The IEA has discovered a problem that anyone who’s ever ordered drill pipe or waited on a frac crew could have told them for free: supply chains concentrate, and concentration is risk. Their latest warning points out that the global energy transition rests on a handful of countries—China above all—for the processing of critical minerals and the manufacture of solar panels, batteries, and the rest of the kit.
Now, the irony here is thick enough to cut with a knife. The same institutions that spent a decade lecturing the oil and gas industry about the evils of OPEC cartels and geopolitical supply risk have built a replacement energy system that makes OPEC look like a model of diversification. At least oil can be sourced from two dozen producing nations and moved on a functioning spot market. Try that with refined graphite or polysilicon.
The IEA’s numbers tell the story: China controls the majority of refining capacity for lithium, cobalt, rare earths, and most everything else that goes into an EV battery or a wind turbine. Dominance in mining is one thing—geology is where it is. Dominance in processing is another, and that’s a policy choice the West made by shipping the dirty, low-margin work overseas and patting itself on the back for the clean balance sheet.
For investors, the practical takeaway is straightforward. Every government now promising to “onshore” critical mineral supply chains is promising capital expenditure on projects with unknown costs, long timelines, and offtake agreements that may or may not survive contact with Chinese pricing. We’ve seen this movie. Remember when rare earth mining outside China was going to boom after 2010? Most of those ventures burned cash for a decade and delivered little.
Concentration risk cuts both ways, too. China has already flexed export controls on gallium, germanium, and graphite. If you’re building an energy system whose entire supply chain answers to one capital, you haven’t diversified your risk—you’ve renamed it.
The IEA is right to sound the alarm, late as usual. The question isn’t whether the concentration exists; it’s whether Western governments will fund real mining and refining capacity at scale, or just issue more reports. Given the track record, I’d bet on the reports.
