The reason drivers still feel “slammed” at the pump even as headline crude prices retreat is that retail fuel costs reflect a complex chain of disruptions and frictions—from a war‑shuttered Strait of Hormuz to refinery bottlenecks, taxes, and emerging algorithmic pricing—rather than crude alone.

Key Points

• Crude oil is the largest single driver of gasoline prices, but wars and chokepoint closures add layers of cost in shipping, insurance, refining, and taxation that crude benchmarks do not capture.
• In the Iran–Strait of Hormuz crisis, large volumes of supply were shut in and rerouted; that shock raised wholesale and refined product prices worldwide even where crude later eased.
• Retail prices are “asymmetric”: they rocket up quickly when crude rises and fall back slowly when crude drops, a pattern explained largely by inventory dynamics and competitive behavior, not always by collusion.
• Algorithmic pricing tools and antitrust lawsuits have surfaced a credible secondary concern—software that may be hardening margins by coordinating price responses across thousands of stations.
• For consumers and policymakers, the practical lesson is that focusing only on crude prices or “gouging” misses the interaction of supply shocks, structural taxes, refining constraints, and new pricing technology.

How Retail Fuel Prices Are Built: Beyond the Barrel of Crude

To understand why fuel prices can stay high while crude falls, you have to disaggregate the price of a gallon at the pump. In the United States, the Energy Information Administration and industry analyses converge on a simple picture: crude oil typically accounts for about half to two‑thirds of the retail gasoline price, with the rest split among refining costs and profits, distribution and marketing, and taxes. When crude moves sharply, its weight in that mix means gasoline prices usually follow—but only “usually.”

Since the post‑2020 recovery, econometric work has shown that crude prices explain more than 90 percent of the variation in average U.S. gasoline prices on a quarterly basis, especially when oil is rising. That statistical dominance underpins the industry’s claim that crude remains the primary driver of pump prices. But the residual 10 percent is not noise; it is where shipping disruptions, refinery outages, regional taxes, and local competition—or lack of it—lurk. Those factors become decisive when war hits a major supply route.

The Strait of Hormuz Shock: What Happens When a Global Artery Closes

The Iran war and closure or near‑closure of the Strait of Hormuz are central to the current episode. Hormuz is not just “another shipping lane”; it is the choke point through which roughly a fifth of global oil trade flows in normal times. When Iranian missiles, drones, and formal closure declarations pushed tankers to drop anchor or reroute, the world did not lose a few marginal barrels. Analysts variously estimate that 10–14 million barrels per day were effectively shut in or delayed at the peak of the crisis.

This scale of disruption forces refiners and traders to pay more for replacement barrels, reroute cargoes around longer paths, and shoulder war‑risk insurance premiums that jumped from fractions of a percent of ship value to several percent. All of those costs sit between the wellhead and the pump. They can raise the delivered cost of gasoline and diesel even if futures prices for benchmark crude, traded in financial markets thousands of miles away, begin to cool as traders anticipate ceasefires or strategic reserve releases.

Global data from the Iran conflict bear this out. Statista’s compilation shows gasoline prices jumping by more than 50 percent in parts of Asia and the Middle East after the war began, with especially steep increases in net importers highly dependent on Middle Eastern supply. Zero Carbon Analytics similarly documents how fossil fuels drove a large share of inflation in importing economies during the conflict, underscoring that supply‑chain frictions—not just spot crude—pushed energy costs higher.

Why Gasoline Can Stay High When Crude Falls: Asymmetry and Lag

Once the immediate shock passes and crude benchmarks retreat, consumers expect pump prices to fall in lockstep. Research going back decades shows they do not. Economists describe gasoline price behavior as “rockets and feathers”: prices shoot up quickly when crude rises and then drift down slowly once crude declines.

Several mechanisms explain this asymmetry. First, inventory: retailers refill their tanks at elevated wholesale prices during the shock, and they recoup those costs over subsequent weeks, not overnight. Second, menu costs and competitive dynamics: stations are quick to raise listed prices to avoid losses when wholesale jumps, but they are more cautious and staggered when cutting prices, especially if nearby competitors hold firm. A Dallas Fed survey of empirical studies finds that asymmetric pass‑through from crude to gasoline can emerge even in competitive markets, without needing collusion as the primary explanation.

Third, taxes and other fixed components keep a floor under retail prices. Federal and state fuel taxes typically represent around 14 percent of the pump price in the U.S., and some jurisdictions add environmental or congestion charges that are insensitive to crude swings. When crude falls, those embedded levies do not, so the proportion of the retail price attributable to non‑crude factors rises, visually flattening the decline for consumers.

Evidence of Divergence: Crude Back to Pre‑War, Gas Still Elevated

In the present episode, this familiar pattern is visible in the data. Reporting from NBC News and The Hill notes that West Texas Intermediate crude fell back toward about $69 per barrel—essentially its pre‑war level near $67—after initial war‑driven spikes. Yet national average gasoline prices remained around $3.90 per gallon, nearly $1 higher than late‑February levels, leaving pump prices roughly 44 percent above where they stood before the conflict.

