Mike Wirth, CEO of Chevron, warned Sunday that the aviation industry faces deepening jet fuel shortages as Iranian military restrictions on shipping through the Strait of Hormuz continue to disrupt global energy supplies. The strait handles roughly one-fifth of the world's oil flows.
Wirth made the comments during an appearance on CBS News's "Face the Nation," noting that inventories of jet fuel in certain regions were already at seasonally low levels before the conflict began. He said Middle East refineries, which supply approximately 75 percent of Europe's imported jet fuel, have stopped exports due to the disruptions.
"It's not flowing today," Wirth told host Margaret Brennan, adding that reduced supplies would most directly impact airfares for consumers.
What the Left Is Saying
Progressive economists and Democratic lawmakers have pointed to the crisis as evidence of the need for accelerated investment in domestic energy production and alternative fuel sources. Environmental advocates within the party have argued the situation underscores vulnerabilities inherent in fossil fuel dependency, though many acknowledge that transitioning away from oil-based aviation fuels will take time.
Consumer advocacy groups aligned with Democrats have urged airlines to absorb some costs rather than pass them entirely to travelers. The Biden administration's Energy Department has not issued a formal statement on potential strategic petroleum reserve releases as of Sunday.
"This is exactly the kind of supply chain vulnerability that diversification and domestic production can address," said one Senate Democratic aide who spoke on condition of anonymity to discuss internal deliberations.
What the Right Is Saying
Republican leaders have framed the jet fuel shortage as a direct consequence of U.S. military operations in the Middle East, arguing that energy security should be prioritized alongside national security objectives. Some conservative commentators have called for removing regulatory barriers to domestic refinery expansion.
"We cannot afford to fight wars abroad while leaving American families vulnerable to price spikes at the pump and airport," said Sen. John Thune (R-S.D.), the Senate Republican whip, in a post on social media Sunday.
Conservative energy advocates contend that streamlined permitting for domestic production could help stabilize supplies more quickly than waiting for market corrections. Industry groups have also pressed for clarity on any potential administration actions to ease refinery constraints.
What the Numbers Show
The numbers illustrate the rapid escalation of costs since late February. According to the Argus U.S. Jet Fuel Index published by Airlines for America, jet fuel prices in the United States rose from $2.50 per gallon the day before U.S.-Israel strikes on Iran began to $4.19 per gallon as of Friday—a 67.6 percent increase.
Global average jet fuel prices fell 6.7 percent last week relative to the prior week, according to the International Air Transport Association, suggesting some market stabilization may be underway internationally.
Airlines have begun adjusting schedules in response. United Airlines CEO Scott Kirby said the carrier would cut approximately 5 percent of planned routes during the second and third quarters. Delta Air Lines has also announced plans to reduce summer flights, USA Today reported earlier this week.
Average U.S. airfare rose by more than $7.57 from February to March, according to Bureau of Labor Statistics data compiled by the Federal Reserve Bank of St. Louis. The Chevron CEO's prediction that conditions may worsen suggests further increases could follow.
The Bottom Line
The Strait of Hormuz situation remains fluid. The U.S. Navy has enforced a blockade of the waterway since April 13, and Iranian restrictions on commercial shipping continue to constrain jet fuel supplies globally. Markets are showing some signs of stabilization internationally, but U.S. domestic prices remain significantly elevated.
Airlines have already begun cutting routes and raising fares in response to higher fuel costs. Travelers booking summer flights may face both higher prices and more crowded planes if carriers maintain reduced schedules while demand remains strong. Industry observers will watch whether additional carriers announce schedule reductions in the coming weeks, and whether administration officials consider releasing strategic reserves to address domestic price pressures.
