The US spot copper premium, which has held at a four-year high since July 2018, could come under pressure from an anticipated influx of Chinese material, market participants told Fastmarkets AMM. Fastmarkets AMM assessed the US copper cathode premium steady at 7-7.5 cents per lb delivered to the Midwest on Tuesday March 5; the premium is up by 26.1% from 5.5-6 cents per lb one year ago. „There is talk that a lot of copper [from] China might be coming to the warehouses, which would really put a damper on this struggling market,“ a US supplier said.