At another point, crude futures softened on optimism over a potential Iran deal, while average U.S. gas prices climbed to about $4.54 per gallon. The BBC reported that UK diesel prices experienced their steepest monthly fall in 26 years as wholesale markets eased, but gasoline remained stubbornly elevated, illustrating that even within fuel types, price transmission can be asymmetric.

Those divergences are not proof of wrongdoing on their own; they are what one would expect when inventories, taxes, and refining bottlenecks interact with a large, but gradually normalizing, supply shock. Still, they set the stage for a second controversy: whether new pricing technology has turned “rockets and feathers” from a passive market quirk into an actively managed strategy.

The Algorithmic Pricing Lawsuit: A New Layer of Concern

The California lawsuit against Calibrate Fuel Systems and major retailers—BP, Walmart, Marathon, and others—alleges that AI‑driven software has pushed pump prices about 30 cents per gallon above what traditional competition would yield. Calibrate’s tools ingest competitor prices, traffic data, demand signals, and wholesale costs to recommend “optimal” prices station by station. On its face, that is dynamic pricing, a practice long used in airlines and hotels. The plaintiffs’ claim is more pointed: that common reliance on the same optimization engine amounts to coordinated behavior that dampens price competition.

The case is at an early stage. There is, so far, no court‑validated forensic analysis showing that Calibrate’s algorithms systematically produce anti‑competitive prices as opposed to merely accelerating the existing rockets‑and‑feathers pattern. Federal antitrust investigations by the Department of Justice and Federal Trade Commission into algorithmic pricing across sectors indicate regulators take the risk seriously, but regulators’ interest is not itself proof that this explains current fuel prices.

From an economic standpoint, the concern is plausible. If thousands of stations feed real‑time data into a shared system that recommends prices designed to maximize collective margin while avoiding undercutting, then the micro‑level adjustment process that once generated gradual, competitive price declines could be replaced with a coordinated reluctance to cut. Whether that has happened at scale remains to be seen. For now, algorithmic pricing is best understood as a potential amplifier of existing asymmetry rather than a proven primary cause of elevated prices.

Supply, Demand, and Inelasticity: Why Consumers Keep Paying

Even without algorithms, the basic supply‑and‑demand conditions facing motorists make them vulnerable during shocks. Fuel demand is relatively price‑inelastic in the short run: people still need to drive to work, freight still needs to move, and substitutes are limited. Studies summarized by the Federal Highway Administration and others find that long‑run fuel demand elasticities cluster around −0.6 to −0.8, meaning a 10 percent price increase eventually yields only a 6–8 percent drop in consumption, largely via gradual improvements in fuel economy rather than large reductions in miles driven.

In acute crises, that inelasticity supports higher prices. When a supply route like Hormuz is disrupted and refiners scramble for barrels, wholesalers and retailers know that demand will not collapse in response to a 30 or even 50 percent price jump. Households and firms absorb the shock through budget cuts elsewhere, and inflation in fuel‑importing countries rises accordingly. IMF work on fuel price pass‑through shows that retail fuel prices—not crude benchmarks—are the better predictor of headline inflation, precisely because they embed taxes and margin behavior that crude futures ignore.

Are High Prices “Gouging” or the Cost of Fragile Supply Chains?

Public anger often coalesces around the word “gouging,” and in some corners of media and politics, that narrative now dominates the discussion of fuel costs. Yet a careful read of the evidence does not support a simple story of pervasive collusion. Analyses like those from the American Energy Alliance have found little systematic proof that past episodes of asymmetric price behavior were driven by broad, coordinated misconduct rather than by a combination of global crude movements, OPEC+ decisions, refinery outages, and seasonal demand shifts.

That does not exonerate every market participant in every region, nor does it rule out narrow cases where algorithmic tools or local concentration allow firms to exploit shocks. It does suggest that any serious diagnosis must begin with the structure of supply chains and the realities of inelastic demand. The Iran–Hormuz crisis shut in a sizable share of global supply, forced costly rerouting, and exposed the fragility of trade routes that carry not just oil but food and other commodities. Governments responded with strategic petroleum reserve releases and coordinated actions through bodies like the International Energy Agency, demonstrating they can partially cushion shocks—but reserves are finite, and they are political tools as much as economic ones.

What This Means for Consumers and Policy

For drivers, the key takeaway is that watching crude prices alone will not tell you what to expect at the pump. Retail fuel prices embody the full chain from wellhead to refinery to storage tank to station sign, plus the emerging influence of software that sets those signs. They respond quickly to geopolitical risk and slowly to its resolution. They transmit not just the cost of oil but the cost of fragility in the energy system.

For policymakers, two tracks matter. One is hardening the physical system: diversifying supply away from chokepoints, investing in refining resilience, and accelerating the shift toward lower‑volatility energy sources that are less exposed to single‑route disruptions. The other is scrutinizing the pricing system: ensuring antitrust law can address coordinated algorithmic behavior if it emerges, improving transparency around how retail prices are set, and resisting the temptation to explain every uncomfortable asymmetry as gouging without evidence.

The Iran–Hormuz episode is not the first time fuel prices have decoupled from crude benchmarks during a conflict, and it will not be the last. As long as global energy trade relies on a small number of vulnerable arteries and consumers have few short‑term alternatives to gasoline and diesel, shocks will ripple through to the pump in ways that feel unfair long after crude prices appear to have normalized.
