Money MoveGas prices jumped 11 cents overnight. If you filled up yesterday, you got lucky.
The national average hit $3.109 on March 3, up from $2.997 the day before, according to AAA's fuel price tracker. That's the biggest single-day spike in months, and it's not random. It's the Iran conflict.
What's happening
The U.S. launched open-ended strikes against Iran, and the Strait of Hormuz, one of the world's most critical oil shipping lanes, started grinding to a halt. Oil prices jumped from $70 to nearly $80 a barrel over the weekend, per Insurance Journal.
The Strait of Hormuz handles roughly 20% of the world's oil supply. When it slows down, prices go up everywhere.
How this hits car owners
Gas prices are climbing fast. The national average is up 23 cents from a month ago ($2.883 to $3.109). That's roughly $3 to $4 more per fill-up for a typical sedan, and $5 to $6 more for trucks and SUVs.
Parts and repairs could get more expensive. Automotive News reports the conflict is disrupting shipping lanes that carry auto parts. If the situation drags on for weeks, as analysts expect, repair shops may start passing those costs along.
New car prices aren't helping either. U.S. new car and light truck sales dropped for the second month in a row in February, hurt by lower EV demand and elevated pricing. The market was already tight before this.
What you can do right now
Lock in gas prices where you can. Apps like GasBuddy can help you find the cheapest stations near you. Some warehouse clubs (Costco, Sam's Club, BJ's) are still significantly cheaper than street prices.
Don't panic-buy a new car. Prices are elevated, inventory is mixed. If you can wait, wait. If you can't, negotiate hard. Dealers are sitting on stock they need to move.
Watch your insurance. Rising car values and repair costs tend to push premiums up with a lag. If your renewal is coming up in the next few months, shop around now before carriers adjust.
Track what you're actually spending. Most people underestimate their total car costs by 30% to 40%. Between gas, insurance, maintenance, and loan payments, the real number is almost always higher than you think. Knowing your number is the first step to cutting it.
The bigger picture
JPMorgan economists warned this weekend that the conflict, layered on top of ongoing trade disruptions, could "reignite concerns over global stability." The Fed is still expected to cut rates twice this year, but that timeline gets shakier if inflation spikes from energy costs.
For car owners, the math is simple: everything car-related just got a little more expensive, and it might stay that way for a while.
The best move? Know exactly what your car is costing you. Then start cutting.
