The price of copper on the London Metal Exchange fell 0.4% to $13,786 a ton, reaching a new low since July, Bloomberg reports. The drop in quotes is related to the results of the US congressional elections: market participants expect that the Democrats' victory will lead to a tightening of the regulation of the artificial intelligence industry and a slowdown in the construction of data centers. In addition, a change in policy reduces the likelihood of introducing import duties on metal, which previously supported high prices in the American market.
