Trump invokes Defense Production Act to boost U.S. oil production and refining capacity amid post-Iran strike fuel price surge
President Trump invoked the Cold War-era Defense Production Act this week, directing financial incentives toward U.S. oil production, refining, pipelines, and liquid fuel storage. The presidential memo marks a significant federal intervention in energy markets — one driven by a sharp rise in crude oil and diesel prices following joint U.S. and Israeli strikes on Iran at the end of February.
Trump signs memo invoking Defense Production Act for energy
The memo authorizes financial incentives across several energy sectors: oil production, refining, pipelines, and liquid fuel storage. It gives the administration broad authority to channel federal support toward projects it considers critical — though it stops short of naming any specific initiatives that would actually receive funding.
The move comes as the U.S. already leads the world in crude output. The country averaged around 13.6 million barrels of daily crude production in 2025, making it the largest producer globally. Even from that position, the administration concluded that existing market conditions weren’t enough to guarantee adequate supply at stable prices.
Trump signed legislation last year that included $1 billion in Defense Production Act funding for energy projects deemed critical to national security.
By invoking the Defense Production Act, Trump is framing energy supply as a matter of national security, not just an economic issue. That framing significantly expands the tools available to the federal government — and signals the administration is prepared to use them.
Why Trump acted: Energy price surge and supply disruptions
The trigger for the memo isn’t hard to identify. Crude oil and diesel prices surged after U.S. and Israeli forces struck Iran in a joint operation at the end of February, and the conflict that followed has curtailed energy shipments across global markets at a moment when demand remains steady.
A separate disruption has compounded the problem. Ukrainian attacks on Russian refineries have added to fuel shortages worldwide, layering pressure onto already strained markets. Two distinct supply shocks — one in the Middle East, one in Eastern Europe — have left global fuel markets with very little cushion.
The memo acknowledged these structural vulnerabilities directly, citing constrained financing, long lead times, permitting bottlenecks, and supply chain limitations as core reasons the U.S. can’t expand energy output quickly enough on its own. That framing signals the administration sees this as more than a short-term price spike — it’s a deeper gap between existing infrastructure and the capacity to respond to sudden disruptions.
Political and economic consequences of rising energy costs
Energy prices don’t stay abstract for long. When fuel costs rise, you feel it at the gas pump, in grocery prices, and in utility bills. That kind of everyday visibility makes energy a potent political issue — and right now, it’s working against Trump.
Republicans are heading into the November 3 congressional elections hoping to hold onto both chambers. Surging fuel costs complicate that goal considerably. Voters who feel squeezed at the pump tend to hold the party in power responsible, regardless of what’s actually driving prices.
The polling reflects that pressure. A Reuters/Ipsos poll that closed Monday shows just 36% of Americans approve of Trump’s handling of the economy — a number the administration will want to move before November. Stabilizing energy prices is one of the more direct levers available. Invoking the Defense Production Act is partly a policy response and partly a political signal, telling voters the administration is acting even if the practical effects won’t be felt immediately.
Background: prior use of the Defense Production Act for energy
This week’s memo didn’t come out of nowhere.
Trump signed legislation last year that included $1 billion in Defense Production Act funding for energy projects deemed critical to national security. That bill established a precedent for using the Act as a financing mechanism for domestic energy infrastructure — not just an emergency tool, but a longer-term investment vehicle. The groundwork, in other words, was already laid.
More recently, Vice President JD Vance announced last week that the administration would use the Defense Production Act to expand capacity at a Texas refinery owned by Delek US Holdings — a preview of the broader direction the administration was already heading. The Defense Production Act itself dates to the Korean War era; Congress passed it in 1950 to give the executive branch the ability to mobilize industrial production during national security emergencies, and over the decades it’s been invoked for everything from military procurement to pandemic-era medical supply chains.
What this means for U.S. energy policy
Taken together, this week’s memo, last week’s Vance announcement, and last year’s legislation point to a consistent strategy: using the Defense Production Act as an active tool for shaping domestic energy infrastructure rather than leaving it as a dormant emergency power.
The memo’s lack of specifics means real-world impact will depend entirely on implementation — which projects get funded, how quickly money moves, and whether the incentives are enough to accelerate production and refining capacity in any meaningful timeframe. With fuel prices elevated and elections approaching, the pressure to show results is real.
