For more than a year, Perky has noticed frequent mentions in the news about a commodity called rare earth. The author feels greater clarification regarding this concept might be useful and interesting for readers.
Rare earth elements are a group of 17 chemically similar metals essential to modern technology. First identified in the late 18th century, they remained largely confined to scientific and industrial use for most of the 20th century.
Their profile rose from the 1980s as high-tech applications expanded, but they have only become truly mainstream in the past decade, driven by clean-energy growth, geopolitical tensions, and supply-chain concerns.
Nowadays, it must be appreciated that rare earth elements power everything from smartphones and electric vehicles to wind turbines and advanced military systems.
Most of the world’s rare earth elements are mined and processed in a handful of countries, with the dominant position held by China. The latter accounts for around 70% of global rare earth mining and more than 90% of the world’s refining and processing capacity.
The rare earth supply chain has become a high-stakes arena and extracting the raw ores is only part of the story. The full value comes from separation, purification, refining, and manufacturing into magnets and specialty components.
China has deliberately invested across this whole chain since the 1980s, giving it a head-start others find hard to match. Because so much of the refining and manufacturing occurs in China, even mines elsewhere must often send material to China for processing.
That gives China considerable leverage and makes non-Chinese firms vulnerable to export restrictions, or regulatory changes. At the same time, environmental, regulatory and cost challenges make new mines and refineries slow to build, so supply growth is hard to scale.
As a result of these factors, access to rare earths has become a battlefield of global competition. Companies and governments are now scrambling to secure mines, build processing capacity, and reduce dependence on any single dominant supplier.
The intense competition for rare earths is reshaping global economic and political balances. Countries and companies are working to develop rare-earth mines, processing facilities, and supply agreements outside China, so that this country is not relied upon as a main source for other countries.
If these alternative sources grow successfully, for example in Australia, the United States, Europe, and parts of Africa, China would supply a smaller share of the world’s rare earths. This would give other nations more control and reduce the risk of disruption if China restricts exports or changes policy.
Perky is now having to appreciate that a commodity once obscure in public discussion now sits at the heart of industrial strategy and geopolitics.
