Los Angeles County hit $4.88 per gallon by March 7, 2026. California’s statewide average crossed $5.00 — the only state in the country above that threshold. The national average sat at $3.32, up from $3.00 a week earlier, the sharpest one-week increase in two years. Politicians from both parties are attributing this entirely to the Iran conflict, which is technically accurate and functionally misleading. The Iran war explains the trigger. It does not explain why American households were already carrying the weight before the first bomb dropped.
This Is Not Just an Iran War Story
The standard framing is straightforward: U.S. and Israeli strikes on Iran beginning February 28, 2026 sent oil markets into shock. WTI crude jumped to $90.90 per barrel — the biggest single-day gain since April 2020, according to Reuters. The Strait of Hormuz, through which approximately 20% of global oil supply flows daily, effectively closed as insurers refused coverage for tankers attempting passage after Iranian drone strikes. Iraq, OPEC’s second-largest producer, cut output by 1.5 million barrels per day. Qatar halted operations at the world’s largest LNG export facility. This is a genuine supply crisis, and it is legitimately driving prices up.
But gas prices had already been climbing before the Iran conflict, and the reason is standing policy: Trump’s tariffs on Canadian and Mexican energy imports, in effect since early 2025. The U.S. imports approximately 40% of its crude oil, with roughly half coming from Canada. A 10% tariff on Canadian energy and a 25% tariff on Mexican imports took effect in March 2025. Reuters reported at the time that Northeast states — which rely heavily on Canadian refined fuel — faced immediate increases of 20 to 40 cents per gallon. Canadian refiner Irving Oil raised prices on fuel products the day the tariffs kicked in. Economists and analysts at Bloomberg, Reuters, and MarketWatch all warned explicitly that Trump’s promise to lower gas prices was structurally incompatible with his tariff policy. He promised both and delivered neither.
Trump Said “If They Rise, They Rise”
When asked about rising gas prices during the Iran operation, Trump told reporters: “If they rise, they rise.” According to Yahoo News, White House officials privately warned this posture would be “catastrophic” for Republicans in midterm elections. That is an admission that the political team understands exactly what the policy team is doing to household budgets — and that the political team is worried about the midterms, not the groceries.
This matters because Trump ran in 2024 on energy affordability. The campaign promise was explicit: energy dominance, lower prices at the pump, relief from Biden-era inflation. The tariff structure then placed a levy on the exact Canadian and Mexican energy imports that U.S. refineries depend on to produce gasoline. As Bloomberg noted, imposing 25% tariffs on Canadian oil is “like shooting yourself in the foot” for refineries that need heavy Canadian crude to operate. The contradiction was flagged in real time by every major energy analyst. The administration proceeded anyway.
Now the Iran war has landed on top of a tariff-inflated base price. The $5.00+ California average is not attributable solely to Hormuz. It is the sum of: (1) a tariff-driven increase in refining input costs that has been accumulating for over a year; (2) seasonal transition to summer-blend gasoline that typically adds 15-25 cents per gallon; and (3) the Iran conflict shock that added approximately $10 per barrel to crude costs in a single week. The Los Angeles driver filling their tank is paying for all three simultaneously.
The Household Math Is Not Abstract
For every $10 increase in crude oil prices, consumers pay roughly 25 cents more per gallon at the pump, according to Investopedia and CNBC analysis. At current trajectories, Goldman Sachs calculates traders are demanding approximately $14 more per barrel as a risk premium for Hormuz exposure. The oil market has already priced in a risk scenario that assumes the strait remains effectively closed for weeks.
The household cost calculator is not favorable. Research from MyCrisisCost estimates that at $100 per barrel oil — well within analyst projections if the Iran conflict continues — the average U.S. household faces $437 to $900 in additional annual costs, including fuel, energy bills, and grocery price pass-throughs. At $150 per barrel, that climbs to approximately $1,200. These are not abstract economic forecasts. They are what happens when you put food in a cart, fill a tank, and open a utility bill.
The S&P 500 fell for multiple consecutive days in early March 2026. A weak jobs report on March 6 raised stagflation concerns — the combination of rising prices and slowing growth that central banks are poorly equipped to address. The Federal Reserve faces a choice between fighting inflation with rate increases that further slow hiring, or holding rates to protect employment while inflation runs. Neither option is comfortable. Both were avoidable.
What This Actually Means
The $7+ Los Angeles average is the visible number, but the structure behind it is what matters. The tariffs were a policy choice made with full knowledge of the energy import dependency. The Iran war was a military choice made with some knowledge of oil market fragility. The administration’s response to rising prices — “if they rise, they rise” — is a political choice to treat household budgets as acceptable collateral damage in a geopolitical project.
Economists warned this would happen. They warned it when the tariffs were announced in early 2025. They warned it when the Iran military option was being discussed. The warning was correct. The warning was ignored. The question now is not whether the price spike was foreseeable — it was, repeatedly, by credible institutions. The question is whether the political cost of that choice lands where it belongs: on the officials who made it and the campaign promises that turned out to be incompatible with actual policy.
Background
What is the Strait of Hormuz? The Strait of Hormuz is a narrow waterway between Iran and Oman connecting the Persian Gulf to the Gulf of Oman. Approximately 20% of global oil supply passes through it daily — roughly 20 million barrels — along with a significant portion of global liquefied natural gas exports. Iran has repeatedly threatened to close the strait in response to military pressure. An effective closure, even through the insurance-driven mechanism currently in effect, creates immediate supply disruption for global oil markets.
