<h1>Copper futures jump as speculative buying, rate-cut expectations and major mine suspension tighten supply and lift prices</h1> Copper futures rose in domestic and international markets after speculators expanded positions and global cues firmed, with domestic October and September contracts gaining around 0.47-0.48%. Broker commentary attributed the rally to growing expectations of interest-rate cuts by a major central bank and to supply concerns following suspension of production at a large overseas mine after a mud flow blocked underground workings. The mine accounts for a material share of global output, and the reported disruption, together with tighter positions, reignited worries over industrial-metal availability that supported higher prices.
