The S&P Global US Services PMI rose to 58.8 in September 2026 from 56.5 in August, revised slightly up from the flash estimate of 58.7. The index has signalled sustained growth in business activity for six months, with the latest expansion the most pronounced since July 2021. New orders rose the most in over four years, as strong domestic demand outpaced the rate of increase in export orders. Workforce numbers increased for a third consecutive month, with job creation reaching its fastest rate since June 2022. Meanwhile, strong new orders continued to outpace capacity, leading to another solid increase in backlogged work and extending the run to 19 months.
