Copper higher

Melbourne

London copper edged higher on Tuesday as the dollar eased from seven-month highs, while nickel found some support from data that showed a drop in mine supply.

Federal Reserve Vice Chairman Stanley Fischer said on Monday that the economic stability could be threatened by low interest rates, but it was "not that simple" for the Fed to hike, helping to drag on the dollar.

"Copper is being driven more by the global macro at the minute, particularly the USD, while the other metals are beating their own drums. Its fundamentals are not too bad," said analyst Daniel Hynes of ANZ in Sydney.

A weaker dollar boosts the purchasing power of commodities buyers paying with other currencies. Three-month copper on the London Metal Exchange rose 0.4 percent to $4,692 a tonne by 0251 GMT.
