Reversal of K-Shaped Spending Trends in the US Economy

For over a year now, the phrase “K-shaped recovery” has been a kind of economic shorthand, a way to describe an uncomfortable reality. It’s the notion that the economic experience of the last few years has split the population like the diverging arms of the letter K. One arm points up, representing higher-income households who have largely weathered inflation, seen their wealth in homes and portfolios grow, and continued to spend freely. The other points down, symbolizing lower-income households squeezed by rising costs, depleting savings, and a labor market that feels increasingly unforgiving. This divergence explains how headline economic data could appear robust while sentiment on the ground remained so grim, a dissonance many journalists, myself included, have grappled with in our reporting.

But data out this week suggests those lines may be starting to converge. Bank of America economists noted a striking reversal in their internal card spending data. Excluding volatile gasoline purchases, annual growth in spending by lower-income households has now outpaced that of higher-income households for two consecutive weeks. “This is a reversal of the K-shaped spending dynamics that have characterized consumer spending for over a year,” wrote Aditya Bhave, a Bank of America economist, in a research note I reviewed. It’s a small shift in a vast ocean of data, but in my years covering consumer behavior, these early tremors often signal a broader change in the economic weather.

Several factors could be driving this nascent catch-up:

• Historically tight labor market
• Notably strong wage growth for lower-wage workers
• A temporary dip in gas prices in June
• Changes in tax withholding from last year’s legislative changes
• Increased confidence in discretionary spending
• Elevated spending potential for lower-income households

However, declaring the death of the K-shape is premature. The trend is more nuanced than a simple reversal. Mark Mathews, chief economist at the National Retail Federation, observed in his own analysis that while lower-income spending growth has turned positive compared to last year’s declines, higher-income households are still responsible for the bulk of absolute spending growth. “Lower spenders aren’t that far behind,” he noted, but the gap persists. My conversations with retail analysts suggest this is a story of degrees, not a complete plot rewrite. The discretionary spending surge—where outlays on non-essentials outpace staples across most income groups, as noted by the NRF—indicates a baseline of confidence. Yet for those on the lower arm of the K, that confidence is fragile and contingent.

The most significant threats to this fragile convergence are immediate and visceral: inflation and policy shifts. Lower-income consumers allocate a far larger share of their budget to necessities like food, energy, and housing. As Nancy Vanden Houten, lead U.S. economist at Oxford Economics, warned in a recent report, the reinstatement of stricter work requirements for federal food assistance programs is having a tangible impact. “Cuts in SNAP benefits spill over into other categories,” she wrote, with spending on clothing, restaurants, and household goods most vulnerable. When your grocery budget is cut, you don’t just eat less; you stop going out to dinner altogether. This is the kind of secondary effect that can deepen K-shaped dynamics even as other data points suggest improvement.

Similarly, the recent climb in gasoline prices acts as a direct tax on mobility and disposable income. For a professional commuting from Westchester to Manhattan, a fifty-cent jump per gallon is an annoyance. For a service worker driving thirty miles each way to their job in a suburban warehouse district, it can be the difference between making a credit card payment or not. This sensitivity means the recent lower-income spending bounce could prove ephemeral if energy costs remain elevated into the fall.

What we are witnessing, I believe, is not the end of the K-shaped economy but its evolution. The pressures that created it—a pandemic that accelerated wealth inequality, inflation that hit essentials hardest, a policy landscape in flux—have not vanished. The data from Bank of America and the NRF shows the lower arm of the K is trying to lift itself, buoyed by a strong job market and maybe a temporary fiscal nudge. But its trajectory remains precarious, vulnerable to the next spike at the pump or cut to a social safety net program.

The real test will come later this year, as we move beyond summer and into a holiday season that will be a critical gauge of consumer health. Will the lower-income spending momentum hold, allowing for a more balanced, less bifurcated recovery? Or will the structural pressures reassert themselves, widening the gap once more? As a business journalist, my job is to track the data, but also to understand the human calculus behind it. For millions of Americans, that calculus is currently being done at the kitchen table, with a calculator in one hand and a gas station receipt in the other. The direction of that lower arm of the K depends on which number wins out.
