Copper fell the most in two weeks in London as increased government scrutiny of corporate debt in China, the biggest user, fueled concern that defaults by manufacturers will curb demand.
The National Development and Reform Commission began a special investigation last month into how some companies use bond proceeds, two people with direct knowledge of the matter said today. Copper futures posted the biggest loss in more than two years on March 7 after China’s first onshore default dimmed demand prospects.
“There’s a lot of concern about the weakness in China,” Phil Streible, a senior commodity broker at R.J. O’Brien & Associates in Chicago, said in an interview. “The risk of more defaults is really a huge factor” pushing prices lower, he said.
