Bank of America Says America's Economy Has Gone From K-Shaped to E-Shaped, and the Middle Class Is Now Falling Behind on Its Own

For two years, economists described America's economic recovery with a single letter: K. The wealthy soared upward on rising asset prices and resilient spending. The lower-income half of the country slid downward under the weight of inflation, stagnant wages, and mounting debt. It was a clean, if troubling, metaphor.

That metaphor is now outdated. Bank of America's latest consumer spending data, drawn from the transactions of tens of millions of cardholders, reveals a more nuanced and arguably more alarming picture. The economy is no longer splitting in two. It is splitting in three.

Welcome to the E-Shaped Economy

If the K described two diverging paths, the E describes three. Higher-income households continue trending upward. Lower-income households continue sliding down. But the middle class, long grouped with the lower half as "everyone else," is now carving out its own trajectory: not thriving, but not collapsing. Stuck in a limbo that is distinct from both the affluence at the top and the acute stress at the bottom.

The numbers make the three tiers stark. In January 2026, credit and debit card spending among higher-income households grew 2.5% year over year. Middle-income household spending grew modestly. Lower-income household spending grew just 0.3%, barely keeping pace with inflation and effectively flat in real terms.

The wage gap tells the same story from a different angle. The difference between higher-income and middle-income wage growth widened to its largest margin in nearly five years as of January. For the first time since the recovery began, the middle class is measurably falling behind the top, not just the bottom.

Half of All Spending Now Comes From the Top 10%

The spending concentration at the top of the income distribution has reached levels that would have been considered extreme even a decade ago. The top 20% of earners accounted for 59% of all consumer spending in the third quarter of 2025. More striking still, the top 10% alone now drive roughly half of all spending in the United States.

That concentration creates a strange kind of economic resilience. As long as wealthy Americans keep spending, and they are, buoyed by record stock prices, rising home equity, and largely insulated from tariff-driven price increases, aggregate consumer spending numbers look healthy. Total card spending rose 2.6% year over year in January, the strongest pace in nearly two years.

But strip out the top quintile and the picture collapses. The bottom 80% of American households are either spending less in real terms, financing purchases with debt at record interest rates, or both.

The Rent Trap and the Grocery Squeeze

Housing costs are the primary mechanism through which the E-shape is being carved. For roughly a quarter of lower- and middle-income households, a notable jump from the 20% share recorded in 2019, rent now swallows more than half of their annual income. That leaves almost nothing for discretionary spending, savings, or the kind of consumption that drives economic growth.

The grocery aisle has become the other pressure point. While headline inflation has moderated, food prices remain stubbornly elevated compared to pre-pandemic levels. Lower-income shoppers are not just trading down to store brands. They are buying less food. Middle-income households are trading down but maintaining volume, a subtle but meaningful distinction that shows up clearly in Bank of America's transaction data.

Meanwhile, wealthy households are not trading down at all. Their spending on travel, dining, and experiences has returned to levels that exceed 2019 by double-digit percentages.

Why It Matters More Than the K

The K-shaped economy was politically powerful but economically simple: two Americas, one doing well and one not. The E-shape is harder to address because it reveals that "the middle" is not actually in the middle of anything. Middle-income households are closer to the bottom tier in their financial stress than they are to the top, but different enough in their behaviors and options that the same policy responses will not work for both.

Tax cuts, for instance, disproportionately benefit the higher end of the income distribution, which is exactly what the One Big Beautiful Bill Act is expected to do when its provisions take full effect later this year. Direct aid programs help the lowest-income households but often exclude the middle class, which earns too much to qualify but too little to comfortably absorb $5-a-dozen eggs and $2,200-a-month rent.

The Consumer Economy Is Now a Story of Three Americas

For investors, the E-shaped economy explains a paradox that has confused markets for months: how consumer spending can remain "strong" in aggregate while retailers that serve middle-income shoppers post declining comparable sales. The answer is that "the consumer" is not one thing. It is at least three things, and the two smaller tiers are growing while the largest tier stagnates.

For workers and families in the middle tier, the message from the data is both validating and unsettling. The financial squeeze they feel is not imaginary, and it is not identical to what lower-income households face. It is a distinct form of falling behind: slow, quiet, and largely invisible in the headline numbers that policymakers use to declare the economy healthy.

Bank of America's analysts did not coin the term "E-shaped economy" to be clever with letters. They did it because the data demanded a new shape. And new shapes, in economics, tend to arrive only when old frameworks stop working.
