LME base metals close mixed; copper up $149 at $14,232/t, cobalt down $555

The split between a broadly firmer base-metals complex and cobalt's sharp drop is the notable part: copper, nickel and tin all gained while cobalt alone broke lower by a wide margin. That divergence points to cobalt-specific pressure rather than a macro risk-off move across the LME. For anyone tracking battery-metals supply chains, cobalt's disconnect from the rest of the board is the thread worth following — whether it stays isolated or starts dragging other metals is the open question.
