Diesel prices are an economic time bomb

A war with Iran closed the Strait of Hormuz, spiking diesel costs. Truckers and farmers feel it first, but grocery stores and holiday shopping will follow within weeks.

In brief

A war with Iran closed the Strait of Hormuz, spiking diesel costs. Truckers and farmers feel it first, but grocery stores and holiday shopping will follow within weeks.

Gasoline gets attention, diesel doesn't

US-ECONOMY-DIESEL

Everyone watches gasoline prices and their effect on the economy. But diesel fuel powers shipping, agriculture and heavy industry, and its recent spike will hit consumers harder than most realise.

How diesel reaches your wallet

Nathan Bomey, a business reporter at Axios, explains that most American products are shipped by truck. Diesel prices directly affect trucking costs, which then trickle down to consumers through higher prices.

Iran war disrupts global energy

The US and Israel attacked Iran, leading to closure of the Strait of Hormuz. This disrupted global energy supplies and spiked prices for diesel, gasoline, jet fuel and all crude oil-based products.

Truckers and farmers are panicking

Truckers and farmers are panicking

Truckers face much higher costs of doing business. Farmers already pressured by trade wars and climate issues now face additional diesel costs, which they pass on through higher food prices to consumers.

Grocery prices will spike within weeks

Bomey says the impact is imminent, arriving within weeks not months. Fresh food shipped weekly will see price increases first, hitting grocery aisles before consumers notice elsewhere.

“We're not talking about months; we're talking about weeks, if not days, before people will start to notice increases, especially in the grocery aisle.”

Holiday shopping will cost more

The holiday shopping season arrives as diesel prices peak. Toys made with crude oil-based resin and shipped by diesel truck will all cost more, adding up to higher prices across retail.

Heating oil adds winter pressure

Heating oil, used primarily by Northeast households, is caught in the same oil price vortex as diesel. Households face higher heating costs alongside food and consumer goods inflation.

Switching fuels takes time

Trucking companies could theoretically switch to alternatives like rail, compressed natural gas or biodiesel. But they are heavily invested in diesel trucks and cannot switch quickly without scrapping huge investments.

Tesla Semi finally arrives

Tesla began major production of the Tesla Semi, an electric semitruck debuted in two thousand eighteen. Electric trucks offer an alternative, but their heavy batteries limit cargo capacity compared to diesel.

Electric trucks have weight limits

The Tesla Semi's battery is so heavy it struggles with heavy cargo. When it first shipped products, it carried light items like bags of Cheetos. Battery weight remains a constraint on electric truck capacity.

Refineries are the big winners

Refineries that convert crude oil into usable diesel are profiting from high prices. Limited refining capacity worldwide due to issues in Russia, Iran and elsewhere lets them charge higher prices and earn more.

Consumer spending masks real pain

Consumer sentiment is at rock bottom but spending remains strong. Bomey warns people will hit a breaking point if underlying economic fundamentals collapse, as they cannot sustain this spending level indefinitely.

The one thing

Diesel prices have surged after the US and Israel attacked Iran, closing the Strait of Hormuz. The spike will ripple through groceries and consumer goods within weeks.
