Middle East Conflict Triggers Surge in Global Supply Chain Pressures, Says GEP Index

Global Supply Chain Pressures Escalate Amid Middle Eastern Tensions

The ongoing conflict in the Middle East has sent shockwaves through global supply chains, with the GEP Global Supply Chain Volatility Index rising to a three-year high as of March 2026. This index serves as a critical gauge, reflecting various metrics such as demand conditions, transportation costs, inventories, and shortages within the global supply network.

According to the latest findings, the index jumped from 0.09 in February to 0.57 in March, marking the highest volatility level since January 2023. This surge indicates that economic disruptions caused by the war have led to significant pressure on supply chains worldwide.

Key Findings from March 2026

1. Increased Stockpiling: Manufacturers globally are increasing their safety stockpiles in response to transportation disruptions and escalating costs. Reports indicate that stockpiling activity has reached levels not seen in three years. All major regions are witnessing enhanced inventory accumulation, particularly Europe, which is leading in this practice.

2. Labor Shortages and Bottlenecks: Despite a decrease in manufacturing demand, inventory shortages have skyrocketed, reaching their highest point since April 2023. The availability of essential materials like polymers, PVC, and crucial metals has significantly diminished. Moreover, reports of labor insufficiency have risen to a three-month high, intensifying backlogs across various industries.

3. Rising Transportation Costs: The conflict has pushed global oil prices to new heights, resulting in transportation costs surging to the highest levels recorded in nearly four years. Particularly in Asia, which is heavily dependent on Middle Eastern oil, these rising costs are felt acutely. Countries like Taiwan, Vietnam, South Korea, and Japan are experiencing substantial producer price inflation.

4. Region-Specific Impacts: The index for Asia has reached 1.16, the highest since August 2022, indicating severe supply chain pressures. In North America, the index moved from -0.26 to 0.42, reflecting the tightest supply chain circumstances since December 2022. Conversely, Europe’s index increased to 0.64, demonstrating heightened volatility as well.

Analyzing Global Demand

After peaking in February, the global demand for inputs, which measures the purchasing of raw materials and intermediate goods, weakened in March. This decline was primarily attributed to increased caution among manufacturers in Asia, where purchasing volumes have lessened. In North America and Europe, however, there was a slight uptick in purchasing activities due to expected price hikes and further disruptions in supply chains.

The Outlook Ahead

The war in the Middle East is reshaping the landscape for manufacturers and suppliers globally. While the current data indicates rising costs and shortages, experts suggest that these trends have not yet led to a broad economic downturn. Mukund Acharya, vice president of consulting at GEP, emphasizes the importance of strategic sourcing during times of uncertainty: companies must be decisive in securing supplies without engaging in excessive stockpiling, which could result in locked-in higher costs.

As the situation evolves, further disruptions to the supply networks are anticipated as geopolitical factors intensify. The GEP Global Supply Chain Volatility Index, a figure derived from analyzing a vast array of company surveys, will remain essential for understanding these dynamics moving forward. The next index release is scheduled for May 12, 2026, and all signs suggest that global supply chain management will need to navigate through choppy waters for the foreseeable future.
