Copper futures experience heavy selling pressure, dropping 2% to a six-week low near $6.40 after reaching an all-time closing high just four sessions ago. Uncertainty surrounding potential tariffs and the impact on global trade is weighing on the market, alongside building inventory stockpiles. A stronger U.S. dollar and higher interest rates are providing additional headwinds, sparking a broader shift in sentiment across the metals complex. Gold futures are down 1%, while silver has dropped 1.5% to the lower end of its recent trading range.
