Refiners at 98% Push Washington Toward a Wartime Law
With U.S. refineries at 98% utilization and diesel above $6 a gallon, the White House is weighing the Defense Production Act to add capacity. No decision yet.
The White House is weighing use of the Defense Production Act to add U.S. refining capacity after American refineries hit 98% utilization and diesel moved above $6 per gallon for the first time, with the idea raised at President Donald Trump's meeting with nearly a dozen refiners, Reuters reported.
The federal government is considering reaching for a Korean War-era industrial mobilization law to fix a bottleneck that no amount of crude oil can solve on its own. The White House has discussed invoking the Defense Production Act to add U.S. refining capacity, with American refineries already running at 98% of what they can physically process and diesel selling above $6 per gallon for the first time, according to OilPrice, citing Reuters.
The idea surfaced during President Donald Trump's recent meeting with nearly a dozen U.S. refiners. No decision has been made, and the discussions are expected to continue. But the mere appearance of the Defense Production Act in a conversation about gasoline and diesel supply says something about how tight the downstream energy system has become: the constraint is not barrels in the ground, it is the steel that turns them into fuel.
Why 98% Utilization Is the Number That Matters
Refinery utilization measures how much of a plant's rated crude processing capability is actually in use. At 98%, the system is effectively running flat out. Practically nothing is left in reserve for an unplanned outage, a hurricane, a fire, or a fouled unit — on the supplied figure, the cushion between current runs and nameplate capacity is about two percentage points, an illustrative reading of the gap rather than a reported spare-capacity number.
That has two consequences. First, any single incident at a large plant translates almost immediately into higher wholesale product prices, because there is no slack elsewhere to backfill the lost volume. Second, refiners have little room to change what they make. A plant running at the top of its range cannot simply pivot to more diesel without giving up gasoline or jet fuel; the yield choices get harder, not easier, as utilization climbs.
Diesel above $6 a gallon is the visible symptom. Diesel is the fuel of freight trucking, rail, agriculture, construction and marine shipping, which is why its price feeds into the cost of almost everything that moves. It is also the product most exposed to a squeeze in refining capacity, because distillate yields are constrained by the configuration of the units that make them.
What the Defense Production Act Could and Could Not Do
The Defense Production Act gives the executive branch tools to direct industrial output and to channel federal money and priority into production the government deems essential. In practice it has been used to prioritize orders, allocate scarce inputs, and fund capacity. It is a procurement and allocation instrument, not a construction company.
That limitation is exactly the point the industry made in the room. Refining executives told administration officials that federal money would produce more barrels faster if it were spent expanding existing facilities rather than building something new. This is the unglamorous but correct answer. A brownfield expansion — debottlenecking a crude unit, adding hydrotreating, lifting the throughput of a distillate hydrocracker — uses land, permits, pipelines, tankage, docks, labor and utilities that are already in place. A greenfield refinery on the U.S. Gulf Coast is a multi-year permitting and engineering undertaking before the first pipe is welded.
So even in the most aggressive version of this policy, the volumes arrive in increments and on the timeline of turnarounds and capital projects, not in weeks. Anyone reading a DPA invocation as an immediate fix for pump prices is misreading the tool.
The Economics Refiners Have Spent a Decade Learning
There is a reason the U.S. refining fleet has not been racing to add capacity, and it is not permitting alone. Refining is a capital-intensive, cyclical business in which a plant built today must earn a return over decades — against a policy backdrop that has, for years, pointed toward declining domestic gasoline demand, electrification of light-duty transport and tighter emissions rules. Boards that approved expansions into that outlook have often been punished for it.
The current environment inverts that logic in the short run. Utilization at 98% and diesel above $6 means crack spreads — the margin between the cost of crude and the value of the refined products made from it — are doing the work of a subsidy. Owners of complex, distillate-heavy capacity are the ones capturing it. That is precisely why federal money is being debated: if margins alone were sufficient to pull forward investment at the pace Washington wants, there would be no conversation about a wartime statute.
The flip side is who bears the cost. Fuel-intensive users are absorbing the diesel price directly: trucking fleets, railroads, agricultural producers heading into harvest, construction contractors, and the utilities and industrials that lean on distillate for backup generation. For these buyers, a policy that adds refining capacity in 2028 does very little about a fuel bill due this month.
A Calm Tape and a Loud Policy Debate
Broad equity markets were not visibly rattled by the prospect. At the last trade on Friday, 11 September 2026, the S&P 500 tracker SPY closed at $764.29, up 0.85% from the prior close of $757.83, with a day range of $763.60–$766.38. The Nasdaq 100 proxy QQQ finished at $714.88, up 0.87%, and the Dow 30 vehicle DIA ended at $525.79, up 0.97%. The market is closed; those are last traded prices, not live quotes.
The disconnect is instructive. Index-level strength can coexist with a genuine industrial bottleneck, because the cost lands unevenly — concentrated in freight, food and construction inputs rather than spread across the largest listed companies. It also tends to show up in inflation data with a lag, which is the channel policymakers will be watching most closely.
What to Watch From Here
Three things will determine whether this becomes policy or stays a talking point. Whether the administration actually signs a DPA determination for refining, and how narrowly it is drawn. Whether any federal support is structured around brownfield expansion, as refiners requested, or diverted toward new-build projects that deliver later. And whether utilization stays pinned near its ceiling through the next round of scheduled maintenance — because if it does, the diesel market will keep setting the political clock.
For now the status is unambiguous: proposal discussed, no decision made, talks continuing.

Frequently asked questions
What is the Defense Production Act?
It is a Korean War-era U.S. law that lets the executive branch direct and support industrial output deemed essential, including prioritizing orders, allocating scarce inputs and funding capacity. It is an allocation and procurement tool rather than a construction program, so it can channel money and priority toward refining expansion but cannot itself build a plant quickly.
Why does 98% refinery utilization matter?
Utilization measures how much of a refinery's rated crude processing capability is in use. At 98% the U.S. fleet is running effectively flat out, leaving almost no cushion for unplanned outages, storms or maintenance problems. Any single incident then feeds straight into wholesale fuel prices because there is little spare capacity elsewhere to replace lost volume.
Has the White House decided to invoke the act?
No. According to Reuters reporting cited by OilPrice, the proposal was discussed at President Donald Trump's recent meeting with nearly a dozen U.S. refiners, but no decision has been made and the discussions are expected to continue. The story describes an option under consideration, not an announced policy.
What did refining executives recommend instead?
Refining executives told administration officials that federal money would produce more barrels faster if it were used to expand existing facilities rather than build new ones. Brownfield expansions reuse land, permits, pipelines, tankage and utilities already in place, while a new refinery requires years of permitting and engineering before any fuel is produced.
Who is most exposed to diesel above $6 a gallon?
Diesel powers freight trucking, rail, agriculture, construction and marine shipping, so the cost lands hardest on fuel-intensive users and eventually on the price of goods that move. Trucking fleets, farm operators heading into harvest and construction contractors absorb it directly, well before any capacity added under a federal program could arrive.
How did equity markets close on the day of the report?
At the last trade on Friday, 11 September 2026, the S&P 500 tracker SPY closed at $764.29, up 0.85% from a prior close of $757.83. The Nasdaq 100 proxy QQQ ended at $714.88, up 0.87%, and the Dow 30 vehicle DIA finished at $525.79, up 0.97%. Markets were closed thereafter.
