• President Trump's prediction that gasoline and diesel prices will soon "come plummeting down" remains a promise, not an established market trend.
  • Gasoline has seen modest relief, but diesel remains persistently expensive, with war-related supply disruptions outweighing efforts to expand supply.
  • Analysts expect prices to stay elevated through the midterm elections, throwing cold water on hopes for an imminent collapse.

A Promise vs. the Pump

President Donald Trump took to Truth Social (DJT) this week to declare that gasoline and diesel prices will soon "come plummeting down," but the latest market data paints a more stubborn picture. As of October 26, the national average for regular gasoline stood at approximately $4.29 a gallon, while diesel was mired near $6.35 a gallon, according to AAA. The figures represent a modest decline from recent peaks but remain far above pre-war levels, when gasoline averaged $2.98 a gallon.

The administration has ramped up efforts to tame fuel costs ahead of the November 3 midterm elections. On October 22, Trump announced a $150 million Defense Production Act initiative aimed at expanding or modernizing refining capacity. A White House statement three days later reiterated that prices would fall rapidly, citing additional supply, fuel-rule waivers, and international agreements. Those are administration claims about expected results, not confirmation that large price cuts have materialized.

Diesel Stays Stubbornly High

The price evidence is mixed. GasBuddy's October 26 average for gasoline was $4.24, down 22.3 cents from a month earlier—a meaningful but gradual decline, not a collapse. Diesel, however, fell just 9.7 cents to $6.276 in the EIA's October 19 weekly reading, after hitting a record $6.523 in September. Regional disparities are stark: Gulf Coast gasoline averaged $3.784, while the West Coast topped $5.557, with California diesel at a staggering $8.242.

The core constraint is global. The U.S. produces more refined products than it consumes, but prices remain tethered to international crude markets, where disruptions from the Iran conflict and the Russia-Ukraine war have tightened supplies. Brent crude traded near $116 a barrel on October 23, while West Texas Intermediate hovered around $103, according to CBS (SKYD).

Refining Bottleneck

Even with domestic refineries operating "all-out," according to the American Fuel & Petrochemical Manufacturers, the industry faces physical limits. Energy analyst Tom Kloza told CBS that restoring refining units generally takes months or calendar quarters, meaning the new government funding is unlikely to deliver immediate relief. GasBuddy analyst Patrick De Haan was even more blunt, telling CBS he expected little short-term impact from the $150 million program.

The administration has also turned to international measures: a reported agreement to obtain Russian diesel—a notable reversal of years of U.S. pressure on Moscow—and a G7 commitment to release 100 million barrels from stockpiles. A temporary Jones Act waiver and fuel-specification waivers have been deployed to ease logistics, but these steps have yet to reverse the broader trend.

Political Fallout

The stakes are immediate. Republicans are defending narrow congressional majorities, and a Reuters (TRI)/Ipsos (IPS.PA) poll from October 19 found Trump's overall approval at 31%, with just 23% approving of his economic management. Fuel costs were among voters' top concerns.

A politically charged comparison emerged on October 26: Reuters reported that average gasoline prices during Trump's second term had reached $3.472 a gallon, marginally above the $3.471 average during Biden's presidency—a difference of one-tenth of a cent over different time periods. Diesel averaged $4.343 under Trump versus $4.078 under Biden.

Outlook

De Haan expects national gasoline prices to remain above $4 and diesel above $6 heading into the election, describing hoped-for relief as elusive. "We're not going to see a dramatic drop anytime soon," he said, according to CBS. University of Houston energy economist Ed Hirs cautioned that disruption could keep prices elevated for months even if fighting stopped immediately.

For now, the promised plunge remains just that—a promise. Whether it becomes reality depends less on announcements and more on restored international supply, reliable shipping, and usable refining capacity. The administration's $150 million initiative may improve resilience over time, but it is not an instant substitute for functioning global energy flows.
