China has blocked exports of helium, a critical gas used in semiconductor manufacturing and medical imaging, as the ongoing closure of the Strait of Hormuz intensifies a global supply crunch. The move, reported by The Associated Press on July 10, 2026, adds to mounting pressures on industries reliant on the rare element.
Strait of Hormuz Closure Worsens Helium Crisis
The Strait of Hormuz, a narrow waterway between Iran and Oman, has been effectively closed due to heightened military tensions linked to the Iran war. This chokepoint normally handles about 30% of the world's helium shipments, primarily from Qatar and other Middle Eastern producers. With shipping halted, global helium inventories have plummeted, driving prices to record highs.
China, a major helium consumer and re-exporter, has now imposed its own export restrictions to conserve domestic supplies. The Chinese government did not specify a timeline for the ban, but industry analysts warn it could last months.
Impact on Chipmaking and Healthcare
Helium is essential for cooling superconducting magnets in MRI machines and for creating inert atmospheres in semiconductor fabrication. The shortage threatens to disrupt production at chip fabs worldwide, including those in Taiwan, South Korea, and the United States. "Without helium, advanced chip manufacturing grinds to a halt," said Dr. Emily Zhang, a supply chain expert at the Semiconductor Industry Association. "This could delay everything from smartphones to medical devices."
Hospitals are also feeling the strain. MRI scans rely on liquid helium to keep magnets at near-absolute zero temperatures. Some facilities have already postponed non-urgent scans, and the American College of Radiology has issued a warning about potential diagnostic delays.
Global Helium Reserves Dwindle
According to the U.S. Geological Survey, global helium reserves have fallen by 15% since the Strait of Hormuz closure began in June 2026. The United States, which operates the Federal Helium Reserve in Texas, has increased drawdowns but cannot fully compensate for lost Middle Eastern supplies. Russia's new Amur helium plant, expected to come online later this year, has faced construction delays due to sanctions.
"We are in uncharted territory," noted Mark Thompson, a commodities analyst at IHS Markit. "The combination of a geopolitical blockade and export restrictions is unprecedented in the helium market."
Ripple Effects Across Industries
Beyond electronics and healthcare, helium is used in arc welding, leak detection, and as a pressurizing agent for rocket fuel. NASA has expressed concern about potential impacts on space missions. The entertainment industry, which uses helium for balloons, is also facing shortages, with party supply stores reporting empty tanks.
In Ottawa, CTV's Austin Lee reported that Canadian hospitals are rationing helium supplies. "We are prioritizing emergency scans and canceling elective procedures," said Dr. Sarah Mitchell, chief radiologist at Ottawa General Hospital. "It's a crisis we didn't anticipate."
The Chinese export ban is expected to deepen the shortage, with spot prices for helium rising 40% in the past week alone. Industry groups are urging governments to release strategic reserves and invest in recycling technologies.
Outlook and Mitigation Efforts
The International Helium Industry Association has called for diplomatic efforts to reopen the Strait of Hormuz. Meanwhile, companies are exploring alternatives, such as helium recovery systems and substitute cooling technologies. However, these solutions are years away from widespread adoption.
For now, the global economy faces a stark reality: a vital resource is being squeezed from two directions simultaneously, with no quick fix in sight.
