Copper futures settled down on Tuesday on demand concerns after weak service sector data from the world’s top metal consumer China, despite stimulus efforts from the People's Bank of China (PBoC). The Caixin China services purchasing managers index slipped to 51.8 in August, down from 54.1 in July. Moreover, firm US dollar makes dollar-priced metals more expensive for buyers holding other currencies.
