What sets the price of a gallon in the United States and elsewhere, and why record American oil production does not buy a local discount.
By Jason Fite
North Port, Florida · October 2, 2026
On October 1, AAA put the U.S. average for regular gasoline at $4.40 a gallon, down a few cents from a record September. Diesel sat at $6.37. A year earlier regular was near $3.13. Autumn usually cheapens the pump. This year it did not.
The United States produced about 13.6 million barrels of crude a day in 2025, more than any country has produced in a year. Refiners here make nearly all the gasoline sold at American stations. Neither fact sets a private American price. Crude is bid on a world market. A barrel from Midland and a barrel from Ras Tanura clear against the same buyers.1
A gallon is a stacked bill. The largest line is that world price. The next lines are local: refining, the last miles of delivery, the fuel formula the air rules require this season, and the tax. A legislature can change the last line by tens of cents. It cannot rewrite the first.
Four lines on the receipt
Each month the Energy Information Administration splits the national average into crude oil, refining, distribution and marketing, and taxes. Crude is what refiners actually paid that month, not the day’s futures print. Refining is the gap between that cost and the spot price of gasoline leaving the plant. Taxes are the federal-plus-state average. Distribution and marketing is whatever is left.2
The leftover jitters because retail lags the spot market. When crude jumps, the crude share swells until stations catch up. When crude falls, the leftover can look fat for weeks. The table is a lag chart, not a verdict.
In May 2026, with regular at $4.479, EIA assigned the gallon this way:
Crude oil: 51.9% — 232.5 cents ($2.33) per gallon.
Refining: 21.7% — 97.2 cents ($0.97) per gallon.
Distribution and marketing: 14.8% — 66.3 cents ($0.66) per gallon.
Taxes: 11.5% — 51.5 cents ($0.52) per gallon.
EIA Gasoline Pump Components History, May 2026. Cents are the published shares times $4.479.3
In February 2026, before the shock had fully reached the sign, regular averaged $2.908. Crude was still about 52 percent. Taxes were 17.8 percent. The tax in cents barely moved. Its share of the sticker fell because the sticker rose. A flat excise works that way.
June 2008 is the useful comparison. Regular was $4.054. Crude was 74.8 percent of that gallon. Refining was 8.5 percent. That year was a crude spike refiners passed through. 2026 is a crude spike and a refining-margin spike at once. Similar pump price. Different recipe.
Diesel shows the refining line more clearly. In May, diesel averaged $5.60. Crude was 41.5 percent, refining 25.3 percent, distribution and marketing 22.5 percent, taxes 10.7 percent. Distillate was tight before February and tighter after. A $6.37 diesel gallon does not stay at the truck stop. It shows up in freight, food, and anything that arrived by highway.4
The tax is the line a statehouse can write
The federal gasoline tax is 18.4 cents a gallon: 18.3 cents of excise and a tenth of a cent for leaking tanks. It has not changed since 1993. EIA’s January 2026 snapshot put average state taxes and fees at 33.27 cents. Combined, about 52 cents. That matches the May tax line almost to the penny. City and county levies sit on top in some places and are not in that average.5
State rates are why two American gallons can differ by two dollars before crude enters the argument. California’s state fuel taxes and fees run in the low-to-mid 70 cents. Alaska’s state tax is about 9 cents. Texas is 20. On September 29, AAA had California regular near $6.38 and Indiana near $3.86, with the national average near $4.48. Taxes do not explain the whole California gap. The state also requires a boutique formula, and its refining system is isolated from the Gulf. They do explain a large, countable piece, and they explain why “the national average” is a statistic, not a price anyone pays.
One market
The well does not set the pump. Producers sell into a market that clears globally. A Gulf Coast refiner can buy domestic crude or imported crude. The acquisition cost in EIA’s table is an average of both. When a chokepoint that usually carries about a fifth of seaborne oil is disrupted, every barrel is re-bid, including barrels that never left Texas.
