London Copper Retreats From Record Highs
London Metal Exchange copper prices pulled back from record levels, dropping 0.6 percent to 14,625 dollars a ton in Shanghai. The wider industrial metals market declined as escalating hostilities in the Middle East introduced new headwinds following an all-time price surge. Despite the retreat, ongoing concerns about potential United States tariffs and tightening global supplies continue to support the metal. Meanwhile, global smelting margins have collapsed to zero, meaning smelters are losing money on every ton produced.
Why it matters
Copper prices recently reached historic highs driven by shrinking supply chains and expectations that the United States will expand tariffs to refined copper. This market pressure has caused physical copper to flow directly into the United States ahead of potential trade restrictions. The dynamic reveals intense tension between skyrocketing metal prices and the severe financial losses experienced by global smelters.
