Executive Summary
The West is actively building a critical minerals supply chain independent of China, which historically controlled over 90% of processing, framing it as a matter of national and economic security.
The primary bottleneck is not a scarcity of raw minerals but a global concentration of processing capacity in China.
The strategy involves diversifying both mining sources (e.g., Latin America) and processing locations (e.g., US, France).
Public-private partnerships are emerging as a key catalyst.
government funding and due diligence, like the $1.6 billion CHIPS Act letter of intent for USA Rare Earth, are de-risking investments and attracting significant private capital.
Latin America, with massive untapped rare earth and lithium deposits in countries like Brazil, Argentina, and a potentially normalizing Venezuela, is positioned to become a crucial upstream supplier for the Western Hemisphere.
