LONDON, May 18 (Reuters) - Gold prices slipped on Monday as stock markets bounced, but analysts expect concerns about inflation and the economy to underpin the precious metal's credentials as a hedge against uncertainty.
Platinum rose after refiner Johnson Matthey released its influential annual report which highlighted expectations of strong Chinese jewellery demand, outweighing weakness in North American and European jewellery markets, traders said.
Spot gold <XAU=> was bid at $922.15 an ounce at 1402 GMT, compared with $930.70 late in New York on Friday, when it touched $933.65, its highest in seven weeks, after data showed U.S. core inflation in April rose more than expected.
A higher opening by U.S. stocks in the United States eroded gold market sentiment, but analysts said the impact was likely to be brief.
"The outlook for gold is a lot better than the outlook for the U.S. economy," said Charles Kernot, mining analyst at Evolution Securities. "There is still a lot of uncertainty in terms of the outlook for the global economy...People are now looking at it being a much slower recovery (than expected)."
Traders said rising oil prices <LCOc1>, which could feed an inflation spiral would help bolster gold market sentiment. [

PLATINUM EYED
Platinum slipped briefly after Johnson Matthey gave a wide range in the price forecast published in its annual report, saying prices could move between $950 and $1,350 over the next six months. [
]The report is the centrepiece of the annual gathering of leading figures in the platinum industry for the annual Platinum Week event in London this week. [
]Platinum <XPT=> later rose to $1,116 an ounce, compared with $1,100.50 an ounce late in New York on Friday. Platinum group metals languished in 2008 due to problems in the auto sector.
Johnson Matthey said demand from the auto sector, a major platinum user, and from the glass and chemical industries was set to decline this year as the economic downturn persists.
Palladium <XPD=> was bid at $223 from Friday's $222.50, while silver <XAG=> was at $13.71 an ounce from $13.93.
Johnson Matthey said palladium sales from Russian state stockpiles could keep the market in surplus for at least another year. [
]"For both platinum and palladium, the rapid ramp-up in ETF holdings has slowed significantly. As with gold, we believe the slowdown is due to the rally in equity prices since the middle of March," Standard Bank said in a note.
Investors were hesitant to pile more money into gold, keeping holdings at the world's largest gold-backed exchange-traded fund, SPDR Gold Trust <GLD>, unchanged at 1,105.62 tonnes as of May 15. [
