London copper futures fell by more than 1%, but the weakness of the US dollar limited the decline.

On Wednesday, March 26, London copper futures fell as concerns over US tariffs weighed on market sentiment, but the decline in copper prices was curbed by a weaker US dollar.

At 13:59 Beijing time, LME three-month copper futures dropped 1.1% to $10,004 per mt.

The market focused on the new round of tariff measures to be announced on April 2, which triggered market tension.

The US dollar took a breather on Wednesday, as weak US consumer confidence data and concerns over the impact of large-scale tariffs on US economic growth dampened the recent rebound in the dollar.

When the dollar weakens, dollar-denominated copper futures become cheaper for buyers holding other currencies.

The market tracked copper inflows into the US ahead of the tariff decision.

Natalie Scott-Gray, senior metals analyst at StoneX, said, "I agree that there is a significant shift of metals to the US, where inventories are also increasing."

According to several of the world's largest trading groups, copper prices are likely to hit a record high of $12,000 per mt or higher this year.

For other LME base metals, three-month aluminum rose 0.13% to $2,613 per mt; three-month lead fell 0.7% to $2,070.50 per mt; three-month zinc dropped 0.2% to $2,966 per mt; three-month tin declined 1% to $34,695 per mt; and LME three-month nickel decreased 0.3% to $16,110 per mt.
