Copper and Critical Minerals Enter a Strategic Arms Race

By: Editorial Team, StoneX Media

Tue, 30 Jun 2026, 12:05

Copper and other critical minerals are increasingly being viewed through the lens of national security rather than purely industrial demand. Geopolitical tensions, supply chain disruptions and shifting trade policies are encouraging governments to prioritize long-term resource security alongside economic competitiveness. While global manufacturing activity remains subdued, competition to secure strategic mineral supply continues to intensify. This divergence is reshaping how markets value critical metals and the risks investors must now consider.

Natalie Scott-Gray, StoneX Senior Metals Analyst, has spent years analyzing global base metal markets and the interaction between macroeconomics, physical supply chains and investor behavior. Her market framework uniquely combines geopolitical developments, policy changes and fundamental analysis to explain why critical minerals are increasingly behaving as strategic assets instead of conventional industrial commodities.

Key Themes

Strategic stockpiling is becoming a structural source of demand alongside traditional industrial consumption.
Copper has become increasingly important to national industrial policy as governments seek supply security.
Geopolitical risks and trade policies are accelerating competition for long-term access to critical minerals.

Copper Becomes a Strategic National Asset

Copper is now being valued for its strategic importance rather than simply its role in industrial production. Natalie Scott-Gray notes that "the view on strategic and critical minerals is becoming more and more important", highlighting how government policy is reinforcing long-term demand expectations. Countries are beginning to compete for secure access to critical mineral supply through stockpiling initiatives, industrial partnerships and trade agreements. As resource security becomes a policy objective, copper markets may experience price support even during periods of softer economic growth.

Strategic Stockpiling Changes Market Dynamics

Strategic stockpiling is emerging as a structural force that could permanently reshape physical metal markets. Scott-Gray explains that "China has long been building up reserves" while countries including Australia and the United States are expanding similar programmes, adding that "more readily available material... will be reduced". As a result, exchange inventories may become less representative of true market availability as governments and industrial consumers increasingly compete for long-term supply. This trend could amplify price volatility whenever new geopolitical risks emerge or supply disruptions occur.

StoneX TV: Copper Hit a Record and Warehouses Are Nearly Empty

Natalie Scott-Gray, StoneX Senior Metals Analyst EMEA & Asia, breaks down the base metals week, covering copper and zinc backwardation, U.S. trade escalation with Canada, and the aluminum premium split. She works through why July Chinese economic data missed expectations and what that means for base metals demand, how the new U.S. sanctions program targeting Iranian oil could reach Chinese financial institutions, and why U.S. and Canada tariff escalation hits Rotterdam and U.S. Midwest aluminum premiums rather than global supply.

Copper and Zinc Backwardation Is Squeezing Physical Buyers Hardest

Copper and zinc are pulling away from a bearish macro backdrop, with London Metal Exchange inventories historically low and spreads tightening in both metals. The result is a physical market where the cost of waiting for metal is rising faster than the headline story suggests.

Weekly Base Metal Macroeconomic Slides

Despite increasingly weak Chinese macroeconomic data, the base metals outlook remains supported by tight physical markets, ongoing supply constraints and low inventories. Copper remains the preferred bullish exposure heading into Q4, zinc and lead continue to benefit from tightening supply conditions, while aluminium and nickel face a more mixed outlook as additional supply and policy developments create uncertainty. The balance of risks remains tilted toward continued market volatility. Financial markets continue to be shaped by a growing divergence between resilient industrial activity outside China and increasingly fragile Chinese domestic demand conditions. While physical metal markets remain exceptionally tight in several areas, investors are becoming more focused on the balance between slowing global growth signals, ongoing trade tensions, evolving tariff policy, and persistent supply-side disruptions.
