LME copper closes up $138 at $13,817/tonne; aluminium, zinc, nickel also gain

The breadth of the move matters more than copper's headline gain: aluminium, zinc, nickel and tin all advanced, with only cobalt flat, suggesting a broad base-metals bid rather than a single-metal story. That pattern points to macro or input-cost drivers lifting the complex together, which tends to matter for cost structures across industrial and battery supply chains. Whether the complex holds these levels in the next session, and whether cobalt's flat print is an outlier or a sign of diverging demand, is the open question worth watching.
