Industrial metals like copper, aluminum, and nickel have seen significant price increases due to supply constraints and strong demand. Aluminum surpassed $3,000 per tonne, and copper neared all-time highs above $12,000 per tonne. These rising costs are impacting manufacturers of household goods, leading to planned price hikes of 5-8% for items like air conditioners and cookware. Supply issues stem from Chinese smelting caps, European production cuts, mining disruptions in key regions, and labor unrest.
