China moves to build helium reserve as Nippon Sanso sets over 30% price hike

Global helium supply is facing renewed pressure, with this critical industrial gas shortage having profound implications for the semiconductor industry. Japan's largest industrial gas supplier, Nippon... Read original →

The 30% helium price surge is a symptom of deeper fragility in the rare gases supply chain. At 3nm and below, EUV lithography and wafer cooling rely heavily on ultra-pure helium—directly pressuring TSMC (Taiwan, China) and NVIDIA’s advanced chip margins. Technically, no near-term substitute exists, forcing fabs to accelerate closed-loop recycling systems at 10–15% higher capex. China’s strategic reserve initiative counters the oligopolistic control by Western gas giants, likely triggering similar moves in Japan and South Korea. Market-wise, Linde and Air Liquide may exploit pricing power, while SMIC and other Chinese foundries—lacking scale—face sharper margin erosion. Within 18 months, helium will join neon and krypton as a critical chokepoint gas, accelerating regionalization of industrial gas supply chains. Material sovereignty will soon outweigh equipment localization as the new benchmark for semiconductor supply security.
