标普：AI将使铜需求到2040年增长50%，需提高开采以确保供应

Group 1 - The core viewpoint of the report by S&P Global indicates that global copper demand is expected to increase by 50% by 2040, driven by the growth of artificial intelligence and the defense industry, while supply may face a shortfall of over 10 million tons annually if recycling and mining are not improved [2] - The report highlights that the demand for copper will rise significantly from 28 million tons in 2025 to 42 million tons by 2040, with nearly a quarter of this demand potentially unmet without new supply sources [2] - Factors contributing to this demand include global electrification, with copper being essential for various industries such as construction, transportation, technology, and electronics [2] Group 2 - The report notes that the conflict in Ukraine and increased defense spending in countries like Japan and Germany may further elevate copper demand [2] - Chile and Peru are identified as the largest copper mining countries, while China is the largest copper smelting nation, with the U.S. relying on imports for half of its copper demand [3] - The report does not consider potential supply from deep-sea mining, and it adopts the assumption that copper demand will rise regardless of government climate policies [4][5]
