Highlights
- The UK is creating a standalone category for rare earths and critical minerals in its national security investment review process.
- Despite no domestic rare earth mines, the UK aims to control global critical mineral investment flows through regulatory oversight.
- The new regulations focus on strategic control of mineral supply chains, particularly materials critical for defense technologies.
JD Supra’s recent article (opens in a new tab) on the UK’s proposed reforms to the National Security and Investment Act (NSIA) frames the news as a breath of fresh air for dealmakers. And yes—routine corporate reorganizations and benign insolvency actions are being removed from mandatory filing triggers. But buried in the Cabinet Office’s legalese is a quiet revolution: rare earth elements and critical minerals are finally being carved out as a standalone category of national security interest.
That’s not a footnote—it’s a flashing geopolitical signal.
Rare Earths Get Their Own Gate
For the first time, rare earths, lithium, cobalt, and other defense-critical materials are being separated from the broader “Advanced Materials” category under the NSIA. This matters. It means that companies involved in the extraction, processing, refining, or even recycling of these materials could face mandatory UK government review when foreign entities come knocking.
The UK—despite having no rare earth mines of its own—is positioning itself as a regulatory chokepoint for critical mineral assets. Whether it’s Chinese interests buying into a Chilean ionic clay project or U.S. investors looking at Australian neodymium oxide processing facilities, London wants a seat at the table.
Legal Clarity, Strategic Ambiguity
JD Supra’s analysis, co-authored by Paul Hastings LLP, is surgically precise from a compliance standpoint. But it reads like it was ghostwritten by a mergers-and-acquisitions algorithm. Nowhere does the article grapple with why the UK is shifting course, or how these new powers will apply in a world where mineral supply chains are murky, offshore, and often indirect.
Where are the questions about shell structures, joint ventures, tolling agreements, or state-backed intermediaries? How will the UK distinguish between passiveinvestors and strategic operators—especially in rare earths, whereofftake contracts can be more powerful than outright ownership?
Critical Minerals: National Security’s Quiet Front Line
Rare earths—especially heavies like dysprosium and terbium—aren’t just exotic materials. They’re the linchpins of fighter jet engines, satellite servos, submarine navigation systems, and hypersonic missile actuators. As REEx’s latest HREE rankings show, 98% of the world’s supply is controlled by China and Myanmar. The West’s challenge isn’t just mining more—it’s controlling the flow of capital, processing, and intellectual property.
That’s why these NSIA reforms—if enforced with resolve—could be powerful. The UK might not mine rare earths, but it can set red lines on who gets access to the capital stack of companies that do.
Final Verdict: Good Start, Now Get Serious
The UK’s move to isolate critical minerals within its investment screening regime is overdue—but welcome. Yet the real test lies ahead: Will these powers be used to protect real supply chain resilience, or merely to generate regulatory paperwork?
JD Supra’s write-up is accurate but uncritical. Investors, policymakers, and strategics would be wise to look past the streamlining rhetoric and ask the harder question:
What good is a sharper scalpel if no one’s willing to wield it?
