Beyond oil, the conflict disrupts supply chains for materials like sulfur and helium, which are essential for producing copper, cobalt, and components used in semiconductor manufacturing. This creates a significant, non-obvious risk to the global tech industry.

Despite geopolitical tensions, Taiwan's world-leading semiconductor fabs are completely dependent on specialty gases imported from mainland China. An export restriction on a single chemical, like NF3, could shut down the entire Taiwanese chip industry, an often-overlooked vulnerability.

While the CHIPS Act successfully incentivizes fab construction, it fails to address the underlying chemical supply chain. Unlike China's holistic 'Big Fund,' this oversight means new US-based fabs will be totally reliant on imported specialty gases, undermining the goal of supply chain security.

The extreme energy intensity of advanced chipmaking creates a critical vulnerability. In Taiwan, the world's leading chip producer, a single major manufacturer uses up to 10% of the country's total power. This high-stakes dependency is amplified by Taiwan's limited LNG storage of only about one and a half weeks.

30% of the world's helium, essential for semiconductor manufacturing, passes through the Strait of Hormuz. A shutdown could halt a significant portion of global semiconductor production, impacting all electronics, a non-obvious consequence of the conflict.

Over 90% of the world's sulfur is a byproduct of oil refining. This sulfur is crucial for producing sulfuric acid, a key chemical in semiconductor manufacturing. Therefore, disruptions to oil shipping or refining create a hidden material supply chain risk for the tech industry, beyond just energy costs for power.

While oil is the obvious commodity affected by a Hormuz closure, a more fragile chokepoint for the high-tech economy is helium. It is essential for the ultra-cold temperatures needed in advanced chipmaking. With very little supply elasticity, a disruption here could halt the production of chips powering the AI revolution.

Leading-edge semiconductor manufacturing requires ultra-pure "six nines" helium. This necessitates a completely separate fleet of specialized liquid containers that can never be contaminated with lower-grade helium. This fractures the already constrained logistics network, creating a fragile "supply chain within a supply chain" for the most critical end-users.

The primary vulnerability in the global helium market is not production, but the logistics of its ~3,000 highly specialized liquid ISO containers. Because liquid helium is perishable and vents after ~45 days, any disruption that traps these containers creates a cascading global shortage, as the limited fleet cannot be redeployed quickly.
