$4 Gas Looms for First Time in Three Years

• The national average for a gallon of regular unleaded gasoline is closing in on $4, a level last seen in 2022, with economists warning of a drag on GDP growth, rising inflation, and a disproportionate hit on lower-income households.
• Oil prices have risen more than $30 a barrel from pre-war levels, and pump prices are already running 18 cents higher than that oil increase alone would explain, pointing to broader inflationary pressure building through the economy.
• Federal Reserve tools are limited in addressing the threat, with one economist warning that “uncertainty has just been unprecedently high for a very long time, and that is its own tax on the economy.”

What $4 Gas Means for American Households and the Economy

The national average price for a gallon of regular unleaded gasoline is closing in on $4, a level last reached in 2022 that carries real stress for household budgets, inflation expectations, and the wider US economy.

The figure is not uniform. California, Washington state, and Hawaii already sit above $5 a gallon. Some lower cost-of-living states remain under $3.50. Wherever the pump price lands, the direction is the same, and crossing $4 carries equal symbolic and mathematical significance.

“This is worrisome, especially for those who have the least ability to weather the storm,” said Diane Swonk, chief economist at KPMG.

The Numbers Behind the $4 Gas Threshold

Joe Brusuelas, chief economist at RSM US, laid out what each $10 increase in oil prices means for the broader economy: a 0.1 percentage point drag on real GDP growth, a 0.2 percentage point rise in inflation, a 24-cent increase at the pump, and a $450 annual hit to the average household.

Oil prices have risen more than $30 a barrel from pre-war levels, against a pre-war average of $2.98 a gallon. That translates to roughly a 0.3 percentage point reduction in GDP growth, against a reading of 0.7% at the end of last year. The effect is modest in isolation but accumulates over time, Brusuelas said.

The US is a $30 trillion economy, a scale that absorbs shocks better than most.

“However, even a $30 trillion beast has its pain points,” he added.

The point at which economists begin discussing demand destruction, where prices grow high enough that consumers cut behavior and spending, sits at oil above $125 a barrel, gas above $4.25 a gallon, and inflation above 4%. Some consumers are already adjusting, taking fewer trips and pulling back on discretionary spending.

Inflation Is Running Hotter Than the Oil Price Rise Alone Explains

The gap between what oil prices imply for pump costs and what drivers are actually paying tells a wider story. With oil up $30 from pre-war levels, standard estimates pointed to a 75-cent rise at the pump. The actual increase was 93 cents.

“So, what that tells us, is the risks on inflation are a little bit higher,” Brusuelas said.

US consumer prices were rising at an annual rate of 2.4% in February, ahead of the war. That rate could climb to 3.5% when March data is released and push above 4% in April, Brusuelas said. The gap beyond what oil accounts for reflects broader energy price increases in diesel and jet fuel, as well as war-affected inputs such as fertilizer. Those secondary and tertiary effects will work through to American households in the months ahead, regardless of whether the conflict ends soon.

“The American public is going to bear the burden of adjustment of this,” Brusuelas said, adding, “something that’s going on now will still be impacting them come December.”

The comparison to 2022, the last time the $4 level was crossed, offers limited reassurance. That was a different economic environment.

“Back in 2022, the unemployment rate was plummeting, we were generating hundreds of thousands of jobs a month, and a majority of Americans were believing we were in a recession,” said Swonk.

“Now, we’re on the other side of that where we’re generating hardly any jobs in a month – though you don’t need to generate many jobs to hold the unemployment rate steady – but it’s a higher unemployment rate than it was back then.”

Pay growth has slowed, labor market opportunities have narrowed, and five years of sustained inflation have compounded the strain on household finances. Rising debt levels are becoming difficult to manage, most acutely for lower-income Americans.

“The level of prices is already too high for too many,” Swonk said.

The Federal Reserve faces the prospect of a stagflationary environment, an economic slowdown running alongside rising prices, which limits what interest rate adjustments can achieve. Rate moves can dampen demand but cannot address supply-side disruptions rooted in geopolitical conflict.

“Uncertainty has just been unprecedently high for a very long time, and that is its own tax on the economy,” Swonk said. “I don’t know how you eliminate uncertainty, unless there’s an abrupt end to the war in the Middle East. Interest rates alone can’t stimulate demand for workers.”
