COMEX copper futures edged higher in the Thursday session, recovering from Wednesday's sell-off as traders reassessed the Chile supply risk. The front-month contract settled at $6.549/lb ($14,438/mt equivalent), up 1.05% from Wednesday's close of $6.480/lb. The recovery suggests the market views the recent pullback as a buying opportunity given the structurally tight concentrate market.

LME three-month copper traded in a narrow range between $13,880 and $13,950/mt, closing at $13,920.5. The cash-to-three-month spread remains in modest backwardation, indicating nearby tightness. SHFE copper in Shanghai posted a 0.5% gain to 102,620 CNY/mt, tracking the Western markets.

Key to the move is the approaching mid-June wage negotiation at Codelco's Chuquicamata and El Teniente divisions. While current production continues without disruption, the union leadership has signaled willingness to strike if demands for profit-sharing increases are not met. Chile's copper output has already declined 3.2% year-to-date due to lower ore grades and water constraints.

Physical premiums in the Atlantic basin remain elevated at $95-110/mt above LME cash, with European consumers facing additional logistics costs from Red Sea rerouting. In China, Yangshan premium held steady at $48/mt, suggesting balanced import demand.

What this means for buyers

Copper buyers should consider fixing Q3 premiums now. The current backwardation and potential Chile disruption premium could widen spreads further. Spot purchases may carry a $95-110/mt premium over LME cash. Term contract negotiations for H2 2026 should factor in a potential 5-10% supply premium if Chile labor talks deteriorate.
