LONDON, Nov 20 (Reuters) - Silver demand will creep up by 1% this year, reducing global oversupply of the metal to the lowest since 2015, consultancy Metals Focus said in a report. Slowing global economic growth amid an ongoing U.S.-China trade dispute has weakened demand for silver from some industries, according to the Metals Focus / Silver Institute Interim Silver Market Review. But this was offset by the higher use of sliver in electrical wiring in autos as vehicles become more sophisticated, by increased purchases by investors and strong demand for silverware and silver jewellery in India, it said.
