Copper prices fell on Tuesday, pressured by a stronger dollar, while a rapid spread of the Omicron coronavirus cases worldwide also weighed on sentiment.
Three-month copper on the London Metal Exchange was down 1 percent at $9,619 a ton, its lowest level since Dec. 24. The most-traded February copper contract on the Shanghai Futures Exchange fell 0.5 percent to 69,760 yuan ($10,948.07) a ton.
The dollar index held firm, after rising 0.6 percent in the previous session, underpinned by a jump in Treasury yields overnight, as traders bet on an early US Federal Reserve interest rate hike.
