BUSINESSES CONTINUE BUILDING BUFFER STOCKS IN ANTICIPATION OF FURTHER DISRUPTION AS SUPPLY SHORTAGES PERSIST : GEP GLOBAL SUPPLY CHAIN VOLATILITY INDEX
- Manufacturers’ reports of backlogs rising due to shortages of critical inputs were at their highest since late 2022, signaling that supply-chain bottlenecks are likely to persist into at least the third quarter.
- Businesses continued building buffer inventories, driving another month of strong demand for raw materials, commodities and intermediate goods.
- Demand stayed strong in North America and Asia, but European manufacturers retrenched in June 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: Supply chain pressures eased from May's peak but remained the highest in the world, driven by continued stockpiling and strong purchasing activity.
Europe: Factory purchasing weakened as manufacturers retrenched, although businesses continued building inventories.
U.K.: Supply chain pressures eased as manufacturers retrenched.
North America: Manufacturers sharply increased purchasing as shortages of critical inputs and order backlogs continued to rise.
The next release of the GEP Global Supply Chain Volatility Index will be published at 8 a.m. ET on Aug. 12, 2026.
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 compiled 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.
