ICSG Copper Surplus Forecast Challenges Bullish Near-Term Market Narrative

Copper

ICSG copper surplus forecast has shifted the refined copper market outlook from deficit to surplus, challenging the more bullish tone around copper prices and strategic demand. The International Copper Study Group now expects a refined copper surplus of 96,000t in 2026 and 377,000t in 2027.

The revision marks a major change from ICSG’s October outlook, which had projected a 150,000t deficit for 2026. The new ICSG copper surplus forecast reflects weaker-than-expected demand growth and stronger secondary refined copper output.

The refined copper market is still exposed to mine disruption, lower ore grades and geopolitical risk. However, the latest forecast suggests that scrap-based production and slower consumption can offset some of the tightness from constrained mine supply.

ICSG expects global adjusted mine production to reach 23.559mn t in 2026 and 24.103mn t in 2027. Adjusted refined production is forecast at 28.76mn t in 2026 and 29.613mn t in 2027, while refined usage is expected at 28.664mn t and 29.236mn t.

Secondary Output and Slower Demand Ease Refined Copper Tightness

The biggest change in the ICSG copper surplus forecast comes from the refined side of the market. Stronger secondary output is expected to help balance constrained primary supply.

Refined copper production is forecast to grow by only 0.4% in 2026 before rising by 3% in 2027. Constrained concentrate availability will limit primary electrolytic growth this year, but solvent extraction-electrowinning and scrap-based output should provide support.

For 2027, ICSG expects primary refined copper production to rise by 2.3%, while secondary refined production increases by 5.7%. This gives scrap a larger role in balancing the market.

This matters because copper supply discussions often focus heavily on mines. But refined copper availability also depends on scrap collection, processing economics, smelter operations, SX-EW output and regional refined production.

Demand growth has also been revised lower. ICSG now expects refined usage to increase by 1.6% in 2026, down from its previous 2.1% forecast.

The downgrade reflects uncertainty from the Middle East conflict and disrupted trade flows. Chinese refined copper usage is expected to rise by 1.9% in 2026, while demand outside China grows by 1.3%.

Global refined usage is forecast to rise by 2% in 2027. Asia will remain the main growth engine, while EU and Japanese consumption are expected to stay subdued.

Asia outside Asean and CIS states will remain by far the largest refined copper-consuming region. Usage is projected at 20.469mn t in 2026 and 20.907mn t in 2027.

Mine Supply Risks Still Support Copper’s Strategic Value

ICSG’s near-term surplus forecast does not remove copper’s longer-term supply risk. The group revised down its 2026 mine production growth forecast to 1.6% from 2.3%, citing weaker growth in the Democratic Republic of Congo, Chile and Indonesia.

Output at Grasberg in Indonesia and Kamoa in the DRC remains constrained after major incidents in 2025. These disruptions show how quickly copper mine supply can tighten when large assets underperform.

Mine production growth is expected to recover to 2.3% in 2027. ICSG expects support from Chile, Zambia, Indonesia and the DRC, along with ramp-ups at Oyu Tolgoi in Mongolia, Malmyz in Russia, Julong in China and Almalyk in Uzbekistan.

Still, mine supply remains structurally difficult. Declining ore grades, slow permitting, higher capital intensity and longer project timelines continue to limit how quickly the industry can respond to higher prices.

Copper demand also retains strong strategic drivers. Energy transition investment, grid expansion, urbanisation, digitalisation, data centres and new semi-finished product capacity should continue to support long-term consumption.

This creates a split market narrative. On paper, refined copper may move into surplus in 2026 and 2027. Strategically, copper remains central to electrification, artificial intelligence infrastructure, manufacturing and industrial policy.

ICSG also warned that actual balances could diverge from forecasts. Its Chinese apparent demand calculation excludes changes in unreported stocks, including State Reserve Bureau, producer, consumer, trader and bonded inventories.

That caveat is important. Copper inventories can move through hidden channels, making the refined market appear looser or tighter than reported balances suggest.

The ICSG copper surplus forecast therefore does not end the bullish long-term copper case. It does, however, caution against assuming immediate refined scarcity when secondary supply is rising and demand outside China remains soft.

The Metalnomist Commentary

The ICSG copper surplus forecast shows that copper’s strategic story and near-term balance sheet can move in different directions. Data centres, grids and electrification support the long-term thesis, but scrap growth and weaker demand may keep the refined market looser than bullish headlines suggest.
