Platinum rose to its strongest level in four months on Wednesday and sister metal palladium held near its highest since September 2011 on growing hopes the global economy was on the mend, while gains in equities hurt gold's safe-haven appeal.
Platinum and palladium have outperformed gold so far this year on an improving economic outlook, and after mining disruptions in South Africa as well as a drop in supply from Russia triggered fears of a deficit. Both metals are used in jewellery and auto catalysts.
Palladium is expected to set a record average high this year and platinum is seen posting its best price performance in two years as South Africa's supply problems worsen and the economic cycle starts to favour industrial metals, a Reuters poll showed.
Platinum hit a high of $1,714.75 an ounce and was at $1,712.99 by 0257 GMT, up $7.00. It powered to a record $2,290 in early 2008 after a power crisis in main producer South Africa disrupted mining and sparked fears of a supply deficit.
Palladium rose $1.05 an ounce to $764.49, after rising as high as 766.22 an ounce on Tuesday.
"It is quite clear that this year, the demand will (exceed) supply. I think we are seeing steady buying actually. There's a steady flow into those metals from investors all around," said Yuichi Ikemizu, branch manager for Standard Bank in Tokyo.
"I think we could try $1,750 for platinum and for palladium, the target is $800," said Ikemizu, referring to the short-term resistance levels.
Data showed on Tuesday the vast U.S. services sector expanded again last month, extending a three-year run of growth, while European business optimism hit an eight-month high, suggesting the euro zone economy is starting to recover.
Gold was little changed at $1,673.11 an ounce after it failed to sustain Tuesday's initial rise as U.S. stocks gained on stronger-than-expected earnings. U.S. gold was also little changed at $1,674.10.
Shares in Asia recovered on Wednesday as solid euro zone data calmed nerves jarred by potential political turmoil derailing the region's efforts to resolve its debt crisis, while the prospect of a dovish new governor for the Bank of Japan
