Why Gas Prices Rise Fast, and Fall Slowly at the Pump

Why gas prices rise fast, and fall slowly at the pump

The pump price is more than crude oil

Gasoline feels like it should move in lockstep with oil, but the price on the sign is built from several parts. The U.S. Energy Information Administration says retail gasoline includes crude oil, taxes, refining costs and profits, plus distribution and marketing costs. That means a crude shock is only one piece of the bill that drivers see.

Taxes matter, too. The federal gasoline tax is 18.40 cents per gallon, and as of January 2026 state taxes and fees averaged 33.55 cents per gallon. Those charges do not explain every swing at the pump, but they set a floor under the price and help show why gasoline rarely behaves like a simple commodity ticker.

The EIA also emphasizes that retail pump prices reflect the profits and losses of refiners, marketers, distributors and retail station owners. In other words, the local station is not just passing through a number from global oil markets. It is balancing wholesale replacement costs, competition, taxes and the margin it needs to stay open.

Why prices can jump so quickly

The sharp rises that frustrate drivers usually start with crude oil, which the American Petroleum Institute notes is traded in global markets. That means gasoline prices respond to worldwide supply and demand, not just domestic production. Regional fuel rules, transportation costs and competition at the station level also shape what you pay in your town, whether you are filling up on the East Coast, West Coast, in California or Alaska.

Retailers often do not immediately pass along the full increase when oil prices rise. NACS says station owners tend to hold back their margins to stay price-competitive, because price is the biggest factor for drivers choosing where to buy gas. In a 2025 NACS Consumer Fuels Survey, 72% of drivers said price was the most important factor, 16% pointed to location and 12% to brand. The same survey found that 69% would drive five minutes out of their way to save 5 cents a gallon.

That is why gas can move fast. If one station keeps prices too high for even a short time, drivers can leave. NACS says retailers often price fuel using a replacement-cost model, meaning they price the next shipment at the new higher wholesale cost instead of the cheaper fuel already sitting in storage. At larger stores that receive multiple deliveries a day, that can trigger a quick jump on the sign even before the old inventory is gone.

NACS has pointed to cases where retail gasoline prices jumped 20 cents per gallon over two days. That kind of move is not usually about a station suddenly getting greedy; it is often a reaction to a higher wholesale market that retailers do not want to underprice as their next tanker arrives.

Why prices drift down more slowly

The reverse is where the frustration builds. Stanford researchers Neale Mahoney and Ryan Cummings describe the pattern as “rockets and feathers”: gasoline prices shoot up quickly when oil rises, then float down slowly when oil falls. The reason is partly arithmetic and partly psychology. Once a station has repriced to a higher replacement cost, it has little incentive to cut immediately if competing stations are still holding firm.

That slow descent is not unique to gas, but gasoline is especially painful because it is one of the least discretionary items in household budgets. Stanford’s analysis says fuel spikes are regressive because lower-income households spend a larger share of their budgets on gasoline. It also says gas prices can shape inflation expectations and even influence Federal Reserve decisions, which is one reason economists watch the pump as a signal, not just a household expense.

The Stanford team’s latest war-related scenario, tied to risk around the Strait of Hormuz, projected gas prices could peak above $4.25 per gallon in May and households could pay $857 more for gasoline over the rest of the year. That is the kind of shock that shows how quickly a supply threat can feed through to everyday costs.

What normal market behavior looks like

A slow decline does not automatically mean manipulation. The EIA says higher U.S. oil production in recent years has helped slow the rise in oil and gasoline prices overall, but gasoline demand usually increases in the summer, which pushes prices back up just when many drivers hope for relief. In May 2024, the EIA forecast U.S. retail gasoline prices would average about $3.70 per gallon for the summer driving season, and it noted that refinery closures and production constraints had already raised prices, crack spreads and household gasoline expenditures in prior summers.

That matters because the market can move in layers. Crude may ease, but if refiners are still tight, distribution costs are elevated or summer demand is climbing, pump prices may not fall as fast as headlines suggest. In that sense, slow declines can be a feature of the market rather than a sign that every station is withholding savings.

How to tell a normal lag from a problem

The cleanest test is whether local prices are still tracking the real costs of fuel. If crude and wholesale prices have eased, but retail prices remain unusually elevated for an extended period without a clear supply-chain reason, that is when the gap deserves scrutiny. A market-wide delay can reflect replacement-cost pricing and competition. A persistent disconnect, especially if it lasts well after the input costs have normalized, is harder to explain away.

The industry’s explanation is strongest when wholesale costs are moving quickly, station owners are competing aggressively and tanks are being refilled at the new higher price. It is weaker if the same market keeps prices high long after the pressure has passed. Because gasoline pricing includes crude, taxes, refining, distribution and marketing, drivers should look at the whole chain before assuming any one part is responsible.

The bottom line is that gas prices are not moving randomly. They are transmitting global oil shocks, local competition, tax burdens and retailer margins through a system that raises prices quickly when costs rise and lowers them grudgingly when costs fall. That is the rocket-and-feather pattern at work, and it is exactly why the number on the pump can feel so unfair even when it is still following the market.
