LONDON: Copper prices dipped on Thursday after the U.S. Federal Reserve confirmed plans to tighten monetary policy sooner than expected.

Benchmark three-month copper on the London Metal Exchange (LME) was down 1.6% at $9,303 by 1100 GMT.
The Fed's switch to a more hawkish stance was signalled at the its June policy meeting, pushing the dollar higher and making assets priced in the greenback more expensive for holders of other currencies.
"The (Fed's minutes) saw a continuation of the sell-off that started June 16 when the Fed surprisingly sent hawkish signals by bringing forward rate hike projections," said ING analyst Wenyu Yao.
"Over the last two weeks the macro market is seeing a capitulation of reflation trade ... that is giving a lot of pressure to metals, especially copper."
China raised expectations that it could ease monetary policy to support its economy, which Saxo Bank analyst Ole Hansen said was interpreted by the market as sign of weakness in the world's top metals consumer.

The LME cash contract is at a $33 a tonne discount to the three-month price, pointing to plentiful supply.
