Why Do Gas Prices Rise So Fast but Fall So Slowly

Why do gas prices rise so fast but fall so slowly? If you have ever watched the sign at your local station jump 30 cents overnight, then creep down a penny at a time for weeks, you are not imagining it. Drivers across the United States see the same pattern after almost every oil price spike, and it is frustrating precisely because it feels personal, as if someone decided you should pay more for longer.

The truth is less sinister than a backroom deal, but no less annoying. Economists have studied this pattern for decades, the Federal Trade Commission has investigated it more than once, and the forces behind it are a mix of thin margins, slow supply chains, and plain human behavior, including yours. Once you see how the pieces fit together, the pump price starts to make a kind of sense, even if you still do not like it.

The pattern has a name: rockets and feathers

Back in 1991, British economist Robert Bacon published research showing that retail petrol prices shot up quickly when wholesale costs rose, but floated down gently when costs fell. He called it rockets and feathers, and the name stuck because it fits so well. Prices rise like a rocket and fall like a feather.

Later work, including research by UC Berkeley economist Severin Borenstein and his colleagues, confirmed the same asymmetry in the United States. According to Federal Trade Commission research cited in recent coverage, retail gas prices rise roughly four times faster than they fall. That is not a rounding error. It is a real, measurable gap, and it shows up in country after country, from the United Kingdom and Germany to France, South Korea, and Colombia.

So the question is not whether the pattern exists. It does. The question is why it keeps happening, and the answer turns out to be several smaller reasons stacked on top of each other.

What a gallon of gas actually costs you

Before blaming any one player, it helps to see what you are paying for. According to the US Energy Information Administration (EIA), crude oil is the biggest single ingredient, usually around half the retail price of a gallon, though the exact share moves with the market. Refining crude into gasoline adds the next chunk, then distribution and marketing, the cost of moving fuel to terminals and running stations.

Then there are taxes, and these never move with oil prices. Federal tax adds 18.4 cents per gallon, and state taxes and fees add roughly 33.55 cents on average, though your state may be higher or lower. Add it up and a large part of every gallon is fixed cost before anyone talks about profit. That matters, because it means a 10 dollar fall in the price of a barrel of oil never translates into a 10 dollar fall at the pump. The EIA uses a rough rule of thumb: a gallon of gasoline moves about 2.4 cents for every 1 dollar move in a barrel of oil, and even that relationship is not exact.

Keep that in mind as we go through the five forces below. None of them alone explains the whole lag. Together, they do.

Stations price the next tank, not the last one

Here is the single most important idea in this whole article. When wholesale prices rise, a station owner does not price the fuel already sitting in the underground tanks. She prices the fuel she will have to buy next.

Think about it from behind the counter. If your supplier tells you the next delivery will cost 40 cents a gallon more, and you keep selling today at the old price, you will not have enough cash to refill the tanks when they run dry. So you raise the price now, even though the fuel in the ground was bought cheaper last week. Economists call this replacement cost pricing, and it is why prices jump before the expensive fuel ever arrives.

On the way down, the logic flips. The tanks are full of fuel bought at the higher price. Cutting the sign price immediately would mean selling that fuel at a loss, or at least at a much thinner margin. So the owner waits until the cheaper delivery actually arrives, then starts lowering the price. As Virginia Tech economist Jadrian Wooten put it in a 2026 explainer, station owners care about what it will cost to fill the tanks back up, not what they paid last week. That one habit explains a big part of the asymmetry.

Your station barely makes money on gas

This surprises most drivers. The typical station makes only about 3 to 7 cents of net profit per gallon of fuel, a margin under 2 percent. Compare that with a grocery store or a bank and you start to see why station owners are so jumpy about costs.

Most stations actually make their real money inside the store, on coffee, snacks, and convenience items, not at the pump. Fuel is the thing that gets you to stop. That is why a station cannot absorb a wholesale spike for even a day or two: selling at a loss for a weekend could wipe out weeks of fuel profit. Raising prices fast is not greed in this case. It is survival.

