(Bloomberg) -- Growth in the US service sector moderated in September as a measure of new orders slid to the lowest level this year.

The Institute for Supply Management’s overall gauge of services fell by nearly a point to 53.6, data out Wednesday showed. Readings above 50 indicate expansion, and the September figure was in line with the median estimate in a Bloomberg survey of economists.

While growth in business activity quickened to a three-month high, an almost six-point drop in orders suggests demand for services may be starting to weaken. In August, the measure of bookings reached a six-month high.

The gauge of business activity index, which parallels the ISM factory production index, rose 1.5 points to 58.8. The services sector has been a bright spot for the economy as Americans rotate their spending from goods back to experiences.

About 34% of respondents reported higher business activity in September, the biggest share since April 2022.

“The majority of respondents remain positive about business conditions; moreover, some respondents indicated concern about potential headwinds,” Anthony Nieves, chair of the ISM Services Business Survey Committee, said in a statement.

Still, some consumers are already growing more discerning in their services spending amid higher financing costs, stubborn inflation and smaller wage gains. New challenges, including the resumption of student-loan payments this month, also pose a risk to discretionary purchases of services as well as goods.

Thirteen services industries reported growth in September, including real estate, retail trade and mining, the ISM report showed. Five reported a decline, led by agriculture, entertainment and recreation, and accommodation and food services.

The report also showed more moderate growth in hiring last month. Government figures due Friday will provide further clues into the direction the job market. Economists say employers probably added jobs at a healthy pace in September.

Prices paid for inputs continued to rise, matching the fastest pace since April. A metric of supplier deliveries, meantime, rose above 50 for the first time since November, indicating delivery times lengthened.

The ISM measure of inventories at service providers moderated, and a gauge of sentiment about inventory levels also fell to a three-month low.
