US retail sales recorded their largest monthly increase in five months, with broad-based growth signaling that consumers continue to spend despite rising gasoline prices and shrinking real wages, supported by robust equity markets and a stable job market.

Data released Wednesday showed retail sales climbed 1.2% month-over-month in August, significantly surpassing the 0.8% increase economists had widely anticipated. July's figure was revised to a 0.5% decline. Among the 13 retail categories covered in the report, 12 posted gains, including gas stations and online retailers.

Back-to-school shopping likely boosted department store spending while also driving consumption in clothing, sporting goods, and electronics. The so-called "control group" sales measure, which feeds directly into the government's calculation of goods spending within gross domestic product, rose 1.4%—the largest advance in nearly two years. This metric excludes food services, auto dealers, building materials stores, and gas stations.

Non-store retailer sales, primarily reflecting online shopping, increased 2.6% in August, marking the strongest gain since February 2025 after a decline in the prior month. This year, Amazon (NASDAQ: AMZN) moved its Prime Day promotional event from July to June, a timing shift that may have distorted the data and weighed on July's overall retail figures.

Gas station sales rose 3.1%. According to AAA data, the national average gasoline price remained above $4 per gallon through the end of August. Fuel costs have climbed further this month, surpassing $4.30 per gallon, as conflicts in the Middle East and Ukraine constrained supply.

The retail report also indicated a 0.6% increase in sales at motor vehicle and parts dealers. Industry data released earlier this month showed auto sales in August reached their strongest level since April 2025. Excluding autos and gasoline, retail sales also advanced 1.2%.

Restaurant and bar revenues posted a solid 1.2% gain, representing the only services category within the retail report. Since consumption accounts for roughly 70% of US GDP, retail sales figures serve as a critical indicator for investors assessing the state of the economy and the trajectory of monetary policy.

The latest retail sales data arrives as the Federal Reserve considers raising interest rates to curb inflation, which has remained above the central bank's target for more than five consecutive years. At 2:00 AM Beijing time Thursday, the Fed will announce its rate decision alongside updated economic projections. Half an hour later, Fed Chair Warsh will hold a press conference.

Just one month ago, market pricing implied only a 33.1% probability of a rate hike this meeting. That figure now stands near 95%, with market expectations nearly unanimous. Should the Fed follow through, it would mark the first rate increase in more than three years.

US consumer spending has demonstrated resilience throughout the year, underpinning overall economic growth. While the boost from tax refunds has faded, low unemployment and rising stock prices continue to support household finances. Meanwhile, retailers are seeking ways to attract increasingly price-conscious consumers.

Walmart (NYSE: WMT) announced last month that it had cut prices on thousands of items, partially funded by tariff rebates. Nevertheless, many Americans continue to face cost-of-living pressures as wage growth fails to keep pace with rising prices. Inflation-adjusted average hourly earnings declined for the fifth consecutive month in August compared with a year earlier.
