White House weighs the Defense Production Act to expand US refining

The White House is weighing how to use the Defense Production Act to expand US oil refining capacity, Reuters reported on Friday, citing two sources^1,7. The idea was discussed during a recent meeting between President Donald Trump and nearly a dozen US oil refiners^5,9. Coverage of the reporting describes the administration as evaluating whether to invoke the act for refining capacity for the first time¹⁰.

American refineries are already running at 98% utilization^2,3. Officials frame the question as a consequence of the conflict with Iran, which has exposed the limits of the domestic refining system^1,8. Nothing has been decided: the accounts describe the White House as mulling ways it could use the act rather than having settled on one^6,11.

Why it matters to investors

The trigger is diesel. The US national average diesel price crossed six dollars a gallon for the first time¹², and prices soared past that level on Friday¹⁵. The record is the backdrop to the administration’s search for levers^4,14.

BofA called record-high diesel a real-economy pressure point that is flashing a warning, noting that inflation is weighing on consumer sentiment and continues to outpace wage growth¹³. Diesel sets the cost of moving freight, so a record price passes through the goods economy rather than sitting in one sector. Energy stocks closed mixed as the report circulated¹¹.

What to watch

Refining capacity cannot be added quickly, which is why the shorter-dated levers matter more to prices in the near term. Beyond another release from the Strategic Petroleum Reserve, an export ban is one of the few remaining tools available¹⁵. An export restriction would land directly on refiner margins, which is the opposite of what an expansion of capacity is meant to achieve.

The administration’s public line is that supply policy is already working. Interior Secretary Doug Burgum told Newsmax on Thursday that the president’s push to expand domestic energy production has helped keep prices down¹⁶. That sits awkwardly beside a record diesel price and refineries with almost no spare capacity^2,12.

The war remains the variable underneath all of it. The same day’s coverage tied the diesel record to Houthi advances along the Red Sea¹⁴, and the White House review was reported alongside shipping disruption and Houthi gains⁹. Any use of the Defense Production Act for refining would mark a material step beyond price rhetoric and into direct industrial intervention^4,10.
