Key Takeaways
- The national average price for gasoline in the United States exceeded $4 per gallon on Tuesday, reaching $4.018 – the first time since August 2022.
- Benchmark crude oil prices have jumped approximately 50% in the last month following the outbreak of the US-Iran military conflict.
- Emergency waivers from the Trump administration targeting ethanol rules and Jones Act shipping regulations have failed to reduce consumer prices.
- Diesel fuel reached $5.45 per gallon, representing another record monthly increase.
- Goldman Sachs has revised its Brent crude projection upward to $115 for April, while some market watchers suggest prices could reach $200 if hostilities extend into June.
American motorists hit a significant economic threshold on Tuesday as fuel prices at the pump climbed above $4 per gallon nationwide for the first time in nearly three years. According to GasBuddy, a leading petroleum data analytics firm, the national average reached $4.018 per gallon – representing the most dramatic monthly price surge in recorded history.
The spike is intrinsically linked to the continuing military confrontation between the United States and Iran, which has now extended into its fifth week. During this period, both major crude oil benchmarks – Brent crude and West Texas Intermediate – have experienced approximately 50% increases in value. Current trading shows Brent hovering near $107.80 per barrel while WTI sits around $102 per barrel.
Comparing current pump prices to those from twelve months ago reveals an increase of roughly $1 per gallon. The overwhelming majority of this escalation has occurred since military operations commenced.
The commercial trucking sector faces even more severe financial pressure. Diesel fuel prices reached a national average of $5.45 per gallon on Tuesday – another unprecedented monthly gain 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 Trump administration attempted intervention on March 25 by issuing emergency regulatory relief on federal ethanol mandates affecting E15 gasoline blends, which typically offer lower costs to consumers. Additionally, the White House suspended Jones Act maritime shipping regulations temporarily for 60 days, rules that typically increase domestic transportation expenses.
Despite these administrative actions, consumers have yet to experience any measurable relief at filling stations nationwide.
The Strait of Hormuz Bottleneck
Market analysts suggest that even a near-term cessation of hostilities may not translate to rapid oil prices declines. The critical factor remains the Strait of Hormuz, a maritime chokepoint that facilitated approximately 20% of worldwide oil and natural gas shipments before the conflict erupted.
According to administration sources cited in a Wall Street Journal report, President Trump has indicated to advisers his openness to reducing military operations even if the Strait remains substantially closed to commercial traffic. Should this vital shipping channel continue experiencing disruption, petroleum prices may persist at or near current triple-digit levels.
The consequences are reverberating throughout Asia, where the majority of crude oil transiting the Strait was destined for regional refineries. Bangladesh has temporarily closed its universities, while both Pakistan and the Philippines have implemented reduced workweek schedules to better manage energy consumption.
Defense Secretary Pete Hegseth alongside General Dan Caine, Chairman of the Joint Chiefs of Staff, were slated to conduct a media briefing Tuesday morning at 8 a.m. Eastern time.
Market Expert Perspectives
Investment banking giant Goldman Sachs has substantially revised its Brent crude oil forecast for April, raising its projection from $85 to $115 per barrel. The firm attributes this adjustment to prolonged disruption supporting elevated risk premiums connected to Strait of Hormuz uncertainties. Senior officials within Saudi Arabia’s government have conducted internal modeling scenarios placing Brent at $180 should the conflict persist through April. Analysts at Macquarie Group have projected that Brent could potentially breach $200 per barrel if military operations continue into June.
Premium gasoline grades and aviation fuel are experiencing parallel price increases. While consumer pain at retail fuel pumps is substantial, commercial operators purchasing diesel are confronting even steeper cost burdens.
Brent crude futures contracts were most recently changing hands near $107.61, showing modest gains during the trading session.
