Zinc prices on Wednesday rose to an 18-month high as a mine shut down in South Africa and signs that supply in the London Metal Exchange (LME) market is tightening added to expectations of strong demand from China, the top consumer. Benchmark zinc on the LME was up 2% at $2,743.50 a tonne at 1215 GMT after reaching $2,770, the highest since May 2019. The metal used to galvanize steel has risen more than 60% from a low in March as industrial activity in China rebounded from coronavirus closures. “There’s still room for Chinese metals demand to support prices and perhaps push them a little bit higher,” said Capital Economics analyst Kieran Clancy. “But the scope for further rallies is really starting to look more limited,” he said, pointing to rising coronavirus cases in Europe and the United States and the likelihood that China will dial back stimulus measures next year.
