US PMI Surveys Signal Growth Rebound In Q3, Strongest Among Global Peers
August US services PMI readings strengthened, with S&P Global at 56.5 and ISM at 55.4, pointing to a Q3 growth rebound that outpaces major global peers. The setup supports a firmer US-growth and rates narrative, but the divergence between survey strength and languishing hard data leaves the signal vulnerable to confirmation from upcoming activity releases.

The read · Sep 3
The stronger August services PMIs reinforce the US-growth side of the macro trade, but the hard-data gap keeps the signal from carrying a clean directional read.
Wrong if
The setup fails if upcoming hard-data releases do not validate the August services and composite PMI improvement, or if services momentum reverses in September.

The story1 min read
The August US services surveys delivered a stronger read than expected after mixed manufacturing data earlier in the week. S&P Global’s Services PMI rose from 54.6 to 56.5, although it came in below the preliminary 56.8 reading; the result was still the highest since December 2024. The Institute for Supply Management’s Services PMI increased from 54.1 to 55.4, beating the 54.1 expectation and reaching its highest level since February 2026.
Together, the surveys point to a broadening rebound in US private-sector activity during the third quarter. The S&P Global US Composite PMI reached 56.0 in August, up from the prior reading cited in the report. That follows weaker or mixed manufacturing survey data, making services the main source of the improvement in the overall activity signal.
The direct transmission runs through the US growth outlook and the rates market rather than a single company. Stronger services activity can support expectations for continued demand across consumer- and business-facing industries, while a firmer composite reading can reduce pressure for near-term policy easing if it is reflected in subsequent economic data. The report also frames the US as showing the strongest growth momentum among its global peers.
The evidence is not cleanly one-sided. S&P Global’s final services figure was below its preliminary 56.8 reading, and the source notes that hard data remains weak despite the survey improvement. Manufacturing did not provide a comparable confirmation earlier in the week, leaving open the possibility that the services strength reflects sentiment or survey volatility rather than a durable acceleration in output.
The next test is whether official activity data validate the August survey signal. Market participants will need to compare forthcoming hard-data releases with the 56.0 composite PMI and watch whether services momentum persists into September. The key unresolved issue is the gap between survey-based optimism and the weaker hard-data backdrop, alongside whether the services improvement broadens into manufacturing and other parts of the economy.
The read, in fullWhy it matters
The macro implication is a stronger US-growth signal, with the composite PMI at 56.0 and services readings at their highest points since December 2024 and February 2026. That support is offset by languishing hard data and weaker manufacturing evidence, so the survey rebound is not sufficient to establish a durable directional trade without confirmation.

▲ The case it holds
The S&P Global Services PMI rose to 56.5 and the ISM Services PMI to 55.4, giving the US a stronger Q3 activity signal than its global peers.
▼ The case it breaks
The opposing case is material: hard data remains weak, manufacturing surveys were mixed, and the final S&P Global services reading fell below the preliminary 56.8.
