Middle East War Sends Global Supply Chain Volatility to Three-Year High
Event summary
- GEP's Global Supply Chain Volatility Index surged from 0.09 in February to 0.57 in March 2026, the highest level since January 2023.
- Asia experienced the most significant supply chain pressures, with the index jumping to 1.16 from 0.40.
- Global transportation costs reached a four-year high due to surging oil prices, particularly impacting Asia.
- Material shortages hit a three-year high, with polymers, PVC, rubber, aluminum, and copper being the most affected.
- European manufacturers engaged in the most aggressive safety stockpiling amid anticipated price rises and supply chain disruption.
The big picture
The escalation in Middle East conflict has triggered a sharp increase in global supply chain volatility, with manufacturers responding by stockpiling and transportation costs surging. While the immediate impact has not yet slowed global economic growth, the bottlenecks in critical materials and regional disparities in pressure highlight the need for strategic supply chain adjustments. The situation underscores the vulnerability of global supply chains to geopolitical shocks, particularly in energy-dependent regions like Asia.
