# Copper: Cycles

The 2026 surge to a record monthly price

Source page: https://www.materialinsights.org/commodities/copper/cycles/

What this tab covers Price history and what drives booms and busts, including this commodity's super-cycles, the drivers behind them and the metrics to track. It charts monthly prices (World Bank) with a switch to inflation-adjusted annual prices; where there is no World Bank series it uses USGS US prices.

Copper reached $14,474 a tonne in September 2026, its highest monthly price since at least 2000. That is 45% above a year earlier and 55% above five years earlier; the ten-year low was $4,472. In real 2010 dollars the 2025 average of $8,568 already beat the 2011 boom year, $7,950. Booms come when demand surges, as with China's build-out in the 2000s, and new mines take many years to deliver. Busts follow when projects arrive together. When producers reopened the taps in 1983, exchange stocks swelled from 300,000 tonnes in early 1982 to over 800,000 by late 1983, and prices took nearly four years to recover (Humphreys).

#### Super-cycles in copper

Copper has had clear super-cycles: long upswings driven by industrialisation that outlast normal business cycles, because new mines take many years to build. In nominal terms the World Bank monthly price rose from about $1,100/t in the early 1970s to a record $14,474/t in September 2026. In real terms the picture is flatter: the 2025 average of $8,568/t in 2010 dollars was only modestly above the 2011 boom year ($7,950). Busts come when capacity built in a boom arrives together and demand slows, as in 1975, 1982-86, 1998-2002 and 2015-16.

1. 1973-1975

A synchronised world boom, the oil shock and stockpiling pushed prices up, then recession knocked them down. CIPEC, the exporters' council, tried production cuts in 1974-76 but its members held only 37% of mine supply in 1975 and failed (Radetzki and Wårell 2021).

World Bank monthly price rose from $1,119/t (Jan 1973) to $3,032/t (Apr 1974), then fell to $1,151/t (Dec 1975)

2. 1982-1989

After producers restarted idle capacity in 1983, exchange stocks swelled from about 300 kt to over 800 kt (Humphreys 2015) and prices stayed low until 1987. Strong demand and falling stocks then drove a sharp squeeze.

From $1,273/t (Oct 1984) to $3,499/t (Dec 1988) (World Bank monthly averages)

3. 2003-2011

China's urbanisation and grid build-out lifted demand faster than mines could respond. Treatment and refining charges fell from an average 23% of the copper price (1980-2005) to about 5% in 2007 as smelters competed for concentrate (Humphreys 2015). The 2008 crisis caused a brief crash before Chinese stimulus revived prices.

From $1,587/t (Apr 2003) to $8,685/t (Apr 2008), down to $3,072/t (Dec 2008), then a peak of $9,868/t (Feb 2011) (World Bank monthly averages)

4. 2011-2016

New mines from the boom came on stream as Chinese growth slowed, and the market moved into surplus.

Fell to $4,472/t (Jan 2016), the ten-year low (World Bank monthly averages)

5. 2020-2026

Post-Covid stimulus, energy-transition demand, mine disruptions and, in 2025, US tariff fears that pulled metal into US stocks. US refined stocks rose from 123 kt to 450 kt in 2025 (USGS).

From $5,058/t (Apr 2020) to $10,162/t (May 2021), then a record $14,474/t (Sep 2026) (World Bank monthly averages)

#### What drives the cycle

- **China construction, grid and manufacturing.** China refines about 48% of the world's copper (USGS 2025) and is the largest consumer, so its property and grid cycles set the tone for demand.
- **Electrification and energy transition.** Grids, renewables, EVs and data centres are copper intensive, adding demand on top of traditional construction and equipment uses.
- **Mine supply lags and falling ore grades.** Large new mines take many years from discovery to output. Grades are falling in Chile and the US, so more ore must be moved for each tonne of copper.
- **Resource nationalism and disruptions.** Strikes, permits, royalties and accidents in Chile, Peru, Panama, Indonesia and the DRC regularly remove supply at short notice.
- **Trade policy and stocks.** US tariffs in 2025 opened a COMEX premium over the LME and moved large stocks into the US, tightening metal available elsewhere.

#### Metrics to track

| Metric | Why it matters | Where to track it |
|---|---|---|
| **LME, COMEX and SHFE exchange stocks** | Low or falling visible stocks signal tightness and often precede price spikes | LME daily stock reports; CME Group; Shanghai Futures Exchange weekly |
| **Spot and benchmark treatment and refining charges (TC/RCs)** | Low TCs mean smelters are short of concentrate, an early sign of mine supply stress | Fastmarkets, SMM, Mysteel spot assessments; annual benchmark settlements reported by Reuters |
| **ICSG refined balance and mine output** | Monthly world surplus or deficit estimates | International Copper Study Group monthly bulletin and press releases |
| **China grid investment and property starts** | Leading indicators for cable and building wire demand | China National Energy Administration and National Bureau of Statistics monthly releases |
| **Yangshan cathode premium** | Measures China's appetite for imported refined copper | SMM and Fastmarkets assessments |
| **COMEX minus LME spread** | Shows US tariff effects and pull of metal into the US | CME Group and LME prices, tracked by Reuters columnists |
| **India refined copper demand and imports** | Fast-growing market and a test of new smelter capacity | Hindalco and Hindustan Copper results; DGCIS trade data; Ministry of Mines monthly summary |
