The Purchasing Managers’ Index (PMI) serves as a valuable gauge of prevailing economic trends within the manufacturing and service sectors. This index consists of a diffusion scale, summarizing whether market conditions are expanding, remaining stable, or contracting, as assessed by purchasing managers. The primary aim of the PMI is to furnish real-time and prospective insights into business conditions for the benefit of company decision-makers, analysts, and investors.
Formula and Calculation of the Purchasing Managers’ Index (PMI):
The PMI is calculated using the following formula:
PMI = (P1 * 1) + (P2 * 0.5) + (P3 * 0)
Where:
- P1 represents the percentage of responses reporting an improvement.
- P2 denotes the percentage of responses indicating no change.
- P3 stands for the percentage of responses reporting a deterioration.
It’s noteworthy that various organizations, such as IHS Markit Group, also release PMI figures for countries outside the United States.
How the Purchasing Managers’ Index Works:
The PMI is an indispensable economic tool, recognized as one of the most reliable leading indicators of the U.S. economy. This index covers both the manufacturing and service sectors and is supplemented by a hospital PMI released on a monthly basis. It casts light on the prevailing business environment and provides valuable insights into the trajectory of the economy.
The PMI is survey-based and is compiled and published monthly by the Institute for Supply Management (ISM). The survey is distributed to senior executives at more than 400 companies across 19 primary industries, weighted according to their contributions to the U.S. gross domestic product (GDP).
These surveys encompass questions regarding business conditions and their changes, be it improvements, deteriorations, or stagnation. The PMI draws from five major survey areas, each carrying equal weight:
- New orders
- Inventory levels
- Production
- Supplier deliveries
- Employment
The headline PMI is represented as a numeric value ranging from 0 to 100. A PMI above 50 signifies an expansion compared to the preceding month, while a PMI reading under 50 signals a contraction, with a reading of 50 indicating no change. The farther the reading is from 50, the greater the level of change.
Using the PMI:
The PMI and the data derived from ISM’s monthly surveys play a pivotal role in decision-making across various sectors, including management, suppliers, and investors.
Corporate Managers:
Management leverages monthly PMI results to make critical decisions regarding their businesses. For example, an automobile manufacturer bases production decisions on anticipated new orders from customers in the coming months. These new orders drive the manufacturer’s purchasing decisions for components and raw materials like steel and plastic. Inventory levels also influence the necessary production to fulfill orders and maintain stock.
Suppliers:
Suppliers also rely on the PMI to estimate future demand for their products. Understanding their customers’ inventory levels is crucial, as this directly impacts the volume of production their clients must undertake. The PMI data related to supply and demand dynamics can influence pricing strategies, leading to adjustments in prices based on order growth or decline.
Investors:
Investors find value in the PMI as a leading indicator of economic conditions. The PMI’s trend often precedes changes in major economic metrics like GDP, industrial production, and employment. By closely monitoring the PMI and its fluctuations, investors can gain valuable insights into emerging economic trends.
What Are the Results of the Current Purchasing Managers’ Index?
As of May 2023, the Manufacturing PMI registered at 46.9%, representing a decline from the 47.1% reported in April 2023. The monthly report revealed a contraction in new orders and backlogs, while production and employment displayed growth compared to the previous month.
The Services PMI, on the other hand, indicated sustained economic growth, with a reading of 50.3% in May 2023. The ISM noted that this marked the fifth consecutive month of growth in this sector.
What Does the Global PMI Entail?
The Global PMI serves as an economic indicator derived from surveys sent to manufacturing and service companies in over 40 countries. Approximately 28,000 global companies participate in this survey, collectively representing 89% of global GDP.
What Is the Significance of a Elevated PMI Reading?
The PMI reading falls within a scale of 0 to 100. A reading above 50 signifies an economic expansion. The closer the reading is to 100, the more pronounced the positive economic growth. Conversely, a reading below 50 indicates an economic contraction, with lower values approaching 0 indicating a more significant degree of contraction. A reading of 50 indicates no change in the economic environment.
