The Economics of Global Manufacturing PMIs: Interpreting Supply Chain and Inflation Trends (2025)
Global Manufacturing Navigates an Uneven Recovery in Early 2025, Supply Chains and Inflation Remain Key Concerns

The global manufacturing sector presents a mixed picture in early 2025, with Purchasing Managers' Index (PMI) data revealing an uneven recovery and persistent challenges related to supply chains and inflation. While some regions show signs of expansion, overall conditions remain fragile, influenced by geopolitical tensions, trade policies, and shifting demand patterns.

Understanding the Global Manufacturing PMI

The Global Manufacturing PMI is a key indicator of the sector's health. It's a composite index based on five sub-indices: new orders (30%), output (25%), employment (20%), suppliers' delivery times (15%), and stocks of purchases (10%). A reading above 50 indicates expansion, while below 50 signals contraction. It's important to note that for the PMI calculation, the Suppliers' Delivery Times Index is inverted. This means that longer delivery times, typically a negative sign for supply chains, contribute positively to the headline PMI figure.

Recent Trends and Regional Variations

As of April 2025, the J.P. Morgan Global Manufacturing PMI, compiled by S&P Global, dipped to 49.8 from 50.3 in March, indicating a marginal worsening of business conditions for the first time in the year. This followed a period at the end of 2024 where the global manufacturing sector fell back into contraction, with the PMI at 49.6 in December, down from 50.0 in November.

Regional divergences are significant. In early 2025:

  • United States: The ISM Manufacturing PMI for the U.S. slipped to 48.7 in April 2025, signaling a second consecutive month of contraction. This was attributed to shrinking output and rising prices, with new export orders falling steeply amid ongoing tariff-related disruptions. Earlier in February, the S&P Global US Manufacturing PMI had reached a 32-month high at 52.7, partly driven by advanced purchases ahead of anticipated price hikes and supply issues related to tariffs.
  • Eurozone: Manufacturing PMI showed the Eurozone factory output rising for the first time in two years in March 2025, driven by improving domestic demand. However, the overall manufacturing PMI for the Eurozone remained in contraction in February (46.6), though it hit a two-year high, indicating a mild recovery in demand but continued weakness in employment.
  • Asia: Developing Asia has shown resilience, with PMI data indicating continued expansion in most economies in early 2025, driven by higher export orders. China's manufacturing activity showed sustained growth among smaller private businesses and exporters. India also reported strong expansion. However, Japan's manufacturing PMI remained in contraction in February due to weak demand and rising labor costs. South Korea's PMI also dipped due to weak domestic demand, though export orders grew.
  • Canada: The S&P Global Canada Manufacturing PMI indicated growth for the fourth successive month in December 2024, with firms noting better sales to U.S. clients due to inventory accumulation ahead of expected U.S. tariffs on Canadian goods in 2025. However, by March 2025, Canadian factory output fell at the sharpest rate in 15 months as export orders slumped.
  • United Kingdom: UK manufacturers reported steep job and export losses in early 2025.

Supply Chain Dynamics

Supply chain issues continue to influence global manufacturing. At the end of 2024 and into early 2025, suppliers' delivery times lengthened globally, in some cases to the greatest extent since October 2022. This was often linked to staff shortages at suppliers and freight delays. Tariff concerns and trade protectionism are also disrupting supply chains, causing shipping delays, complex duties, and frequent changes in cost structures. Some businesses engaged in "front-loading" activity, building inventories to beat potential tariffs and price hikes, which temporarily boosted production and new orders in some regions. For instance, some Canadian firms reported increased sales to US clients accumulating inventory ahead of anticipated tariffs in 2025.

Inflationary Pressures Persist

Inflation remains a significant concern. Average prices charged by factories worldwide rose in April 2025 at the fastest rate since March 2023. Companies commonly hiked prices in response to tariffs and rising input costs.

  • In the US, manufacturers reported grappling with rising costs and margin pressure. February saw input cost inflation at its highest since November 2022, and output charges inflation accelerated to a two-year high.
  • In the Eurozone, while input prices continued to rise in February, weak demand led some firms to absorb these costs, resulting in slightly lower output prices compared to the previous month.
  • Canada saw a sharp acceleration in the rate of input cost inflation at the end of 2024, with firms increasing output prices in response.
  • Irish manufacturers reported that while input costs rose, competitive pressures constrained price rises for outputs in March 2025.
  • South Korea experienced intensified input inflation due to rising raw material costs in February, prompting businesses to raise output prices at the sharpest rate in 15 months.

Outlook and Key Factors for 2025

Looking ahead, the global manufacturing landscape in 2025 will likely be shaped by several factors:

  • Trade Policies and Tariffs: The imposition or threat of tariffs continues to create uncertainty, impacting export orders, supply chain strategies, and input costs. The possibility of US tariffs being imposed in 2025 was a recurring theme affecting business conditions at the end of 2024 and into the new year.
  • Geopolitical Stability: Ongoing geopolitical tensions and conflicts add another layer of risk and uncertainty, potentially impacting energy prices, supply routes, and overall business confidence.
  • Demand Dynamics: Fluctuations in global and domestic demand will be crucial. While some regions are seeing improved demand, others continue to struggle with weakness. Customer demand has become more volatile, with some clients delaying orders or pushing tariff costs back onto manufacturers.
  • Inflation Trends: The trajectory of input and output price inflation will significantly impact manufacturers' profitability and pricing strategies. Rising cost pressures, notably in the US, pose a threat of higher inflation.
  • Business Confidence: Business sentiment has been affected by the uncertainty. The PMI's index of future output expectations plunged in April 2025 to its lowest since October 2022, nearing lows seen in 2019 when trade protectionism escalated.

In conclusion, while pockets of growth exist, the global manufacturing sector in early 2025 is treading a path of cautious and uneven recovery. Navigating supply chain complexities and persistent inflationary pressures, exacerbated by trade uncertainties and geopolitical factors, will be the primary challenge for manufacturers worldwide throughout the year. Monitoring PMI sub-indices like new orders, supplier delivery times, and input/output prices will be crucial for understanding the evolving economic landscape.
