Gen Z finally had room to breathe. Now Trump’s 26% gas price hike has them suffocating

For the first time in years, Gen Z was winning. Rents had finally stopped devouring their paychecks, wages were rising faster than their housing costs, and a generation that had long trailed older Americans in spending growth was starting to actually open its wallet — on restaurants, new clothes, electronics, even travel. Then came the oil shock, brought on by President Donald Trump’s widely expected and yet also still surprising decision to go to war on Iran.

A recent report from the Bank of America Institute shows that after nearly two years of trailing other generations in spending, Gen Z’s year-over-year spending growth surpassed Baby Boomers’ in mid-2025. Millennials followed suit in December 2025, outpacing older generations for the first time in roughly three years. The turnaround was real, data-driven, and — for a generation that came of age during pandemic shutdowns and an inflation crisis — long overdue.​

“Both Gen Z and Millennials may be even more prone to cutting back on ‘nice-to-have’ spending amid higher gasoline prices,” BofA Institute economists Joe Wadford and David Michael Tinsley wrote in the report.

Rent and tax relief offset by gas prices

The engine behind the surge? Rent relief. In Bank of America’s aggregated card and deposit data, median rent payment growth for Gen Z and Millennials slowed sharply in the 12 months through February 2026. And crucially, wages have been growing faster than rents for both generations — up roughly 9% year-over-year for Gen Z and 5% for Millennials. That gap between rent and wages is the financial breathing room younger Americans hadn’t had in years, and proprietary BofA card data shows they were spending it: on clothing, on dining out, and especially on electronics, which saw the sharpest discretionary jump of any category.​

Tax refunds added extra fuel early in the year. But economists at the BofA Institute stressed that most of the improvement reflects something more structural: younger renters, who make up a disproportionately large share of Gen Z and Millennial households, were finally catching a break after years of rent outpacing everything. Unlike Gen X and Baby Boomers, who are more likely to own their homes, younger generations live and die by the rental market — and for a stretch, that market was suffocating them.​

Now, rising gasoline prices threaten to claw back those gains. The average national gas price is up approximately 26% year-over-year as of March 23, driven by escalating conflict in Iran, according to American Automobile Association data cited in the report. And Gen Z, the analysis warns, is the generation most exposed.​

Even before this spike, Gen Z’s gasoline spending as a share of total card spending was running higher than any other generation’s — and had stayed stubbornly elevated while older generations’ shares fell from pre-pandemic levels. BofA economists attribute this to a straightforward reality: Gen Z is just entering the workforce, commuting for the first time, and doing so on relatively modest incomes. The ratio of gas spending to discretionary spending is highest for Gen Z of any cohort. In plain terms, for every dollar a Gen Zer spends on things they want, a larger share of it now goes to the pump than for a Boomer or a Gen Xer.​

The next wild card

The labor market adds another layer of risk. Young workers aged 22-27 — including recent college graduates — are already experiencing unemployment rates markedly above the national average, according to data from the Federal Reserve Bank of New York. Many work in retail and leisure, the very sectors most likely to feel the pinch from a pullback in discretionary consumer spending, which would, in turn, eliminate the jobs those same young people hold. It’s a feedback loop that could hit Gen Z from both ends of the ledger: higher costs at the pump and fewer hours at work.​

The wild card, BofA says, is whether rent growth continues to cool. If it does, younger consumers may have enough cushion to absorb some of the pain from gas prices. If rents start climbing again alongside fuel costs, the brief, hard-won spending revival that defined the past several months could stall just as it was getting started.
