For decades, commodity investors focused on supply-and-demand fundamentals. However, the models that guided commodity investing for much of the past 30 years were built on assumptions that no longer hold: stable trade flows, predictable geopolitical relationships, reliable access to global supply chains and the belief that markets would efficiently allocate resources across borders with minimal government interference.
Consider what commodity markets have absorbed in just the past few years. China has tightened controls on exports of critical materials such as gallium, germanium, graphite and rare earths. Governments from Indonesia to Mexico have become increasingly assertive about controlling access to natural resources. Even relatively obscure inputs like sulphuric acid have become concerns as geopolitical tensions have disrupted supply chains and increased processing costs across the critical minerals sector. These developments are no longer isolated events. They are becoming a recurring feature of the commodity landscape.
For executives and investors who still think about commodities primarily through a supply-and-demand lens, the risk exposure you’re carrying may be larger than you realize.
The Map Has Changed
Geopolitical risk in commodity markets used to mean something relatively contained—a strike at a Chilean copper mine, a coup in a producer nation or a temporary export restriction that lasted a few months before markets adjusted.
What we’re seeing today is different. Countries increasingly view access to resources not simply as an economic issue, but as a strategic advantage. Control over critical minerals, processing capacity and manufacturing infrastructure is becoming intertwined with national security, industrial policy and geopolitical influence.
China’s position in many critical mineral supply chains is difficult to overstate. In rare earths alone, it dominates both processing and magnet manufacturing. Similar patterns exist across graphite, gallium, germanium and other materials that are essential to semiconductors, defense technologies and advanced manufacturing.
Having spent much of my career investing in mining and resource companies, I have noticed a subtle but important shift. Ten years ago, most conversations with investors centered on demand forecasts, project economics and commodity prices. Today, discussions increasingly focus on where materials are processed, which governments control supply chains and how quickly alternative sources can be developed if trade flows are disrupted. This is not simply a market disruption; it’s the emergence of a new geopolitical architecture around commodity flows, and many corporate and investment strategies have not fully adapted.
