On April 23 (Thursday), the International Copper Study Group (ICSG) stated that, due to slowing demand growth and increased secondary copper production, the global copper cathode market is expected to shift to an oversupply of approximately 96,000 mt in 2026, reversing a previously forecast supply deficit of 150,000 mt.

The organization also forecast that the copper cathode surplus will widen to 377,000 mt in 2027, but warned that geopolitical risks including wars in the Middle East and shifts in trade flows could impact the market's supply-demand balance.

ICSG expects global copper cathode consumption to grow 1.6% in 2026, down from the previous estimate of 2.1%, with consumption growth forecast at 2% in 2027.

China's copper demand is expected to grow 1.9% in 2026, while demand growth in other regions is projected at 1.3%. ICSG added that copper consumption in the EU and Japan will remain subdued, while Asia will continue to be the primary driver of global demand growth.

In terms of supply, global copper cathode production is expected to increase only 0.4% in 2026, mainly constrained by limited copper concentrates supply, though increased secondary copper production will partially offset this constraint; with higher copper concentrates production and new capacity coming online, copper cathode production growth is expected to accelerate to 3% in 2027.

ICSG stated that global copper mine production is expected to grow 1.6% in 2026, down from the previous forecast of 2.3%, due to slower production growth in the DRC, Chile, and Indonesia, as well as operational constraints at the Grasberg and Kamoa mines following issues encountered in 2025.

The organization expects global copper mine production to grow 2.3% in 2027, supported by the gradual ramp-up of new capacity, improved production in Chile and Zambia, and higher mine utilization rates in Indonesia and the DRC.

Tight Supply of Cargoes with Invoices Dated This Month Drives Spot Premiums Higher, Pre-Holiday Stockpiling Expectations Provide Additional Support [SMM Shanghai Spot Copper]

[SMM Shanghai Spot Copper] Looking ahead to next week, from the perspective of invoice structure, the shortage of invoices dated this month at the domestic trade port intensified intraday, with suppliers generally raising their offer prices for cargoes with invoices dated this month, pushing SHFE copper spot premiums from discounts to premiums. Meanwhile, the price spread between cargoes with invoices dated this month and cargoes with invoices dated next month widened further, reflecting the continued disruption of the periodic invoice shortage on spot pricing. Affected by this, some downstream enterprises preferred to purchase directly from smelters to secure the issuance of invoices dated this month. Demand side, copper prices remain at elevated levels, and downstream purchasing has generally become cautious, dominated by rigid demand with limited willingness to chase higher prices. In addition, the Labour Day holiday falls next week, and some downstream enterprises have pre-holiday stockpiling needs, which may lead to a certain increase in purchasing, providing periodic support for spot premiums. Overall, under the combined effects of a tight invoice structure, pre-holiday stockpiling expectations, and high prices suppressing demand, Shanghai spot copper prices against the SHFE copper 2605 contract are expected to maintain premiums next week.
