Copper prices fell on Wednesday in Shanghai, as investors reduced risk exposure amid uncertainty caused by a power curtailment and ahead of a major holiday in China.
The most-traded November copper contract on the Shanghai Futures Exchange fell 0.9% to 68,600 yuan ($10,609.00) a tonne at 0300 GMT, while three-month copper on the London Metal Exchange dipped 0.1% to $9,264 a tonne.
Power restrictions in China have hurt supplies of some metals in recent months, but electricity curbs recently spread to more downstream sectors and dampened manufacturing, hurting the demand for metals.
Meanwhile, a stronger dollar also made greenback-priced metals more expensive and less appealing to holders of other currencies.
China is going on a week-long holiday starting Oct. 1, with investors squaring positions ahead of the break to reduce exposure in a volatile market environment.
