U.S. refiners are not rushing to build new plants despite record margins, even as President Donald Trump presses Chevron, Marathon Petroleum, Valero Energy, PBF Energy and Delek US Holdings to lower gasoline prices. AAA's national average hit $4.14 a gallon on Sept. 3, 2026, the first Labor Day on record above $4. The bottleneck is crude, not refining capacity: U.S. plants already run near 98% utilization, and the price spike traces to the Strait of Hormuz conflict, not a structural shortfall. This is analysis, not advice.

The Meeting: Five Refiners, No Exxon

President Donald Trump met with U.S. refining and fuel-distribution executives at the White House on Sept. 1, 2026, pressing them for what a White House official described to Reuters as "concrete, near-term steps" to lower gasoline prices. Invited companies included Chevron, Marathon Petroleum, Valero Energy, PBF Energy and Delek US Holdings; Exxon Mobil was not invited, per Reuters reporting relayed by CNBC. Energy Secretary Chris Wright, Interior Secretary Doug Burgum and National Energy Dominance Council director Jarrod Agen also attended, according to CNBC.

The Price Backdrop: First $4 Labor Day on Record

The pressure on refiners comes as AAA's national average hit $4.14 a gallon on Sept. 3, 2026 — the first Labor Day on record above $4, eclipsing the prior holiday high of $3.82 set in September 2012, per AAA's newsroom. The EIA's separate weekly survey put the average slightly lower, at $4.071 a gallon as of Aug. 31, 2026. Both trackers show prices roughly a dollar above year-ago levels, consistent with CNBC's reporting of a $3.19 comparison from a year earlier.

Why Prices Spiked: A War, Not a Refining Shortfall

Crude, not refining capacity, is behind the run-up: WTI traded near $90-93 a barrel this week, up sharply from about $67 on Feb. 28, 2026 — the date OilPrice.com identifies as the start of the current conflict — amid continued volatility around the Strait of Hormuz, per Forbes Advisor's Sept. 3 market report. Coverage of the White House meeting, including from The Hill, tied elevated pump prices to that broader conflict rather than to a U.S. refining shortfall. Pump prices track crude with a lag.

The Refiners' Case: Record Margins, a Bet Nobody Wants to Make

Despite a surge in refining margins, executives are not rushing to build new U.S. plants, industry analysts told OilPrice.com. "Nobody's going to go out and make a huge multibillion-dollar investment based on three months of record margins," said Robert Campbell of Energy Aspects. A new refinery takes roughly five years to reach production, and forecasters cited by OilPrice.com expect U.S. fuel demand to plateau or decline by the time one could open — turning today's strong margin into a speculative long-term bet.

Where the Barrel Actually Is: Refineries Already Running Flat Out

U.S. refinery utilization has held above 95% for three straight months — the longest such run since 2000, per OilPrice.com's analysis of EIA data — reaching roughly 98% nationally by late August. Globally, an estimated 7-8 million barrels a day of refining capacity is reported offline across Asia, the Middle East and Russia, leaving little near-term global slack to import processed fuel into the U.S. even if American plants can't add more throughput.

What Washington Can Actually Move

A White House official said the administration is seeking near-term fixes — regulatory changes and faster permitting at existing plants — rather than betting on refineries that would not open for years, per Reuters reporting via CNBC and Bloomberg. Whether faster permitting meaningfully moves pump prices before the Strait of Hormuz conflict resolves is unconfirmed and worth watching. This is analysis, not advice.
