Diesel prices are swinging hard — and even JPMorgan says it doesn't see a clear resolution. John Kingston breaks down the 25-cent futures move, the export ban talk, and why New England, the Gulf Coast and the West Coast would not feel it the same way.If you run freight, buy fuel or watch margins, this is the takeaway: a diesel export ban may look like relief up front, but the regional fallout could make things worse.#DieselPrices #EnergyMarkets #FreightWaves

Talk of a U.S. ban on diesel exports is gaining political traction, but the policy could create sharply uneven outcomes across regions rather than delivering broad price relief — and it would almost certainly trigger refinery run cuts that reduce overall fuel supply, according to FreightWaves energy reporter John Kingston.

The export ban discussion comes as diesel futures swung through a 25-cent range in a single session, a move Kingston attributed in part to President Trump's remarks at the United Nations about potentially "annihilating" Iran, the world's fourth or fifth largest oil producer. "Talk of annihilating the world's 4th or 5th largest oil producer is always going to be bullish," Kingston said. "That's just the way it is."

The U.S. has not banned the export of any commodity since lifting its crude oil export ban in 2015 following the shale boom. Kingston said the structural problem with a diesel export ban is the country's regional supply imbalance: New England has no nearby refineries and depends heavily on imports from Europe. Banning U.S. exports would tighten European supply, making those imports more expensive or scarce, while the Colonial Pipeline — which moves product from the Gulf Coast to New York Harbor — is likely already running at full capacity and cannot absorb additional volume.

"You can imagine some truck drivers sort of reveling in an export ban, because it will flood certain markets with lots of oil, and it'll leave other markets starved," Kingston said.

The West Coast faces a similar problem: Gulf Coast diesel cannot reach it easily without transiting the Panama Canal, a lengthy and costly routing. Kingston added that tanker rates are currently "off the charts," further limiting the ability to redirect barrels even with a Jones Act waiver in place.

A ban would also remove a key incentive for refiners to keep output high. Refiners have been running at maximum capacity because diesel and gasoline margins are exceptionally profitable. Losing export market access would prompt run cuts, reducing supplies of diesel, gasoline, jet fuel, and heating oil simultaneously. Kingston noted that refinery seasonal maintenance is already set to reduce system-wide output, compounding the effect. JP Morgan's commodity research team underscored the broader uncertainty last week, issuing a report that acknowledged it sees no resolution to elevated energy prices — a notable admission from a major Wall Street bank whose analysts had identified $100 Brent crude, a 5-handle on the 10-year Treasury yield, and $4 gasoline as red lines that would prompt a policy shift, none of which proved decisive.

On the trucking regulatory front, Kingston noted the federal government has issued a first-of-its-kind nationwide hours-of-service waiver for fuel haulers since the COVID-era waiver that ran for more than a year and a half. He also flagged the ongoing Lujan case regarding commercial driver's licenses and upcoming appearances at the Trimble Users Meeting in San Diego and an NMFTA cybersecurity conference in Long Beach, where artificial intelligence's role in freight system security is expected to be a central topic.

• A U.S. diesel export ban could flood Gulf Coast spot markets while leaving East Coast and West Coast consumers undersupplied due to pipeline and tanker constraints.

• JP Morgan's commodity research team publicly said last week it sees no resolution to high energy prices, noting that $100 Brent, $4 gasoline, and a 5-handle on the 10-year yield failed to shift administration policy.

• Refiners running at full capacity to maximize profits would cut production runs if export markets are restricted, reducing supplies of gasoline, jet fuel, and heating oil alongside diesel.
