Drivers across Houston are facing renewed sticker shock at the pump after the fragile ceasefire between the United States and Iran broke down this week, sending crude oil prices jumping roughly 7% overnight. The average price of regular unleaded gasoline in the U.S. stood at $3.85 per gallon on July 9, according to AAA, and experts say Houston motorists should brace for further volatility in the coming weeks.

The seesawing prices have been a hallmark of 2026. Gas prices peaked nationally at $4.56 per gallon in May before falling back, only to climb again as hostilities in the Strait of Hormuz resumed. President Donald Trump declared an end to the ceasefire on July 8, and the U.S. military struck dozens of targets along the Iranian coastline overnight, according to NPR. The Dow Jones Industrial Average tumbled more than 800 points in response.

For Houston, a city deeply tied to the energy sector, the implications cut both ways. Higher oil prices can boost revenues for exploration and production companies headquartered in the region, but they also squeeze consumers and businesses that depend on transportation. Emily Blain, an accredited financial counselor quoted by NPR, noted that fluctuating expenses like gas have a more immediate psychological impact on consumers than predictable annual costs like rent increases. “You never know what you’re going to get, to a certain extent,” Blain said. “That feels really uncomfortable regardless of the actual dollar-and-cent impact.”

Data from the cash-back app Upside shows that when gas prices rise, drivers visit stations more frequently but buy less fuel each time. Thomas Weinandy, Upside’s principal research economist, told NPR that some drivers simply cannot afford to fill their tanks at higher prices, while others maintain habits like spending a fixed $20 per visit, which now buys fewer gallons.

The financial website NerdWallet found that a $0.50-per-gallon price increase could cost drivers in some states around $500 more per year. Kimberly Palmer, a personal finance expert at NerdWallet, recommends that Houston households budget assuming prices will remain high. “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.

Houston’s sprawling geography and limited public transit options make residents particularly vulnerable to gas price swings. The metropolitan area spans more than 10,000 square miles, and many commuters drive long distances to work in the energy corridor, downtown, or the sprawling suburban office parks that dot the region. For these drivers, fuel costs represent a significant line item in household budgets.

Lauren Swift, senior editor for Autotrader and Kelley Blue Book, told NPR that historically, when gas prices surge due to war or global conflicts, they take a very long time to come back down — typically years. That projection, if accurate, means Houston residents could be dealing with elevated pump prices well beyond the current cycle of hostilities.

The renewed volatility also complicates the Federal Reserve’s task. The CME FedWatch tracking tool now shows a better than 1-in-3 chance that the central bank will raise interest rates this month, up from about 1-in-4 before the ceasefire collapsed. Higher rates would affect everything from mortgage applications to auto loans for Houston residents already grappling with inflation above the Fed’s 2% target.

For now, Houston drivers can take several practical steps. Using apps and websites to shop around for the best price, adopting fuel-saving driving habits such as smooth acceleration and proper tire inflation, and building a buffer into monthly budgets can all help mitigate the impact. Some may also consider accelerating plans to purchase electric or hybrid vehicles, though that option remains out of reach for many households.

The International Monetary Fund, which already downgraded its 2026 global growth forecast to 3% from 3.5%, warned in its latest outlook that “the possibility of renewed Middle East conflict looms large and could extend commodity price volatility, further threaten supply chains, raise prices, and weigh on financial conditions.” For Houston, a city that lives and breathes energy, that warning resonates on every level — from the boardroom to the gas station.

The energy industry’s dual role as both beneficiary and victim of price volatility is on full display in Houston. Major oil companies with headquarters in the region, including ExxonMobil and Chevron, have seen their stock prices respond positively to the renewed hostilities, as higher crude prices improve the economics of production. However, the downstream refining and petrochemical sectors face higher input costs, and the city’s large logistics and transportation businesses are absorbing fuel cost increases that may eventually be passed on to consumers.

Houston’s small business community is particularly sensitive to gas price fluctuations. Many small businesses — from delivery services to landscaping companies — depend on vehicles for their operations. A sustained increase in fuel costs can erode already thin margins, forcing businesses to either raise prices or absorb the losses. The National Federation of Independent Business has noted that energy costs are consistently among the top concerns for small business owners in Texas.
