SUPPLY CHAIN SPARE CAPACITY INCREASES TO HIGHEST LEVEL IN FIVE YEARS DUE TO TARIFFS: GEP GLOBAL SUPPLY CHAIN VOLATILITY INDEX

  • In March, global supply chains were underutilized to the greatest degree since May 2020, the height of the COVID-19 pandemic, indicating rapidly worsening conditions for global manufacturers.
  • Factories in the U.S., Mexico and Canada retrenched in March due to tariffs, with purchasing activity down the sharpest in Canada
  • UK supplier activity contracting at a rate that has only ever been surpassed in early 2020 and 2008-09, signaling considerable manufacturing weakness   more ..

Interpreting the data:

When the SCVI > 0, supply chain capacity is being stretched. The further above 0, the more stretched supply chains are.

When the SCVI < 0, supply chain capacity is being underutilized. The further below 0, the more underutilized supply chains are.

ASIA: Suppliers at Full Capacity as Export Growth in China, Taiwan, and India Surges

EUROPE: Industrial Slowdown Persists, but Early Signs of Recovery Emerge

U.K.: Worsens as Index Falls to Lowest Since Dec. ‘23

NORTH AMERICA: U.S., Canada and Mexico Report Sharp Declines

The next release of the GEP Global Supply Chain Volatility Index will be 8 a.m. ET, May. 13, 2025.

 

JUST A FEW MORE THINGS ABOUT YOU

About the GEP Supply Chain Volatility Index

The GEP Global Supply Chain Volatility Index is produced by S&P Global and GEP. The GEP Global Supply Chain Volatility Index is derived from S&P Global’s PMI™ surveys, sent to companies in over 40 countries, totalling around 27,000 companies. These countries account for 89% of global gross domestic product (GDP) (source: World Bank World Development Indicators).

The headline figure is the GEP Global Supply Chain Volatility Index. This a weighted sum of six sub-indices derived from PMI data, PMI Comments Trackers and PMI Commodity Price & Supply Indicators complied by S&P Global.

The GEP Global Supply Chain Volatility Index is calculated using a weighted sum of the z-scores of the six indices. Weights are determined by analysing the impact each component has on suppliers’ delivery times through regression analysis.

The six variables used are 1) JP Morgan Global Quantity of Purchases Index, 2) All Items Supply Shortages Indicator, 3) Transport Price Pressure Indicator and Manufacturing PMI Comments Tracker data for 4) stockpiling due to supply or price concerns, and backlogs rising due to 5) staff shortages and 6) item shortages.

A value above 0 indicates that supply chain capacity is being stretched and supply-chain volatility is increasing. The further above 0, the greater the extent to which capacity is being stretched.

A value below 0 indicates that supply chain capacity is being underutilized, reducing supply-chain volatility. The further below 0, the greater the extent to which capacity is being underutilized.

A Supply Chain Volatility Index is also published at a regional level for Europe, Asia, North America and the UK. The regional indices measure the performance of supply-chains connected to those parts of the world.
