How Rio-Glencore Reshapes Metal Sourcing Power

The global mining industry could face substantial transformation as Rio Tinto and Glencore resume merger discussions.

For supply chain professionals, this potential consolidation could fundamentally alter the procurement landscape for critical raw materials.

The renewed talks concern a potential combination that would create an entity with an enterprise value exceeding US$260bn. These discussions are taking place following conversations in early March 2025, when a previous attempt at a combination ended.

On Friday, both firms confirmed each was in "preliminary discussions" regarding a "possible combination of some or all of their businesses, which could include an all-share merger".

Rio Tinto, the FTSE 100 company founded in 1873, currently holds an enterprise value of US$162bn (£120bn).

In a formal statement, the company says: "The parties' current expectation is that any merger transaction would be effected through the acquisition of Glencore by Rio Tinto by way of a court-sanctioned scheme of arrangement. There can be no certainty that an offer will be made or as to the terms of any such offer, should one be made."

The development follows a period of deal-making in the natural resources sector, notably the US$53bn (£39bn) merger between BHP and Anglo American announced in September 2025.

Derren Nathan, Head of Equity Research at Hargreaves Lansdown, says: "Last year's theme of consolidation in the natural resources sector has shown no sign of let-up in the early part of 2026."

Supply chain implications for copper

A key driver for the potential merger is global demand for copper, a metal critical to supply chain operations across multiple sectors.

On 27 January 2026, prices for the metal reached more than US$13,300 (£9,900) a tonne, with projections from the International Copper Study Group indicating a potential supply shortfall of 10 million tonnes by 2040.

For supply chain managers, copper availability is required for power distribution and cooling systems in data centres supporting AI infrastructure. A merged Rio-Glencore entity would hold significant copper assets, potentially concentrating supplier power.

As Derren says: "A full combination would create a global leader in multiple industrial metals including iron ore and transition metals such as copper, cobalt and lithium."

Glencore's CEO, Gary Nagle, says the company's goal is to become "the biggest copper producer in the world". This consolidation could mean supply chain teams face fewer but larger suppliers for essential metals.

The concentration of copper supply in fewer hands raises questions about pricing power and supply security.

For procurement professionals managing long-term contracts, understanding how this merger might affect supplier relationships and negotiating positions will be critical to maintaining competitive advantage.

Fossil fuel strategy shift

One notable aspect of the 2026 talks is the potential shift in approach to fossil fuels, which could impact procurement strategies for companies managing diverse commodity portfolios. In 2024, the Financial Times reported that negotiations faced challenges partly due to disagreements over Glencore's coal operations; Rio Tinto exited the coal sector in 2018.

However, the political context has changed. Following Donald Trump's decision on 20 January 2025 to withdraw the US from key United Nations climate treaties and shifts in global energy policies, coal has remained profitable. The Financial Times reported that Rio may now be open to retaining Glencore's coal business, which could allow the company to maintain exposure to both transition metals and fossil fuel assets.

The merger would combine two companies with different operational profiles. Rio Tinto is a mining company with 60,000 employees, while Glencore – established in the 1970s by trader Marc Rich – has a workforce of 150,000 and operates in commodities trading. This trading capability could influence how materials reach end buyers.

This shift in strategy reflects broader changes in the commodities market, where companies are balancing transition metal portfolios with traditional fossil fuel assets. For supply chain professionals, this could mean greater flexibility in sourcing strategies but also increased complexity in managing supplier relationships across different commodity types.

Regulatory hurdles and market access

The deal faces regulatory scrutiny that could affect supply chain timelines and market access. Under UK takeover rules, Rio has until 5 February 2026 to make a formal offer. If it proceeds, it must navigate:

• China's regulators: As the largest consumer of iron ore and copper, Beijing's State Administration for Market Regulation (SAMR) may examine the merger's impact on pricing power
• The Australian Competition and Consumer Commission (ACCC) in Australia: Both firms operate in Western Australia and Queensland, where regulators may scrutinise control over ports, rail and market concentration
• EU review: Brussels may assess the combination's implications for access to critical raw materials for European manufacturing

As Gary argued in a statement accompanying the merger announcement, the industry needs to consolidate "not just for the sake of size, but also to create material synergies, to create relevance, to attract talent, to attract capital". For supply chain professionals managing material procurement, the regulatory response to these discussions could determine future supplier relationships and pricing structures.

The outcome of these regulatory reviews will have far-reaching implications for procurement teams worldwide. Any conditions imposed by regulators could affect contract terms, pricing mechanisms and supply guarantees that form the foundation of long-term sourcing strategies.
