Glencore’s copper expansion plans face pressure from a sector sell-off and operational hurdles, as the miner pursues a $1B cost-cut plan and portfolio restructuring.

A sudden bear market in copper is creating significant headwinds for Glencore’s ambitious growth plans. The mining giant’s strategic pivot toward the red industrial metal now faces a stern test as global commodity markets experience a widespread sell-off, challenging the company’s long-term trajectory.

Market Turbulence Disrupts Momentum

Global commodity markets came under substantial pressure last Friday. Geopolitical tensions and weakening worldwide demand triggered a sector-wide sell-off, officially pushing copper into bear market territory. For Glencore’s equity, this translated into a setback: shares closed the session at €5.96, retreating slightly from the 52-week high of €6.13 marked in early March. Despite this recent dip, the stock still maintains a remarkably strong year-to-date performance, showing a gain of over 59 percent.

This price slump arrives at a sensitive juncture for the company. Management recently outlined a target to ramp up annual copper production to 1.6 million tonnes by 2035. The strategy to achieve this hinges primarily on expanding existing mines and restarting idled operations, such as the planned reopening of the Alumbrera mine in Argentina in 2028.

However, the recent downward revision of copper prices complicates the near-term assessment of these extensive expansion plans. This comes after Glencore had already slightly lowered its 2026 production forecasts due to operational challenges and lower ore grades at its Collahuasi mine in Chile.

Strategic Restructuring Amid Operational Challenges

Concurrently with its copper push, Glencore’s management is advancing a comprehensive portfolio restructuring. The company plans to divest a 70% stake in Kazzinc, a Kazakh zinc and lead producer. Negotiations are also ongoing to sell a 40% interest in its copper and cobalt business in the Democratic Republic of Congo to the US-led Orion consortium.

Should investors sell immediately? Or is it worth buying Glencore?

Further complications are emerging in South Africa. Talks with state-owned power utility Eskom regarding competitive electricity tariffs for Glencore’s highly energy-intensive ferrochrome production have stalled. An agreement was initially expected by the end of February. The profitability of these assets is now significantly threatened without a reliable, cost-effective power supply.

Following the collapse of its proposed merger with Rio Tinto in February, Glencore must now drive growth independently. A central factor for success in the coming months is an ongoing efficiency program designed to reduce operational costs by approximately $1 billion.

If these cost savings are realized and the copper market stabilizes, the long-term demand drivers—namely the global expansion of electric mobility and new AI data centers—provide the fundamental backdrop needed to support Glencore’s targeted production increases. The company’s ability to navigate the current price volatility while executing its complex strategic overhaul will be critical in the months ahead.
