Qatar produces approximately 30% of the world's helium supply. The Hormuz Strait closure has blocked exports from the North Field — the world's largest natural gas reservoir, which sits offshore between Qatar and Iran [1].

Helium is not a substitute input in semiconductor manufacturing — it is a physical requirement. Liquid helium cools the superconducting magnets in MRI machines. It is essential for wafer processing, lithography, and the cooling systems that keep chip fabrication equipment within operating temperature ranges. There is no alternative coolant for several of these applications [2].

The disruption threatens fabs that were already operating under allocation constraints. TSMC, Intel, and Samsung all use helium in production processes. A sustained shortage forces production slowdowns — not shutdowns, but reduced throughput that delays chip deliveries by weeks to months [1].

The timing is particularly acute. The global semiconductor industry was recovering from the 2024-2025 supply chain disruptions caused by the Taiwan Strait tensions. fabs had rebuilt inventory buffers. The helium shortage strikes at a supply chain node that cannot be stockpiled — liquid helium evaporates if not continuously refrigerated, so there is no strategic reserve [3].

Medical device manufacturers face parallel exposure. MRI machines require liquid helium to function. GE Healthcare and Siemens Healthineers both depend on Qatari helium supply. Hospitals in Europe and Asia reported Monday that scheduled MRI procedures were being delayed due to supply uncertainty [2].
