The Global Diesel Market Is Breaking Down. Two Wars Are Driving the Squeeze

Diesel powers much of the physical economy, from trucks and tractors to ships moving goods around the world. Wars have disrupted supplies from two major exporting regions, pushing prices to records and prompting the Group of Seven to tap emergency reserves on Oct. 2.
The move puts more fuel into the market while removing another threat hanging over global supply. The US also backed away from restricting diesel exports, which could have cut shipments to regions that rely heavily on American refiners.
What the G7 actually agreed
G7 countries agreed to release 100M barrels of diesel and crude from emergency stockpiles following pressure from President Donald Trump. The release will run over four months, although the statement did not specify how much each country would contribute.
A substantial diesel release will be frontloaded into the first 20 days, according to G7 leaders. Energy Aspects analysts described the agreement as more of a political statement than a binding commitment, aimed partly at heading off a US export ban.
Oil prices moved little after the announcement, with Brent crude futures slipping 6 cents to $102.25 per barrel. US West Texas Intermediate crude fell $1.76 to settle at $91.11.
Why the ban mattered more than the barrels
A US ban on diesel exports would have removed supply from countries that depend heavily on American refiners. The industry also warned that restricting exports could force domestic plants to cut output rather than simply redirect every barrel into the US market.
G7 members instead pledged to refrain from export restrictions on energy products between themselves, while Trump confirmed the US would not impose a ban.
The decision matters well beyond the US, with Latin America sourcing about 90% of its diesel imports from American suppliers. Europe has also become increasingly reliant on those barrels, with the US supplying nearly 40% of its diesel imports last month.
The shortage itself is untouched
Before the Iran war, the Middle East accounted for 19% of global diesel exports, according to commodities tracker Kpler. Persian Gulf shipments had fallen to roughly a quarter of their prewar level by August.
Russian supply has been squeezed at the same time, with diesel exports falling to about 20% of their May level by August following Ukrainian strikes on refineries. Russia has extended its own export ban through the end of October.
The resulting squeeze has pushed US diesel to record levels, reaching $6.52 a gallon last week before easing to $6.39. That leaves prices roughly 70% higher than when the Iran war began, while the EU average reached a record $9.63 a gallon this week.
Refiners also face limits on how much diesel they can produce from each barrel of oil. A 42-gallon barrel of crude yields roughly 11 to 13 gallons of diesel in the US, according to the Energy Information Administration.
Europe had 36M tons of diesel in reserve at the end of June, equal to roughly two months of consumption. Fuel released from those stockpiles will eventually need to be replenished, shifting some of the buying rather than eliminating it.
How investors are positioning
Energy stocks initially fell after the announcement before recovering some of those losses. ExxonMobil finished 0.2% higher after dropping more than 1%, while refiner Valero closed down 1% after falling more than 4% earlier.
The sector has still trailed the broader market, shedding 3.5% over the past six months as the S&P 500 gained 16.3%, according to StockStory.
Occidental Petroleum has a $57.82B market cap and trades at 11.1x forward earnings, with Berkshire Hathaway remaining a major shareholder. Revenue has grown at an average annual rate of 8.4% over the past decade.
Permian Resources has roughly 450K net acres across West Texas and New Mexico and carries an $18.37B market cap. Kosmos Energy presents a different picture, with negative free cash flow and an EBITDA margin that has fallen 10.5 percentage points over five years.
What could ease the shortage
Supply has started recovering in some of the places where it disappeared, with Middle East diesel exports rising 30% in September from August. Chinese refiners have also added nearly 800K metric tons a month to global supply.
Those additions have yet to replace everything the market lost, with the Middle East shortfall still running at roughly 4M tons last month. The gap is narrowing, but the remaining shortage keeps pressure on industries that depend heavily on diesel.
Trucking, farming and shipping absorb those higher fuel costs while supply remains constrained. Treasury Secretary Scott Bessent said American farmers, truckers and businesses should not have to carry the burden of a global shortage.
Emergency reserves can add supply while disrupted exports recover, but they do not restore the production that disappeared from the Middle East and Russia. A more sustained easing in diesel prices depends on more supply returning to the market.
