Chevron CEO Mike Wirth has issued a warning that the aviation industry's current jet fuel supply crunch is likely to worsen in the coming weeks, primarily due to disruptions linked to the Iran war and constrained shipping through the Strait of Hormuz, a vital oil transit route responsible for about one-fifth of global supply [1]. Wirth noted that jet fuel inventories in key regions were already at seasonally low levels before the conflict, leaving markets particularly vulnerable to supply shocks [1].
Jet fuel prices have surged sharply since late February, with U.S. prices rising from approximately $2.50 per gallon before the conflict to $4.19 per gallon as of April 24, according to Airlines for America [1]. Globally, prices remain volatile; the International Air Transport Association reported a 6.7% week-over-week decline to $184.63 per barrel, despite ongoing supply pressures [1].
Airlines are responding to these higher costs by adjusting operations. United Airlines announced plans to cut about 5% of its planned capacity for the year, while Delta Air Lines has trimmed its growth plans by roughly 3.5 percentage points [1]. United Airlines is also raising ticket prices by up to 20% as fuel costs surge [1]. Fuel typically represents about a quarter of airline operating costs, making carriers highly sensitive to price swings. As a result, airlines are reducing lower-margin routes and increasing fares and fees to offset rising expenses [1].
Consumers are already feeling the impact, with Bureau of Labor Statistics data showing airfares rose month over month in March—a trend expected to accelerate as airlines pass on higher fuel costs and limit capacity ahead of the peak summer travel season [1]. Wirth emphasized that the core issue is the disrupted energy flows through the Strait of Hormuz, with reduced shipments from Middle Eastern refiners tightening jet fuel availability across Europe and Asia [1]. He also highlighted that depleted inventories have eroded the global energy system's flexibility, making it harder to absorb shocks [1]. Even if flows resume, Wirth cautioned that it could take time for supply chains and inventories to normalize [1].
CONCLUSION
The jet fuel supply crisis, exacerbated by the Iran war and disruptions in the Strait of Hormuz, is driving up costs for airlines and consumers alike. With airlines cutting capacity and raising fares, and Chevron's CEO warning of further tightening, the aviation sector faces significant near-term challenges. Market participants should brace for continued volatility and higher travel costs as the situation unfolds.
