The math at the pump: Before you blame Trump, follow the damn barrel

 Gasoline has become one of America’s favorite political intelligence tests, because the moment the numbers on the sign change, half the country forgets how commodities work. Gas goes down and whichever president you like deserves a parade; gas goes up and whichever president you hate apparently crawled out of bed at four in the morning, drove to every Chevron in America and changed the numbers personally. It would almost be funny if ordinary Americans weren’t watching eighty dollars disappear into an SUV while television competes to provide the dumbest possible explanation.

As of September 25, AAA puts the national average for regular gasoline around $4.49 per gallon, compared with roughly $3.16 a year ago. AAA identifies expensive crude oil and volatility surrounding the Strait of Hormuz as major pressures, while gasoline demand rose from 8.79 million to 8.84 million barrels per day, inventories fell from 207.7 million to 206 million barrels and gasoline production slipped slightly. Several variables are moving before Donald Trump’s name even enters the conversation.

Iran and Hormuz absolutely matter. EIA says disruptions to petroleum flows through Hormuz contributed to higher and more volatile oil prices during 2026 while pushing international buyers toward alternative supplies and increasing U.S. refinery margins, production, and exports. The conflict can therefore hit gasoline twice: through crude prices and through global competition for finished petroleum products.

What I reject is the lazy explanation that says, “There’s a war in Iran, therefore gas is expensive.” That is like explaining a hamburger’s price by showing me the cost of a cow while ignoring the slaughterhouse, trucking company, restaurant, taxes, labor, and the gentleman behind the counter who apparently believes adding bacon now requires financing.

Crude is the raw material, not the finished product. EIA breaks gasoline prices into crude-oil costs, refining costs and profits, taxes, and distribution and marketing. Showing only a crude-oil chart is showing one chapter of the book and pretending you’ve read the ending.

Refining is especially important because EIA reported in September that elevated crude prices and elevated crack spreads are contributing to higher pump prices. Crack spreads measure the difference between the value of refined products and the crude used to produce them. When those spreads become unusually large, refining becomes a much bigger part of what motorists pay.

That makes Trump’s claim of possible price-gouging worth examining rather than dismissing with another meme. In June, crude prices had fallen sharply from their May peak while gasoline declined much less. Trump ordered the Justice Department to examine why consumers weren’t receiving comparable relief, and questioned whether major oil companies were gouging motorists.

That does not prove illegal conduct. High margins can occur when refining capacity becomes scarce, inventories tighten, transportation is disrupted, or global buyers compete for limited supplies. But those conditions also make legitimate regulatory scrutiny appropriate.

The administration has done more than complain. The Justice Department’s Antitrust Division and Federal Trade Commission announced monitoring of petroleum markets for potentially illegal conduct contributing to high gasoline prices, and encouraged state attorneys general to examine possible antitrust and consumer-protection violations. Again, investigation is not proof of wrongdoing, but it complicates the claim that Trump is simply sitting around enjoying high prices.

The administration has also addressed supply. In August, the EPA, working with the Department of Energy, issued an emergency fuel waiver allowing broader E10 gasoline sales and ending certain summer-blend restrictions early, saying the move could increase available domestic gasoline supply.

Fuel specifications matter. EIA identifies regional requirements, refinery maintenance, unexpected outages, transportation constraints, consumption patterns, and inventories as factors affecting gasoline prices. California also requires specialized gasoline blends that cost more to manufacture, and can be difficult to replace quickly during refinery disruptions.

… Which helps explain why California can sit above six dollars while Texas remains below four under the same president. Unless Trump becomes dramatically more presidential when motorists cross the Texas state line, perhaps taxes, regulations, fuel specifications, infrastructure and regional supply deserve some attention.

Refinery outages matter, because crude sitting in a tank does absolutely nothing for somebody whose F-150 needs gasoline. Inventories matter because declining supplies combined with increasing demand create upward pressure. Distribution matters because gasoline must travel from refinery to terminal to tanker truck to neighborhood station, leaving prices vulnerable to pipeline disruptions, hurricanes, bottlenecks, and transportation costs.

Exports matter because American refineries do not operate inside a glass dome marked “For Americans Only.” Middle Eastern disruptions can increase foreign demand for U.S.-refined products, raising refinery margins and exports. Taxes matter because federal and state levies remain embedded in every gallon, and vary considerably across states.

Seasonality matters too. Gasoline usually gets cheaper as summer ends and demand softens, yet AAA says this September is on pace for a record national September average. Normal autumn relief is colliding with expensive crude, Hormuz volatility, tighter inventories, and elevated refining economics.

Now put all of that together and tell me again that the intellectually serious explanation is simply, “Trump made gas expensive.” You have to ignore Iran, Hormuz, crude markets, refinery margins, capacity, maintenance, outages, inventories, seasonal blends, state regulations, taxes, distribution, exports, demand and regional differences before finally arriving at the theory that the guy in the Oval Office personally controls the Speedway sign.

That isn’t analysis. That’s partisan ventriloquism.

There is legitimate criticism to make of Trump’s energy and foreign policy, including the reality that instability involving Iran and Hormuz has contributed to higher petroleum prices. If administration policy contributes to geopolitical instability affecting a major energy corridor, that belongs in the accounting too. Intellectual honesty doesn’t stop when facts become inconvenient for my side.

The better question is what happens when those pressures ease. If crude falls substantially, inventories recover, Hormuz traffic normalizes, and refinery margins remain extraordinarily high while motorists continue paying inflated prices, scrutiny of industry pricing becomes increasingly important.

Gasoline pricing should survive arithmetic. Show me crude. Show me refining. Show me taxes. Show me transportation. Show me inventories, regional specifications, and profit margins. Somewhere inside those numbers is the explanation glowing above the gas station.

Trump may be right that portions of the industry deserve scrutiny, while his critics are right that Iran and Hormuz exert upward pressure. Those positions can coexist because economics does not require joining a political fan club before using a calculator.

Gasoline is not red or blue, MAGA or progressive. It is a globally traded commodity moving through a complicated refining and distribution system. The next time somebody reduces all of that to a meme blaming one politician, ask them to do something apparently terrifying in modern political discourse: Show the entire math, not merely the number that helps your narrative.
