Three-month LME copper futures closed at $13,768 per metric ton on Nov. 6, the lowest close since late July. During the Nov. 3 session copper fell below $14,000 and was down 3.2% at its weakest point, which matters for businesses that buy copper-intensive inputs.
Why it matters
The decline reflects market concern that a Democratic sweep could make U.S. copper import tariffs less likely, alongside worries that tighter artificial-intelligence regulation could slow investment in AI infrastructure. For operators, shifting expectations about tariffs and tech-sector demand can move input costs for any business exposed to copper pricing.
Copper's Nov. 6 close of $13,768 per metric ton was its lowest close since late July, and its Nov. 3 intraday low of $13,883 was the weakest intraday level since Aug. 19. The metal fell below $14,000 during the Nov. 3 session, when it was down 3.2% at its weakest point.
The players
London Metal Exchange (LME)
The London-based exchange that lists the benchmark three-month copper futures contract used by industrial buyers and traders worldwide.
The details
Copper futures fell below $14,000 per metric ton during the Nov. 3 session as concerns about copper demand weighed on the market, and technology shares declined over the same period. Traders weighed two risks: that a Democratic sweep could make U.S. copper import tariffs less likely, and that tighter artificial-intelligence regulation could slow investment in AI infrastructure. Both factors feed into expectations for metal demand and pricing.
Timeline
Late July 2026: previous lowest copper close before the Nov. 6 move.
Aug. 19, 2026: previous lowest copper intraday level before the Nov. 3 low.
Nov. 3, 2026: copper hit an intraday low of $13,883 per metric ton.
Nov. 6, 2026: copper closed at $13,768 per metric ton.
Market Landscape
The Nov. 3 intraday low was copper's weakest since Aug. 19, and the Nov. 6 close was the lowest since late July, placing the November decline against the LME benchmark's recent trading range. The move is tied to trade-policy expectations for U.S. copper tariffs and to AI-infrastructure investment outlooks.
Businesses that buy copper-intensive inputs should factor in the possibility of continued price volatility tied to tariff and tech-demand expectations. Procurement teams may want to review their copper exposure and supplier pricing terms in the near term.
The takeaway
Copper's slide reflects expectations about trade policy and technology-sector demand rather than a single discrete event. Operators should track LME copper benchmark prices and any movement in U.S. tariff expectations as they plan input purchasing.
