US economic expansion accelerated markedly during August, with the private sector reaching its strongest level of growth in 52 months, Action Forex reported. Flash purchasing managers' index data compiled by S&P Global revealed a robust pickup in underlying activity, driven by dynamic performance within the services industry that more than offset a moderation in factory output. According to figures detailed by ForexLive, the composite output index climbed to 56.0, rising from 54.5 in the prior month. The reading marked the fastest pace of expansion recorded in over four years.
The services sector emerged as the primary engine of the August improvement. Action Forex highlighted that the services business activity index advanced from 54.6 to 56.8, establishing a 20-month peak. ForexLive confirmed the services reading of 56.8, noting that the figure significantly exceeded market expectations of 54.0 and represented a substantial increase from the previous month's 54.6. The pronounced strength in services underpinned the overall composite gain, illustrating continued resilience across consumer-facing industries. Action Forex attributed the sharp upward revision in the composite index directly to this surge in services activity, which surpassed consensus forecasts by nearly three percentage points.
Conversely, manufacturing activity cooled relative to analyst projections. ForexLive reported that the flash estimate for the manufacturing PMI fell to 53.2, landing below the consensus forecast of 53.9. This represented a deceleration from the June reading of 53.9. Although the manufacturing segment registered a decline of seven-tenths of a point, the index remained elevated, indicating that output conditions continued to improve at a solid pace. The divergence between the resilient services data and the softer manufacturing print underscored uneven conditions across different segments of the domestic economy.
The convergence of data points indicated that total private-sector momentum intensified through the summer. While factory gate activity showed signs of easing, the breadth and depth of expansion in services ensured that aggregate growth rates pushed to their highest extent since mid-2021. The flash estimates suggest that underlying economic dynamics remain supportive, with the services sector continuing to set the trajectory for broader business activity metrics despite the minor pullback in factory orders and production.
