Bloomberg reported that copper in London declined for a fourth day the longest period of decline since January as investors retreated on concern China may step up its credit tightening measures to cool asset prices.

The metal for three month delivery on the London Metal Exchange fell as much as 0.6% to USD 9,449.75 per tonne and trade at USD 9,450 in Singapore. It dropped to a one-week low of USD 9,443 per tonne.
