The Iran war is tightening global tech supply chains by cutting off helium from Qatar, a key source of the gas used in advanced industries like chipmaking. Qatar halted production after the conflict erupted. This week, more strikes damaged Qatar's main facility. Experts say spot helium prices have already doubled. They say shortages take weeks to show up because shipments move slowly. Chip factories use helium to cool and protect wafers, and they have no easy substitute. Hospitals also need it for MRI machines.
