The Biden administration's $12 billion Project Vault to stockpile critical minerals is raising concerns about triggering a global resources arms race. The initiative aims to secure supplies of lithium, cobalt, and rare earth elements vital for clean energy tech and defense systems, as Western nations work to reduce dependence on Chinese-dominated supply chains.

Analysts caution that large-scale government stockpiling could fragment international efforts to build sustainable mineral markets. China currently controls 80-90% of processing for key green energy metals, prompting Western governments to pursue alternative strategies through programs like the US Inflation Reduction Act.

The stockpile plan comes as demand for battery minerals is projected to grow sixfold by 2040. While supporters argue strategic reserves ensure manufacturing stability, critics warn national hoarding could distort prices and slow the energy transition by discouraging private sector investment in new mining projects.
