The U.S. Vitality Data Administration expects nationwide retail gasoline costs to average near US$4.30 a gallon for April 2026 – the very best month-to-month common of the yr. The political response has been acquainted. Georgia has suspended its state gas tax, different states are weighing their very own tax holidays, and the White Home has issued a temporary waiver of a law known as the Jones Act in hopes of shifting extra home gas to East Coast ports.
As an energy economist, I’m usually requested about what contributes to fuel costs and what completely different insurance policies can do to have an effect on them.
The worth of a retail gallon of fuel is the sum of 4 issues: the price of crude oil, refining, distribution and advertising, and taxes.
In nationwide figures from January 2026, crude oil accounted for about 51% of the pump price, refining roughly 20%, distribution and advertising about 11% and taxes about 18%. That blend shifts with situations: When crude oil costs spike, that may drive greater than 60% of the value; when the value drops, taxes and logistics are bigger shares of the fee.
Crude oil is the most important ingredient
As a result of the value of crude oil is the most important aspect, many of the worth on the pump is derived from the worldwide oil market.
Often, big swings in crude prices come primarily from shifts in international demand and expectations – not from provide disruptions, in accordance with extensively cited analysis in 2009 by the economist Lutz Kilian.
However what is going on in early 2026 with the warfare in Iran is without doubt one of the exceptions: a classic supply shock. Severe disruptions to shipping through the Strait of Hormuz and assaults on Center East oil infrastructure have taken hundreds of thousands of barrels a break day the worldwide market.
Most drivers typically can’t shortly scale back how a lot they drive or how a lot fuel they use when costs rise, so gasoline demand doesn’t change much in the short run. Which means a leap in crude prices tends to end in individuals paying extra reasonably than driving much less.
Refining, laws and the California puzzle
Refining turns crude into gasoline at industrial scale. The U.S. doesn’t have a single gasoline market, although. Roughly a quarter of U.S. gasoline is a cleaner-burning mix of petroleum-derived chemical compounds known as “reformulated gasoline,” which is required in city areas throughout 17 states and the District of Columbia to cut back smog.
California makes use of an even stricter formulation that few out-of-state refineries make. California can also be geographically remoted: No pipelines deliver gasoline in from different U.S. refining areas.
California’s gasoline costs have long term above the nationwide common, defined partially by higher state taxes and stricter environmental guidelines. However since a refinery fire in Torrance, California, in 2015 lowered manufacturing capability, the state’s costs have been about 20 to 30 cents a gallon larger than what these components would point out.
Vitality economist and College of California, Berkeley, professor Severin Borenstein has known as this the “mystery gasoline surcharge” and attributes it to the truth that there isn’t as a lot competitors between refineries or fuel stations in California as in different states. California’s personal Division of Petroleum Market Oversight says the surcharge price the state’s drivers about $59 billion from 2015 to 2024. It’s not precisely clear who’s getting that cash, but it surely may very well be gas stations themselves or refineries, by way of complicated contracts with fuel stations.

Getting the fuel into your automobile
The distribution and advertising class covers the prices of every little thing concerned in getting the gasoline from the refinery gate to your tank.
Gasoline strikes by pipeline, ship, rail and truck to wholesale terminals, after which by native supply truck to service stations.
On the retailer’s finish, the important thing components are station lease and labor, the fee to purchase gasoline in bulk to have the ability to promote it, credit card fees of as a lot as 6 to 10 cents a gallon at present costs, and franchise charges paid to the nationwide model, resembling Sunoco or ExxonMobil, for permission to place their branding on the fuel station.
Most fuel station operators internet only a few cents per gallon on gas itself – which is why many fuel stations are actually comfort shops with pumps out entrance. Borenstein and a few of his collaborators have additionally documented that retail gas prices rise quickly when wholesale prices climb however fall slowly when wholesale prices drop.
The query of fuel tax holidays
The federal authorities expenses a tax on gas, of 18.4 cents a gallon for gasoline and 24.3 cents a gallon for diesel. States cost their very own taxes, starting from 70.9 cents a gallon for gas in California to eight.95 cents in Alaska.
When fuel costs rise, many politicians begin speaking about quickly suspending their state’s fuel tax. That does scale back costs, however not as a lot as politicians – or shoppers – may hope. Analysis on previous fuel tax holidays has discovered that buyers get about 79% of the reduction in fuel taxes. Which means oil corporations and gas retailers maintain about one-fifth of the tax reduce for themselves reasonably than passing that financial savings to the general public.
Fuel tax holidays additionally scale back funding for what the taxes are designed to pay for, sometimes roads and bridges. That pushes highway and bridge repairs prices onto future drivers and normal taxpayers.
There may be a further downside, too: Taxes on gasoline are alleged to cost drivers for among the costs their driving imposes on everyone else – carbon emissions, native air air pollution, congestion and crashes. However Borenstein has discovered that U.S. gas tax ranges are already far below the true cost to society. Eradicating the tax on drivers successfully raises the prices for everybody else.

The Jones Act: A small quantity that provides up
The 1920 Jones Act is a federal legislation that requires cargo shifting between U.S. ports to journey on vessels constructed and registered within the U.S., owned by U.S. residents, and crewed primarily by U.S. residents and everlasting residents. Of the world’s 7,500 oil tankers, only 54 meet this requirement. Only 43 of these can transport refined fuels resembling gasoline.
So, regardless of important refining capability on the Gulf Coast, some U.S. gasoline is exported abroad even because the Northeast imports gas, partially reflecting the relatively high cost of moving fuel between U.S. ports.
Economists Ryan Kellogg and Wealthy Sweeney estimate that the legislation raises East Coast gasoline prices by about a penny and a half per gallon on common, costing drivers roughly $770 million a yr. In mild of the warfare’s impact on fuel costs, the Trump administration has temporarily suspended the Jones Act requirements – an motion extra generally taken when hurricanes knock out Gulf Coast refineries and pipeline networks.
What strikes the quantity
The results of all these components is that the value that drivers see on the pump largely displays the worldwide worth of crude, plus a stack of home prices, solely a few of that are inefficient.
Tax holidays give a partial, short-lived rebate. Jones Act waivers trim pennies, although everlasting repeal could trigger extra basic adjustments, resembling reduced rail and truck transport of all goods, which might decrease prices, emissions and infrastructure injury related to cargo transportation. Harmonizing gas blends throughout states and seasons could decrease costs considerably, however possible on the expense of elevated emissions.
In the end, one of the best safety in opposition to oil worth shocks is a extra environment friendly gas-burning automobile, or one that doesn’t burn gasoline in any respect. Within the meantime, one of the best I can supply as an economist is readability about what that $4.30 truly buys.
