Key Highlights
- American motorists are paying over $4 per gallon at the pump for the first time since the summer of 2022, with the national average reaching $4.018.
- Global oil benchmarks have experienced approximately 50% gains in the last 30 days following the outbreak of U.S.-Iran military conflict.
- Federal emergency measures relaxing ethanol blending rules and maritime shipping regulations have failed to curb rising fuel costs.
- Commercial diesel fuel prices reached $5.45 per gallon, representing an unprecedented monthly increase.
- Investment bank Goldman Sachs elevated its Brent crude projection to $115 for April delivery, while market observers suggest potential $200 levels if hostilities persist.
American consumers reached a significant price threshold this week as gasoline costs exceeded $4 per gallon nationwide, a level not witnessed since the late summer months of 2022. Industry tracking firm GasBuddy reported the national average settled at $4.018 per gallon, representing the steepest monthly price acceleration in recorded history.
The dramatic escalation stems directly from the continuing military engagement between the United States and Iran, which has now entered its fifth consecutive week. Throughout this period, both Brent crude and West Texas Intermediate benchmarks have experienced approximately 50% valuation increases, with Brent hovering around $107.80 per barrel while WTI trades near $102 per barrel.
Compared to this time last year, drivers are spending roughly $1 more per gallon. The bulk of this increase materialized following the commencement of military operations.
The commercial transportation sector faces even steeper challenges. Diesel fuel averaged $5.45 per gallon nationally on Tuesday, matching gasoline’s unprecedented monthly surge, according to GasBuddy’s tracking data.
GAS PRICES SURGE PAST $4 AMID WAR
US gasoline has topped $4 per gallon for the first time since 2022, rising over $1 in a month as the Iran war disrupts global oil supply. Crude prices have climbed above $100, pushing fuel costs sharply higher worldwide.
The spike is fueling…

In late March, federal authorities implemented emergency regulatory relief measures, including a waiver permitting expanded use of E15 gasoline—a more economical ethanol-blended fuel. Additionally, the administration suspended Jones Act maritime regulations for 60 days, which typically increase costs for domestic sea transport operations.
Despite these interventions, retail fuel prices have continued their upward trajectory without meaningful relief.
Critical Supply Route Concerns
Market analysts suggest that even with a swift resolution to hostilities, oil prices may remain elevated for an extended period. The central concern revolves around the Strait of Hormuz, a critical maritime passage that facilitated approximately one-fifth of worldwide petroleum and natural gas shipments prior to the current crisis.
According to sources within the administration cited by the Wall Street Journal, President Trump has indicated willingness to conclude military operations regardless of whether the Strait regains full operational capacity. Should this vital shipping channel remain compromised, petroleum prices are expected to maintain three-digit valuations.
Asian markets are experiencing particularly severe consequences. The majority of crude oil traversing the Strait was destined for Asian refining operations. In response to energy constraints, Bangladesh has closed educational institutions, while both Pakistan and the Philippines have implemented reduced working schedules to conserve energy resources.
Senior military officials, including Defense Secretary Pete Hegseth and Joint Chiefs Chairman Gen. Dan Caine, were scheduled to address the media Tuesday morning at 8 a.m. Eastern time.
Market Expert Forecasts
Goldman Sachs substantially revised its April Brent crude outlook upward from $85 to $115 per barrel, attributing the adjustment to prolonged supply disruptions and elevated risk premiums associated with the Strait of Hormuz situation. High-ranking Saudi Arabian government officials have developed contingency models projecting Brent at $180 should the conflict extend through April. Research analysts at Macquarie have projected the possibility of Brent surpassing $200 per barrel if military engagement continues into June.
Premium gasoline grades and aviation fuel are experiencing parallel price increases. While retail consumers face mounting costs, commercial diesel operators are absorbing even more substantial financial burdens.
Brent crude futures contracts were most recently valued near $107.61, showing modest gains during the trading session.
