Updated Oct. 26, 2026: rewritten to explain how the Strait of Hormuz crisis affects US gas prices, with current numbers and money-saving steps.
Quick answer: The Strait of Hormuz is the narrow sea lane where about one-fifth of the world’s oil passes each day. Since the Iran conflict disrupted it, oil and gas prices have jumped. AAA put the US average at $4.29 a gallon on Oct. 25, 2026, up from about $3.06 a year earlier. Prices have eased from $4.49 a month ago as ship traffic improves, but they are still far above last year. War-risk insurance for tankers is one hidden reason.
Gas prices and the Hormuz crisis at a glance
| Measure | Number | Source |
|---|---|---|
| US regular gas average (Oct. 25, 2026) | $4.29 | AAA |
| One month earlier | About $4.49 | AAA |
| One year earlier | About $3.06 | AAA, via news reports |
| Brent crude (late October) | Around $116 a barrel | The Hill |
| Share of world oil through Hormuz | About one-fifth | US EIA |
Oil prices move every day, and reports in late October differed. Check AAA’s daily average for today’s number in your state.
Why a strait half a world away hits your gas tank
The Strait of Hormuz links the Persian Gulf to the open ocean. Oil from Saudi Arabia, Iraq, Kuwait, the UAE, Qatar and Iran moves through it. At its narrowest, the shipping lanes are only a few miles wide.
Oil is priced on a global market. When supply through Hormuz is blocked or slowed, buyers everywhere compete for fewer barrels. The US produces a lot of its own oil, but American gas prices still follow the global price of crude.
According to reports, Iran moved to close the strait after a large US-Israeli strike last winter. Traffic has improved in recent weeks, and that is one reason prices have come down from their peak.
How war-risk insurance raises prices
Every tanker carries insurance. Normal policies exclude war. So when a region turns dangerous, ship owners must buy extra war-risk insurance for each trip.
- Premiums can change within hours. Underwriters, many tied to the Lloyd’s of London market, reprice risk as attacks or threats happen.
- Cover is short-term. Policies often last only days, for a single voyage.
- The cost is passed on. Higher insurance, longer routes and crew danger pay all add to the cost of each barrel. That shows up in fuel prices.
When insurers see danger easing, premiums fall. That is one of the first signs prices at the pump may follow.
What it means for your budget
Higher fuel costs ripple through the economy:
- Gas: A family that buys 15 gallons a week pays about $18 more each week at $4.29 than at $3.06.
- Diesel and shipping: Trucks run on diesel, so groceries and online orders can cost more.
- Airfare: Jet fuel is a major airline cost, so ticket prices tend to rise.
- Heating: Homes that heat with oil or propane may see higher winter bills.
Made-up example (not real people): These are made-up examples to show the math.
The Garcias, Phoenix drive two cars and buy about 20 gallons a week. At $1.23 more per gallon than last year, they pay about $24.60 more a week, or roughly $1,280 a year.
Kim, Chicago commutes by train and fills up 8 gallons a week. The same price jump costs Kim about $9.84 a week, or around $510 a year.
8 ways to save on gas right now
- Compare prices with an app like GasBuddy before filling up. Prices can differ by 30 cents or more within a few miles.
- Join a grocery or warehouse fuel program. Kroger, Costco, Sam’s Club and others offer discounts.
- Use a gas rewards credit card only if you pay the balance in full each month.
- Keep tires inflated. The US Department of Energy says proper inflation helps fuel economy.
- Drive smoothly. Hard braking and fast starts waste fuel.
- Remove roof racks and heavy cargo when you do not need them.
- Combine errands into one trip.
- Do not buy premium unless your owner’s manual requires it.

Common mistakes when gas prices spike
- Panic buying or hoarding fuel in cans. It is unsafe and can cause local shortages.
- Driving far to save a few cents. A 10-mile detour can cost more than it saves.
- Falling for “fuel saver” gadgets. The FTC has warned that most devices claiming big mileage gains do not work.
- Locking into a bad car loan. Do not rush into a new vehicle just because of a price spike that may ease.
Where your $4.29 a gallon goes
The price at the pump is made up of four main parts. The US Energy Information Administration tracks them every month.
| Part of the price | What it covers | How Hormuz affects it |
|---|---|---|
| Crude oil | The raw oil, usually the biggest share | Rises directly when supply is disrupted |
| Refining | Turning crude into gasoline | Can rise if refineries pay more for crude or insurance |
| Distribution and marketing | Trucks, pipelines, gas stations | Small effect, mostly from diesel costs |
| Taxes | Federal tax of 18.4 cents a gallon plus state taxes | No change; taxes are fixed per gallon |
Because crude oil is the largest piece, a big jump in oil prices shows up at the pump within days or weeks. Prices usually fall more slowly than they rise, a pattern economists call “rockets and feathers.”
Why prices differ so much by state
Your state can matter as much as world events. California usually has the highest prices because of higher taxes and special cleaner-burning fuel rules. States along the Gulf Coast, like Texas and Louisiana, are often cheaper because they sit near major refineries. AAA posts each state’s average daily, so check yours before a road trip.
Does the US have a backup supply?
Yes. The Strategic Petroleum Reserve is a federal stockpile of crude oil stored in underground salt caverns in Texas and Louisiana. Presidents can release oil from it during supply emergencies. Releases can calm prices for a while, but the reserve cannot replace a long disruption of world supply on its own.
Who gets hit hardest
High gas prices do not hurt everyone equally. Rural drivers often travel longer distances with no transit option. Gig workers who drive for delivery or ride-share apps pay for their own fuel. Truckers and small businesses that rely on vans pass costs along or absorb them. Lower-income households spend a bigger share of their budget on fuel. If you drive for work, track your miles, because some work driving can be deductible or reimbursed.
Should you change cars because of gas prices?
Usually not in a rush. A new car payment can easily cost more each month than you would save on fuel. Before switching, compare total costs: the payment, insurance, fuel and maintenance. If you were already planning to replace your car, a hybrid or electric model may lower fuel costs. FuelEconomy.gov lets you compare yearly fuel costs side by side.
What to watch next
- Tanker traffic through Hormuz. Steady flows usually mean lower prices within weeks.
- War-risk insurance rates. Falling premiums are an early sign of calmer markets.
- AAA’s weekly price updates. AAA says the switch to cheaper winter-blend gasoline is also helping prices fall this fall.
- OPEC+ output decisions, which can add or remove supply.

FAQ
Why are gas prices still high if Hormuz traffic is improving?
Oil markets react slowly, and stations price off fuel they bought earlier. Insurance and shipping costs also stay high until traders trust that the route is safe.
Does the US get much oil through the Strait of Hormuz?
Less than it once did, because the US now produces a lot of its own oil. But oil is a global market, so a supply shock anywhere raises prices here too.
What is war-risk insurance?
It is extra coverage ship owners buy to sail through conflict zones. Regular marine insurance excludes war damage, so this separate cover is needed and can be very expensive.
Will gas prices go down before the holidays?
No one can say for sure. AAA says winter-blend gas is helping, and prices fell over the past month. A new attack or closure could reverse that quickly. This is not a forecast.
Bottom line
The Strait of Hormuz is a tiny waterway with a huge effect on your budget. When it is disrupted, oil, insurance and shipping costs rise, and Americans pay more at the pump. Prices have eased lately, but at $4.29 a gallon they are still well above last year. Shop around, keep your car efficient, and watch tanker traffic news for clues about what comes next.
