China’s Control Over Germanium: A Geopolitical Strategy
In recent years, China has been establishing a comprehensive network of power through critical minerals, transitioning from *rare earths* to *copper* and now *germanium*. Though the name ‘germanium’ may not resonate with the general public, this metal is pivotal for the defense industry , playing a critical role in technologies ranging from night vision systems in fighter jets to satellites. In addition, it is integral to the optical fibers that underpin the Internet . Today, the germanium market has nearly collapsed, with prices soaring fivefold within two years, driven primarily by Beijing’s actions .
The Origin of the Crisis
Two years ago, China implemented stringent controls on the export of germanium, gallium, and antimony, citing the restrictions enforced by the *United States* and the *Netherlands* on advanced semiconductors. However, the most significant blow came at the end of 2024 when germanium exports plummeted, cutting off supply for many merchants. Terence Bell from *Strategic Metal Investments* shared with the Financial Times that just six months ago, he managed to purchase a gram of germanium at a reasonable rate. “The situation is desperate,” he remarked. Aaron Jerome from *Lipmann Walton & Co* described the current state of the market as “devastated,” noting that what used to be a purchase of 100 kilos had dwindled to a mere 10 kilos, now at a tripled cost.
Quantifying the Collapse
The figures confirm the collapse. An analysis by *Policy Accelerator Silverado* cited in the *Financial Times* reveals a staggering 40% drop in germanium imports to the United States from China between January and July of this year. Prices have skyrocketed from around $1,000 in 2023 to nearly $5,000 in September 2023, hitting levels unseen since 2011.
The Strategic Role of Germanium
The significance of germanium stems not from its geological rarity but rather its challenging extraction process, as it is mainly acquired from coal and zinc byproducts. Its military applications are irreplaceable, particularly in thermal imaging systems used within fighters, drones, and satellites.
In civil applications, it is critical for optical fiber, solar panels, and chips. Analyst Caroline Messecar emphasized in the *Financial Times* that finding substitutes for germanium would necessitate complete redesigns, leading to unacceptable precision losses in military usages.
Based on estimates from the *Fastmarkets agency*, global demand for germanium stands at roughly 180-200 tons annually.
Beijing’s Geopolitical Strategy
In recent years, Chinese authorities have increasingly politicized the trade of critical minerals. By the end of 2024, they not only restricted exportation of germanium but also of gallium and antimony to the United States, later adding scandium and dysprosium—elements crucial for chips and telecommunications.
China’s approach aims to monopolize the entire supply chain of these critical minerals. While holding only 4% of the world’s copper reserves, for instance, it controls a staggering 49% of global refining. “Rather than merely amassing raw materials, China is creating intentional bottlenecks within the supply chain,” as stated in xataka. The situation is similar with tungsten, where China controls 83% of the supply, leading to a 55% price surge following the tightening of export controls in February 2025.
To put it simply, Beijing aims to be indispensable, fashioning itself into a gatekeeper for strategic metals vital for the 21st century. However, this power comes with caveats; it is still reliant on imports of concentrates from countries like Chile , Peru , and Mexico . Should any of these partners reconsider their positions—especially with Mexico having already imposed 50% tariffs on Chinese products—it could jeopardize China’s crucial supply lines. Additionally, some of China’s copper operations are operating at negative margins, forcing certain enterprises to close down.
A Race Against Time
Major consumers of germanium are hastily working to adapt to these constraints. In the United States, major defense contractor *Lockheed Martin* signed an unprecedented agreement with *South Korea Zinc* to secure supplies. Meanwhile, *Lightpath Technologies*, backed by the government, is pursuing alternative optical solutions. However, Sam Rubin of Lightpath cautions, “No one will redesign existing systems unless absolutely necessary.”
Unfortunately, viable alternatives are still scant. *Umicore* in Belgium and *Teck Resources* in Canada produce limited amounts of germanium, insufficient to meet the escalating demand. Germany has already warned that a prolonged crisis could halt production within its automotive industry. The European Chamber of Commerce is even appealing to Beijing to release supplies for chip manufacturers.
Russia, a historical supplier, has been largely sidelined due to international sanctions following the Ukraine conflict. Previously a significant provider of germanium to the West, Russia now directs its production to China and non-sanctioned countries. This shift has intensified Beijing’s control over germanium supply during a time of heightened demand.
Investigating Future Solutions
In Germany, researchers at the *Technical University of Freiberg* are exploring innovative methods for extracting germanium from plants post-fermentation during biogas production. Although the current yield is only milligrams per liter, their goal is to reach a gram, which could pave the way for more sustainable and local production methods.
Final Thoughts
Germanium has rapidly transformed from a relatively obscure mineral to a cornerstone of global strategy, emphasizing its significance in the context of geopolitical power dynamics . As noted by the *Financial Times*, while the demand continues to climb, supply is dwindling. This evolving landscape clearly illustrates one fundamental truth: in a world increasingly reliant on electrification and militarization, the capacity to control critical minerals equates to political power .