Retail analysts use a rough rule: a $1 move in crude tends to move the pump by about 2.4 to 2.5 cents, once the move has worked through. Oil has to be refined, scheduled onto a pipeline or a barge, priced at a rack, and posted on a sign. Stations price off the next load, not last week’s invoice. A spike shows up in days. A drop can take months to finish arriving.
Volume and price are different facts. The country can be a large producer and a large exporter of products and still take the world price. Oil is invoiced in dollars, so anyone buying in euros, pounds, or yen is also making a currency trade. A stronger dollar raises their pump even if Brent is flat.
The 2026 shock, counted
On February 28, the United States and Israel began strikes on Iran. The Strait of Hormuz, which in ordinary years carries roughly 20 percent of traded oil, became a war zone. Pre-war crude exports from the Gulf, through the strait and around it, ran near 19 million barrels a day. Flows collapsed, then partly rebuilt on shuttle tankers, escorted convoys, and bypass pipelines. By late September, tracker estimates put traffic somewhere between about 65 and 80 percent of pre-war levels, depending on the firm and on whether the count included products. The spread is the finding. No one has a single meter on a contested strait.6
Inventories took the hit. The International Energy Agency put observed global stocks about 507 million barrels below the pre-war level in one September tally. Other counts sit near half a billion. A McKinsey reconstruction of the first-round gap assigned about 35 percent to pipelines and new supply, 20 percent to inventory draws, and 45 percent to lower consumption, much of it in China and the Middle East.7
Those buffers are spent or thin. The Strategic Petroleum Reserve, already drawn down earlier in the decade, was reported near 285 to 300 million barrels by late summer, the lowest since the early 1980s. A March release by 32 countries put more than 400 million barrels into the market. China cut imports and released both declared and previously undeclared stocks. Those moves kept Brent out of the $150 and $200 scenarios that circulated in March. They did not keep it at $65. EIA’s September outlook had Brent averaging about $91 for 2026, after $69 in 2025, with inventories still falling into year-end. On October 1, Brent’s spot close was $114.82 and WTI was $99.77.8
Most oil-price swings in peacetime are demand and expectation stories. Lutz Kilian’s 2009 paper is the standard citation. 2026 is the exception the textbooks keep around: millions of barrels a day left the traded market.
Products did not move in lockstep with crude, which is why the year feels more expensive than the crude chart alone. Diesel and jet were tight before February. Russian product flows were already bent by the war in Ukraine. Chinese fuel exports were held back to protect the home market. U.S. distillate stocks were forecast to drop under 100 million barrels. The margin between a barrel and the fuels made from it widened. That is the 22 percent refining share on the May gasoline gallon, and the 25 percent share on the May diesel gallon.
Up fast, down slow
Gasoline rises faster than it falls. After the strikes, WTI ran from the high $60s toward peaks above $110. Regular ran from $2.98 on the eve of the strikes to a weekly high near $4.50 in May. When a stretch of talks in June pulled crude back toward the high $60s and low $70s, the pump did not retrace the same percentage. A St. Louis Fed note on the episode estimated that even if oil had returned to pre-war levels by mid-July and stayed there, retail would have taken on the order of six months to fall within 25 cents of its old level.9
The lag is how the stack works. Crude trades daily. Refining runs on a weekly and monthly clock. Rack prices are set off the next load. A station that cuts too early sells fuel bought at the old high at a loss. A station that cuts too late loses cars to the corner across the street.
Season adds friction. Summer-blend gasoline, made to limit evaporation, costs more than winter blend. The spring switch tightens supply as driving rises. The fall switch usually loosens it. A shock that lands across that calendar writes the seasonal bump on top of the war bump. Boutique fuels isolate markets. A gallon that cannot legally move from Houston to Los Angeles cannot close the gap between them.
Three regimes, one barrel
Convert pump prices to dollars per U.S. gallon and the world sorts into three groups.
