Copper Prices Surge as Major Mine Disruption Creates Supply Shortage
Copper prices have reached their highest levels in over a year due to a major supply disruption at Freeport-McMoRan's Grasberg mine in Indonesia, the world's second-largest copper mine. The company has declared force majeure on contracted supplies and reduced its copper and gold sales guidance following an accident that led to a temporary halt in operations. The incident has resulted in a 3.90% surge in copper futures, with prices on the London Metal Exchange trading at $10,310.00 per tonne. Analysts have adjusted production outlooks and price forecasts, with Goldman Sachs projecting potential increases to $10,200.00-$10,500.00 per ton by December 2025.

Copper prices are holding steady near their highest levels in over a year following a significant supply disruption at one of the world's largest copper mines. The market reacted strongly to news of Freeport-McMoRan declaring force majeure on contracted supplies from its Indonesian operation.
Supply Disruption at Freeport's Indonesia Mine
Freeport-McMoRan, a major player in the global copper market, has reduced its copper and gold sales guidance for the quarter due to an accident at its Indonesian mine. The company is currently searching for five missing workers following the incident, which has led to a temporary halt in operations at the Grasberg mine, the world's second-largest copper mine.
Market Response
The copper market demonstrated its sensitivity to supply disruptions as futures surged 3.90% on Wednesday in response to the news. However, prices have since edged slightly lower, with copper on the London Metal Exchange trading down 0.30% to $10,310.00 per tonne.
Production Outlook and Price Forecasts
BMO Capital Markets reported a preliminary 35% cut to the 2026 production outlook for the Grasberg mine, with output not expected to return to pre-incident levels until 2027. Goldman Sachs has reduced global copper mine supply estimates for 2025 and 2026, expecting production declines of 250,000-260,000 tons in 2025 and 270,000 tons in 2026.
Goldman Sachs highlighted upside risks to its December 2025 copper price forecast of $9,700.00 per ton, with potential increases to $10,200.00-$10,500.00, and projects copper reaching $10,750.00 per ton by 2027. Motilal Oswal forecasts copper prices could reach $11,700.00 on LME and Rs. 1,080.00 on MCX from a medium to long-term perspective.
Demand Drivers
China accounts for roughly 60% of global copper demand, driven by a $300 billion grid modernization initiative and renewable energy expansion. Electric vehicle demand is expected to increase copper consumption from 1.2 million tons in 2025 to 2.2 million tons by 2030, as EVs require 25-50 kg of copper compared to 8-12 kg in traditional vehicles.
Investment Trends
Copper-focused ETFs have attracted $2.3 billion in net inflows in 2025, representing a 45% increase over 2024, indicating growing investor interest in the metal.
Broader Industry Challenges
This incident highlights the vulnerability of the copper market to supply disruptions. It adds to recent challenges faced by the industry, including:
- Hudbay Minerals shutting down its Peru operations due to political protests
- Ongoing concerns about global copper supply meeting increasing demand
Market Implications
The current situation underscores the delicate balance in the copper market between supply and demand. As the world continues to push for electrification and renewable energy solutions, copper remains a critical material. Any significant disruption in supply, such as the one at Freeport-McMoRan's Indonesia mine, can have substantial impacts on global prices and availability.
Industry analysts will be closely monitoring the situation at the Indonesian mine, as well as other potential supply constraints, to gauge their effects on the copper market in the coming weeks and months.
