The Purchasing Managers’ Index (PMI) is a key gauge of economic health. But between the Services PMI and the Manufacturing PMI, which one best reflects the true rhythm of today’s economy? Let’s dive deeper into their roles and significance.
If GDP provides the big picture of economic performance, the Purchasing Managers’ Index (PMI) serves as an early indicator of business activity changes—often before official growth data is released.
Published monthly, PMI surveys hundreds of purchasing managers across key sectors such as manufacturing and services.
A reading above 50 indicates expansion, while below 50 signals contraction.
Both indices are released by leading institutions like the Institute for Supply Management (ISM) and S&P Global, but they represent different dimensions of the economy.
Criteria |
Manufacturing PMI |
Services PMI |
| Coverage | Measures goods production (factories, industrial, exports) | Measures service activities (finance, logistics, tech, healthcare, travel, education...) |
| Economic Focus | Sensitive to global cycles and trade flows | Reflects domestic demand and consumer strength |
| Volatility | Affected by input costs, supply chains, and interest rates | Tied to spending patterns and business services |
| Current Relevance | Declining share in modern economies | Increasing importance as services dominate GDP |
Over the past two decades, the global economy has shifted dramatically from manufacturing to services.
In the U.S., the services sector now accounts for over 70% of GDP, while manufacturing contributes roughly 11%. A similar trend is seen in Europe and Japan.
As a result, the Services PMI has become a crucial gauge of consumer demand, employment, and domestic confidence — key drivers of economic growth.
For instance:
Despite its reduced weight, Manufacturing PMI remains a vital early signal of global trade and investment cycles.
Industries like energy, heavy manufacturing, logistics, and exports still rely heavily on production trends.
When Manufacturing PMI rebounds after a downturn, it often marks the turning point of:
For investors, this index is particularly useful during transitional phases — when economies shift from contraction to expansion.
PMI releases often trigger immediate reactions across global markets:
For example, the U.S. Services PMI for September 2025 unexpectedly rose to 52.4 (vs. 50.8 expected), pushing bond yields higher and delaying expectations for a Fed rate cut until early 2026.
The short answer: Both – but prioritize the Services PMI in modern economies.
When both indices rise above 50, it typically signals broad-based expansion and a favorable environment for risk assets.
Releases typically occur around 9:45 a.m. and 11:00 a.m. ET (equivalent to 21:45 and 23:00 Vietnam time), when forex and gold markets see heightened volatility.
In today’s financial landscape, both Manufacturing and Services PMI are indispensable for understanding economic dynamics.
While Manufacturing PMI captures investment and export momentum, Services PMI reveals consumer sentiment and domestic vitality.
Mastering these indicators helps investors:
1. What does a PMI reading of 50 mean?
→ Above 50 signals expansion; below 50 indicates contraction in economic activity.
2. Why is the Services PMI more important now?
→ Because services dominate GDP and directly drive consumer spending — the backbone of modern economies.
3. How does PMI affect the Federal Reserve and markets?
→ Strong PMI readings can delay rate cuts, while weak data may trigger policy easing expectations.
4. Which PMI source should I follow?
→ Both S&P Global and ISM are valuable, but ISM’s version tends to carry greater market influence in the U.S.
