Middle East Tensions Threaten Global Semiconductor Supply Chains, South Korean Officials Warn
Senior South Korean government officials have issued a new warning that any escalation of conflict between the US-Israel bloc and Iran that disrupts critical industrial material exports out of the Middle East could send major shockwaves through the global semiconductor supply chain.
South Korea’s semiconductor industry, headed by global manufacturing powerhouses Samsung Electronics and SK Hynix, accounts for roughly two-thirds of the entire world’s memory chip output. Should supplies of key chipmaking raw materials from the Middle East be interrupted, semiconductor manufacturing could slow sharply unless alternative suppliers can be secured rapidly.
The Critical Helium Supply Risk
One core material facing immediate disruption risk is helium, an irreplaceable input for advanced chip manufacturing. Fabs rely on helium to dissipate heat, detect leaks in fabrication equipment, and maintain consistent stable operating temperatures for production tools. For most of these essential use cases, no viable commercial substitute exists today.
Roughly 38% of the world’s total helium supply is produced in Qatar, where large-scale helium extraction is integrated directly into the country’s massive natural gas industry. This heavy concentration of production in a single region means any operational disruption there can quickly ripple through every link of the global semiconductor supply chain.
On March 4, Qatar’s state-owned national energy firm QatarEnergy declared force majeure on all exports after halting natural gas production and downstream operations in response to ongoing regional attacks. Downstream facilities process raw natural gas into a range of finished products including urea, polymers, methanol, and aluminum, in addition to extracting helium as a key byproduct.
South Korea’s Ministry of Industry notes the country also depends on Middle Eastern suppliers for 14 other critical chipmaking inputs, ranging from bromine to specialized chip-inspection machinery. While a small share of these materials can be sourced domestically or from other global markets, switching suppliers in the semiconductor sector is notoriously difficult. Chipmakers must rigorously test and validate all new material sources to meet the industry’s extremely strict purity standards, a process that can take months to complete.
Chipmakers Say Near-Term Risk Remains Manageable
For the moment, major industry players report the current situation is still under control. Per reporting from Reuters, SK Hynix confirmed it has already diversified its supply base and maintains sufficient helium inventory to cover ongoing operations, adding there is “almost no chance” its production will be disrupted in the near term.
TSMC, the world’s largest contract chipmaker, echoed that assessment, noting it does not currently anticipate any significant operational impact from regional tensions. Another major global contract manufacturer GlobalFoundries added that it is in constant direct communication with its regional suppliers and has already implemented contingency mitigation plans to address any potential disruptions.
Maritime Chokepoints Add Layers of Vulnerability
Even if Qatar restarts full production quickly, the semiconductor industry remains exposed to disruptions in regional shipping routes. The vast majority of energy and petrochemical exports from the Persian Gulf pass through the Strait of Hormuz, one of the world’s most critical maritime chokepoints.
An extended interruption to shipping through this corridor would slow the movement of the industrial gases and petrochemical inputs that chipmakers depend on for daily production. Already, disruptions to regional oil and gas exports have pushed global energy prices higher; as of this writing, Brent crude, the European benchmark for oil pricing, trades at roughly $80 per barrel.
Energy costs make up a large share of total semiconductor production expenses. Chip fabrication facilities operate massive, climate-controlled clean rooms that require 24/7 access to low-cost electricity and cooling, leaving manufacturers extremely sensitive to even small shifts in global energy prices. South Korean industry representatives warn that a prolonged regional conflict would push energy prices even higher, translating to increased production costs for chipmakers and ultimately higher consumer prices for semiconductors across all sectors.
These new supply risks come at a time when global semiconductor supply chains are already stretched thin by exploding demand for AI-related computing. Surging chip demand from AI data center operators has already tightened supplies across multiple consumer and industrial sectors, including smartphones, laptops, and automobiles.
Long-Term Instability Creates Sustained Pressure
Right now, the full immediate impact of regional tensions on global chip production remains unclear. Most large chipmakers maintain diversified supplier rosters and stockpile specialty gases and chemicals to buffer against short-term disruptions, as a standard industry practice.
But if regional instability continues, pressure on global supply chains will almost certainly grow. A drawn-out conflict that damages energy infrastructure, export facilities, or regular shipping through the Persian Gulf could slowly tighten the global supply of the specialty materials required for chip manufacturing.
This sustained supply squeeze could even delay plans by major global technology firms to expand artificial intelligence infrastructure across the Middle East. Firms including Amazon, Microsoft, and Nvidia have already invested heavily in positioning the United Arab Emirates as a key regional hub for AI computing capacity.
