Three-month London Metal Exchange (LME) copper futures closed at $13,768 per metric ton on Nov. 6, their lowest close since late July. That figure is a closing price, not an intraday low. Market concerns included the possibility that a Democratic sweep could make U.S. copper import tariffs less likely. Traders also weighed the risk that tighter artificial-intelligence regulation could slow investment in AI infrastructure. The Nov. 6 close came three days after the [Nov. 3 intraday low]() of $13,883 per metric ton, copper’s lowest intraday level since Aug. 19. During that earlier session, futures fell below $14,000 per metric ton and were down 3.2% at their weakest point. Technology shares also declined as concerns about copper demand weighed on the market. ## Links in this article - [Nov. 3 intraday low](https://www.tokenpost.com/news/investing/47757)
