TARIFF FEARS DRIVE U.S. STOCKPILING IN AUGUST, WHILE MANUFACTURING WEAKENS IN EUROPE AND ASIA: GEP SUPPLY CHAIN VOLATILITY INDEX
Rhea-AI Summary
The GEP Global Supply Chain Volatility Index declined to -0.39 in August from -0.35 in July, indicating increasing spare capacity in global supply chains. The report reveals significant regional variations:
North America showed strong activity with near-full capacity utilization, driven by companies stockpiling materials to hedge against tariff-related risks. Meanwhile, Asia's index hit a three-month low, with notable weaknesses in Japan and Taiwan, while Europe continued to decline, particularly in Germany's basic materials sector and UK manufacturing.
The UK experienced a sharp downturn, while China showed flat purchasing volumes. In contrast, South Korea, Indonesia, and particularly India demonstrated increased factory procurement activity. According to GEP's global head of supply chain strategy, companies must adapt to tariff uncertainty as a structural reality by focusing on resilience, supplier diversification, and enhanced demand sensing capabilities.
Positive
- North American supply chains operating at near-full capacity
- Increased factory procurement activity in South Korea, Indonesia, and India
- Companies actively adapting to tariff challenges through strategic stockpiling
Negative
- Global Supply Chain Volatility Index declined to -0.39, indicating increasing spare capacity
- Asia's index fell to three-month low with weakness in Japan and Taiwan
- European manufacturing deteriorated, particularly in Germany and UK
- China's purchasing activity remained flat in consumer non-cyclicals sector

AI-generated analysis. How Rhea-AI works. Not financial advice.
North America's supply chains get busier, with sharp stockpiling of components to guard against tariff-driven shortages and price inflationAsia's manufacturers cut purchases, led byJapan andTaiwan , and to a lesser extentChina Europe weakens further, dragged down byGermany and a sharp downturn in theUK
The global figure concealed stark regional contrasts.
By contrast,
"So far tariffs have neither spurred growth nor triggered collapse," said Michael DuVall, GEP's global head of supply chain strategy. "Tariff uncertainty is no longer a temporary, it's a structural reality in the supply chain. Companies need to manage it by reinvesting in resilience, diversifying suppliers, and building critical capabilities like demand sensing to make faster, smarter decisions."
Interpreting the data:
Index > 0, supply chain capacity is being stretched. The further above 0, the more stretched supply chains are.
Index < 0, supply chain capacity is being underutilized. The further below 0, the more underutilized supply chains are.
REGIONAL HIGHTLIGHTS
ASIA : Index fell to a three-month low to indicate rising spare capacity acrossAsia's supply chains as purchasing volumes inChina was flat. In contrast,South Korea ,Indonesia and particularlyIndia saw greater factory procurement activity.NORTH AMERICA : Supply chains were practically running at full capacity as recent orders were delivered and companies added to stock.EUROPE : Index falls again as factories purchased fewer intermediate goods and destocked. The data continue to highlight the fragile nature ofEurope's industrial recovery.U.K. : Index falls sharply to -asU.K. manufacturers cutback on procurement and inventories.
Interpreting the data:
Index > 0, supply chain capacity is being stretched. The further above 0, the more stretched supply chains are.

The headline figure is 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.
- 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.
