spring peak. The IEA’s latest figures point to a split recovery in fuel markets: weaker crude prices haven’t produced equal relief across products, and distillate supply constraints and local pricing factors are keeping pressure on some pump prices.
Diesel holds above its prewar level
The IEA’s monthly end-use price tracker, updated Aug. 7 with data through July, puts the average automotive diesel price across tracked countries at about $1.94 per liter. That’s roughly 14% above February, before the war began, and higher than June despite crude prices falling through much of the summer. The average reflects prices paid by end users across different national markets, where taxes, currencies and retail pricing structures can all affect the result.
Gasoline has followed a softer path. Its average price peaked at about $1.99 per liter in May, then eased to $1.90 in July, little changed from the prior month. Diesel’s relative resilience is the clearest sign that falling crude hasn’t yet translated into broad relief at the pump. Crude is a major input, but the price of a finished fuel also depends on refining capacity, product inventories and the cost of moving it to customers.
This is more significant than it looks: a retreat in the headline oil benchmark can coexist with persistent pressure on the fuel used by freight, industry and other commercial activity. The figures don’t establish that every diesel market is tightening, but they do show that crude’s decline hasn’t erased the earlier rise in the tracked average.
Crude has retreated, but Gulf risks remain
After U.S. and Israeli strikes on Iran on Feb. 28 killed the country’s supreme leader and triggered war, Brent climbed from around $72 a barrel to nearly $120 within weeks. The surge was the benchmark’s sharpest one-month rise since the 1990 Gulf War. Tanker traffic through the Strait of Hormuz, which carries roughly a fifth of global oil, nearly stopped as insurers withdrew coverage and Iran threatened ships attempting the route.
That episode showed how quickly a threat to a major shipping corridor can feed into oil pricing. Even where supply isn’t physically lost, uncertainty about whether cargoes can move, and what it will cost to insure them, can raise the risk premium buyers attach to future deliveries. Those costs can also take time to work through supply chains after crude prices turn lower.
Brent has since pulled back, trading near $88 a barrel this week, according to market prices. That remains more than 30% above its level a year ago. J.P. Morgan expects Brent to average $86 in the third quarter and move toward $78 by year-end, on the assumption that the conflict doesn’t intensify again. That forecast is conditional: a renewed escalation or fresh disruption to shipping would challenge the lower-price scenario.
Iran and Oman are still negotiating terms for a full reopening of Hormuz, leaving the market exposed to shifts in the talks. A June 17 memorandum of understanding between the U.S. and Iran fell apart within days over shipping-route disputes. Tanker attacks and the attack on Saudi Arabia’s Jazan refinery continued to surface through early August. The combination leaves traders weighing the price decline against unresolved operational risks. A lower benchmark, but not a settled market.
Local factors widen the price gap
Country-level data show that crude is only part of the pump-price story. Germany’s diesel and gasoline prices each rose by more than 10% in July. The increase coincided with the expiration on June 30 of Berlin’s temporary fuel-tax discount, introduced in May at nearly 17 cents per liter to cushion the impact of the war. When a tax reduction ends, retail prices can rise even if the underlying fuel market is easing, which complicates comparisons between countries and across months.
Prices fell in the U.K., Ireland, Sweden and Cyprus over the same period. Taxes and exchange-rate moves can therefore alter what drivers pay even when global oil prices are moving in the same direction. A shared benchmark doesn’t produce a uniform retail response: currency movements change the local cost of imported fuel, while taxes and distribution costs shape the final price.
If you're working in this space, the distinction matters when interpreting a national price move. A rise at the pump may reflect a change in policy or currency as much as a change in crude; a fall may also mask tightness in a particular product market.
Distillate supply adds pressure
Diesel also faces a tighter supply backdrop. Ukraine carried out at least 30 drone strikes on Russian refineries in July, pushing Russian crude-processing rates to a 24-year low and prompting fuel rationing in about 90% of the country’s regions. The disruption has tightened supplies of diesel and other middle distillates, while gasoline has held up better.
Refineries produce multiple fuels from crude, so disruption to processing can affect the availability of several products. The balance varies by refinery and market, however; the reported pressure on diesel and other middle distillates doesn’t mean gasoline is unaffected everywhere. It does help explain why crude benchmarks alone may give an incomplete picture of near-term pump prices.
That said, the available figures don’t quantify how much of diesel’s price resilience comes from refinery disruption, shipping risk or local costs. They point to several pressures operating at once, rather than a single cause that can be isolated from this data.
What could shape the next move
In the U.S., IEA figures put July diesel at about $4.96 per gallon and gasoline at $3.93, compared with $3.78 and $3.12 a year earlier. The year-on-year comparison underscores that both fuels remain more expensive than a year ago, even after crude retreated from its wartime peak. Diesel’s larger increase in these figures is consistent with the broader divergence between the two fuels, though the data alone don’t identify a single driver.
Further price declines will depend less on OPEC+ output alone than on whether Gulf shipping conditions stabilize and distillate supply recovers. Crude supply decisions matter, but so do refinery operations and the movement of finished fuel to market. For drivers and businesses that depend on diesel, the key signal will be whether product prices begin to ease alongside crude. Here's the thing: until that gap narrows, a softer oil benchmark offers only partial relief.
