Why Global Growth Reached a 27-Month PMI High in August

The August PMI data point to a global expansion that was gaining breadth: services remained the principal engine, while manufacturing and equipment spending improved. The J.P. Morgan Global Composite PMI rose to 53.5, described as a 27-month high, with stronger new orders and employment alongside the acceleration. 3

That is a meaningful improvement, but it should be read carefully. A PMI is a timely survey of business conditions, not an official measure of output. The frequently cited estimate of roughly 3.0% annualized global GDP growth is an inference from the historical relationship between PMI readings and GDP, rather than a GDP release. 39

Services supplied the immediate lift

The global data indicate that services were central to the acceleration. That pattern was especially visible in the United States, where the flash composite PMI rose to 56.0 in August as services activity strengthened, even as manufacturing growth slowed. 433

A services-led improvement matters because services account for a large share of activity in many major economies. Stronger new business in areas such as finance, technology and other business services can lift the composite index quickly, while consumer-facing services add support when household demand is resilient. The global PMI report also identified stronger new orders and employment in August. 3

Equipment spending gave manufacturing a second engine

The improvement was not solely a services story. Global manufacturing conditions strengthened in August, with the manufacturing PMI moving from 49.7 in July to 50.9—back above the 50 threshold that separates expansion from contraction. 16

S&P Global had already reported a surge in equipment spending at the start of the third quarter, when PMI data were consistent with a 2.6% annualized global growth pace. 45 By August, reports linked the further acceleration in manufacturing to ongoing AI investment and equipment spending. 39

This is the clearest way to interpret the AI connection: data-centre and AI infrastructure investment creates demand for the physical inputs required to build and operate computing capacity, including technology equipment and broader capital goods. It can therefore support both manufacturing output and service-sector activity tied to technology and finance. The supplied evidence supports this investment channel, but it does not establish that AI alone caused the entire global PMI rise. 3945

Europe showed improvement, not a uniform boom

The euro area’s August flash composite PMI was 52.1, up slightly from 52.0 in July and a nine-month high. Manufacturing output was notably stronger at 53.4, while services activity was more modest at 51.7. 35

That split reinforces the broader global message: industrial activity improved, but the pace of expansion differed across sectors and countries. Europe’s AI-infrastructure push also remains uneven. Spain and Italy have been identified as comparatively strong data-centre growth markets, while France has strong digital infrastructure but lags in business digitalisation, according to European Commission reporting. 2117

Why the growth signal does not settle the full-year outlook

A high PMI reading improves the near-term case for global growth, but it does not eliminate downside risks. S&P Global’s August outlook put 2026 global real GDP growth at 2.4%, despite raising its forecast in July and August; that was still 0.5 percentage point below its February pre-conflict projection. 38

Business confidence is an important counterweight. In an earlier global August PMI release, S&P Global said expectations for the year ahead had fallen to one of their weakest levels since the pandemic, with concerns focused particularly on U.S. policy changes and tariffs. 13

The practical conclusion is that the August acceleration looks investment- and services-led rather than a broad, confidence-led global boom. Sustained gains would require the improvement in equipment demand, manufacturing and services to persist while trade and geopolitical uncertainty recede. A single strong PMI month is encouraging, but it is not enough to confirm a durable shift in the annual growth trajectory.

What the PMI can—and cannot—say about markets

The survey supports the case for firmer near-term activity. It does not, on its own, prove a lasting rise in inflation, bond yields or government-debt term premia, nor does it determine whether Treasuries will hedge the next downturn. Those outcomes depend on inflation dynamics, fiscal policy, energy prices, central-bank decisions and the nature of any future shock—evidence not established by the PMI release alone.

For investors and decision-makers, the useful signal is narrower: August showed that global demand was more resilient than a weak-growth narrative would suggest, with services and capital spending doing much of the work. The remaining question is whether that resilience can outlast policy uncertainty and the still-subdued confidence outlook. 31338
