TLDR
- National gas prices reached $3.54 per gallon on March 10, marking an 18-month peak
- Fuel costs have climbed 21% in 30 days, adding 50+ cents since conflict with Iran started Feb. 28
- Critical Strait of Hormuz chokepoint, responsible for 20% of worldwide oil transit, stays largely blocked
- Crude prices fluctuated dramatically from near $120 to approximately $84–$85 per barrel in days
- Industry experts predict fuel costs will remain elevated due to rising seasonal consumption
American motorists are experiencing their steepest fuel expenses in more than a year and a half. AAA reports the nationwide average reached $3.54 per gallon on March 10—a 21% increase from 30 days earlier.
This dramatic escalation stems from the military confrontation between the U.S. and Iran, which commenced February 28 following coordinated American and Israeli military operations against Iranian targets. The hostilities have severely impacted the Strait of Hormuz, a critical maritime passage handling approximately one-fifth of global petroleum shipments.
According to GasBuddy tracking, Americans paid an average of $2.98 per gallon immediately before hostilities erupted. This translates to consumers spending over 50 cents more each time they refuel their vehicles.
Bespoke Investment Group’s analysis indicates the previous week’s 72-hour price spike represented the steepest increase observed since Hurricane Katrina devastated the Gulf Coast in 2005.
Global crude oil prices have experienced tremendous swings. Brent crude skyrocketed toward $120 per barrel early Monday morning before retreating to approximately $85 following presidential statements suggesting imminent conflict resolution. West Texas Intermediate has climbed roughly 25% since late February.
Why Gas Prices Are Staying High
Despite crude’s retreat, pump prices haven’t followed suit—at least not immediately. GasBuddy’s Patrick De Haan anticipates prices will plateau between $3.55 and $3.65 per gallon over the coming 24 to 36 hours.
Two primary factors keep prices elevated. Retail stations don’t instantly translate lower crude costs into pump discounts. Additionally, consumption patterns shift upward as spring vacation season commences and milder temperatures encourage increased driving.
Regulatory requirements also mandate retailers transition to costlier summer-formulation gasoline, mandated from June 1 through September 15. This seasonal reformulation typically adds approximately 15 cents per gallon to consumer costs.
De Haan emphasized that elevated pricing will persist while the Strait of Hormuz remains inaccessible. Iranian officials threatened last week to ignite passing tankers, and Bloomberg’s maritime monitoring confirmed the waterway stayed predominantly closed through Tuesday.
What Comes Next
Aramco CEO Amin Nasser characterized the situation as the most severe emergency the region’s petroleum sector has encountered. “While we have faced disruptions in the past, this one by far is the biggest,” he said.
Raymond James analyst Bobby Griffin indicated that assuming crude stabilizes, fuel retailers will experience compressed margins for several weeks before normalization occurs.
Iran’s foreign minister stated Tuesday that the nation was ready to continue military operations and dismissed prospects for diplomatic engagement with Washington.
As of Tuesday, Defense Secretary Pete Hegseth called it the “most intense day of strikes” on Iran. President Trump said the U.S. could act to protect shipping in the strait.
The Strait of Hormuz remained effectively closed as of March 10, with the exception of some Iran-linked vessel traffic.
