Copper prices jumped nearly 5% after the operator of Indonesia’s Grasberg mine announced a force majeure due to an accident. This has raised concerns about supply shortages, as treatment and refining charges at copper smelters have fallen, indicating a lack of raw materials. The International Copper Study Group noted that mine production increased in the first seven months of the year, with gains from Chile, Peru, and the Democratic Republic of Congo. However, output from Indonesia dropped by 32% due to ongoing problems at the Grasberg mine. Overall, global mine production rose by 3.4%, and metal production went up by 3.9% compared to last year. Even though global demand is rising, particularly from China—which consumes about 60% of copper—there’s still a supply surplus of 100,000 tons. This is down from a 400,000 ton surplus last year, showing the market is still well-supplied, but less so than before. Experts predict production may not grow as much as in previous years, but it should remain at a high level. The recent 5% jump in copper prices highlights how sensitive the market is to supply news, like the disruption at Indonesia’s Grasberg mine. This event pushed London Metal Exchange (LME) copper prices to around $9,200 per metric ton, signaling market worry about potential shortages. This suggests that upcoming headline risks could drive market volatility. This anxiety is heightened by the tumble in treatment and refining charges, which have plummeted to under $5 per ton from over $80 per ton in 2024. Such low charges indicate fierce competition for raw copper concentrate, supporting the narrative of a supply shortage. This powerful market signal creates a bullish sentiment even when broader data says otherwise. Despite these concerns, global mine production actually grew by 3.4% in the first seven months of this year. Increases from major producers like Chile and the Democratic Republic of Congo outweighed the 32% production decrease from Indonesia. The resilience in supply indicates that the fundamentals are not as tight as recent price movements suggest. On the demand side, China remains the main driver, accounting for about 60% of global consumption. This demand is primarily fueled by the country’s green energy transition, with electric vehicle sales rising 25% year-over-year through August 2025. However, this strong demand hasn’t fully absorbed the increase in production. Data shows that the global copper market had a supply surplus of 100,000 tons through July, indicating it is still well-supplied. This reflects a tighter situation compared to the 400,000-ton surplus from the same timeframe last year in 2024. The tightening trend creates a tense balance between the fundamental surplus and fears of scarcity. For traders dealing in derivatives, this environment suggests volatility presents an opportunity. The clash between bullish headlines and the reality of a market surplus makes sudden price changes likely. Consequently, strategies that capitalize on large price movements, such as buying straddles or strangles on copper options, may be well-suited for the weeks ahead.
