Mining supercycle: Big money bets billions

Major fund managers have predicted a sustained rally for mining and metals, as money pours in at the fastest rate in years. This is due to a robust AI infrastructure, increased defence spending, and a move away from expensive technology stocks.

The assets under management of mining exchange-traded funds grew by more than twofold to $87.4 Billion by March 31 compared with $37 Billion a year ago, according to data compiled for ETFGI by the research firm. shows.

Oil and gas?and agriculture also saw significant inflows. This marks one of the sharpest shifts in investment towards hard assets ever.

Investors invested $8.24 billion in mining in the first 3 months of 2019. This is a change of $10.8 billion in sentiment from the first three month of 2025, when President Donald Trump announced sweeping tariffs that resulted in a $2.52 billion outflow.

BlackRock portfolio manager Evy Hambro said capital was starting to move from high-valued tech stocks into hard assets. She called it "the beginning stages of a commodities supercycle".

Morningstar's U.S. Technology Index dropped 9% in the 1st quarter. BHP and Rio Tinto, the two world's largest mining companies, have both seen their shares reach record highs in this year.

Hambro stated that "the material intensity of GDP?is increasing", pointing out the surge in capital investments into grid infrastructure, data centers, electric vehicles, and charging stations.

Hambro, a leading analyst, said that unlike the urbanisation-driven boom of China in 2000, demand in this cycle is "much stronger and more resilient", because there's global diversification in AI, electrification, and defence.

Analysts and investors said that the change in market structure increases the risk of price fluctuations, as metals are smaller than global equity and bond markets and more susceptible to bottlenecks within mining, refining, and transportation.

Taosha Wan, from Fidelity, also stated that a supercycle focused on mining and energy has already begun as the Iran War pushes government to prioritize supply security.

GOLD VS INDUSTRIAL METAL

The flow of funds has been skewed towards industrial metals. In March, copper funds received $198 million while gold's raging rally was accompanied by profit-taking. VanEck Gold Miners ETF (GDX) alone lost $710 millions last month but is still up over $1 billion for the year. Investors say that the pullback of gold in a geopolitical crisis is notable. Investors say that rather than seek shelter in safe havens, the markets are betting on the Iran conflict to catalyse real-economy responses, requiring energy security and infrastructure investments requiring steel, copper, and rare Earths.

Fund managers say that the fact that oil and gas funds have received almost $6 billion net in the first three months of the year confirms the idea investors are preparing for infrastructure spending.

Portfolio managers are attracted to diversified miners such as BHP and Rio Tinto, which sit at the intersection of many demand drivers.

Anix Vyas is a portfolio manager for Harding Loevner. He said that aluminum and copper are in high demand. This demand has increased as the Iran Crisis unfolds. Rio Tinto, which holds both metals, can also benefit from an increase in demand due to data centres?and industrial applications.

Vyas described the shift as investors leaving software companies that are vulnerable to AI disruption in favor of companies with more durable advantages like miners who control critical minerals.

Small Markets, Big Swings

Metals futures are relatively small, so heavy inflows may magnify volatility while a larger uptrend is still intact.

The London Metal Exchange reported that trading volumes in metals futures, including copper and aluminum, totaled $21 trillion. Meanwhile, the CME recorded gold futures trades of more than $25 trillion. This pales in comparison to the $85 trillion generated by Nasdaq 100?futures, and the more than $135 billion in S&P500 futures.

The dramatic swings in ETF flows from one year to the next show how easily sentiment can change and how susceptible these markets are for a reversal.

This sector also represents a very small portion of the global market. The top?five mining firms represent just 0.4% of MSCI ACWI Index, compared to 16.8% of the top five technology companies. Metals and mining products make up just 0.57% of the total equity ETF share.

The major mining companies' shares are still trading at 7 to 8 EV/EBITDA multiples, which is well below the 14-times multiples seen in the 2008-2010 boom. This suggests that there could be significant upside potential if the supercycle continues.

Copper is at the intersection between everything and critically undersupplied. "I have no doubt that copper prices could double or even triple in the next decade, and owning producers of copper will provide multiples of the spot price increase," said Charlie Aitken. He is the group investment director for Australia's Regal Partners. The company is overweight with mining and metals, and had A$21 billion (15.05 billion) at its disposal at the end March.

Investors said that while investing in this sector offers an inflation hedge, it could also lead to price increases, which would compound inflation pressures caused by the Iran War's impact on the energy markets, and pose risks to the global economy.
