Drivers have had a stretch of relief at the pump, but it may be ending. The US national average for regular gasoline is around $3.87 a gallon and has begun climbing again, rising close to eight cents over the past week to about $3.855 as of July 13, according to weekly data compiled from the Energy Information Administration. The reason to watch it now is what is happening in the oil market.
The oil connection
Gasoline is refined from crude oil, so the price of crude is the single biggest input into what you pay at the pump. This week crude jumped: Brent, the international benchmark, and West Texas Intermediate, the US grade, both rose to roughly one-month highs, near $85 and $80 a barrel respectively, as the United States and Iran traded strikes and fears grew over the Strait of Hormuz, the Gulf chokepoint for a large share of the world's oil, according to Al Jazeera.
Crucially, that increase does not show up at the pump right away. Crude has to be refined and shipped through terminals to filling stations, a process that plays out over weeks, so a jump in oil today tends to reach drivers gradually rather than overnight. The lag also works in reverse, which is why pump prices fall slowly after oil drops.
What "toward $4" would cost you
Whether the average actually reaches $4 depends on how high crude goes and how long the tension lasts, so treat it as a risk rather than a forecast. But the arithmetic of a move from about $3.87 to $4.00 is easy to see. On a 15-gallon fill-up, roughly two dollars more per tank. For a household filling up about once a week, that is on the order of $100 more over a year, money that comes straight out of the rest of the budget.
It is a modest sum next to a mortgage or groceries, but gasoline has an outsized effect on how people feel about prices, because it is bought often and its cost is posted in foot-high numbers on every corner.
What to watch, and what not to do
The honest answer is that no one can tell you where pump prices go next; it hinges on an unpredictable geopolitical situation and on the oil market's reaction to it. Forecasters at bodies like the EIA publish projections, but even they revise them as events change, and this week's flare-up came after their latest estimates.
For a household, the useful response is boring and durable rather than reactive: the swings in gas prices are largely outside your control, so the levers that help are the ordinary ones, combining trips, keeping tires properly inflated, and not panic-buying premium fuel a car does not need. This is not investment advice, and it is certainly not a reason to change long-term plans over a two-dollar move in a tank of gas. It is simply a heads-up that the cheap-gas stretch of early summer may be giving way, and why.
