London copper prices hit a more than two-month low on Monday, as a stronger dollar made greenback-priced metals more expensive to holders of other currencies.
Three-month copper on the London Metal Exchange fell as much as 1.1% to $7,352 a tonne, its lowest since July 22 and down 32% since it hit a record high in March of $10,845 a tonne.
The US dollar hit a new two-decade peak, supported by a steep fall in the British pound and a hawkish outlook by the Federal Reserve.
With higher interest rates in sight, the global economic growth also looked shaky, threatening demand for industrial metals and pressuring prices.
LME aluminium hit an 18-month low of $2,151 a tonne, zinc eased 0.4% to $2,995.50 a tonne by 0326 GMT while tin rose 1.5% to $20,540 a tonne.
The most-traded October copper contract on the Shanghai Futures Exchange declined 2.7% to 60,840 yuan ($8,500.17) a tonne.
