脆弱供給下的需求擴散訴求

🔑 增強重點摘要

• •AI data center copper consumption is projected to reach 572,000 tonnes in 2028 (peaking mid-decade) before moderating, with cumulative locked-in copper surpassing 4.3 million tonnes by 2035—creating a structural supply constraint independent of broader electrification trends[2].
• •Global copper production will peak in 2030 at 33 million metric tons, then decline, while demand reaches 42 million metric tons by 2040, creating a 10 million metric ton deficit (25% below demand) unless mining capacity expands significantly[1].
• •Defense spending and humanoid robotics represent emerging demand vectors: defense demand alone is expected to triple by 2040, while 1 billion humanoid robots would require 1.6 million metric tons of copper annually (6% of current demand)[1].
• •The International Copper Study Group projects a refined copper shortfall of 150,000 tonnes in 2026, reversing previous surplus forecasts, with JPMorgan expecting prices to reach $12,500/ton in Q2 2026 and UBS projecting $13,000 by year-end[3].
• •China absorbs approximately 60% of global refined copper, with power infrastructure accounting for over 60% of demand growth through 2030, making Chinese manufacturing data and U.S. hyperscaler buildouts primary price direction indicators[4].

• •Hyperscale AI data center copper requirements: 40,000–50,000 tonnes per major facility for power distribution, grounding, and cooling systems[4][5]
• •Conventional data center copper usage: 5,000–15,000 tonnes; AI-ready campuses require 3–4× that amount due to higher power loads and advanced liquid cooling with copper heat exchangers[3][5]
• •Grid infrastructure demands: Hyperscale AI campuses require multiple redundant grid connections for uninterrupted power supply, with transmission lines, substations, and upgrades consuming large copper volumes[2]
• •Data center infrastructure spending trajectory: North American investment rising from $33 billion (2020) to $70 billion (2030) and $185 billion (2040), with each AI-ready site locking in thousands of tonnes of copper for decades[2]
• •Copper demand by sector through 2030: Electric vehicles use 80–100 kg per EV (vs. 20–30 kg for combustion vehicles); renewable energy and 5G infrastructure drive specialty metal demand[3]
