LONDON, Feb 1 (Reuters) - Gold hit session highs on Monday as the market fretted about rising price pressures after data showed manufacturing in the United States grew at a faster than expected rate.
Spot gold <XAU=> was bid at $1,095.80 a troy ounce at 1548 GMT compared with an earlier high of $1,097.55 and against $1,079.20 late in New York on Friday.
U.S. gold futures for February delivery <GCG0> on the COMEX division of the New York Mercantile Exchange were up $13.30 at $1,096.30 an ounce.
The Institute for Supply Management said its index of national factory activity rose to 58.4 in January from 54.9 in December and the prices component rose to 70 from 61.5. [
] [ ]"The ISM manufacturing number was good, there is the suggestion of inflationary pressures coming through," said Robin Bhar, analyst at Calyon.
Investors use gold as a hedge against inflation, which erodes wealth, while a higher dollar makes commodities more expensive for holders of other currencies. [
]Analysts said some recovery in risk appetite has benefited oil and U.S. and European stocks, which all rose after the ISM data. [
] [ ] [ ]Gold prices remain vulnerable to further losses, however, after falling 1.6 percent in January, analysts said, with the dollar's upward trend expected to resume.
"The dollar has been strong, and gold was always going to struggle on the basis of that," said Citigroup analyst David Thurtell.
"People have been seeking out gold as a currency hedge, and if that is no longer needed, that is going to cap some of the demand for gold."
ETF HOLDINGS DECLINE
Holdings of the world's largest gold-backed exchange-traded fund, the SPDR Gold Trust <GLD> were unchanged on Friday, but down 21.7 tonnes or 1.9 percent in January. [
]Holdings of the biggest silver ETF, the iShares Silver Trust, also declined 1.1 percent or 107.99 tonnes last month. Analysts said outflows from precious metals ETFs could undermine prices if they persist.
"Speculators and retail investors are still reluctant to re-enter the market, having booked profits during the latest correction," said VTB Capital analyst Andrey Kryuchenkov.
Among other precious metals, silver <XAG=> was at $16.41 an ounce against $16.16. Platinum <XPT=> was at $1,525 an ounce versus $1,500, and palladium <XPD=> was at $422 versus $413.
Holdings of ETF Securities' U.S.-based platinum exchange-traded fund <PPLT.P>, launched last month, rose just over 30,000 ounces or 14 percent on Friday, the company said.
Barclays Capital analyst Suki Cooper said during a conference call on Monday that she believes platinum group metals are set to outperform gold and silver this year.
"The launch of physically backed exchange-traded funds, coupled with expectations for auto sales to improve... is likely to bode well for PGMs, while expectations for the dollar to strengthen... are less positive for gold and silver," she said.
