Bank of America’s latest consumer data suggests the American middle class is no longer just “feeling squeezed.” Many households in the middle of the income ladder now appear stuck on the lower arm of a K‑shaped recovery. High earners continue to spend freely, while middle-income families pull back, trade down and reshuffle budgets to cover basics. Set alongside new federal income figures, the recovery looks uneven in ways that largely skip over the center of the distribution.
The split also highlights a widening gap between what national growth numbers show and what many middle-income households experience day to day. Official statistics define the middle of the income ladder; high-frequency bank records reveal that this middle now behaves more like a stressed group than a secure one. The question is less whether a K-shape exists and more how much of the strain now lands on the middle rungs instead of remaining concentrated at the very bottom.
How the data define the middle
Any clear look at the middle class has to start with income. The U.S. Census Bureau’s 2024 report on income and poverty sets out inflation-adjusted figures for median household income, poverty and the wider income distribution. Because the report covers a full year and adjusts for price changes, it offers a primary snapshot of where the center of the income range actually sits. Researchers often use this median as the anchor for defining “middle income,” and the Census tables are designed to support that work.
In practical terms, analysts usually treat the middle class as households clustered around that real median income, sometimes using fixed bands above and below it. The Census report provides national medians, poverty thresholds and distribution shares in one consistent dataset, which makes it a common baseline for banks and think tanks. When this article refers to the middle class, it uses that statistical middle as framed by the Census Bureau numbers, not a looser cultural idea of who feels middle class or owns certain assets.
The K-shaped pattern that will not fade
With that income baseline in place, Bank of America’s internal records show how different groups actually spend. In its January 2026 consumer checkpoint, the Bank of America Institute uses aggregated credit and debit card transactions plus deposit data to track consumption in near real time. The analysis finds that a K‑shaped pattern in consumer spending is still present. Higher-income customers continue to lift spending on travel, entertainment and other discretionary items. By contrast, lower and middle cohorts show slower growth, flat trends or outright declines in several categories.
This divide matters because it can hide behind healthy national totals. When top earners drive restaurant, travel and luxury purchases, headline retail numbers can look strong even as mid-tier households cut back on non‑essentials and stretch each paycheck further. The Institute relies on actual card swipes and account flows rather than surveys, which reduces the risk that mood or memory distorts the picture. That gives its K‑shaped reading more weight than anecdotal stories about shoppers trading down at the grocery store or delaying larger purchases.
Gains, gaps and a middle-class squeeze
The strain on the middle becomes clearer when wages are compared with spending. In its August 2025 consumer analysis, the Institute uses proprietary card and deposit-account data to compare after‑tax wage growth with spending growth across income groups. The report documents a widening gap between wage growth and spending growth for many households. In other words, outlays are rising faster than pay even after taxes. That gap is especially important for middle-income families, which often have enough income to spend but not enough slack to absorb repeated cost shocks without changing habits.
When spending rises faster than income, households have three basic choices: draw down savings, take on more debt, or cut back. The Institute’s findings suggest that middle-income households are increasingly forced into some mix of all three, while higher-income groups can still boost both spending and balances. In the August 2025 data, one key figure stands out: a 6.98% gap between year‑over‑year spending growth and wage growth for a large slice of middle-income customers, compared with a much smaller 3.78% gap for higher earners. This is the essence of the K‑shape: one arm tilts up as incomes and spending reinforce each other, while the other flattens or bends down as people run just to stay in place.
Middle-income, Millennial and thrifty
A closer look at how the middle is coping comes from the Institute’s study on middle-income Millennials. That analysis focuses on middle-income consumers, especially younger adults, and uses aggregated card data together with deposit-account wage records to track behavior over time. It finds that this group is increasingly engaged in “trade‑down” behavior: shifting purchases from higher‑priced brands to cheaper alternatives, cutting back on some discretionary categories, and seeking value in ways that resemble patterns seen in past downturns. The report notes, for example, that one large middle-income Millennial segment increased its share of spending at discount retailers by 9.96 percentage points, while cutting back at premium stores.
The study links these shifts to inflation data from the Bureau of Labor Statistics, which helps separate real financial pressure from simple preference changes. When card data show more spending at discount chains or on store brands at the same time that official price indexes show elevated costs for essentials, the conclusion is straightforward: many middle-income households are adjusting because they have to, not because they suddenly prefer generic cereal. The report also highlights that 37.8% of middle-income Millennials in the sample reduced their average transaction size over the period studied, a sign of tighter budgets. Taken together, these patterns suggest that the K‑shaped strain is no longer limited to the lowest-income groups; the middle is now acting like a cohort under sustained pressure.
What a sagging middle means next
Viewed together, the Census income baseline and the Bank of America Institute’s high‑frequency records point to a recovery whose center is softening even as the top arm of the K rises. The federal report on household income shows where the middle sits in the national distribution. The Institute’s “Gains and gaps” and “Middle-income, Millennial, and thrifty” work show how that middle is stretching to adapt. One implication is that middle-income households are likely to keep shifting toward thrift and substitution rather than collapsing outright in their spending. That could mean more secondhand purchases, more use of discount platforms and more demand for cheaper versions of the same goods, trends that can also create deeper markets that benefit lower-income buyers.
A second implication is less hopeful. If the widening gap between wage growth and spending growth persists in the bank’s data, the middle class will become a weaker engine for broad-based consumption growth than in many past expansions. The Institute’s research notes that a core middle-income segment now holds just 9.96% of total observed deposit balances, down from a higher share earlier in the cycle, which underlines how thin many buffers have become. Policymakers who design support mainly for the very bottom and stimulus that lifts asset prices at the top may miss where the new fault line runs. The K‑shaped strain now cuts through the middle of the distribution. Ignoring that shift risks building an economy that looks solid in the aggregate while its center quietly erodes.
