Macquarie Says Copper Is Oversupplied and Overpriced – by Frik Els (Mining.com – March 26, 2026)

Key Takeaways

• Copper price down 1.5% to $5.47 per pound.
• Fell 16% from January all‑time high.
• Macquarie attributes rally to speculative investor flows.
• Open interest dropped $24.6 bn in Feb‑Mar.
• Oversupply risk may pressure mining earnings.

Summary

Macquarie’s strategy team says copper is oversupplied and overpriced after a 1.5% drop to $5.47 per pound, roughly $12,000 a tonne. The metal has shed more than 16% – about $2,400 per tonne – from its January peak. The bank argues the recent rally was driven largely by speculative investor flows rather than supply‑demand fundamentals. Open interest surged $9.5 bn in December‑January before reversing, with a $24.6 bn decline through February and March.

Pulse Analysis

Macquarie’s latest research challenges the narrative that copper’s recent price surge reflects a tightening market. By highlighting a 16% retreat from its January high and a modest 1.5% dip on Thursday, the bank underscores that the metal’s valuation may be detached from underlying supply‑demand dynamics. The oversupply assessment aligns with broader commodity trends where inventory builds and new production capacity have outpaced demand growth, especially in emerging economies that are still scaling their electrification projects.

The report points to investor behavior as the primary catalyst behind the earlier rally. Futures‑exchange volumes in Shanghai jumped 80% in January, and aggregate open interest across New York, London, and Shanghai rose by $9.5 billion before a sharp $24.6 billion withdrawal in February‑March. Such capital flows suggest that speculative positioning, rather than fundamental scarcity, fueled price gains. This pattern mirrors other base‑metal markets where hedge funds and index funds amplify price movements, creating volatility that can mislead traditional market participants.

For miners, downstream users, and investors, Macquarie’s warning signals a need to reassess exposure. Producers may face tighter margins if prices continue to drift lower, prompting cost‑cutting measures or delayed capital projects. Conversely, investors might seek hedging strategies or diversify into metals with stronger demand fundamentals. Monitoring inventory data, production forecasts, and macro‑economic indicators will be crucial as the market recalibrates from speculative excess toward a more sustainable pricing trajectory.
