Copper is the metal that moves electricity, and that makes it indispensable to everything the modern economy is building — power grids, electric vehicles, renewable energy systems, data centers and construction. No substitutes match its conductivity at comparable cost. Price is determined by the balance between mine supply, which responds slowly to price signals due to long development timelines, and demand from China, which consumes roughly half of global output. When Chinese construction and industrial activity is strong and inventory at exchange warehouses is falling, copper prices tend to rise; when Chinese growth slows or inventory builds, prices fall. The energy transition is a genuinely structural demand driver — an EV uses four times the copper of a conventional vehicle, and a wind turbine or solar plant requires significant copper in its electrical infrastructure. Supply constraints from declining ore grades and the difficulty of permitting and building new mines add a long-term supply tightness argument. For investors, copper is the best single commodity indicator of global industrial health and the most direct commodity exposure to the electrification megatrend.
