Walmart Posts Slowest Growth in Six Years as Retail Sales Tumble and Tax Refund Boost Fades

Walmart Inc. delivered a rare earnings miss on Tuesday that sent shockwaves through the retail sector and raised fresh concerns about the health of the American consumer. The world's largest retailer posted its slowest quarterly sales growth in six years, while government data released last week showed retail sales declined 0.6 percent in July — the steepest drop since May 2025.

The twin blows arrived at a critical moment for the U.S. economy. Resilient consumer spending had been the primary engine keeping GDP growth positive through the first half of 2026, even as inflation from the ongoing conflict with Iran weighed on household budgets. But the July retail sales report and Walmart's underwhelming results suggest that engine is starting to sputter.

"The question as we head later in the year is: What happens when those tax refunds start to deplete and diminish?" said John Mercer, a retail analyst at Coresight Research. "We're starting to see the answer."

Walmart's Slowest Growth Since 2020

Walmart reported fiscal second-quarter 2027 earnings on August 20, 2026, and the numbers were sobering. Comparable sales for the 13-week period ended July 31 came in below analyst expectations, marking the company's slowest U.S. growth rate in six years. The company's average transaction size increased just 1.1 percent, a sharp deceleration from the mid-single-digit gains Walmart had been posting throughout 2025.

Walmart did raise its full-year net sales growth forecast to 4-5 percent, and e-commerce sales surged 24 percent while its Walmart Connect advertising business posted 43 percent revenue growth. But those bright spots couldn't hide the fact that shoppers are pulling back on discretionary purchases and trading down to cheaper alternatives even within Walmart's aisles.

Walmart CEO Doug McMillon acknowledged the shift in a statement, noting that the company is seeing "a more cautious consumer" and that shoppers are "more selective" about what they buy. The retailer has responded by leaning harder into its value messaging and expanding its private-label offerings, a classic recession playbook.

Retail Sales Decline Confirms the Trend

Walmart's struggles didn't happen in a vacuum. On August 14, the U.S. Census Bureau reported that total retail and food services sales fell 0.6 percent in July to $763.6 billion, down from $768.1 billion in June. Economists had projected a modest 0.1 percent increase.

The decline was broad-based, with car dealerships, gas stations, and online merchants all posting lower sales. Excluding autos and gas — two volatile categories — core retail sales still fell 0.3 percent, signaling that the weakness wasn't limited to just one or two sectors.

Year-over-year, retail sales were up 5 percent, which sounds healthy until you account for inflation. The Commerce Department reported in late July that the U.S. economy expanded at just a 1.5 percent annualized rate in the second quarter, the slowest pace since early 2025, as inflation from the Iran conflict continued to weigh on growth.

The Tax Refund Effect

The retail slowdown has been months in the making, and it traces back to an unusual quirk of the 2026 tax season. Due to changes in IRS processing timelines and an early filing rush, millions of Americans received their tax refunds in February and March — earlier and larger than in typical years.

That windfall fueled a spending spree in the first half of 2026. Retailers enjoyed robust sales growth, the S&P 500 hit multiple record highs, and economists upgraded their GDP forecasts. But by July, the refund checks had been spent, and the underlying weakness in household finances started to show.

"Resilient consumer spending in the first half of 2026 was fueled by a robust tax refund season," John Mercer of Coresight Research told The New York Times. "Now we're seeing what happens when that artificial boost fades."

The data backs him up. According to PYMNTS Intelligence, July's retail sales decline reflected a "much more deliberate reset in household spending." Consumers are still buying — but in select categories, and only after working the budget first.

What Walmart and Target Earnings Tell Us

Walmart wasn't the only retailer to report disappointing results this week. Target is scheduled to release earnings on August 21, and analysts are bracing for a similar story: slowing sales growth, cautious consumers, and a shift toward value-oriented purchases.

The Walmart-Target earnings one-two punch has become a crucial economic indicator in recent years, offering a real-time snapshot of how middle-class and lower-income Americans are managing their budgets. Both retailers cater to a broad swath of the population, so when they struggle, it's a sign that the consumer economy is under stress.

Wall Street is paying attention. The S&P 500 snapped a three-day losing streak on Wednesday after the U.S. Treasury announced it was doubling its debt buyback program to steady the bond market, but retail stocks remained under pressure. Investors are now pricing in a higher probability that the Federal Reserve will hold interest rates steady or even cut them at its next meeting if consumer spending continues to weaken.

The Road Ahead

Retail sales data are subject to revisions, and monthly results can be affected by temporary factors like weather, promotional events, and gasoline price swings. But the consistency of the warning signs — from Walmart's slowest growth in six years to the worst retail sales decline in more than a year — suggests this isn't just noise.

The question now is whether the consumer slowdown is a temporary pause or the beginning of a more serious downturn. July's numbers suggest households are still willing to spend, but only on essentials and only when they can find a deal. That's good news for Walmart's value positioning, but bad news for the broader economy.

Target's earnings on August 21 will offer the next clue. If its results mirror Walmart's, it will confirm what the data is already telling us: the American consumer is tapped out, and the second half of 2026 is going to look a lot different than the first.