The first is subsidy. Venezuela, Iran, and Libya have sold gasoline in 2026 for cents a gallon, in some snapshots under 15 cents. Kuwait, Saudi Arabia, and Iraq sell well below the export value. The low sticker is a budget choice. The state oil company sells at home below what the barrel would fetch abroad. The difference is paid by the treasury, by foregone exports, or by both. When those budgets tighten, the sticker jumps and the street notices.10
The second is light tax. Late September: U.S. regular about $4.45 to $4.48. Canada, even with a temporary federal excise suspension, was near C$1.81 a litre. Japan held regular near ¥170 a litre under a subsidy, roughly $4.30 to $4.50 a gallon. India sat near ₹108 a litre, about $4.40 a gallon, with a large state-tax component that does not move when Brent moves. These markets feel the crude shock. They do not double it.11
The third is high excise plus value-added tax. Britain’s fuel duty is a flat 52.95 pence a litre, at $60 Brent or $120. On September 28 the RAC average for petrol was 174.13 pence a litre, about $8.30 a gallon, and diesel set a record at 199.18 pence. Germany, France, Italy, and the Netherlands clustered around €2.00 to €2.45 a litre in late September, roughly $8 to $10 a gallon. Hong Kong petrol near HK$34.70 a litre converts to more than $15 a gallon. In those markets tax is often half to two-thirds of the sticker. A 60 percent rise in crude lifts the pump by much less, because half the price was never crude. A fall in crude does the same thing in reverse.12
Two countries can import the same barrel, run it through similar plants, and post stickers that differ by a factor of two or ten. The gap is the rate the state charges for the road, the rate at which it hides the cost from voters, and the exchange rate against the dollar.
Household burden does not track the sticker. A $4.40 gallon in a country where people drive 12,000 miles a year in a 25-mile-per-gallon car is a different monthly bill than an $8 gallon in a country with short trips and a train. Both complaints can be true.
What moves the sticker
Ranked, the list is short.
The world crude price. In a shock month it is half or more of a U.S. gallon. In a quiet month it is still the largest line. A production record does not repeal it.
Refining and the fuel formula. Capacity, seasonal rules, and regional isolation decide whether a $90 barrel becomes a $3.80 gallon or a $4.80 gallon. The fat refining share in 2026 is this line.
Taxes. In the United States they are a written number that barely moves when crude doubles. In much of Europe they are the majority of the sticker. In several producing countries they are negative. A tax holiday can take 20 to 70 cents off a state average for as long as the treasury will stand it. It cannot take $2 off a missing chokepoint.
Delivery. Pipelines, the Jones Act on cargoes between U.S. ports, trucking distance, and the cost of keeping a station open. Hawaii and Alaska pay a logistics premium no tax cut erases. A temporary Jones Act waiver can move barrels toward a short coast. It cannot rebuild a closed refinery.
Stocks. A reserve release buys time. It does not replace a missing two million barrels a day for two years. Once the tanks are low, the next shock has a shorter cushion. That is the fact under the 2026 reserve number.
Demand. Efficiency, recession, and substitution into electricity change how many gallons a population buys. They change the price only by changing the bid, and they are slow.
A party label does not appear on the receipt. Administrations can release reserves, waive shipping rules, lean on producers, and suspend taxes. Measured effects of those tools are tens of cents and weeks to months. The dollar-plus move of a closed strait is larger than any of them.
If the question is why the national average is more than a dollar above February, the answer is crude plus refining margins under a supply shock. If the question is why California runs about $2 above Texas on the same Tuesday, the answer is taxes, fuel spec, and a regional refining island. If the question is why a U.S. gallon of petrol in Germany costs about twice a gallon in Houston, the answer is excise and VAT. If the question is why last year’s record U.S. output did not make the driver whole, the answer is that the output was sold into a world market that was missing a chokepoint.
As of October 2, flows through Hormuz are better than in the spring and not what they were in January. Inventories are thin. Diesel is tighter than gasoline. EIA’s September forecast had Brent easing in 2027 if production rebuilds and tanks refill. A forecast is not a delivery. The October 1 spot prints were still above $100.
