Glencore (GLEN) — The Diversified Commodity Cycle

Glencore plc (LSE: GLEN) is the world’s largest commodity trading company and one of the top five diversified miners, producing copper, cobalt, zinc, nickel, coal and oil. Its unique combination of mining assets and a global commodity trading division makes it unlike any other publicly listed mining company — and gives it earnings characteristics that do not fit neatly into any single commodity cycle signal. For investors who want broad commodity cycle exposure through a single stock, Glencore is the most comprehensive option available.

What Makes Glencore Unique

Glencore’s trading division — the Marketing segment — earns approximately $3–4bn of adjusted EBIT per year in a normalised environment, regardless of commodity prices. This is because the trading division profits from commodity price volatility and market dislocations rather than from price levels. When copper prices spike or coal markets dislocate (as they did in 2022), the trading division earns above its normalised rate. This creates a partial hedge: when commodity prices collapse (reducing mining earnings), volatility often increases (boosting trading earnings).

This trading buffer means Glencore is less sensitive to commodity troughs than pure miners — it has never reported a loss in any single year, even during the severe 2015–16 commodity downturn that nearly pushed it to the brink of financial distress. The debt restructuring and equity raise of 2015–16 was painful, but the company survived and subsequently delivered exceptional returns.

The Coal Question

Glencore is the world’s largest exporter of thermal coal, and this creates an ESG controversy that structurally depresses its valuation multiple versus copper-only peers. Many institutional investors — particularly those with ESG mandates — cannot hold Glencore due to its coal exposure. This exclusion reduces the buyer universe and keeps the P/E multiple below where it would be for a company with identical earnings but no coal.

Glencore’s counter-argument: it is better to own the coal assets and wind them down responsibly, extracting maximum value for shareholders while managing the decline, than to divest them to private owners who face no ESG pressure. The company has committed to reaching net-zero emissions by 2050 and has a managed coal decline strategy. Whether this is genuine or greenwashing is debated — but it has kept Glencore in more ESG-tolerant portfolios than a pure coal refusal would suggest.

Glencore’s Copper Growth Pipeline

Glencore’s most important long-term asset is Collahuasi in Chile (joint venture with Anglo American) — one of the world’s largest copper mines at altitude in the Atacama. Its Katanga and Mutanda operations in the DRC are critical cobalt producers — Glencore produces approximately 40% of global cobalt supply, making it the dominant force in battery supply chains for EVs. The combination of copper and cobalt from the same Congolese operations creates a dual battery-mineral exposure that is unique among large-cap miners.

Key Risks for Glencore Investors

DRC political risk: The Democratic Republic of Congo is one of the world’s most challenging operating environments. Glencore’s Katanga and Mutanda operations have faced operational suspensions, government disputes and security challenges. Any major disruption affects both copper and cobalt production simultaneously.

Coal regulation: Accelerating carbon taxes, import restrictions or coal phase-out mandates in key markets (EU, UK, Japan) could reduce coal demand faster than Glencore’s managed decline plan anticipates. A sudden coal demand collapse would hit earnings before asset sales could offset the impact.

Legal legacy: Glencore paid $1.5bn in corruption settlements in 2022 across the US, UK and Brazil for historical misconduct in Nigeria, the DRC and Venezuela. Regulatory monitoring and compliance costs are elevated, and reputational risk from any future violations is high.
