Middle East war triggers helium crunch, sends China gas prices up 10-fold

The helium crunch triggered by Middle East conflict is escalating from a niche material shortage into a systemic semiconductor bottleneck. Helium’s irreplaceable roles—in wafer cooling, lithography chamber purging, and final test—mean its tenfold price surge directly inflates 300mm fab costs by over 5% per wafer. Compounding the issue, high-purity helium supply is concentrated in the U.S. and Qatar, while export-controlled ISO containers restrict China’s ability to build buffer stocks. TSMC and Samsung will likely accelerate onshoring of gas infrastructure in the U.S. and EU, leaving mainland foundries like SMIC exposed to volatile input costs. Within 18 months, ‘gas security’ will emerge as a new competitive threshold: firms with closed-loop helium recycling or strategic supply partnerships will command significant capacity premiums. This isn’t just a cost shock—it’s an extension of geopolitical gatekeeping into advanced-node manufacturing.
