Copper and the long cycle

We do not trade commodities. But we watch the copper cycle closely, because it is one of the clearest teachers of the thing we care about most: what happens to durable assets when demand is certain and supply cannot keep up.

The metal electrification runs on

Almost every part of the energy transition is, underneath, a copper story. An electric vehicle uses roughly three to four times the copper of a combustion car. Grids, offshore wind and solar all need far more copper per unit of power than the infrastructure they replace. And now a new and largely unmodelled source of demand has arrived: the data centres behind artificial intelligence, which are enormous consumers of power and of the copper that distributes it.

Add these together and you get a demand curve that does not just grow, it steepens. Electrification is not one market. It is many markets turning copper intensive at the same time.

Supply moves in decades, not quarters

Copper supply cannot respond quickly, and this is the crux. From discovery to a producing mine is commonly ten to twenty years, through exploration, permitting, financing and construction. Large new discoveries are rare. The ore grades of existing mines are falling, which means moving more rock every year to produce the same amount of metal. The best jurisdictions are harder to permit, not easier.

So you have a demand curve bending upward and a supply curve that answers on a delay measured in decades. That is the classic setup for a structural deficit, the kind that is not solved by a single new mine or a single good year.

It is a cycle, not a line

None of this means the price only goes up. Commodities are cyclical for a reason. Recessions crush demand in the short run. High prices invite substitution, and aluminium caps how far copper can run before buyers switch where they can. Prices overshoot at the top and undershoot at the bottom, and the people who confidently call the turn are usually wrong about the timing.

The discipline the copper cycle rewards is not prediction. It is the ability to think in the cycle rather than the quarter, and to still be holding a good asset when the cycle turns.

Why a permanent owner pays attention

We find this instructive far beyond metals. The copper cycle rewards exactly the temperament we try to build the firm around: owning real, hard to replicate assets with durable demand, and having the staying power to hold them through the trough when others are forced sellers. Permanence is most valuable precisely at the bottom, when the people with a clock have to sell and the people without one can wait.

The investors who do well across a commodity cycle are rarely the ones who called the top. They are the ones who were still holding a good asset when it turned. That is not a trade. It is a philosophy, and it is the same one we apply to the businesses we buy.
