Copper prices surged by nearly 5% following the declaration of force majeure by the operator of Indonesia’s Grasberg mine due to an accident. This incident has exacerbated concerns over supply shortages, especially as treatment and refining charges at copper smelters have dropped indicating a scarcity of raw materials.
The International Copper Study Group reported that mine production in the first seven months has improved, driven by Chile, Peru, and the Democratic Republic of Congo. However, production from Indonesia decreased by 32% due to ongoing issues at the Grasberg mine. Overall, global mine production rose by 3.4%, with metal production increasing by 3.9% compared to the previous year.
Despite growing global demand, led by China which consumes about 60% of copper, there is still a supply surplus of 100,000 tons. This figure, though, is a reduction from the 400,000 tons surplus recorded last year, indicating the market remains well-supplied but less so than before. Experts suggest that production may not increase as much as in previous years, yet it is predicted to stay elevated.
The recent 5% price spike in copper shows just how sensitive the market is to supply news, such as the disruption at Indonesia’s Grasberg mine. This event has pushed London Metal Exchange (LME) copper prices to hover around $9,200 per metric ton, a level that reflects market anxiety over potential shortages. We see this as a clear signal that headline risk will be a major driver of volatility in the weeks ahead.
This nervousness is amplified by the collapse in treatment and refining charges, which have fallen to historic lows under $5 per ton from over $80 per ton this time in 2024. Such low charges typically indicate a fierce competition for raw copper concentrate, fueling the narrative of a supply shortage. This market signal is powerful, creating bullish sentiment even when broader data suggests otherwise.
Despite these fears, we must recognize that global mine production actually increased by 3.4% in the first seven months of this year. Increased output from major producers like Chile and the Democratic Republic of Congo has more than offset the 32% production drop from Indonesia. This underlying supply resilience suggests that the fundamentals are not as tight as the recent price action implies.
On the demand side, China continues to be the primary engine, accounting for about 60% of global consumption. The country’s demand is largely driven by its green energy transition, with sales of electric vehicles up 25% year-over-year through August 2025. Still, this robust demand has not been enough to completely absorb the growth in production.
The data shows the global copper market had a supply surplus of 100,000 tons through July, meaning it remains well-supplied. This is a significantly tighter balance compared to the 400,000-ton surplus we saw for the same period last year in 2024. This tightening trend creates a tense dynamic between a fundamental surplus and a sentiment-driven fear of scarcity.
For derivative traders, this environment suggests volatility is the main opportunity. The conflict between bullish headlines and the reality of a market surplus makes sudden price swings in either direction likely. Therefore, strategies that profit from significant price movement, such as buying straddles or strangles on copper options, could be well-suited for the coming weeks.
