Rare earth metals have emerged as a promising investment opportunity in recent years. Sporting unique properties, these metals are used in many industries sparking investor interest.
This article discusses rare earth metals and why investors may think about adding them to a portfolio.
Understanding Rare Earth Metals
Rare earth metals, also known as rare earth elements (REEs), are a group of seventeen chemical elements. Despite their name, these metals are not actually rare in terms of abundance in the Earth's crust. However, they are found in low concentrations, making their extraction and processing challenging and expensive.
What makes rare earth metals unique is their exceptional magnetic, electrical, and optical properties. These characteristics have made them integral to the production of a wide range of modern technologies, such as smartphones, electric vehicles, wind turbines, and advanced medical equipment.
The growing trend towards electrification in transportation and energy sectors is driving increased demand for rare earth metals.
In turn, this surge in demand has led to concerns about the sustainability of rare earth metal mining and the environmental impact of their extraction.
China is the largest producer of rare earth metals, accounting for a significant portion of global supply. This dominance has raised geopolitical concerns, as many countries are seeking to diversify their rare earth metal sources to reduce dependency on a single supplier.
What are Rare Earth Metals?
Sixteen of the 17 rare earth elements are included in a Department of Energy (DoE) Federal Register list of critical minerals, highlighting their economic significance and risk of supply interruptions. The only one not to make the list is Promethium.
The rare earth elements, consist of the lanthanide series (elements with atomic numbers 57 to 71) and two other similar elements.
The first element in the group of rare earth metals is lanthanum. The full list is as follows:
Lanthanum (La)
Cerium (Ce)
Praseodymium (Pr)
Neodymium (Nd)
Promethium (Pm)
Samarium (Sm)
Europium (Eu)
Gadolinium (Gd)
Terbium (Tb)
Dysprosium (Dy)
Holmium (Ho)
Erbium (Er)
Thulium (Tm)
Ytterbium (Yb)
Lutetium (Lu)
Additionally, scandium (Sc) and yttrium (Y) are often included in the rare earth category due to their similar properties and occurrence in the same ores.
Why Investors Should Care About Rare Earth Metals
An increasing demand for rare earth metals, coupled with limited supply, has created an attractive investment opportunity. As the world transitions towards cleaner energy sources and digital technologies continue to advance, the demand for rare earth metals is expected to continue rising.
Furthermore, rare earth metals have a diverse range of applications in key industries, including electronics, renewable energy, defense, and healthcare. This widespread reliance on rare earth metals ensures a sustained demand for these commodities, thereby making them an intriguing investment option.
One of the most significant factors driving the interest in rare earth metals is their use in the production of electric vehicles (EVs).
Neodymium and dysprosium, two rare earth elements, are essential for the manufacturing of high-performance magnets used in electric vehicle motors. With the global automotive industry shifting towards electric mobility to reduce carbon emissions, the demand for rare earth metals is projected to continue to rise in the coming years.
Moreover, the geopolitical dynamics surrounding rare earth metals add another layer of complexity to their investment appeal. China currently dominates the global rare earth market, accounting for a significant portion of both production and reserves. This concentration of supply raises concerns about supply chain security and potential disruptions, further emphasizing the strategic importance of diversifying rare earth metal sources for investors seeking stability in their portfolios.
