While oil and gold hog the headlines, the metals that actually power the energy transition are quietly setting up 2026's most divergent commodity story: copper is tightening, lithium demand is booming while its price stays crushed, and governments on both sides of the Atlantic are spending billions to secure supply chains they no longer trust.
Copper: the tightness trade
Copper enters the second half with the most conventional bull case of the group: demand keeps rising, supply keeps disappointing, and global inventories have been drawn down. Analysts broadly expect the market to stay tight through 2026. Unlike the battery metals, copper never had a speculative price collapse to digest — its constraint is structural, in mine supply that takes a decade to bring online. For traders, that makes copper the cleanest proxy for the electrification theme, and also the metal most sensitive to any growth scare: tight markets cut both ways.
Lithium: booming volume, broken price
Lithium is the strange one. J.P. Morgan research expects global lithium demand to grow around 16% year-over-year in 2026 — with 58% of the incremental demand coming from electric vehicles and another 30% from energy storage systems. Yet the price has collapsed more than 80% since 2023, unwinding the eightfold spike of 2021-22, and other battery inputs (graphite, cobalt, nickel) have also drifted back toward pre-pandemic levels. The lesson is one every commodity trader eventually learns: demand growth is not a price forecast — supply overshoots matter just as much. The open question for 2026 is whether relentless volume growth finally eats through the surplus, and whether the marginal producers that survived the bear market can meet it when it does.
The new cost risk nobody watches: sulphuric acid
A less obvious wrinkle: more than half of the lithium, cobalt, rare-earth and purified phosphoric acid production expected in 2026 is exposed to disruptions in sulphur and sulphuric acid supply — a processing input most investors never think about. If that bottleneck bites, it raises production costs across the whole critical-minerals complex at once, which is the kind of correlated cost shock that can put a floor under prices even in oversupplied markets.
Governments are now market participants
The strategic layer keeps thickening. The EU plans roughly EUR 3 billion in spending this year to loosen China's grip on critical-mineral supplies, including a new body to oversee investments and build physical stockpiles for energy, aerospace and defense needs. Washington keeps its own critical-minerals push running through policy and procurement. And the private sector is following the money: global mining M&A hit about $21.6 billion in the first quarter — the strongest Q1 since 2023 — as majors buy the supply they cannot build fast enough.
The trader's takeaway
Three different setups, one theme:
Strategic buying — whether by central banks in gold or by governments in minerals — is price-insensitive, and price-insensitive buyers change how markets behave. This corner of the commodity complex is no longer just about supply and demand; it is about security of supply, and that premium tends to grow.

The trader's takeaway
Three different setups, one theme:
- Copper — a tightness story; watch inventories and Chinese demand data.
- Lithium — a bottoming story; watch supply curtailments, not demand headlines.
- Rare earths and the rest — a policy story; stockpiling programs and export controls can reprice small markets overnight.
