Rare earth elements are among the most strategically important raw materials of the modern economy. This group of 17 elements plays a central role in high-tech industries, clean energy technologies, digital infrastructure, defence applications and advanced manufacturing. Despite their name, rare earths are not necessarily geologically rare; the real challenge lies in economically viable deposits, complex extraction, separation and refining processes, and highly concentrated supply chains.
From electric vehicles and wind turbines to industrial motors, robotics, smartphones, medical technology, aerospace and defence systems, rare earths are essential to many technologies that shape modern life. Their importance is particularly visible in high-performance permanent magnets, where neodymium, praseodymium, dysprosium and terbium play a critical role.
As an investment theme, rare earths are gaining relevance because they sit at the intersection of technology, energy transition, industrial policy and supply security. However, they should not be viewed as simple or risk-free investments. Prices can be volatile, markets are less transparent than those for gold or silver, and liquidity, storage, quality certification and counterparty selection are important factors. For investors, rare earths may offer strategic exposure to future-oriented industries, but they require careful selection and professional structuring.

Terbium is a rare earth element from the lanthanide group and is considered one of the more strategically sensitive heavy rare earths. Its discovery dates back to 1843, when Swedish chemist Carl Gustaf Mosander identified several rare earth components from minerals associated with Ytterby in Sweden, a location historically linked to the discovery of several rare earth elements.
The production of high-purity terbium remains technically demanding because it typically occurs together with other rare earth elements and must be separated through complex chemical processes. Today, terbium is strategically relevant due to its specialised applications in high-performance technologies and its exposure to highly concentrated supply chains.
Terbium is used in selected high-value applications where its magnetic and optical properties are particularly important.
High-performance magnets: Terbium can be used as a performance-enhancing additive in neodymium-iron-boron magnets, especially where thermal stability and magnetic performance under demanding operating conditions are required.
Phosphors and display technologies: Terbium compounds have historically been important in green phosphors for lighting and display applications. While some traditional applications have declined, specialised uses remain relevant.
Special alloys and sensors: Terbium is used in magnetostrictive materials and selected alloy systems where precise magnetic or mechanical responses are required.
Terbium belongs to the heavy rare earth elements, a segment with particularly concentrated supply chains. Reliable global production data for terbium as an individual element is difficult to verify publicly, so fixed annual production figures should be treated with caution. The key market issue is not only geological availability, but the concentration of mining, separation, refining and downstream processing capacity.
China plays a dominant role across the rare earth value chain, especially in refining and magnet production. This creates supply-chain risks for industries and investors outside China. Recent export-control measures have further highlighted the strategic importance of heavy rare earths and the need for diversified supply chains.
Terbium may be attractive for investors who want exposure to strategic raw materials used in advanced technologies. Its investment case is mainly based on scarcity, specialised industrial demand and supply-chain concentration.
Value potential: Terbium’s value potential is linked to demand from high-performance magnets, advanced materials and specialised technology applications. However, price movements can be volatile and are strongly influenced by industrial demand, trade policy and supply availability.
Strategic relevance: As a heavy rare earth with specialised applications, terbium is relevant for industries that depend on high-performance magnetic materials.
Portfolio diversification: In a professionally structured commodity allocation, terbium can serve as a niche addition beyond traditional precious metals, but it requires careful attention to market access, quality and liquidity.
For investors, terbium represents a highly specialised rare earth investment with strategic relevance, but also with higher complexity than classic precious metals.

Dysprosium is a heavy rare earth element with a silver-grey metallic appearance. It was discovered in 1886 by French chemist Paul-Émile Lecoq de Boisbaudran. Its name derives from the Greek word “dysprositos”, meaning “hard to obtain”, which reflects the difficulty of isolating the element.
Today, dysprosium is particularly important because it can improve the high-temperature performance of permanent magnets. This makes it relevant for electric vehicles, wind turbines, industrial motors and other demanding applications where magnets must remain stable under heat and stress.
Dysprosium is used in several high-tech and industrial sectors.
Permanent magnets: Dysprosium is used in certain neodymium-iron-boron magnets to improve temperature resistance and magnetic stability. This is especially important in applications such as electric drive systems and wind power generators.
Nuclear technology: Because of its neutron absorption properties, dysprosium has selected applications in nuclear technology and control materials.
Special lighting and optical applications: Dysprosium compounds have been used in high-intensity lighting and specialised optical systems, although magnet applications are currently more strategically important.
Dysprosium supply is closely tied to heavy rare earth production and separation. Publicly verifiable global production figures for dysprosium as an individual element are limited, so precise annual production claims should be avoided unless a specific verified source is provided.
The broader market is shaped by supply concentration, complex processing requirements, export controls, growing demand for high-performance magnets and efforts by industrial countries to diversify rare earth supply chains. Dysprosium is one of the elements that receives particular attention because it is difficult to substitute in demanding magnet applications.
Dysprosium offers investors exposure to one of the most strategically important heavy rare earths.
Value potential: Demand for dysprosium is closely linked to high-performance magnets used in electric mobility, wind power and industrial automation. At the same time, the market can be volatile and sensitive to geopolitical developments.
Strategic importance: Modern high-performance technologies depend on dysprosium where magnets must withstand elevated temperatures and demanding operating conditions.
Diversification: As part of a broader rare earth or critical metals strategy, dysprosium can complement traditional commodity and precious metal investments.
Overall, dysprosium is a technologically important but specialised raw material. It may offer strategic investment potential, provided investors understand the market’s liquidity, price and supply-chain risks.
