K-Shaped Spending: America's Consumer Divide Widens

Fresh data reveals a deepening K-shaped spending trend in the United States, with the wealthiest 10% spending nearly as much on nonessentials as the bottom 70% combined, reshaping the corporate landscape and economic outlook.

Lead

The United States consumer economy is bifurcating at a pace not seen in the post-pandemic era. Moody's Analytics, the Federal Reserve, and Bank of America data collectively show that the top 10% of American earners account for nearly half of all consumer outlays — their discretionary spending alone rivaling the combined nonessential purchases of the bottom 70%. The split defines a K-shaped spending trend that economists and policymakers are watching as a structural risk to long-run growth sustainability.

What the Data Shows

The divergence between top 10% vs bottom 70% is most visible in discretionary categories. Spending by the top decile grew 62% between the third quarter of 2020 and the third quarter of 2025, a pace that outstripped every other income cohort. In the second quarter of 2025, that cohort accounted for approximately 49% of total US consumer spending.

The Federal Reserve's Distributional Financial Accounts show the top 20% of earners holding 87% of the wealth generated by individually owned stocks and controlling more than half of aggregate U.S. home value. The bottom 20%, by contrast, own just 3% of residential real estate. Total U.S. household net worth reached $183 trillion in the first quarter of 2026 — a record — yet the aggregate masks a concentration dynamic: the top 20% held approximately 72% of total household wealth as of the fourth quarter of 2025.

Bank of America card data captures the other end of the distribution. Spending by the lower third of cardholders contracted in mid-2025 and remained nearly flat through early 2026. The gap in nominal growth is running at roughly 1.5 percentage points annually — top earners above 4%, the broader population near 3% — a differential that compounds materially over time.

Luxury vs. Staple Spending: The Clearest Signal

The luxury vs. staple spending divergence is where US consumer inequality is most commercially visible. Higher-income households recorded spending growth in the 5%–10% range since the start of 2025. Premium travel, upscale dining, and experiential categories are direct beneficiaries: premium hotel demand rose approximately 7% year-over-year in the most recent quarter.

Meanwhile, budget-constrained households are trading down across categories — from groceries and household goods to personal care and over-the-counter healthcare. As of May 2026, 41.9% of consumers plan to spend more on food over the next six months, the first time that sub-category has crossed the 40% threshold since data collection began. The reading reflects compulsion rather than preference: rising food costs are forcing a larger share of wallet toward essentials.

This dynamic is reshaping retail strategy. Companies serving affluent customers are posting stable or rising volumes; those competing for middle- and lower-income wallet share are leaning on price promotion to defend unit sales. Thirteen percent more low-income consumers are switching brands versus peers earning above $100,000 annually.

Even within the luxury segment, the picture is nuanced. Morgan Stanley revised its personal luxury goods growth forecast for 2026 down to 2.5% from a prior projection of 4%–5%, signaling that the upward leg of the K is also moderating.

Structural Drivers of Economic Disparity

The structural roots of economic disparity run through asset markets and wage dynamics. Equity and real estate gains of the past five years disproportionately accrued to higher-income households, amplifying the wealth effect for the top quintile while leaving lower-income cohorts more exposed to inflation-driven erosion of real wages. Three-quarters of the incremental consumer spending generated by the post-2023 stock market rally came from the top 20% of earners, adding an estimated $53 billion in annual outlays — roughly one-seventh of the most recent quarter's annualized GDP growth contribution.

The New York Federal Reserve's retail spending analysis notes that income-based divergence at the product category level is less uniform than aggregate figures suggest, with growth rates across income deciles occasionally tracking in parallel. The Minneapolis Federal Reserve's 2026 review similarly cautions that competing measurement methodologies can produce divergent readings of the same underlying trend. What is not contested is the concentration of asset ownership and the widening gap in financial resilience across cohorts.

Policy Dimension

The policy environment is likely to compound the K-shaped spending trend. The One Big Beautiful Bill Act extends and expands individual income tax reductions weighted toward higher-income households while reductions in federal program funding are expected to constrain disposable incomes at the lower end of the distribution. TD Economics projects that these policy shifts will further entrench income-segmented spending behavior through at least the end of the fiscal year.

Outlook

The K-shaped spending divide has moved from a post-pandemic observation to a structural feature of the US consumer economy. The wealth-effect mechanism is sustaining aggregate spending data at levels that mask underlying stress in the bottom 70%, while fiscal policy tilts the balance further toward higher-income households. Corporations serving affluent consumers retain a structural tailwind; those competing for middle- and lower-income wallet share face a tightening demand environment. The durability of top-end spending remains contingent on equity and housing valuations — any sustained correction in asset prices would remove the primary support column of the upward leg of the K.
