Critical Mineral Scarcity

Critical mineral scarcity is the challenge of securing the raw materials that modern technology depends on, from the rare earth elements in electric motors and wind turbines to the lithium and cobalt in batteries. These minerals are not scarce in the sense of running out globally, but their supply chains are concentrated in a small number of countries, and mining and processing capacity elsewhere is limited. That concentration creates risk for any nation that relies on imports for materials it considers essential to its economy and defense.

Supply chain dependence shapes much of the policy debate in this area. The United States imports most of the processed critical minerals it uses, and a large share of global refining capacity sits in a handful of countries, with China playing an outsized role. This dependence raises questions about what happens if trade relationships sour, if export controls tighten, or if a supplier prioritizes its own industries. The strategies the government has pursued to reduce this exposure, and the obstacles those strategies face, are explored in Critical Minerals: US Strategy to Break China’s Supply Chain Dominance.

Defense and technology needs add urgency to the issue, since many critical minerals have no readily available substitutes in advanced electronics, weapons systems, and clean energy equipment. Building new domestic mines, processing plants, or recycling capacity takes years and faces environmental and permitting hurdles, which means shortages or price shocks can arrive faster than new supply can respond.