But the same thin margin explains the slow fall, too. When wholesale costs drop, the station finally has a chance to rebuild the margin it lost during the spike. Every extra day at the higher price is a day of slightly better profit. There is no rule forcing the owner to pass the saving on the same day, so many do not.

You stop shopping around when prices fall

This one is on us, the drivers, and the FTC has flagged it as a leading explanation. When prices surge, you notice. You check GasBuddy, you drive an extra mile for the cheaper station, you compare every sign on the block. That shopping pressure forces stations to compete hard on the way up, because a station that lags behind gets flooded with cars it cannot profitably serve, and a station that jumps ahead loses customers.

When prices start falling, though, most of us relax. The sign says 3.80 instead of 4.10 and it feels like a relief, so we pull into the most convenient station and stop comparing. With fewer drivers hunting for bargains, stations feel less pressure to cut quickly. Economists call this asymmetric search behavior. In plain English, it means our attention is part of the pricing system, and when our attention fades, so does the competition.

The practical lesson is simple and we will come back to it: keep comparing prices during a price fall, not just during a spike. That is when your comparison shopping does the most good.

The supply chain only moves one way, and slowly

Crude oil does not turn into gasoline the moment a price changes on a trading screen. It has to be refined, shipped to regional terminals, loaded onto tanker trucks, and delivered to individual stations. Each step takes time, and each step holds inventory bought at an earlier price.

When oil jumps, the price signal races forward anyway, because futures contracts adjust in real time and everyone along the chain wants to protect their margin. Refiners reprice, wholesalers reprice, stations reprice. When oil falls, there is no matching urgency. The refiner already bought crude at the old price, the wholesaler holds stock, the station holds a full tank. Nobody wants to be the one to sell expensive inventory cheaply.

Disruptions make this worse. When a hurricane shuts Gulf Coast refineries, as Hurricane Katrina did in 2005, or a conflict chokes supply, refiners may raise prices to discourage consumption and stretch available stock. The St. Louis Fed documented a modern version of this in 2026: after the US conflict with Iran began in late February, West Texas Intermediate crude jumped from 66.96 dollars on February 27 to 90.77 dollars by March 6, and average US gasoline rose from 2.94 dollars to over 3.50 dollars within two weeks. When oil later fell back from 99.76 dollars on June 3 to 69.60 dollars by July 6, gasoline was still hovering around 3.78 dollars. A Fed model suggested it could take about six months for pump prices to get within 25 cents of their pre-conflict level, even if oil stayed flat. That is the supply chain lag, measured in months.

Nobody wants to cut first

Gas stations sell a nearly identical product, often directly across the street from each other, with prices posted on giant signs for everyone to see. That setup creates a strange competitive game.

On the way up, no station wants to be the last to raise its price. If your competitor raises prices and you do not, every driver on the road pulls into your station and you sell out your tank at a money-losing price within hours. So stations race each other upward. It is self preservation.

On the way down, the game reverses. If you cut first, you attract more customers, but at a thinner margin, while your competitor across the street keeps the higher price a little longer and pockets more per gallon. There is no reward for being the brave first cutter, and there is a quiet penalty for it. So everyone waits for someone else to move, and the whole street drifts down slowly together. Researchers sometimes describe this as tacit coordination, not a secret agreement, just rivals watching the same signs and making the same cautious choice.

A tale of two weeks: the same oil move, two very different pump stories

It helps to walk through a concrete example, because the asymmetry is easier to feel than to describe in theory. Imagine crude oil jumps 10 dollars a barrel on a Monday after a supply scare.

By Tuesday, futures traders have repriced, refiners have raised wholesale prices, and your local station owner, knowing the next tanker will cost more, raises the sign by 20 cents. By Friday, the whole street has followed, and you are paying noticeably more, even though the fuel in the ground was refined weeks ago.

