Keypoints:
- US rare earth stockpile reportedly down to two months
- DRC, Botswana and South Africa seen as potential suppliers
- Global race intensifies for critical minerals supply
AFRICA’S mineral-rich economies are drawing renewed strategic attention after reports suggested the United States may have only two months’ worth of rare earth elements left in its defence stockpile, a development that could intensify Washington’s search for alternative suppliers.
Countries including the Democratic Republic of Congo, Botswana and South Africa are emerging as potential partners as the United States and other Western governments attempt to reduce reliance on dominant suppliers in the global rare earth market.
Rare earth elements are essential components in a wide range of technologies, from advanced military systems to electric vehicles, wind turbines and consumer electronics. Ensuring secure access to these minerals has therefore become a major national security priority for several governments.
Washington faces supply vulnerability
According to reporting by the South China Morning Post, citing sources familiar with the matter, the United States may have only around two months of rare earth inventory available for military use. The report highlights growing concern in Washington that heavy reliance on foreign supply chains — particularly those linked to China — could expose critical defence manufacturing and advanced technology sectors to supply shocks.
As policymakers search for alternative sources of these strategic minerals, resource-rich regions such as Africa are increasingly being viewed as potential partners in efforts to diversify global rare earth supply. Rare earths comprise a group of 17 metallic elements used in powerful magnets, batteries, radar systems and guided missile technologies. They are critical components in missile guidance systems, fighter aircraft and military communications infrastructure.
Despite having some domestic production, the United States still relies heavily on international supply chains to process and refine these minerals. This dependency has become a growing strategic concern for policymakers as geopolitical tensions and export restrictions reshape global mineral markets.
China’s dominance reshapes global markets
One of the central drivers behind the scramble for alternative supply sources is China’s dominance of the rare earth sector.
China controls much of the world’s processing capacity for rare earth minerals and has previously imposed export restrictions on several strategic materials, heightening fears in Western capitals about potential disruptions to defence and technology industries.
Recent supply shortages have already affected parts of the aerospace and semiconductor sectors in the United States, where companies depend on rare earth materials such as scandium and yttrium used in advanced electronics and defence technologies.
These pressures have prompted Washington and its allies to accelerate efforts to diversify supply chains and reduce reliance on Chinese-controlled mineral processing.
Africa’s mineral wealth gains importance
Africa has increasingly emerged as a key frontier in the global search for critical minerals.
The Democratic Republic of Congo, Namibia, Tanzania and Zimbabwe all hold significant reserves of strategic resources needed for modern energy systems and high-tech manufacturing. Botswana and South Africa also possess substantial mining sectors capable of supporting new rare earth exploration projects.
Africa’s mineral resources are already attracting significant international interest. Analysts say the continent’s vast reserves of cobalt, manganese and rare earth elements position it as a critical player in the global energy transition and emerging supply chains.
For example, large mining projects across the continent are expected to drive investment as demand grows for the minerals required to power renewable energy technologies and advanced electronics. Africa Briefing previously reported that Africa’s vast mineral reserves could play a major role in supporting global energy transition supply chains.
A global race for critical minerals
The competition for rare earth elements forms part of a broader geopolitical contest over the resources needed to power the next generation of industrial technologies.
Demand for critical minerals such as lithium, cobalt and rare earth elements is expected to rise sharply over the coming decade as countries expand renewable energy capacity and accelerate the shift towards electric vehicles and digital infrastructure.
At the same time, governments are increasingly viewing access to these resources through the lens of national security and geopolitical competition.
As global powers scramble to secure reliable supplies, Africa’s mineral wealth is placing the continent at the centre of a new strategic race for the raw materials that will shape the future of the global economy.
