US consumers are still opening their wallets.

Retail and food service sales rose 1.2% in August to $773.9bn, rebounding from a revised 0.5% decline in July and comfortably exceeding economists’ expectations. Sales were 6% higher than a year earlier.

But for retailers, the headline number tells only part of the story.

The August figures point to a consumer who remains willing to spend, while showing why category, channel and price point matter increasingly to retailers.

Non-store retail sales rose 2.6% during the month, electronics and appliance sales increased 1.6%, and food services and drinking places gained 1.2%.

Elsewhere, the picture was weaker. Department-store sales fell 0.8%, while building-material and garden-equipment sales declined 0.2%.

One month of category movements is not enough to establish a lasting shift in consumer behaviour. But the differences across categories show how strong aggregate retail growth can conceal very different conditions across the industry.

Strong sales, with an important qualification

August’s rebound was stronger than expected.

Economists polled by Reuters had forecast a 0.8% monthly increase. Retail sales excluding automobiles, petrol, building materials and food services – a measure often used to gauge underlying consumer demand – rose 1.4%, compared with expectations for a 0.4% increase.

That suggests August’s strength extended well beyond higher spending at petrol stations.

But there is an important qualification.

The Census Bureau’s retail figures are adjusted for seasonal variation but not for changes in prices.

A 6% year-on-year increase in retail sales therefore does not mean Americans bought 6% more goods and services. Some of the increase reflects higher prices.

Petrol-station receipts, for example, can rise because fuel prices increase even if the volume of fuel sold does not.

For retailers, nominal sales growth is encouraging. But the volume of goods sold – and the margin generated from those sales – ultimately matters more than the headline dollar figure.

A more selective consumer

There is little in the August data to suggest that Americans have broadly stopped buying discretionary goods.

Electronics and appliance stores recorded a 1.6% monthly increase, restaurants and bars gained 1.2%, and back-to-school shopping helped support spending elsewhere.

But continued spending does not mean household budgets are under no pressure.

As inflation squeezes purchasing power, consumers can become more selective without reducing their overall spending dramatically.

They can trade down to cheaper products, switch brands, wait for promotions or postpone purchases they consider less urgent. Aggregate spending can therefore remain healthy while changes in product mix put pressure on pricing power and margins.

The effect is also unlikely to be evenly distributed.

Lower-income households generally have less capacity to absorb increases in food, energy and fuel costs. Higher-income consumers tend to have greater financial buffers and can continue to support overall spending.

The result is a retail market in which a strong national sales number can coexist with greater pressure in particular customer groups and categories.

Online retail stands out

One of August’s strongest category performances came from non-store retailers, where sales rose 2.6%.

The timing matters. Major online promotions and back-to-school shopping contributed to activity during the period, so one month does not establish a lasting shift towards digital channels.

Nevertheless, the increase highlights the importance of online retail in an increasingly value-conscious consumer environment.

Digital channels make it easier for shoppers to compare prices, search for promotions and move between competing brands and retailers.

That does not necessarily mean consumers spend less. Instead, greater price transparency can influence where spending goes – and make competition for each dollar more intense.

For retailers, that creates a potential paradox: demand remains resilient, but capturing it profitably can become harder.

Not every discretionary purchase is equal

August also illustrates why the label “discretionary spending” can conceal important differences.

Consumers may continue eating out, buying clothing for the new school year or replacing an electronic product while postponing a home improvement project or another large purchase.

Building-material and garden-equipment sales declined 0.2% in August even as several other discretionary categories expanded.

The divergence does not by itself establish a trend. But it demonstrates why retailers need to look beyond total consumer spending.

The willingness to make a $50 purchase does not necessarily tell retailers much about the willingness to make a $500 or $5,000 purchase.

As household budgets come under pressure, urgency, price and the ability to postpone a purchase can become increasingly important determinants of demand.

What happens after back-to-school?

August also benefited from an important seasonal factor: the new school year.

Households increased purchases associated with back-to-school shopping, helping support categories including clothing and other goods.

That provided retailers with an important late-summer boost, but it also means August should not be read in isolation.

The more revealing test will come as seasonal purchasing and major promotional events fade.

If spending remains broad-based through the autumn, August will look more like evidence of durable consumer resilience.

If growth becomes increasingly concentrated in necessities, promotions or particular channels, it could point to consumers becoming more defensive even while continuing to spend.

Inflation makes the headline harder to read

The distinction between dollars spent and goods purchased is likely to remain important.

US import prices rose 0.7% in August and were 7% higher than a year earlier, adding to evidence of continued price pressure.

For retailers, inflation works in two directions.

Higher selling prices can lift reported revenue. But higher merchandise and operating costs can squeeze margins, while rising prices reduce consumers’ purchasing power.

A retailer can therefore report growing sales without experiencing an equivalent improvement in unit volumes or profitability.

That makes the quality of sales increasingly important.

What retailers should watch next

August gives retailers plenty of reasons for encouragement.

Consumers are still spending, underlying sales measures were strong and several discretionary categories continued to grow.

But the next phase will be less about whether total retail sales remain positive and more about what sits underneath them.

The first thing to watch is mix. If consumers increasingly trade down or shift towards lower-priced products, revenue can remain resilient while margins come under pressure.

The second is promotional intensity. A consumer who waits for discounts is still a consumer, but potentially a less profitable one.

The third is category divergence. Larger and more easily postponed purchases could weaken before everyday spending does, creating sharply different conditions across the retail sector.

These indicators may reveal changes in household behaviour before they become obvious in the headline retail-sales figure.

Resilient does not mean unchanged

August does not show an American consumer retreating from the shops.

Retail sales rebounded sharply and underlying spending was stronger than expected.

But the figures are more useful when viewed as a picture of changing consumer behaviour than simply as a measure of consumer strength.

Americans are still spending. Yet higher prices, differences in household finances, seasonal purchasing and value-seeking behaviour mean where those dollars go matters more.

For retailers, the key question is therefore shifting.

It is not simply whether consumers keep spending.

It is what they buy, where they buy it and how much persuasion – or discounting – is required to win the sale.
