This is deliberately not a "commodities supercycle" bet. Broad commodity baskets blur together metals with completely different supply stories. Copper, lithium, and rare earths each face distinct, idiosyncratic scarcity dynamics that don't move in lockstep — and 2026 has already proven that point in real time. Part four of NGE's five-part series on structural investment themes for 2026.

Copper broke above $11,771 a tonne on December 8, 2025 — a record — and the rally has continued into 2026 on the back of a genuinely unusual cluster of supply-side disruptions rather than demand growth alone. The most acute shock came from Indonesia's Grasberg mine, the world's second-largest copper producer: a catastrophic mudslide in late 2025 severely damaged the Block Cave portion of the mine, which accounts for nearly 70% of its total output, with that section expected to remain closed until at least the second quarter of 2026 and full production not restored until 2027. Freeport-McMoRan slashed its 2026 output guidance by 35% as a direct result.
Grasberg was not an isolated incident. Disruptions also hit the Kamoa Kakula mine in the DRC, Chile's Quebrada Blanca and El Teniente operations, and several smaller producers across the same eighteen-month window — together removing close to 900,000 tonnes of supply from a market that was already running on multi-year-low stockpiles. Underneath the mine-site disruptions sits an even less visible constraint: smelting capacity. Treatment and refining charges — the fees miners pay smelters to process ore — plummeted to record lows through 2025, and Chinese smelters have implemented production caps to maintain profitability, creating what analysts call a "hidden bottleneck" where even available ore cannot be refined into usable cathode fast enough.
"The copper price 'explosion' of 2026 is the culmination of a decade of underinvestment in both discovery and processing." — Skillings Mining Review, May 2026
Lithium tells a near mirror-image story to copper. Prices collapsed more than 75% from their 2022 peak as Chinese producers ramped overcapacity well ahead of actual demand, flooding the market and crushing margins across the industry. That collapse forced real consequences — Pilbara Minerals, one of Australia's major lithium producers, placed its Ngungaju processing plant under care and maintenance in December 2024 as persistently weak spodumene (lithium ore) prices made continued operation uneconomical.
The more recent development is the part most investors have not fully priced: the lithium market is now projected to swing from surplus to deficit as Chinese producers finally rein in the overcapacity that caused the original price collapse, with prices beginning to partially recover through early 2026. This is the clearest illustration in this entire letter of why a blended commodity basket misleads — an investor holding broad commodity exposure through the worst of lithium's 75% drawdown captured none of the differentiated signal that this was a Chinese-overcapacity problem specific to one metal, not a demand-side collapse across industrial materials generally.
Rare earths remain structurally different from both copper and lithium because the constraint is not mining — it is processing concentration. China still controls the dominant share of global rare earth refining capacity, and crucially, that concentration has actually risen, not fallen, in recent years: the top three refining nations' combined share of processing capacity for major energy minerals climbed from approximately 82% in 2020 to 86% by 2024, with the vast majority of that growth concentrated specifically in China and Indonesia. China remains the dominant refiner across 19 of 20 strategic minerals identified by the IEA as critical to energy, defense, and artificial intelligence supply chains.
The practical consequence is stark: excluding China entirely from global supply calculations, the rest of the world is currently capable of meeting only around half of its own demand for battery metals and rare earths combined. This is the single most important data point in the entire commodity realignment thesis — every other metal's scarcity story is ultimately a price problem; rare earth concentration is a genuine access problem that price alone cannot solve on any reasonable timeline.
A Critical Minerals Ministerial convened in February 2026 brought together 54 countries specifically to coordinate a policy response to processing concentration — the scale of country participation alone signals how seriously this has become a coordinated geopolitical priority rather than a single-nation concern.
Roughly $14.8 billion in US EXIM Bank financing commitments tied to critical minerals projects were announced alongside the ministerial — real capital, though still small relative to the scale of processing infrastructure China has built over multiple decades.
Global investment in critical-mineral extraction and processing hit $128 billion in 2025, up 62% from 2023 — a genuinely sharp acceleration, though still a fraction of what would be required to meaningfully dent China's processing dominance within this decade.
US tariff threats and stockpiling behavior have already visibly distorted copper trade flows in 2025-26, with US inventories elevated relative to the rest of the world — a preview of how trade policy, not just mining investment, is becoming a direct tool in this realignment.
Copper's current record pricing is substantially a disruption story, and disruption stories have a tendency to resolve. Freeport has already stated full Grasberg production should return in 2027; if that timeline holds and no comparable new disruption emerges elsewhere, a meaningful share of the current price premium could compress relatively quickly. Goldman Sachs's more conservative $10,000–$11,000 forecast range for 2026, sitting well below JPMorgan's bullish case, reflects this exact uncertainty about durability rather than a fringe contrarian view.
The rare earth concentration problem is the most durable of the three, and also the hardest to express as a clean investment thesis. A processing-capacity gap that widened rather than narrowed over four years, despite billions in announced Western investment, suggests this is a multi-decade infrastructure-building challenge rather than a near-term tradeable catalyst. The $14.8 billion in EXIM financing and $128 billion in total 2025 sector investment are genuinely large numbers in isolation, but small relative to the scale of refining capacity China has built since recognizing this as a strategic priority decades ago.
The discipline this letter argues for is straightforward: resist the urge to buy "commodities are scarce" as a single thesis. Three metals at the center of the energy transition and the AI buildout are scarce for three completely different reasons, on three completely different timelines, with three completely different resolution paths. Copper's scarcity is a supply-disruption story with a stated recovery date. Lithium's is a Chinese-overcapacity story now inflecting. Rare earths' is a multi-decade processing-infrastructure story that policy is only beginning to address at meaningful scale. Conflating them into one trade loses exactly the information that makes each individually investable.
