BloombergNEF Lifts the Shortage Alert on Nine Metals, Not on Copper

For transition metals, the thesis is no longer a basket trade. In our view, it is a metal-by-metal choice. On 20 October, BloombergNEF published its Transition Metals Outlook 2026. The verdict: nine of the ten materials studied have sufficient supply through 2050, against three projected deficits last year 1. One major exception remains: copper. The study covers aluminium, cobalt, copper, graphite, lithium, manganese, nickel, platinum, palladium and steel 1. It does not cover uranium, rare earths or tin. Within that scope, the message is clear: scarcity no longer spreads, it concentrates.

Copper, the only structural deficit

BNEF puts the additional mine investment needed to avoid a copper shortage at $332 billion 1. Demand rises 61% between 2026 and 2050, to almost 46 million tonnes 1. The deficit opens as early as 2028 and reaches 20 million tonnes by 2050, or 44% of projected demand 1.

On the mining side, the strain is building. The International Copper Study Group cut its 2026 mine-production growth forecast to 1.3%, from 1.6%, after revisions in Chile, China and Indonesia 2. BHP expects a structural deficit from 2028, while acknowledging it is not there yet 2.

The counter-argument: the end of the scarcity premium

The objection is serious. In the near term, refined metal remains in surplus: the ICSG forecasts a surplus of 104,000 tonnes in 2026 and 368,000 tonnes in 2027 3. And if shortages recede in lithium, graphite or nickel, the complex loses its scarcity premium. BNEF indeed expects lasting downward pressure on nickel and cobalt prices, and an easing of the lithium deficit as new capacity arrives in 2027 1.

That, in our view, is precisely the case for selectivity. An equal-weighted "energy transition" basket buys metals in surplus. A concentrated exposure to documented deficits buys scarcity. The same report that reassures on nine metals confirms the investment gap in copper, the first input of electrification.

The bottom line

We think copper producers, from the mine in development to the emerging producer, capture most of the structural tension. Nickel and cobalt exposures demand more discipline on production costs.

What to watch: final investment decisions on large copper projects, the ICSG's 2027 mine-growth forecast (expected at 3.1% 2), and the gap between announced capacity and capacity actually brought into production.
