Gasoline Hits $4.48 — Up 50% Since Iran War Started
Pump prices jumped 31 cents in a week as conflict drives fuel costs to levels not seen since 2022, squeezing owner-operator margins on every deadhead mile.
Regular gasoline averaged $4.48 per gallon on May 5, according to AAA — a 31-cent spike in seven days and 50 percent higher than prices before the Iran war began.
How much is the Iran war adding to fuel costs?
The 50 percent increase puts gasoline at its highest national average since mid-2022. For context: a $4.48 gallon means an owner-operator running a gas-powered Sprinter or a small fleet deadheading 200 miles to pick up a load now pays $90 in fuel for that repositioning move, versus $60 at pre-conflict prices. The math compounds on every bobtail, every personal-use mile, and every light-duty support vehicle a carrier runs.
Diesel typically tracks gasoline with a lag of days to weeks, and the Iran conflict has disrupted crude supply from the Persian Gulf — the source of roughly 20 percent of global oil exports. While AAA's May 5 snapshot covers gasoline only, diesel surcharges and pump prices have historically followed crude moves within a two-week window. Small fleets that locked fuel cards or negotiated fixed fuel surcharges before the spike now face a widening gap between what they pay at the pump and what they recover on the settlement sheet.
What the 31-cent weekly jump means for settlement math
A 31-cent-per-gallon move in a single week is the kind of volatility that breaks budgets built on stable fuel assumptions. An owner-operator running 2,500 miles a week in a Class 8 tractor averaging 6.5 MPG burns roughly 385 gallons. If diesel follows gasoline's trajectory — and it has in every prior Middle East supply shock — that same operator is looking at an extra $119 per week in fuel cost with no corresponding rate increase to offset it. Multiply across a 10-truck fleet and the weekly delta is $1,190 before accounting for any deadhead or personal miles.
Spot rates have not moved in tandem. Contract rates remain flat or down in most lanes, and fuel surcharges tied to the Department of Energy's weekly diesel index lag the pump by a week. The result: carriers eat the first week of any spike, and if prices stabilize quickly, they never recover the gap.
Why this price level sticks
Gasoline at $4.48 is not a one-day anomaly. The 50 percent increase since the conflict began reflects sustained crude supply disruption, not a temporary refinery outage or seasonal demand blip. Iran and its proxies control or threaten shipping chokepoints that move 21 million barrels of oil per day through the Strait of Hormuz. Any closure or sustained military action in that corridor keeps crude prices elevated, and refined products follow.
The Jones Act waiver extended in late April allows foreign-flagged tankers to move fuel between US ports, which may ease regional price disparities on the coasts, but it does not add crude supply or refining capacity. The waiver helps logistics; it does not fix the upstream supply shock driving the 50 percent increase.
For small fleets, the operational takeaway is blunt: fuel is now a larger line item than it was 90 days ago, and nothing in the current geopolitical or market structure suggests a return to pre-conflict pricing in the next quarter. Carriers that can renegotiate fuel surcharges or shift to higher-paying lanes that cover the delta will survive the margin squeeze. Those running on thin contract rates with no fuel escalator are already underwater.
