Will copper unleash a new commodities 'supercycle'?

Some economists believe recently spiking copper prices are a harbinger of a new supercycle for commodities. The last one ended around 2014 amid faltering China growth. What’s fueling the current boom?

For much of the past two years, the global price of copper languished in the doldrums, barely fluctuating around the level of $8,500 (€7,890) for a ton, and being largely ignored by commodities traders. Since last month though, the metal is back in the focus of investors after surging to a fresh 2-year high of $10,110 at the London Metal Exchange (LME) on April 30.

"Index funds, exchange-traded funds, etc, are attracting retail money into metals. Momentum-based buying is pulling them up; selling resistance remains low," Sandeep Daga, a director at metals analysis company Metal Intelligence Centre, told news agency Reuters. He warned at the same time that the metal is "filled with the spirit of excitement, which is taking it far away from the reality."

The current reality, indeed, is that global growth is weakening, meaning copper prices should actually be coming under pressure because of falling demand — a correlation that's been valid throughout history. So why does it seem to be different this time around? And why are some experts even speaking of the beginning of a new commodities supercycle, led by copper?

A commodities supercycle is an extended period of rising prices for commodities across various sectors, driven by sustained demand growth, supply constraints, and broader economic factors.

The last commodities supercycle — affecting iron ore, agricultural products and minerals — began around the early 2000s and lasted until around 2014/2015. It was fueled by rapid industrialization and urbanization in emerging economies such as China.

Copper — the base metal of electrification

At the moment, the fresh enthusiasm of investors for copper is caused by its key role in global efforts to move away from fossil fuels towards energy systems based on renewables.

Joachim Berlebach, the founder and CEO of Earth Resource Investments in Zurich, says the metal is indispensable for electrification "due to its physical properties, especially its electrical conductivity."

"If we really want to move away from fossil fuels, we would need approximately the same amount of copper in the next three decades as in the entire previous history of mankind," he told DW.

Michael Widmer, a commodity strategist at the Bank of America (BofA), also thinks global decarbonization efforts are currently driving the price rally of copper. "Copper is used in almost every industry and is, therefore, considered an economic indicator," he told German business daily Handelsblatt recently.

Supply shortage caused by exploration slump

Both Berlebach and Widmer agree that the recent surge in copper prices is primarily the result of rising demand amid stagnating or even decreasing supplies since the end of the last supercycle. "Due to the lack of investments in new mines … there are not enough copper mines," said Berlebach.

Widmer calculated that investment in new mines would have to reach "at least $127 billion per year" in order to keep up with annual copper demand until 2050, as estimated by the International Energy Agency (IEA). "But last year, it was only $104 billion," he added.

The BofA expert sees no quick solution to lagging copper supply as building new mines "often encounters resistance," due to their environmental burden.  In the interview for Handelsblatt, he cited the recent closure of Panama's largest copper mine, which is run by the Canadian mining company First Quantum. "Initially, there was only a conflict between the government and First Quantum, then protests erupted among the local population. Ultimately, the government closed the mine and said it would not come back onto the market."

People wave flags after Panama's top court ruled unconstitutional a mining contract with Canadian miner First Quantum to operate a copper mine in the country, following weeks of protests against the deal, in Panama City.

Berlebach also said copper production cannot be ramped up quickly "because it takes up to 15 years from the first drill hole to production." He added that often "falling ore grades [mean] new mines also have to be designed larger."

Costly copper is here to stay

The days of copper production in Germany are long gone, although deposits still exist in some regions where the metal was mined several centuries ago.

Berlebach thinks domestic exploration and extraction is "relatively unproductive, and only theoretically possible." Operating large-scale mines in Germany, in general, would involve "lengthy bureaucratic processes," which is why the country will continue to depend on "deposits in South America and Congo."

He also does not consider metals such as aluminium as an alternative, as this can neither be used for landlines nor for coils in wind turbines or electric cars. "Aluminum has only about 65% of the conductivity of copper — the cables would be too thick."

Therefore, BofA analyst Widmer believes copper prices will remain elevated: "Of course, there may be short-term corrections, but in the long term, I see prices rising." He told Handelsblatt  that the metal may even experience "what is likely to be a long-lasting supercycle."

In the global hunt for copper, the Norwegian government now even wants to mine minerals from the seabed off its coast. Last year, it stated that there were "significant amounts of mineral resources" in Norwegian waters, including deposits of zinc, cobalt and copper.
