US Dollar Gains Weigh on Copper Prices, Overnight Copper Prices Close Lower [SMM Copper Morning Comment]

Published: Sep 29, 2026 09:12 (GMT+8)

SMM, September 29: Overnight, both LME copper and SHFE copper closed lower, with both showing long liquidation. Macro-wise, rising oil prices intensified inflation concerns, coupled with hawkish expectations from the US Fed. Copper prices are expected to consolidate on a subdued note within a narrow range today.

1. Overnight Futures

LME copper: Opened at $14,478/mt, hit a high of $14,481/mt, a low of $14,396/mt, and closed at $14,478/mt, down 1.05%. Trading volume was 19,000 lots, with open interest at 260,000 lots, down 2,650 lots from the previous trading day, as longs reduced positions.

The most-traded SHFE copper 2611 contract: Opened at 109,260 yuan/mt, hit a high of 109,370 yuan/mt, a low of 108,970 yuan/mt, and closed at 109,260 yuan/mt, down 0.16%. Trading volume was 31,000 lots, with open interest at 184,000 lots, down 1,545 lots from the previous trading day, as longs reduced positions.

2. Macro Front

The US rejected Iran's proposed peace deal, which was aimed at resolving the conflict between the two sides and reopening the Strait of Hormuz. The news pushed oil prices higher, reigniting concerns over rising US inflation. Combined with Fed officials maintaining a hawkish stance, the US dollar index closed higher, weighing on copper prices.

3. Fundamentals

Supply side, arrivals of both domestic and imported cargoes increased, easing the tightness in spot supply. Demand side, pre-holiday stockpiling has largely been completed, and with high premiums acting as a deterrent, downstream purchase willingness remained subdued.

Inventory-wise, as of Monday, September 28, SMM copper inventories across major Chinese regions rose 3,500 mt WoW to above 70,000 mt, while total inventories were 70,000 mt lower than the 140,000 mt level seen in the same period last year.

Unions at Chile's Centinela Copper Mine Vote to Strike; Second Beneficiation Plant Project Still Under Construction
SMM, September 29: Minera Esperanza and Distrito Centinela, two unions at Antofagasta's Centinela copper mine in Chile, completed their strike votes on September 28. The unions said all members eligible to vote participated in the ballot, with 98.73% voting in favor of a strike and rejecting the collective bargaining proposal put forward by the company. The dispute between the two sides mainly involves differences in pay and benefits among members of different unions. The mine has not yet halted production as a result of the vote, and the outcome of labor mediation still needs to be monitored. According to Antofagasta's disclosure, Centinela produced a total of 240,400 mt Cu in 2025, including 174,300 mt Cu in copper concentrates and 66,100 mt of copper cathode. The Centinela second beneficiation plant under construction at the mine has a designed ore processing capacity of 95,000 mt/day. The mine expects the project to come on stream in 2027, and after commissioning, it plans to add approximately 144,000 mt Cu of copper production per year. Whether existing mine production and the construction progress of the second beneficiation plant will be affected by labor negotiations remains to be seen.

Eldorado’s Skouries Copper-Gold Mine Completes Grid Energization Ahead of Q4 Commercial Production
Eldorado Gold announced on September 28 that its Skouries copper-gold mine in northern Greece has successfully completed permanent grid energization, following final inspection, testing and approval by the Greek transmission authority. The permanent connection replaces temporary on-site power used during early commissioning and provides the long-term electricity infrastructure required for continued plant ramp-up. Eldorado continues to target commercial production in Q4 2026. GlobeNewswire Skouries produced its first copper-gold concentrate on September 8, with crushing, grinding, flotation and concentrate/tailings thickening systems already operating. With permanent power now secured, attention shifts to increasing processing rates and achieving steady-state operations. The mine has an initial life of approximately 20 years and is expected to produce an average 67 million lb of copper annually, equivalent to about 30,400 tonnes, alongside 140,000 oz of gold over its mine life. The project represents one of Europe’s more significant new sources of copper supply, making its Q4 commercial-production milestone and subsequent ramp-up worth monitoring.
