Copper flat

Melbourne

London copper traded flat on Tuesday, as a stronger dollar capped gains after comments by a Federal Reserve official that boosted confidence in another U.S. interest rate rise this year.

London nickel found support after an Indonesian nickel smelting official said that 13 Indonesian smelters would halt operations after prices fell below their cost of production.

London Metal Exchange copper traded flat at $5,726 a tonne by 0555 GMT, following a 1 percent gain in the previous session.

Prices have found support around $5,645 a tonne and a ceiling around $5,800 a tonne. Shanghai Futures Exchange copper was up 0.8 percent at 45,950 yuan ($6,734) a tonne.

The dollar reached a more than three-week high versus the yen on Tuesday, after an influential Federal Reserve official said U.S. inflation should rise alongside wages, reinforcing expectations for the Fed to keep raising interest rates.
