Copper: India's New Oil, and HCL Is Digging In

How does Hindustan Copper make money?

Hindustan Copper digs copper ore out of the ground, processes it, and sells the refined metal to companies that make wires, pipes, and electronics. It is India's only vertically integrated copper producer, meaning it handles everything from mining to sale. Its growth loop: more mining brings more ore, which brings more copper to sell, which funds more mining.

Why would India's state-owned oil and coal giants want to dig for copper?

They are chasing the same demand that is lifting copper prices. Oil India, Coal India, NTPC Mining, GAIL and others have signed MoUs with Hindustan Copper to jointly bid for copper and critical mineral blocks, aiming to secure supplies for India's clean energy transition, EVs and grid storage. Copper is essential to all of them, so energy PSUs are diversifying into mining it.

What would break the bull case for copper prices?

A supply surplus. Investment bank Goldman Sachs sees a 500,000-tonne surplus in 2025 and a smaller 160,000-tonne surplus in 2026, meaning no shortage soon. Futures prices for December 2027 are below the spot price, signalling markets expect a decline. Our read: if surplus persists, copper prices soften and Hindustan Copper's expansion math weakens.

What did Hindustan Copper actually deliver?

Hindustan Copper delivered record financials, not just plans. For FY26, profit before tax hit Rs 1,232.73 crore, up 95% from Rs 633.51 crore a year earlier, with profit after tax rising 97% to Rs 920.67 crore. Ore production grew 6% to 3.67 million tonnes, and cathode sales rose 12% to 27,369 tonnes. The Rs 7,000 crore investment and MoUs are intentions for the next 5-6 years, not current output.

Copper is essential to all of them, so energy PSUs are diversifying into mining it.

What happens if the tariff hits even without a future shortage?

A US tariff on refined copper imports, likely at least 25% per Goldman Sachs Research, would pull metal into US warehouses as importers stock up before the tax lands, steadying flows next year. Prices would dip after implementation, then resume climbing. The real effect is geographic: supplies tighten outside the US, which supports the price HCL's expansion math depends on, even before any demand-driven shortage arrives. Our read: the tariff is a near-term price prop, not the 2035 bull case.

Why is the world's top copper miner helping India's smallest one?

The MoU is a capacity-building and knowledge-sharing arrangement, not an ownership stake. Chile's Codelco produced 1,307 kt of its own copper in 2025 versus HCL's roughly 27,000 tonnes of cathode sales, making the Indian miner a minor player by comparison. For Codelco, the deal opens access to India's fast-growing demand at no cost to its own output. Our read: the partnership is Codelco's low-risk way to plant a flag in an import-dependent market it expects to grow.

What does Codelco get out of teaching a much smaller miner?

Codelco's own production actually fell 1.6% in 2025 to 1,307 kt, with cash costs up to 211.7 cents per pound, so it has no spare copper to sell India. The MoU costs it almost nothing while opening a door to a market driving a large share of future demand growth. The bigger prize may be influence in India's mineral auctions, where HCL is the designated bidder. Our read: Codelco is buying a seat at India's table, not selling copper.

Why is Codelco's copper output actually falling?

Production fell 1.6% in 2025 to 1,307 kt, with Chuquicamata down 15.1% and El Teniente down 13.0% after a July 31 fatal incident. Codelco prioritised higher-grade ore at Radomiro Tomic at Chuquicamata's expense, and cash costs rose to 211.7 cents per pound as lower output absorbed fewer fixed costs. Its 2026 guidance of 1,331-1,357 kt implies only a modest recovery. Our read: falling output, not spare capacity, is why the MoU with HCL costs Codelco nothing to sign.

Does Codelco's turnaround plan depend on copper staying expensive?

Codelco's own 2025 profit before tax jumped to US$4.9 billion from US$790 million, but that was driven mostly by a 12.2% rise in realised copper prices to 463.0 cents per pound, not by producing more. Output actually fell 1.6%, and cash costs rose to 211.7 cents per pound. Its 2026 guidance targets only a modest production recovery, while capital spending stays heavy. Our read: Codelco's finances currently ride the copper price, not its own expansion, so a price slump would squeeze it fast.

What would a price slump do to Codelco's turnaround plan?

Codelco's 2026 guidance targets own production of 1,331-1,357 kt, a modest recovery from 1,307 kt in 2025, with cash costs expected to rise to 225-221 cents per pound and capital spending staying heavy at $4.0-5.0 billion. Its 2025 profit jump to $4.9 billion came largely from realised prices up 12.2%, not output growth. If LME copper falls toward the World Bank's 2026 forecast of $9,800 per tonne, Codelco's margins would compress sharply against rising costs. Our read: Codelco's recovery plan assumes high prices, so a slump would force it to delay expansion and lean on its lithium partnership for cash.

What would break the bull case for copper prices?

A supply surplus. Goldman Sachs sees a 500,000-tonne surplus in 2025 and a smaller 160,000-tonne surplus in 2026, meaning no shortage soon.
