SINGAPORE: London copper prices held steady as investors weighed a weaker U.S. currency and renewed concerns over the possible tariffs on the metal against support from declining inventories.

Three-month copper on the London Metal Exchange shed 0.29% to $9,589 per metric ton as of 0105 GMT.

The dollar index, which measures the U.S. currency against six major peers, fell to the lowest since late April.

A softer dollar makes greenback-denominated assets more affordable to holders of other currencies.

Meanwhile, on Friday, U.S. President Donald Trump announced his plans to double the import tariffs on aluminum and steel to 50% effective Wednesday, renewing concerns about potential copper tariffs.

“U.S. trade officials are currently reviewing the impact of U.S. copper imports on the local industry, with a report due in the next few weeks,” ANZ Research said.

“Copper is also finding support from improving fundamentals.”
