Copper fell 3.2% to $13,883 per ton on the London Metal Exchange on Tuesday, touching a three-month low, before recovering above $14,100 per ton on Wednesday. The move followed Democrats winning both chambers of Congress, which reduced expectations of US tariffs on refined copper.
Why it matters
Copper is essential to electrical infrastructure, so swings in its price feed directly into input costs for electrical contractors, equipment makers and anyone exposed to wiring and power-related materials. The decline came as the AI stock market rout shook confidence in the data-center spending boom, while lower tariff expectations removed a factor that had encouraged stockpiling in America.
Copper's one-day drop of 3.2% pushed it to $13,883 per ton, roughly 7% below its September record of $14,875 per ton. Chinese warehouse inventories have fallen more than 75% in six months, while the Yangshan premium remains near $200 per ton, its highest in over a decade.
The players
London Metal Exchange
The London-based exchange that serves as a primary global benchmark for trading base metals, including copper.
J.P. Morgan
A major global investment bank whose commodities research sets widely watched price forecasts for industrial metals.
The details
Traders had stockpiled copper in America in anticipation of tariffs, which drained supplies elsewhere and pushed prices higher. As the tariff outlook eased after the midterm results, that stockpiling incentive weakened, while investors selling on economic uncertainty continued to meet competition from physical buyers chasing limited supply. On the daily chart, copper remains in a descending channel after breaking its upward trendline, with the $6.31-per-pound area serving as critical support near July's low.
Timeline
July: copper hit the low that now serves as key support near $6.31 per pound.
September: copper reached its record high of $14,875 per ton.
Tuesday, November 3, 2026: copper fell 3.2% to a three-month low.
Wednesday, November 4, 2026: copper recovered above $14,100 per ton following the midterm elections.
Fourth quarter 2026: J.P. Morgan forecasts copper averaging $14,800 per ton.
Market Landscape
Copper's slide from its September record of $14,875 per ton to a three-month low illustrates how tariff-driven stockpiling in America can tighten supply elsewhere and then unwind once expectations shift. The move also reflects how confidence in the AI-linked data-center spending boom now competes with physical demand for copper as a metal central to electrical infrastructure.
Businesses that buy copper-intensive electrical components should watch for pricing movement as the metal trades in a descending channel, and procurement teams may want to review contract terms tied to LME benchmarks. Operators should also track whether the lower tariff expectations hold, since a reversal would change the cost outlook for refined copper inputs.
The takeaway
The key operating insight is that copper prices now reflect two competing forces: easing tariff expectations and softer confidence in AI-driven data-center spending, even as physical buyers keep bidding for limited supply. Operators buying copper-based inputs should track the $6.31-per-pound support level and the Yangshan premium as leading signals for near-term cost pressure.
