William Adams, an analyst at BaseMetals.com, said demand for copper tubes was collapsing as producers switched to PVC plastics. The market in Germany has halved from 90,000 to 45,000 tonnes. "There's a very rapid switch from copper. When it turns, copper could easily drop $1,000 a tonne in one day," he said.
David Threlkeld, a veteran copper trader, said the market had been "out of control" for months, allowing speculators to run roughshod over industrial producers and users. "The LME has been seduced by hedge funds, [which have] pushed prices to levels unsupported by fundamentals. There's a vacuum below and the crash could set off a chain of margin calls running through the whole commodities sector. We've got a crisis on our hands and it is a lot bigger than copper," he said.
