US gasoline prices have come under renewed political scrutiny after President Donald Trump ordered an investigation into major oil companies, accusing them of failing to pass lower oil costs on to consumers despite easing pressures in global energy markets.
The move follows months of disruption in the oil market after Iran blocked tanker traffic through the Strait of Hormuz, one of the world's most important energy trade routes, in response to US-Israeli military strikes in February. The disruption triggered a sharp rise in global petroleum prices and fuel costs, intensifying concerns over inflation and energy affordability across the United States.
Announcing the investigation on Wednesday, Trump claimed oil producers were not reducing fuel prices in line with falling crude costs.
"The big oil companies are not dropping their price at the pump commensurate with the sharply lower prices they are paying for Oil," he wrote on Truth Social.
"Those prices are dropping like a rock! In other words, customers are being 'gouged'," he added.
Fuel prices remain a politically sensitive issue in the United States, where petrol-powered vehicles are the primary mode of transport for millions of people. The administration has faced growing criticism over the economic consequences of the Middle East conflict, particularly as congressional elections approach in November.
Trump has repeatedly argued that energy prices would rapidly decline once hostilities eased. However, many economists have challenged that assessment, warning that oil markets typically take time to absorb supply disruptions and restore price stability. Analysts expect crude and fuel prices to remain above pre-war levels for some time, despite recent improvements in supply conditions.
Tehran and Washington have since reached an initial agreement that includes the resumption of oil tanker traffic through the Strait of Hormuz, helping to ease concerns over global fuel supply. Nevertheless, broader disputes, including Iran's nuclear programme, remain unresolved.
Although gasoline prices have fallen since the announcement of the preliminary agreement, they remain elevated compared with levels before the conflict. According to the AAA motor club, the average price of a gallon of regular gasoline stood at $3.93 on Tuesday.
The dispute highlights the continuing link between geopolitical tensions, global oil supply chains and domestic energy costs. With fuel prices feeding directly into inflation, transport expenses and household budgets, developments in the oil market remain a key political and economic issue for the United States.
The president has also faced criticism from opponents who argue that billions of dollars in public spending linked to the Middle East conflict have coincided with higher fuel costs and rising inflation at home, adding further pressure on the administration's economic record.
