Rare, Rarer, RarestCritical minerals encompass a wide range of naturally occurring elements and minerals, such as lithium, cobalt, nickel and copper. These minerals are essential in the production of everyday items, including batteries and electrical wiring, as well as in industrial applications such as energy storage systems and military electronics.Even less exotic materials now fall into this category. In November 2025, the US Geological Survey added silver to the critical minerals list for the first time, just weeks before China imposed a complete ban on silver exports that led to a fourfold increase in silver prices.Rare earth elements, which fall under the umbrella of critical minerals, play a pivotal role in green energy projects and defence manufacturing, as magnets made from these elements are a key component of electric motors, wind turbines, aircraft engines and generators.The public sector is recognising the importance of private companies in meeting the increasing demand for critical minerals. In 2025, the Pentagon became the largest shareholder in MP Materials, the only fully integrated producer of rare earth magnets in the US.China added MP Materials and USA Rare Earth, as well as eight other US entities it said are linked to the US military, to its export-control list in retaliation for Washington placing several Chinese companies under restrictions this month https://t.co/CK4xXDZZal pic.twitter.com/4LkonZz3hS— Reuters (@Reuters) June 22, 2026Data centres require a wide range of critical minerals to function, while a standard electric car requires about six times more mineral inputs than a similar vehicle with a conventional internal combustion engine. JP Morgan Global Research forecasts that global demand for lithium will grow by 16% this year, most of which will be driven, if you will pardon the pun, by electric vehicle production.Related: Retail Investors Shift to Energy, Rare Earths, and AI Amid TensionsAs demand for green energy solutions increases, demand for lithium will rise accordingly, potentially creating a market deficit. The supply chain for critical minerals and rare earths is already highly concentrated, with China supplying upwards of 90% of refined rare earths and magnets.One of the reasons for China’s dominance of the rare earths market is that, in addition to its own reserves, it has acquired production facilities in Africa, from which minerals are shipped back to China for refining.“This level of control has made pricing very difficult and encouraged the US government to introduce floor pricing for the only rare earth mine in that country and make a huge investment in it,” observes Ivan Murphy, Executive Chairman of Harena Rare Earths. “But even within that opportunity for MP Materials, the majority of what it produces in California is light rare earths.”The Price Is RightThe upside for producers is that customers are supply-sensitive rather than price-sensitive, which is clearly good news for companies such as Harena Rare Earths, especially with the UK forming its own critical minerals strategy.“While the current critical minerals supply chain is concentrated in the Asia Pacific, there are opportunities for growth and expansion across regions,” says Bill Peterson, Head of Clean Tech and Metals & Mining Research at JP Morgan.The high concentration in the market creates a significant risk of supply chain disruption, translating into increased price volatility, says Juliette Fortin, Senior Managing Director in the Economic Consulting segment at FTI Consulting.“Supply-demand imbalances also impact volatility, with global demand responding to the energy transition,” she says. “Rare earth prices have been highly volatile since 2019, with a peak in early 2022 driven by post-COVID demand and rapid EV and battery growth.”Supply growth for battery metals stabilised prices in 2024 and early 2025, until China’s export restrictions in April 2025.Other factors affecting access to critical minerals include the risks associated with committing substantial long-term capital across multiple jurisdictions, as well as lengthy permitting and development timeframes in Western countries.“Lithium remains constrained, not because of resource scarcity but because bringing new, high-quality supply online takes time and capital,” observes Tony Sage, Chairman and CEO of Critical Metals Corp. “Volatility is inherent in the sector. Lithium prices rose sharply and then corrected by more than 70% in a relatively short period, and similar cycles have played out across nickel, cobalt and other critical metals. From our perspective, that reinforces the need to focus on long-term fundamentals rather than short-term price cycles.”The solution is not to chase pricing cycles but to advance high-quality assets that remain competitive across cycles. That means prioritising resource quality, favourable jurisdictions and proximity to end markets so that projects are economically viable and strategically relevant throughout the full commodity cycle.A Virtuous CycleRecycling has emerged as a key strategy for increasing the supply of lithium. “When we think about key components of common battery chemistries, it isn’t so much about them being difficult to access as it is about ensuring that our sourcing is diversified enough,” explains Claire Zirkelbach, CFO of battery recycling materials and management company Cirba Solutions.Recycled materials recovered from manufacturing scrap, end-of-life batteries and electronics provide a complementary, often more localised, supply stream that can reduce dependence on primary extraction, shorten supply chains and buffer against market fluctuations.Closed-loop systems that include collection networks and partnerships with battery recycling infrastructure help capture those materials already in circulation, effectively turning waste into a strategic resource and reinforcing a more resilient and secure critical minerals supply chain.Fastmarkets estimates that around 8% of global battery metal supply will come from battery recycling this year. Secondary content can help close the gap between supply and demand because these recycled battery materials can be used repeatedly.It is clear that critical mineral producers offer scope for considerable returns. However, investors need to be aware that, according to the Critical Minerals Institute, the speed of deal-making in critical minerals is outstripping the necessary technical due diligence in some cases.Given the importance of geological complexity, processing skills and operational expertise in this sector, such lapses can lead to serious consequences for project success and investor confidence.
