1. [para. 1][para. 2] Global copper prices have surged to a record high approaching $14,780 per ton, driven by an AI infrastructure boom and shifting global inventories. The most-active London Metal Exchange contract traded near $14,680 per ton on Wednesday, representing a gain of nearly 50% from roughly $9,800 a ton in September 2025—outperforming gold's rise over the same period by more than twofold.
2. [para. 3][para. 4] The sustained rally reflects a broader shift in commodities markets, as infrastructure demand tied to AI expansion and energy transition strains a tight mining supply chain. The latest price jump has been largely driven by regional buying in the U.S., where buyers have stockpiled inventories ahead of possible trade barriers. An earlier Commerce Department assessment on tariffs was due by June 30, and although the report hasn't been released, policy expectations have lifted international copper prices by more than 10% since July.
3. [para. 5] Inventory shifts were dramatic: COMEX copper inventories in New York climbed to 696,000 tons by Sept. 3, while LME inventories fell from 400,000 tons in mid-April to 237,700 tons by Sept. 8. Hengli Futures characterized the move as a structural rally driven by arbitrage flows and heavy U.S. stockpiling, noting that global refined copper supply has not materially contracted in the near term.
4. [para. 6][para. 7] Beyond trade distortions, electrification and large-scale AI deployment are reshaping copper consumption. Zijin Tianfeng Futures said copper is becoming a foundational industrial material in the new-energy era, comparable to oil's role in the combustion age. S&P Global Ratings estimated each megawatt of installed solar photovoltaic capacity requires 2.2 tons of copper, implying solar-related demand could reach 1.1 million tons annually with global installations reaching 600 gigawatts pre-2024. Grid expansion adds pressure: underground cables require 19.5 tons per kilometer, and S&P projects transmission-grid copper demand will double from 2020 levels to 7.1 million metric tons annually by 2040.
5. [para. 8] S&P estimated global computing capacity could reach 3.6 times 2020 levels by 2040, lifting data-center copper demand from 1.1 million tons in 2025 to 2.5 million tons by 2040. Guotai Haitong noted AI projects are relatively insensitive to copper prices—even at $15,000 per ton, copper would account for less than 5% of a data center's capital spending. However, Zijin Tianfeng warned that sustained high prices could encourage substitution with aluminum in U.S. overhead transmission lines.
6. [para. 9] In China, now in the first year of its 15th Five-Year Plan, copper is central to developing "new quality productive forces." The National Development and Reform Commission outlined six major infrastructure networks covering water, electricity, computing, communications, pipelines, and logistics, expected to drive over 7 trillion yuan ($1 trillion) in investment this year. Guotai Haitong estimated State Grid investment could rise more than 10% in 2026, creating nearly 320,000 tons of copper demand.
7. [para. 10][para. 11] Supply remains constrained. Soochow Securities said existing copper-mine reserves are declining; after prices fell post-2013, miners cut capital spending, and the typical five- to six-year development cycle impedes rapid capacity additions. Data from Founder Securities showed top 20 overseas copper miners produced 3 million tons in Q1 2026, down 4% year-over-year and 9% from the prior quarter. Treatment and refining charges fell to negative $181 a ton in August 2026, effectively forcing smelters to subsidize miners for raw materials.
8. [para. 12] Founder Securities expects supply constraints to persist through the rest of 2026, providing continued fundamental support for prices.
9. [para. 13][para. 14] Macroeconomic conditions have also bolstered copper. After the Fed cut rates by 25 basis points in September 2025 and again in October and December, LME copper futures rose from about $9,900 to $12,500 per ton, matching gold's gains. The metals diverged in early 2026: gold hit a record near $5,600 per ounce amid geopolitical tensions but retreated about 17% to around $4,400 after hawkish signals from new Fed Chair Kevin Warsh, while copper saw a brief spillover rally to $14,500 and a 7% pullback in March following the U.S.-Iran conflict, before recovering to trade near $14,800 per ton.
10. [para. 15] Unlike gold, increasingly shaped by geopolitical and credit concerns, copper tends to move positively with moderate inflation. Huatai Futures said such inflation typically reflects healthy economic conditions with firm consumption and investment, supporting elevated copper prices until the current cycle fades.
