Factors Contributing to Current Gas Price Surge

The recent surge in gas prices has been attributed to a combination of global and domestic factors, with the ongoing war with Iran playing a significant role. The conflict has led to the effective closure of the Strait of Hormuz, a critical chokepoint through which one-fifth of the world’s crude oil passes, causing a major disruption in global oil supply ^[1][2][3].

As a result, crude oil prices have spiked, reaching as high as $112 per barrel in early April, which has directly impacted gasoline prices in the United States ^[1]. The national average for gasoline has risen from approximately $2.98 to over $4.50 per gallon, marking an increase of more than 50% since the onset of the conflict ^[1][3][4].

Gas station owners set prices at the pump, but these are heavily influenced by crude oil costs, refining margins, distribution expenses, and taxes ^[3][5][6]. Economists have noted a ‘rocket‑and‑feathers’ pattern in pricing, where gasoline prices rise quickly with crude oil price increases but fall more slowly when crude prices decline ^[3].

In California, gas prices are among the highest in the nation due to additional factors such as higher taxes, environmental regulations, unique fuel blends, and limited refinery capacity ^[7][8][9]. Governor Gavin Newsom has pointed to Chevron as a contributor to high prices, although there is no independent verification of price-gouging by the company ^[8].

Public opinion polls indicate that a significant portion of Americans hold President Donald Trump and his administration responsible for the high gas prices, with 48% of respondents attributing the situation to his policies ^[10][11][12]. This sentiment is shared across political lines, with majorities of Republicans, independents, and Democrats expressing similar views ^[11].

What Is Known

The war with Iran and the closure of the Strait of Hormuz have significantly disrupted global oil supply, leading to increased crude oil and gasoline prices ^[1][2][3]. Gasoline prices in the U.S. have surged more than 50% since the conflict began ^[1][3][4].

What Remains Unclear

While Governor Newsom has accused Chevron of price-gouging, there is no independent verification to support this claim ^[8]. Additionally, the extent to which gas station owners’ pricing strategies contribute to slow declines in pump prices remains debated among economists ^[3].
