How a ban of diesel exports could lead to higher prices — even in the U.S.

Lawmakers are pushing for a ban on diesel exports, seeking relief for truckers and farmers who are paying record high prices for the crucial fuel. But economists and oil experts say the plan could backfire — and lead to higher costs at the pump for Americans.

President Donald Trump said Tuesday that he’s calling for a ban on diesel exports, and his administration confirmed they are “examining” the issue.

The United States is the largest exporter of diesel in the world, sending on average 1.4 million barrels of distillate fuel a day to trading partners mainly in Latin America and Europe. Experts say that a blanket ban on shipments would imperil those economic allies and push domestic refineries to cut production. That, in turn, would almost certainly lead to higher gasoline prices.

Here’s what is being proposed and what could happen.

Why is a ban being considered?

Farmers and truckers are paying more for diesel than ever before. The national average hit $6.53 per gallon this week, according to the Energy Information Administration, well above the previous record of $5.81 set in June 2022 after Russia’s invasion of Ukraine.

Continued attacks in that region, as well as the U.S.-Israeli war in Iran, have compromised oil infrastructure globally, sending the price of diesel soaring.

That’s making it more expensive to produce food and move groceries, clothing and other items around the country, pressuring farmers and consumers. Politicians are looking for a way to lower those prices.

A ban might initially lower diesel prices in the U.S., analysts say. But the relief likely wouldn’t last long.

“It’s very, very temporary,” said Debnil Chowdhury, head of Americas and Europe fuels and refining at S&P Global Energy. “It would lead to higher gasoline...”

The US already produces substantially MORE DIESEL THAN WE CONSUME DOMESTICALLY. I just recently learned about this fact. Banning diesel exports makes no sense,

[Paladin2]

The USA is fairly vast.

Diesel Distribution infrastructure is not uniform.

You-rope has more Diesel cars and a surplus of straight-run gasoline.

The Eastern Seaboard apparently refines a surplus of Diesel to get the gas they need.

So there apparently has been a long history of transshipping gas to the USA and Diesel to You-rope.

....and still be cheaper than in Canadia and Europe.

I can see where it could raise prices... but in theory if diesel producers could only sell to American buyers then domestic prices should come down.

[Paladin2]

Consider the possibility of ‘Rat near term commodity traitors colluding to generate an “October Surprise” on Diesel pricing.

If producers are forced to sell at reduced cost, they usually find another product that will keep them profitable.

reduced PRICE.

"Theory predicts a short-term domestic price drop from the supply shift. Reality adds inventory limits, co-production of other fuels, transport bottlenecks, and a feedback loop through lower refinery runs and tighter global markets. The net result that most recent analyses point to is temporary localized relief followed by reduced overall fuel production and higher (or at best mixed) prices for American consumers and businesses. That is why industry groups, many economists, and market observers describe an export ban as likely to raise rather than lower the broader cost of fuels over time."

No diesel may be exported if in the past ten days EST the EIA US Gulf Coast Wholesale Reference price of diesel was above $4/gallon (that’s without taxes, delivery and retailer markup).

or perhaps

No diesel may be exported if in the past ten days EST the retail price of diesel as measured by presidential directive was above $5.20/gallon.

You either believe in the free market, or you don’t.

If you don’t, then let’s start price-controlling everything.

In theory, that should prevent inflation.

“You either believe in the free market, or you don’t.”

There is no free market in diesel (and just about everything else).

The EU, UK and Iran are all working hard to force Republicans to lose control of Congress.

Sadly, a lot of people here do not believe in the free market.

It’s a global market

[MMusson]

SUPPLY AND DEMAND has not been repealed.

If we ban exports and we have more than enough domestic production, PRICES WILL FALL. At least in the short term.
