Strengthening Project Vault: The US plan to stockpile critical minerals

The United States depends heavily on imported critical minerals, including rare earth elements, needed for semiconductors, renewable energy, AI expansion, and defense systems. Because supply disruptions could seriously harm the economy and national security, the US government has launched Project Vault, a $12 billion public-private program to stockpile emergency supplies of critical minerals. Funded by a $10 billion EXIM Bank loan and $2 billion in private capital, the project is aimed at reducing reliance on foreign suppliers, particularly China, and protecting American--and eventually allied-country--manufacturers from shortages. Project Vault's design, however, raises important questions about its durability and day-to-day operations. Key Takeaways - Unlike the Strategic Petroleum Reserve, Project Vault is designed as insurance against systemwide supply shocks, relying on private firms that pay subscription fees for access to reserves during disruptions, which makes it a hybrid of a futures market and a strategic reserve. - Voluntary participation would exclude both large self-insuring firms and small enterprises unaware of their exposure, hollowing out the risk pool in ways that could cause the program to fail when it is needed most. - Storing 60 highly differentiated minerals and processed derivatives is far more complex than stockpiling oil because supplies can degrade over time and often need to be processed to be usable during a crisis. - To be effective, Project Vault should require mandatory participation with fees scaled to firm size, fund against worst-case collective supply shocks, and prioritize processed materials over raw ore. - In the near term, building reserves of processed materials would likely depend on Chinese suppliers, making long-term investment in US and allied processing capacity critical.
