The War on Iran Puts Global Chip Supplies and AI Expansion at Risk

South Korea’s Chip Giants on Edge as Iran Conflict Threatens Global Semiconductor Supply Chain

The escalating US-Israel conflict with Iran has sent shockwaves through the global technology sector, with South Korean officials warning that the semiconductor supply chain could face severe disruptions if the Middle East conflict interferes with the flow of critical industrial materials.

South Korea’s semiconductor industry, dominated by powerhouses Samsung Electronics and SK Hynix, produces approximately two-thirds of the world’s memory chips. These companies have built their success on sophisticated manufacturing processes that rely on specialized materials sourced from across the globe, making them particularly vulnerable to regional instability.

The Helium Crisis: A Critical Bottleneck

At the heart of the concern lies helium, an irreplaceable element in chip manufacturing. This inert gas plays crucial roles in heat management, leak detection, and maintaining stable temperatures during the fabrication process. For many of these applications, semiconductor manufacturers have no viable alternatives.

The global helium market faces a significant concentration risk, with Qatar producing about 38 percent of the world’s supply. The Gulf nation’s helium extraction facilities are deeply integrated with its natural gas industry, creating a single point of failure that has now been exposed by the conflict.

National oil company QatarEnergy declared force majeure on March 4, halting its gas production and downstream operations following attacks in the region. Downstream facilities are essential for converting raw natural gas into products like urea, polymers, methanol, and aluminum—all of which have semiconductor applications or support roles.

Beyond Helium: A Web of Dependencies

South Korea’s Industry Ministry has identified 14 additional materials critical to chip manufacturing that come from the Middle East, including bromine and specialized chip-inspection equipment. While some of these materials can be sourced domestically or from alternative markets, the semiconductor industry’s stringent purity requirements make rapid supplier transitions extremely challenging.

Companies must undergo extensive testing and validation when introducing new material sources to ensure they meet the microscopic tolerances required for modern chip production. This process can take months or even years, creating a significant barrier to quick supply chain adjustments.

Industry Response: Preparedness vs. Uncertainty

Despite the mounting concerns, major chip manufacturers are attempting to project confidence. SK Hynix has stated that it has diversified its supply chains and maintains substantial helium inventories, claiming there is “almost no chance” its operations would be affected in the near term.

Taiwan Semiconductor Manufacturing Company (TSMC), the world’s largest contract chipmaker, has similarly stated it does not anticipate a significant impact. GlobalFoundries has reported that it is in direct contact with suppliers and has mitigation plans in place.

However, industry analysts note that these reassurances may be more about maintaining market stability than reflecting the true complexity of the situation. The semiconductor industry’s just-in-time manufacturing model leaves little room for error when critical materials are disrupted.

Maritime Choke Points: The Strait of Hormuz Risk

Even if Qatar’s gas production resumes, the semiconductor industry faces another layer of vulnerability through regional shipping routes. The Persian Gulf’s energy and petrochemical exports must pass through the Strait of Hormuz, a maritime choke point that handles approximately 20 percent of the world’s oil supply.

A prolonged disruption of shipping through this corridor could severely impact the movement of industrial gases and petrochemicals that chipmakers depend on. The conflict has already triggered price increases in global energy markets, with Brent crude reaching $80 per barrel.

Energy Costs: The Hidden Multiplier

Energy costs represent a significant portion of semiconductor production expenses. Fabrication plants require massive amounts of electricity to power clean rooms that must maintain precise temperature, humidity, and particle control. These facilities run 24/7, making chipmakers extremely sensitive to energy price fluctuations.

Industry representatives in South Korea have warned that a prolonged conflict could drive energy prices even higher, potentially leading to increased semiconductor production costs and ultimately higher chip prices for consumers. This creates a cascading effect that could impact everything from smartphones to artificial intelligence infrastructure.

AI Expansion Plans in Jeopardy

The timing of this supply chain vulnerability is particularly concerning given the current boom in artificial intelligence computing. Chip demand from AI data center operators has already tightened supply across multiple electronics sectors, including smartphones, laptops, and automobiles.

Major technology companies have been positioning the United Arab Emirates as a hub for AI computing capacity, with firms like Amazon, Microsoft, and Nvidia investing heavily in Middle East infrastructure. A prolonged conflict could derail these expansion plans, potentially slowing the global rollout of AI capabilities.

The Long Game: Structural Vulnerabilities

While the immediate impact on chip production remains unclear, the conflict has exposed fundamental vulnerabilities in the global semiconductor supply chain. Major chipmakers typically maintain diverse supplier networks and stockpile specialty materials to weather short-term disruptions, but these buffers have limits.

If regional instability continues, pressure on supply chains will likely intensify. A drawn-out conflict affecting energy infrastructure, export facilities, or shipping routes could gradually squeeze the global supply of materials essential for chipmaking. This could create a slow-moving crisis that unfolds over months rather than days.

A Wake-Up Call for Diversification

The current situation serves as a stark reminder of the semiconductor industry’s interconnected nature and its vulnerability to geopolitical events. It may accelerate efforts to diversify supply chains and develop alternative sources for critical materials, though such initiatives require substantial investment and time to implement.

As the conflict continues to evolve, the global technology sector watches closely, knowing that the stability of the Middle East has become inseparable from the future of computing, artificial intelligence, and the digital economy as a whole.
