Material matters

Baillie Gifford is an Edinburgh investment partnership founded in 1908, famous for ultra-long-horizon, high-conviction growth investing — its early stakes in Amazon, Tesla and NIO are classics. Its "actual investors" philosophy holds world-changing companies on 5-10 year views; AUM is around $120bn. The Insights column carries its managers' investment views and thematic research.

In plain words

This report says global supply chains are fragile, making resource scarcity a key investment theme. The fund (Baillie Gifford) is optimistic, betting on energy and materials. It highlights three holdings: Epiroc (mining equipment, like selling shovels in a gold rush), Martin Marietta (crushed stone, with a local monopoly due to high transport costs), and Freeport-McMoRan (copper mining, benefiting from surging demand for EVs and AI).

At a Glance

One-sentence summary: Global supply chain vulnerabilities are intensifying, making resource scarcity a core investment theme, as the portfolio shifts from technology toward beneficiaries of energy and resource bottlenecks. [Optimistic]

  • The author opens with a complaint from a copper merchant in 1750 BC, drawing a parallel to modern supply chain fragility, and emphasizes that under supply-demand mismatches, commodities can also create immense value.
  • The portfolio holds long-term positions in Epiroc (mining equipment) and Martin Marietta (aggregates), benefiting from the "picks and shovels" logic of the "modern gold rush."
  • Since the start of the year, new purchases include Tidewater, EQT, and Freeport-McMoRan, directly betting on supply-demand imbalances in energy and copper.
  • The article cites research suggesting that global copper demand over the next 22 years will exceed the total of the past 5,000 years, yet only four major copper deposits were discovered between 2019 and 2023.
  • Uranium and rare earths are identified as the next research priorities, with the report arguing that AI, geopolitics, and electrification are reshaping supply chains.

An Ancient Copper Merchant’s Complaint Reveals the Fragility of Modern Supply Chains

The article opens by citing a customer complaint from 1750 BC against the copper merchant Ea-nasir, noting that securing high-quality copper supply has always been a challenge. The author argues that over the past 40 years, technology has taken center stage, and Western investors have grown accustomed to businesses built on "code rather than copper." The global division of labor has pushed resource extraction to the lowest-cost regions, but this system has sacrificed resilience for efficiency. The author states: "What the global economy gained in efficiency through this new division of labour, it lost in resilience and security." The pandemic, the war in Ukraine, the US-China trade war, and conflicts in the Middle East have exposed the fragility of global supply chains, revealing that the supply of commodities—from sunflower oil to natural gas—can depend on a handful of, sometimes hostile, nations. Growth investors are rediscovering a forgotten truth: in cases of structural supply-demand mismatches, even commodities can generate enormous value.

Investing in the "Picks and Shovels" of the "Modern Gold Rush": Epiroc and Martin Marietta

The portfolio has long held two companies benefiting from the theme of resource scarcity: Swedish mining equipment maker Epiroc and US construction materials supplier Martin Marietta Materials.

  • Epiroc: Held since its spin-off from parent company Atlas Copco in 2018. The author believes that in a "gold rush" for multiple commodities simultaneously, selling cutting-edge mining equipment holds genuine value. The company benefits from several structural trends: stricter emissions regulations, rising wage and fuel costs, declining ore grades, and miners exploring deeper underground. By automating dangerous underground operations and replacing diesel machinery with electric equipment, Epiroc helps miners reduce accidents, emissions, fuel costs, and labor intensity.
  • Martin Marietta Materials: This aggregates and construction materials supplier holds a unique advantage. Aggregates (crushed stone) are not inherently scarce, but their selling price is only about $23 per ton, making the cost nearly negligible for any large infrastructure project. The key lies in transportation costs: The author states: "after 30 or 40 miles, the cost of transport begins to swamp the cost of the rocks themselves." This creates a "hyper-local monopoly," allowing producers to raise prices gently year after year, while customers, facing multi-million-dollar construction projects, have little objection to paying an extra $2 per ton.

Portfolio Shifts Toward Energy and Resource Bottlenecks, with a Focus on Copper, Uranium, and Rare Earths

Beyond the two companies above, the portfolio has recently pivoted to address broader strategic and economic bottlenecks, increasing exposure to the energy and resource sectors.

Since the beginning of the year, new purchases include:

Company Business Investment Thesis
Tidewater Operates offshore service vessels for oil rigs and wind farms Benefits from energy infrastructure bottlenecks
EQT Vertically integrated natural gas producer and transporter in the Appalachian region Benefits from energy infrastructure bottlenecks
Freeport-McMoRan Global copper, gold, and molybdenum miner At the core of supply-demand imbalance

The article cites a 2022 study indicating that, driven by power infrastructure, renewable energy, transportation electrification, and AI investment, the world will need to mine more copper over the next 22 years than in the last 5,000 years combined. By 2030, AI data centers alone could add 1.5 million tons of copper demand, equivalent to 6% of current global production. However, the supply side is severely lacking: between 2019 and 2023, only four major copper discoveries were made globally, despite a combined exploration budget of over $12 billion. The article explicitly identifies uranium and rare earths as emerging research priorities, arguing that AI, geopolitics, and electrification are reshaping supply chains, and the supply constraints on these materials may create the most attractive investment opportunities.

Investment Implications

The core argument of the article is that global resource scarcity is intensifying, and the portfolio has expanded from long-held positions in Epiroc and Martin Marietta to include broader beneficiaries of energy and resource bottlenecks, such as Tidewater, EQT, and Freeport-McMoRan. The author explicitly identifies uranium and rare earths as the next research focus. It should be noted that this is a position-holder's perspective. The article uses the narrative of an "ancient complaint" and a "modern gold rush" to reinforce the logic of its investment thesis, and readers should be aware of the author's inherent bias toward self-justification.


Position Moves

Ticker Direction Author's One-Sentence View Key Data
Epiroc Hold & Watch Long-term hold, benefiting from mining automation and electrification trends Held since spin-off in 2018
Martin Marietta Materials Hold & Watch Aggregates "hyper-local monopoly" allows modest price increases Aggregate selling price $23/ton; transport cost exceeds rock cost beyond 30-40 miles
