Consumer spending slowdown: what cools the economy's biggest engine

Personal consumption expenditures—the economic term for what consumers buy—account for roughly 68% of U.S. gross domestic product. When Americans spend, businesses hire, invest and expand. When they pull back, economic growth slows or stalls. This central role makes consumer spending both the most reliable driver of growth and the economy's most vulnerable pressure point.

In 2026, that vulnerability is showing. Consumer confidence fell to a two-year low in August, with measures of future expectations sinking below historically recessionary thresholds. Spending growth is decelerating sharply, from 3.6% in late 2024 to a projected 1.5% for the full year. Multiple forces are working to discourage purchases: job losses, rising everyday expenses that consume larger portions of household budgets, elevated credit card interest rates, and persistent inflation in essential categories. Understanding what triggers these pullbacks—and how they ripple through the economy—explains why economists watch consumer behavior so closely.

Consumer spending: the foundation of two-thirds of economic output

The Bureau of Economic Analysis tracks personal consumption expenditures monthly and quarterly as part of its GDP accounting. This concentration means the economy is heavily dependent on a single source of demand: household purchases of goods and services. When that engine runs strong, the entire economy accelerates. When it sputters, growth falls below potential.

The scale of consumer spending is enormous. July 2026 retail sales totaled $763.6 billion, up 5.0% from July 2025. Monthly retail sales currently average $733 billion or more. Yet these headline figures mask an important shift happening beneath the surface: growth rates are slowing dramatically. Real consumer spending growth—adjusted for inflation—is projected to decelerate to roughly 1.5% annually in 2026, down from the faster pace of prior years. That 2.1 percentage point drop from late 2024's 3.6% growth rate signals reduced momentum heading into the final months of the year and suggests that the consumer engine is losing horsepower.

Confidence has cracked and consumer sentiment is deteriorating

This sentiment shift reflects real pressures on household finances. Job losses have accelerated, with the economy shedding 23,000 positions in July 2026 alone. The leisure and hospitality sector has contracted, eliminating 40,000 jobs—a sector that historically signals broader consumer weakness when it softens because restaurants and hotels depend entirely on discretionary consumer spending. Younger workers and lower-income households report heightened anxiety about unemployment, with Gen Z consumers nearly ten times more likely than baby boomers to rank unemployment as their top concern. Deloitte found in October 2025 that shoppers across income brackets and generations planned to curtail spending, and that sentiment hardened through 2026. Circana's March 2026 analysis revealed the income dynamics have shifted from a K-shaped economy (where high earners outpaced others) to what researchers describe as a dipping E-shape, where even higher-income consumer growth is slowing and middle-income households are actively reducing discretionary purchases.

Essential costs are squeezing discretionary purchasing power across income levels

Consumers spend less on wants when they pay more for needs. In 2026, rising costs for healthcare, childcare, utilities and property taxes have consumed larger portions of household budgets. Stanford's analysis projects that health insurance premiums will roughly double for 20 million Americans in 2026, while electricity prices, which nearly doubled in California since 2019, continue rising nationally. Uninsured consumers face particular strain from elevated deductibles and copays. Tariffs alone are estimated to increase the average household's cost of living by approximately $2,500 annually if sustained at current levels, according to TD Economics.

Meanwhile, wage growth has cooled. Inflation-adjusted disposable income growth is expected to slow to just 1.1% year-over-year by mid-2026, down from 2% a year earlier. Core inflation is anticipated to persist above 3% through mid-2026, with core goods prices climbing steadily, peaking at about 4 to 5% year-over-year by mid-year. These overlapping pressures mean real purchasing power is contracting even as nominal incomes grow.

This squeeze is visible in retailer data and shopping patterns. Dollar General and Dollar Tree have attracted higher-income customers throughout 2025 and 2026, a shift that signals value-seeking behavior across income brackets rather than concentrated in lower-income households alone. Warehouse clubs and discount retailers have captured market share from traditional department stores. Consumers report being hungry for value and discounts, with 28% of consumers actively trading down to discount retailers—a phrase that translates as: purchasing power has tightened significantly and households are making more intentional, rational decisions about every purchase.

How interest rates flow through to reduced consumer spending

The relationship between interest rates and spending is direct and measurable. Most credit cards carry variable rates tied to the prime rate, which equals the Federal Reserve's federal funds rate plus approximately 3 percentage points. Banks then add their own margin based on a cardholder's creditworthiness. According to Federal Reserve supervisory data covering approximately 80% of active U.S. credit card accounts from 2016 through 2025, when a credit card APR rises by 1 percentage point, consumers reduce spending by an average of 8.7% the following month—roughly $74 less in monthly purchases per account. However, this effect is not uniform. Consumers who carry balances from month to month reduce spending by approximately 15% per percentage point increase. Consumers who pay their balance monthly show virtually no spending reduction because they pay no interest. The effect is sharpest among lower-credit-score cardholders, who reduce spending by approximately 18% per percentage point increase because they have fewer alternatives to paid credit and fewer financial resources to redirect toward other forms of debt reduction.

Structural headwinds are prolonging the slowdown

Beyond labor market softness and interest rates, broader forces are dampening consumer activity. The resumption of federal student loan repayment has redirected household cash flow away from discretionary purchases, affecting millions of borrowers simultaneously. Tighter immigration policy has constrained labor supply and raised uncertainty about future economic growth, affecting hiring plans and wage pressures. The housing market remains stagnant, preventing the wealth gains from appreciation that once encouraged spending among homeowners and supported construction employment.

These factors stack on one another rather than pulling in opposite directions. A consumer losing income from job losses cannot offset that by accessing cheaper credit when interest rates rise. A household managing higher healthcare costs cannot easily shift spending categories when utilities also increase. Stock market wealth effects, which contributed approximately $100 billion (or 0.4% of GDP) to economic growth in 2025 according to Stanford's analysis, may dissipate if equity prices stall. The combination of weaker employment, higher costs, and expensive credit creates a narrowing window for consumer purchases, particularly in categories like furniture, appliances and vehicles that households often finance through credit. Discretionary spending categories are likely to contract most sharply as households prioritize necessities over optional purchases.
