Gas Prices Are Swinging: How to Budget for Volatility

The national average for a gallon of regular gasoline stood at $3.884 on July 10, 2026 — up 5 cents overnight and reversing a weeks-long decline. But the real story isn’t the price itself; it’s the whiplash. American drivers have watched gas swing from a low of $2.79 in January to a peak of $4.56 in May, and back down to $3.83 before climbing again. The rollercoaster, driven by the on-again, off-again US-Israel war with Iran and disruptions to the Strait of Hormuz, is creating financial anxiety for millions of households.

“How bad is it going to be this time? Is it going to be not as bad as I think, or is it going to be worse than I think?” said Emily Blain, an accredited financial counselor in Minnesota, describing the stress her clients feel. “Since many people are going to the gas pump fairly often, that absolutely adds up,” she told NPR.

Why Gas Prices Are So Unpredictable

The volatility traces back to the Strait of Hormuz, a narrow waterway through which roughly 20 million barrels of oil per day normally flow — about one-fifth of the world’s supply. Since the US and Israel launched their war on Iran in late February, the strait has been repeatedly disrupted. When fighting intensifies, prices spike; when ceasefires take hold, they fall. The latest surge followed President Trump’s declaration that the ceasefire was “over” after Iran attacked tankers near the strait, sending Brent crude jumping nearly 6% to over $80 a barrel.

This pattern of unpredictability is historically unusual. US motor fuel prices have jumped as much as 35.8% annually and fallen as much as 27.8% over the last two decades, according to the USDA Economic Research Service. But the speed and frequency of the current swings are exceptional. Lauren Swift, senior editor for Autotrader and Kelley Blue Book, noted that historically, when “gas prices have seen a sharp uptick due to war or other global conflicts, they take a very long time to come back down, typically years.”

How Volatility Affects Consumer Behavior

Data from the cash-back app Upside reveals that when prices rose sharply in March, drivers visited gas stations more often but bought less fuel each time. “Some drivers can’t afford to fill up their tank at a given time, so there’s definitely some cash constraints,” said Thomas Weinandy, principal research economist at Upside. Others stick to habits like saying “put $20 on pump 1” — a routine that now buys significantly fewer gallons than it did in January.

When prices fall, the pattern reverses: drivers buy more per visit, a trend that emerged in June data. But the uncertainty itself takes a toll. Gas currently accounts for only about 1.7% of a typical household budget — near an all-time low — yet the unpredictability causes disproportionate stress. “You never know what you’re going get, to a certain extent,” Blain said. “That feels really uncomfortable regardless of the actual dollar-and-cent impact.”

Budgeting Strategies for Volatile Prices

Financial experts emphasize that while drivers can’t control global oil markets, they can control how they prepare. Kimberly Palmer, personal finance expert at NerdWallet, put it bluntly: “There is not much control you have over the prices, so all we can really do is to prepare to pay more at the pump.”

Here are the key strategies experts recommend:

Assume the price will be high. Build higher gas costs into your budget proactively. “If we plan ahead knowing that gas prices are expected to be higher, then it can be a nice surprise if they end up going down that week,” Palmer said. If prices drop instead, you’ll have surplus money.

Shop around for the best price. Apps like GasBuddy and Upside can help find cheaper stations. Driving even a few miles out of your way could save substantially per gallon.

Use less gas. Cutting back on driving is the most direct approach. Fuel-saving habits — driving smoothly, keeping tires inflated, removing excess weight from your vehicle — can also make a meaningful difference. If within budget, switching to an electric vehicle can eliminate exposure to gas price swings entirely.

Build a financial cushion. Spending less on gas now creates a buffer for when prices inevitably rise again.

Who Feels the Pain Most

A NerdWallet analysis found that a $0.50-per-gallon spike could cost drivers in the most price-sensitive states around $500 more per year. The states most affected — Wyoming, Oklahoma, Montana, and North Dakota — tend to have longer driving distances, lower fuel efficiency (pickup trucks dominate), and lower median incomes, compounding the burden. For a two-driver household in these states, the annual hit could exceed $1,000.

At the other end of the spectrum, drivers in Rhode Island, New York, California, and Washington are less sensitive to price changes due to shorter commutes and more fuel-efficient vehicles.

The Bigger Picture

The broader economic impact extends beyond the pump. Inflation rose to 3.3% in March, the highest since May 2024, driven largely by energy costs. Higher diesel prices are increasing the cost to transport goods, potentially raising grocery prices. Jet fuel costs have risen over $2 a gallon, leading to higher airfares and new bag fees. Moody’s Analytics chief economist Mark Zandi told CBS News that “the damage has already been done” and oil prices are unlikely to return to pre-war levels anytime soon.

What to Watch For

The immediate outlook depends on whether a new ceasefire can be reached. The burial of Iran’s Supreme Leader Ayatollah Ali Khamenei and the uncertain political transition in Tehran add significant geopolitical uncertainty. Analysts note that the global oil market has shown remarkable adaptability — the effective supply loss from the Strait of Hormuz disruption was far smaller than initially feared — but the renewed hostilities suggest further price swings ahead.

For consumers, the message from experts is consistent: prepare for the worst, hope for the best, and build flexibility into your budget. In a market where the only certainty is uncertainty, that may be the most valuable strategy of all.
