Competition for critical minerals shifts to controlling "existing flows": Australia's strategic window and supply chain challenges

Critical Minerals Competition Shifts to Controlling "Existing Flows": Australia's Strategic Window and Supply Chain Challenges

This week, a subtle yet significant signal emerged in the copper market on the London Metal Exchange: the premium of spot prices over three-month contracts (backwardation) widened to approximately $434 per ton, a five-year high; August contracts were once $370 higher than September contracts. At the same time, exchange inventories fell for the 42nd consecutive trading day. The "immediate availability" of copper is becoming a scarcer resource than the copper price itself. Shortly after, the Democratic Republic of the Congo announced a ban on exports of copper and cobalt concentrates, and European erbium prices have risen by more than 50% since June—the bull-market logic for critical minerals is shifting from "locking up future deposits" to "controlling current flows."

For Australia, this shift carries both warnings and opportunities. As a major global supplier of iron ore, lithium, copper, and rare earths, Australia has resource endowments but has long been weak in processing and refining. When China uses export controls as a strategic tool, the DRC promotes domestic processing through bans, and the United States reshapes supply chains with nearly $40 billion in financing, whether Australia can upgrade from "miner" to "manufacturer" will determine its resource economy status for the next decade.

The Copper Lesson: Resources Are Not the Same as Supply Chains

The current squeeze in the copper market is not a mineral shortage but a geographic mismatch of "deliverable metal." Expectations of U.S. tariffs have attracted metal to the United States, inventories in China have tightened, and arbitrage funds have withdrawn from warehouses that typically balance regional deficits, splitting the global market into several regional pools. Data from the International Energy Agency (IEA) reveals a deeper problem: between 2005 and 2025, China contributed more than 90% of global copper smelting capacity growth, raising its share from about 15% to 50%; meanwhile, smelting capacity utilization outside China has fallen below 70%. This means that even if the West continues to develop new mines, as long as processing remains highly dependent on China, the "deliverability" of supply cannot truly be secure.

The DRC's ban further reinforces this lesson. Most Congolese copper is already exported as refined cathodes, and cobalt as hydroxide, so the direct supply losses from the ban may be limited. But it has pushed up prices in an already tight spot market. More importantly, it shows that producer-country governments are using "ore leverage" as an industrial policy tool. Similar policies in Zambia, Indonesia, and other countries have already confirmed this trend.

Rare Earths: Small Market, Big LeverageThe rare earth market demonstrates a more concentrated leverage effect with a smaller size. Since June, erbium prices in Europe have risen by more than 50%, domestic prices in China by about 40%, and precautionary buying has also appeared in heavy rare earths such as holmium and ytterbium. Erbium is used in fiber-optic communications, lasers, and AI data center infrastructure, with demand growing rapidly. The root cause of the price increases is not an actual supply disruption, but rather buyers accumulating inventories before China's export control suspension period expires on November 10. As Jack Lifton, co-chairman of the Critical Minerals Institute, put it, November 10 is "not simply an export control deadline, but a day for the West to test whether it has built something China cannot disrupt."

China's plan to expand mining capacity at the Bayan Obo mine highlights the sophistication of its industrial policy: mining capacity is slated to increase by 50%, but the main product is iron ore, with rare earths remaining under quota management as a byproduct. China can independently adjust mining, quotas, processing, domestic allocation, and export licensing, both supporting domestic manufacturers and retaining the option of external restrictions. This "deep reserve" capability goes far beyond simple supply restrictions. The lesson for Australia is that expanding the scale of mining alone cannot break through China's processing barriers.

Enforcement Risk Becomes a New Variable

The intensity of export control enforcement has become a major compliance risk for multinational companies. Chinese authorities have reportedly detained several Japanese citizens, including executives of companies operating in China, in investigations involving export violations of dual-use items. Offices have been searched, and employees have been questioned. For multinational manufacturers in the critical minerals sector, risks have expanded from shipment delays to personnel safety, internal controls, and customer due diligence. This will increase the cost of doing business for foreign enterprises in China, but it may also prompt more companies to seek supply sources outside China, creating substitution opportunities for Australia and allied countries.

Australia's Opportunity: A "Negotiating Network" from Resources to Processing

The cooperation model between Malaysia and Australia deserves attention. Lynas Rare Earths and South Korea's JS Link plan to build a plant with an annual output of 3,000 tonnes of sintered NdFeB magnets near Lynas's Kuantan plant in Malaysia. Lynas will invest A$50 million, with raw material supply arrangements continuing until 2038. This model combines Australia's resources and processing capabilities, South Korea's magnet expertise, and Malaysia's industrial site and policy approvals, demonstrating that allied supply chains will not be entirely domestic but rather a "negotiating network of specialized jurisdictions."

• For Australia, this means it must seize several windows:
• Leverage the existing resource base to attract overseas capital and technology to build midstream separation and refining capabilities.
• Sign bilateral agreements with allies such as Japan, South Korea, and the United States, similar to the U.S.-Japan mining framework, but with greater emphasis on onshore processing in Australia.
• Provide certainty in regulation and financing for critical mineral projects, avoiding the U.S. predicament of "large announcements, slow delivery."The White House claims that since January 2025, it has signed or approved 160 mining deals worth nearly $40 billion in total, but analysts point out that these projects are at different stages of technological maturity and financing. Public capital can bear risks that the private market is unwilling to take, but it cannot shorten engineering timelines. Australia needs to learn this lesson: project approval does not equal capacity coming online.

Long-term trend: the next decade is a race in processing capacity

Over the medium term, the global critical minerals system will evolve into several regional blocs: China and its partner countries will maintain their advantages in raw materials and processing; the United States will build selective alternative supply chains through massive investment; Japan is betting on long-cycle options in deep-sea mining; and Australia, Malaysia, and other middle powers will embed themselves in new networks through specialized division of labor. A "China substitute" cannot emerge in the short term, but a mosaic of "non-China options" can take shape.

• For Australia's resources industry, the following changes may occur over the next 3–10 years:
• Price volatility for minerals such as copper, rare earths, and lithium will be driven by trade policy rather than supply-demand fundamentals, requiring mining companies to strengthen inventory and logistics management.
• Downstream processing capacity is becoming a national strategic asset. If Australia cannot develop smelting and refining domestically, it will remain exposed to supply chain risk.
• Within the Asia-Pacific trade landscape, capital and technology from Japan, South Korea, and India may accelerate their flow into Australia's critical minerals processing projects in exchange for stable supply.

Conclusion

The critical minerals bull market has shifted from "owning mineral deposits" to "controlling flows." Copper squeezes, the DR Congo's ban, and the scramble for rare earths are all footnotes to this transformation. Australia has world-class resource reserves, but its true strategic value lies in whether it can convert ore into intermediate and finished products that meet commercial specifications. As Jack Lifton put it, mineral deposits, subsidies, and press releases do not make a supply chain. Only by achieving commercial-scale production across mining, separation, refining, and manufacturing can a country gain a voice in the global critical minerals race. For Australia, the window is closing—but it is not yet closed.

This requires unprecedented coordination among government, industry, and allies. From the exemption precedent at Kamoa-Kakula, to the magnet partnership between Lynas and JS Link, to the US–Japan deep-sea rare earth program, all successful cases show that the future of critical minerals belongs to countries that can connect resources, technology, capital, and political permission into a true supply chain. Australia can be one of them—but it must start acting today.
