US retail sales reached $560.8bn in September, marking the twelfth consecutive monthly increase even as petrol prices squeezed household budgets. The figure excludes automobile dealers and petrol stations and comes from the CNBC/NRF Retail Monitor, powered by card-data firm Affinity Solutions and released by the National Retail Federation (NRF).

Sales rose 0.28% month over month and 4.05% year over year. That is an acceleration from August, which posted 0.22% and 3.87% gains respectively. The pickup is modest, not a breakout. Sourcing teams should read it as steady demand, not a surge requiring capacity bets.

How did apparel perform?

Clothing and accessories sales totalled $41.9bn in September. That is a 0.48% increase from August and 2.21% growth against September last year. Apparel is growing slower than the overall market, a gap of nearly two percentage points.

NRF president and CEO Matthew Shay said: "Retail sales rose again last month as consumers continued to spend following a solid back-to-school shopping season. Households remain budget conscious, concentrating on everyday essentials even as higher gasoline prices continue to absorb a larger share of family budgets."

The essentials tilt carries margin implications. Shay added: "Retailers continued to prioritise affordability, leaning on promotions and value pricing to keep everyday products within reach."

Promotional intensity means apparel vendors should expect continued pressure on unit prices and tighter order books on discretionary lines. The data does not break out full-price versus markdown volume. That omission matters.

What drove the headline number?

Core retail sales, which strip out restaurants, auto dealers and petrol stations, hit $453.1bn. That is up 0.27% month over month and 3.73% year over year. August core figures were weaker: 0.17% and 3.47%. Again, acceleration, but marginal.

Category performance was sharply mixed:

• Electronics and appliances led all sectors, up 8.41% year over year, defying the stated pivot toward essentials.
• Furniture and home furnishings was the only major sector to decline, falling 2.7% year over year.
• Clothing and accessories grew 2.21% year over year, below the market average.

The furniture decline confirms the big-ticket discretionary pullback. The electronics result complicates the "essentials only" narrative that Shay's comments sketch. Both cannot fully explain the other.

Why should supply-chain teams care about the methodology?

September marks the debut of an updated methodology for the CNBC/NRF Retail Monitor. The new approach draws on spending patterns from roughly 120 million debit and credit cards, adjusted to reflect US consumer demographics and aligned with US Census Bureau retail sales totals.

Card-panel data arrives faster than census surveys but carries its own bias. Cash purchases and some debit segments may be underrepresented. The NRF has an interest in a healthy retail narrative, and its commentary frames caution as resilience. Treat the direction as reliable and the precision of the second decimal place with some skepticism.

What comes next?

For apparel sourcing, the practical reading is flat-to-slow growth with promotion-dependent sell-through, which argues for conservative open-to-buy (the budget retailers set aside for new orders) and shorter, more reactive order cycles heading into holiday. If fuel prices keep absorbing household budgets, the essentials concentration Shay describes will likely persist through the fourth quarter.
