• The S&P Global US Composite PMI rose to 55.4 in August, marking its highest level since the start of the year and signaling robust, broad-based economic expansion.
  • The Manufacturing PMI surged to 53.3, a significant rebound from July's contractionary reading of 49.5 and well above the consensus estimate of 49.5.
  • The Services PMI remained firmly in growth territory at 55.4, exceeding expectations of 54.2 and underscoring the continued strength of the dominant service sector.

US private sector business activity accelerated at its fastest pace this year in August, according to the latest S&P Global PMI data, defying concerns that new tariffs implemented at the start of the month would stifle growth. The data, which surprised to the upside across all major indices, suggests the underlying economy remains remarkably resilient.

The manufacturing sector's sharp rebound is particularly noteworthy. After contracting in July, the factory PMI jumped to 53.3, a reading that indicates clear expansion. This resurgence was driven by a renewed increase in new orders and a solid uptick in hiring, marking a significant reversal from the previous month's slowdown. The services sector, which accounts for the bulk of US economic output, continued its strong run, with the PMI climbing to 55.4.

Price pressures remain a key focus for analysts and Federal Reserve officials. The report noted that input cost inflation eased slightly from July's recent peak but remains elevated, partly linked to higher import costs following the latest tariff rounds. Firms continued to pass these costs on to customers, though the rate of output charge inflation moderated. This persistent inflationary pressure complicates the timeline for potential interest rate cuts.

Employment trends provided another bright spot. Service providers increased their staffing levels at the fastest pace since January, and manufacturers also resumed hiring after a period of caution. This robust job creation within the private sector points to sustained confidence among business owners about near-term demand, even as the survey indicated that overall business confidence had eased from earlier in the year.

The strength of the domestic economy is helping to offset reported declines in foreign demand for US services, a trend some economists attribute to retaliatory trade measures. The data suggests the US is on track to be a relative outperformer among developed economies in the third quarter, though the longer-term outlook remains clouded by ongoing trade policy uncertainty.