Now imagine the reverse: crude falls 10 dollars a barrel on a Monday after a ceasefire. Your station still holds a tank bought at the higher price, so the owner trims the sign by 2 cents, just enough to look responsive. The station across the street trims by 1 cent. Nobody is in a rush, because nobody is losing money by waiting, and most drivers have stopped checking prices anyway. Two weeks later, crude is down 10 dollars but your pump price is down maybe 8 or 10 cents, not the 24 cents the EIA rule of thumb might suggest, and the rest of the saving arrives in pennies over the following month.

That is rockets and feathers in real life: fast on fear, slow on relief.

When the pattern breaks

The pattern is strong, but it is not a law of nature, and knowing the exceptions tells you a lot about how it works. The most common exception is a new competitor. When a Costco, Sam’s Club, or Walmart fuel station opens nearby, or when two stations start a genuine price war, prices can fall fast, because someone finally has a reason to cut first: winning volume.

Local competition matters more than national averages suggest. A town with five stations on one busy road will usually see faster price drops than a rural stretch with a single station and no alternative for 20 miles. That is also why your town can pay 40 cents more than the next town over: different taxes, different delivery costs, different levels of competition, and sometimes just a different wholesale terminal.

Refinery outages can also break the pattern in the other direction. If crude falls but a major refinery goes offline, wholesale gasoline can stay expensive even while oil gets cheaper, and drivers rightly feel confused. The pump price follows gasoline, not crude directly, and the two can separate for weeks.

What you can actually do about it

You cannot fix the oil market from your car, but you can keep more money in your pocket while the feathers drift down. The single best habit is to keep comparing prices during a price fall, when most drivers stop. Apps like GasBuddy, plus the price maps in apps from AAA and many navigation tools, make this a 30 second check before you fill up.

A few more moves that genuinely help: fill up on the cheapest day of the week in your area, which in many US cities falls midweek rather than on weekends, though the pattern varies by city, so watch your local stations for a few weeks and note it. Use loyalty programs and grocery fuel points, which often save 10 to 30 cents a gallon regardless of what crude does. Keep your tires properly inflated and your driving smooth, since aggressive acceleration burns fuel faster than any price move costs you. And if you have a membership club station nearby, compare its price with the street: the saving is often 20 cents or more per gallon, which adds up to hundreds of dollars a year for a daily commuter.

None of this changes the system. But it does change who captures the lag: you, or the station across the street.

Frequently asked questions

Is it illegal for gas stations to keep prices high when oil falls?

Not by itself. Charging a high price is legal. What is illegal is collusion, meaning competitors secretly agreeing to fix prices, and the FTC does investigate suspected cases. Slow price falls alone are not proof of collusion, because inventory costs, thin margins, and consumer search behavior can produce the same pattern without any agreement.

Why does my town pay more than the next town over?

State and local taxes differ, delivery distances differ, and competition differs. A town served by a distant terminal, or with only one or two stations, will usually pay more than a town with a busy corridor of competing stations, even when both buy the same crude.

Do gas prices ever fall as fast as they rise?

Sometimes, usually when competition forces it. A price war, a new discount station, or a sharp demand collapse can push prices down quickly. But in an ordinary market with ordinary competition, falls are slower than rises, and that is the normal pattern economists have measured for decades.

Will electric cars end rockets and feathers?

For drivers who switch, yes, in the sense that they stop buying gasoline altogether. For everyone else, the pattern will last as long as gasoline is sold through local stations with thin margins and slow-moving inventory. The long run answer is a different fuel, not a different pricing rule.

Conclusion

Why do gas prices rise so fast but fall so slowly? Because stations price the fuel they still have to buy, not the fuel they already own. Because they make almost nothing per gallon and cannot afford to absorb a spike. Because drivers shop hard when prices rise and relax when they fall. Because the supply chain moves slowly in one direction. And because no station wants to be the first to cut.

None of that makes the wait at the pump feel fair. But understanding it does give you one real advantage: you know when the system is working against you, and you know the one habit that pushes back, which is to keep comparing prices even when the pressure feels off. The feathers fall faster when drivers are watching.
