Context
Copper prices hit a record $14,708 per tonne in September 2026, with London Metal Exchange (LME) futures above $14,000 for much of August. The surge is mainly linked to expected US tariffs on refined copper and pre-emptive stockpiling, rather than strong global demand.
Latest Developments
Copper prices crossed $12,000/tonne in December 2025, but fell to $11,929.5/tonne in March 2026 amid concerns over slower global growth following the West Asia conflict. Prices have since rebounded sharply amid expectations of US trade measures.
Why Copper Matters
- Infrastructure: Essential for power transmission, construction and manufacturing.
- Energy Transition: Important for renewable energy, energy storage and EVs.
- Digital Economy: Used in AI infrastructure and data centres for power and networking.
- Defence: Used in various defence and strategic applications.
- Economic Indicator: Known as “Dr Copper” because copper demand and prices are traditionally associated with economic activity.
Key Drivers of Copper Price Rise
- US Tariff Expectations: A proposed US tariff on refined copper—15% from January 2027 and 30% from 2028—has encouraged traders to buy and store copper in advance.
- Stockpiling: Copper is being moved to the US ahead of possible tariffs. Inventories are about 7 lakh tonnes at COMEX (US), compared with 2.65 lakh tonnes at LME and 63,000 tonnes at Shanghai Futures Exchange (SHFE), reducing availability outside the US.
- Arbitrage: The $400–500 per tonne LME–COMEX price gap has encouraged traders to shift copper between markets, though this remains a secondary factor.
- Supply Constraints: Limited mine output, including lower Chilean copper shipments, is adding to price pressure.
- Growing Demand: AI data centres, power grids, renewable energy, battery storage and EVs are increasing copper demand. EVs require significantly more copper than conventional vehicles.
Implications for India
- Higher Input Costs: Expensive copper can raise costs for power infrastructure, renewable energy and industrial production.
- Supply Pressure: Global competition for copper may increase India’s import dependence and exposure to supply disruptions and price volatility.
- Energy Transition: Copper availability and prices can affect the pace and cost of India’s infrastructure expansion and clean-energy transition.
Way Forward
- Supply Diversification: India should diversify sources of copper imports to reduce supply risks.
- Domestic Capacity: Strengthen domestic exploration, mining and copper-processing capacity.
- Recycling: Promote copper recycling and urban mining to reduce dependence on primary imports.
- Strategic Reserves: Assess the need for mechanisms to manage supply disruptions and extreme price volatility.
FAQs
Q1. What is the significance of COMEX copper inventories?
Ans. Large inventories at US COMEX warehouses indicate that copper has been redirected towards the US market. This has reduced readily available stocks on the LME and SHFE.
Q2. What is copper arbitrage?
Ans. Arbitrage involves purchasing copper in a lower-priced market and selling it in a higher-priced market.
Q3. Why is copper called “Dr Copper”?
Ans. Copper has extensive industrial applications, so its demand and price have traditionally been associated with the health of economic activity. Hence, it is often called “Dr Copper.”
Q4. What could cause copper prices to decline?
Ans. If US tariffs are delayed or set below market expectations, accumulated US inventories could flow back into global markets. This could increase supply and put downward pressure on prices.
