Copper
Copper is what the grid is made of, which is why its price behaves like a bet on construction, electrification and Chinese industry all at once.
At a glance
- Traded as
- Refined cathode, 99.99% pure

- USD per tonne (LME) or USD per pound (COMEX)
- World mine production
- About 23 million tonnes in 2024
- Largest producer
- Chile, roughly a quarter of mine supply
What is actually being traded
Copper moves through the world in three forms, and confusing them is the first mistake. Mines produce concentrate, a powder that is only about a quarter to a third copper by weight. Smelters and refineries turn that into cathode, sheets of metal at 99.99% purity. And roughly a third of the copper used each year never came out of a mine at all: it is scrap, melted and used again.
When a market talks about the copper price, it means refined cathode. That is what the exchanges list, what the benchmark contracts deliver, and what a fabricator turns into wire rod and tube.
The second trap is the unit. London quotes copper in US dollars per tonne, New York in US dollars per pound, and one tonne is about 2,205 pounds. A headline saying copper hit five dollars and one saying it hit eleven thousand can describe the same day.
USD 5 per pound and USD 11,000 per tonne are roughly the same price. Always check which exchange a claim is quoting.
What it is used for
Copper conducts electricity better than any affordable metal, and that single property explains almost all of its demand. It is in building wiring, motors, transformers, grid cables, data centre busbars and every electric vehicle — which uses several times more copper than a combustion car.
That makes copper demand a proxy for two things at once: how much is being built, and how fast electricity is replacing fuel. Those two can pull in opposite directions, which is why a weak construction cycle and a strong electrification story can leave the price going nowhere for a year.

Where it comes from
Copper mining is unusually concentrated. Chile alone produced roughly 5.3 million tonnes in 2024, about a quarter of world mine supply, and the Democratic Republic of the Congo has overtaken Peru for second place on the back of a decade of Chinese-financed expansion.
Reserves are concentrated in the same places, so this map changes slowly. What changes quickly is grade: the average ore body being mined today contains less copper than it did twenty years ago, which means more rock, more water and more power for the same tonne of metal. That is a structural cost floor, not a cycle.

Behind the subscription
The rest of this entry is the part that changes a decision: what moves the price, which contract sets it, who ships it and where that can be cut off.
What moves the price
The eight forces that actually set the copper price, sorted by which way each one pushes and how hard — from Chinese grid spending to treatment charges and scrap.
Where it is traded
The three exchanges that price copper, their contract sizes, tickers and settlement - and why the same metal can trade at two different prices in London and New York.
Who ships it, and where it can be cut off
Who exports copper, who buys it, and the three points - two ports and one industry - where the flow is thin enough that a single disruption reprices the metal.
How this shows up in prediction markets
What a copper question is really asking, which number settles it, and the checks to run before you price one.

Frequently asked questions
- Why is copper called an economic barometer?
- Because it goes into almost everything that gets built or wired, and more than half of demand lands in China. That makes it a live read on industrial activity - though it now carries an electrification story that can pull it away from the construction cycle.
- Why do London and New York show different copper prices?
- Different units and, at times, genuinely different markets. LME quotes dollars per tonne, COMEX dollars per pound. When US import tariffs are in play, COMEX can hold a persistent premium until enough metal physically relocates to close it.
- Who produces the most copper?
- Chile, at roughly a quarter of world mine production in 2024, followed by the Democratic Republic of the Congo and Peru. Refining is a different map: China refines about half the world's copper regardless of where it was mined.
- What is the fastest thing that moves the copper price?
- Supply disruption at a large mine, because those tonnes cannot be replaced quickly. On the other side, scrap is the fastest supply response - high prices pull it out of storage within weeks and cap rallies.
