The August ISM Services PMI printed 55.4%, above the 54.0 consensus, as sector activity surged while employment contracted for a second straight month.
- The August ISM Services PMI registered 55.4%, beating the 54.0 consensus and rising 1.3 percentage points from July's 54.1%
- Business Activity jumped to 61.7% and New Orders to 60.9%, two of the strongest sub-index readings of the current expansion
- The Services Employment sub-index contracted for a second consecutive month at 47.8%, a divergence from the surging order and activity data
Lead
The Institute for Supply Management Services PMI for August registered 55.4% on Wednesday, September 3, topping the 54.0 consensus forecast and extending the sector's unbroken expansion to 26 consecutive months. The release arrived as the morning's pivotal macro number after Tuesday's ADP private-payrolls count fell to just 38,000 - the softest monthly gain since January - raising the prospect of a deteriorating labor market ahead of the Federal Reserve's September 15-16 rate decision. Rather than validating the hard-landing fears, the ISM print delivered the opposite: the services sector, which accounts for more than 85% of U.S. employment, accelerated in August even as its internal hiring gauge remained in contraction territory.
What Does the 55.4% Reading Signal for Growth?
The August services gauge indicates the broader economy continues to expand at a meaningful pace. At 55.4%, the ISM's own historical correlation translates the result to approximately 2.3% annualized GDP growth. The Business Activity sub-index climbed 2.6 percentage points to 61.7%, while the New Orders sub-index surged 3.7 points to 60.9%, both readings among the most expansionary of the current cycle. The report's breadth undercuts any narrative that the ADP weakness signals an imminent service-sector contraction. Separately, the August ISM Manufacturing PMI eased to 54.6% from a 55.2% estimate, leaving the goods sector slightly softer but still in expansion territory.
Why Did the ADP Report Ignite Alarm Before the Open?
The ADP national employment report released Tuesday showed private-sector payrolls rose by just 38,000 in August, the smallest gain since January and below economists' forecasts near 48,000. The composition was highly concentrated: education and health services accounted for 45,000 new positions, leisure and hospitality added 16,000, and construction contributed 12,000, while manufacturing shed 17,000 jobs and professional and business services contracted by 16,000. Companies with 500 or more employees generated 34,000 of the net gains; businesses with fewer than 50 workers added just 3,000. The report triggered a brief bond-market rally on rate-hike repricing before the ISM upside surprise partially reversed the move.
The Employment Subindex's Quiet Contradiction
The ISM report's internal labor data reinforce rather than negate the ADP concern. The Services Employment sub-index registered 47.8% in August - a second consecutive month in contraction, with any reading below 50 signaling declining headcount across responding businesses. The sub-index has averaged 47.9% since March, reflecting persistent caution among service-sector employers even as their order books fill. Some respondents attributed rising backlogs to understaffing rather than excess demand, a pattern that may eventually force hiring - or constrain the activity growth that Business Activity and New Orders data currently suggest.
How Does This Reshape the September Interest Rates Decision?
Markets entered Wednesday with CME FedWatch pricing a 25-basis-point rate hike at the September 15-16 Federal Open Market Committee meeting at roughly 65-68%, a level that had nearly doubled after Federal Reserve Chair Kevin Warsh's hawkish Jackson Hole address. The ADP miss began trimming those odds; the ISM beat re-introduced uncertainty, with some futures markets settling the probability near 48-56%. Fed Governor Christopher Waller said he would be "inclined to support" holding interest rates steady if upcoming inflation data continue to show improvement. The ISM Prices Paid sub-component - a direct read on service-sector cost pressures - remains the key variable for bond traders through the week. A move in the prime rate, which tracks the fed funds rate in lockstep, would ripple immediately into variable-rate consumer and commercial debt.
Market Reaction
Equities snapped a three-day losing streak after the ISM beat. The S&P 500 (SPY) advanced 0.57%, the Dow Jones Industrial Average gained 0.80%, the Nasdaq (QQQ) climbed 0.64%, and the Russell 2000 rose 1.13%. The 10-year Treasury yield pulled back to approximately 4.75% from a recent peak near 4.81%, as traders partially unwound the aggressive rate-hike pricing embedded after Jackson Hole. Geopolitical risk - Iranian missile and drone strikes on Jordan, the United Arab Emirates, and Kuwait - remained an ambient pressure on sentiment but did not derail the risk rally.
Outlook
The August ISM Services PMI at 55.4% is the week's strongest macro datapoint and provides genuine support for the soft-landing thesis in the near term. Business Activity at 61.7% and New Orders at 60.9% point to durable demand through the fall. The contradiction embedded in a second successive employment contraction at 47.8% - alongside a labor market already strained by the ADP's 38,000 print - means the picture remains incomplete. Friday's nonfarm payrolls report is the final major input before the September 16 FOMC meeting, where interest rates could shift by 25 basis points depending on the headline jobs figure and revisions to prior months.
