Published: Oct 20, 2026 08:58 (GMT+8)

SMM, October 20: Overnight, LME copper closed up 0.09%, driven by bear position reductions; SHFE copper closed down 0.26%, driven by bull position reductions. LME inventory rebound and the end of an overseas copper mine strike eased supply concerns, while unrest in Europe pressured the euro and boosted the US dollar. As a result, copper prices are expected to consolidate on a subdued note in a narrow range today.
