Copper benchmarks set records

Concern that copper demand by China, the world's largest user of the metal, will outstrip supply sent copper futures in Shanghai to their highest level since trading began 12 years ago, Bloomberg reported. Copper on the Changjiang Nonferrous Metals Spot Market, which sets price benchmarks, also reached a record price record, climbing to RMB34,960 a ton, the highest since the market began trading in 1994.
