NEW YORK/LONDON, Aug 12 (Reuters) - Gold prices were on track to their biggest one-day rally in more than two months on Thursday as disappointing U.S. economic data further eroded investor confidence, prompting a surge of interest in perceived safe-haven assets.
Gold prices hit a four-week high amid a strong dollar and two days of sharp equity market losses after the Federal Reserve downgraded its economic outlook and said it needed to buy government debt to boost a flagging economy.
On Thursday, gold accelerated gains to rise about $10 in the minutes after data showed the number of U.S. workers filing new claims for unemployment insurance unexpectedly rose last week to a near six-month high, a fresh signal of a weak jobs market.
New York precious metals brokers said that buy stops were triggered after the jobless claims data, and as investors opted to cover their short positions to avoid losses as prices kept rising.
Gold <XAU=> was at $1,213.45 an ounce by 11:52 a.m. EDT (1552 GMT), against $1,197.00 late in New York on Wednesday, still nearly 5 percent below late June's lifetime high around $1,264.
Gold for December delivery on COMEX <GCZ0> was up $16.10, or 1.3 percent, at $1,215.30 an ounce. It was December's biggest one-day percentage gain since June 7.
Wall Street came under pressure for a second day after the jobless claims data, and after a NBC News/Wall Street Journal poll showed almost two-thirds of Americans believe the U.S. economy will worsen before it gets better. [
]"It's a combination of a macro environment being favorable to gold (and) actually physical demand has improved as well, so we would expect prices to gain some momentum," Barclays Capital strategist Suki Cooper said, adding that her team expected gold to average $1,260 an ounce in the final three months of this year.
The metal rose even as the dollar extended the previous day's strong gains due to risk aversion and weaker-than-expected Greek economic data. [
]Traders also cited a research note from Goldman Sachs, which upgraded its forecast for the gold price, as a driver to the rally in the price on Thursday.
"The recent sell-off has left speculative long positions in gold oversold relative to U.S. real interest rates, which we believe has set the stage for a rally to our six-month gold price target of $1,300/oz," Goldman said.
PHYSICAL GOLD DEMAND RISES
Although demand from key Asian consumers has been suppressed by the rise in gold prices over the past week or so, the desire for a safe haven as financial market volatility increases has translated into a rise in investment demand. [
]The world's largest gold-backed exchange-traded fund, SPDR Gold Trust <GLD.P>, said its holdings rose for the first time in a week. [
]Silver <XAG=> benefited from gold's rise, and was at $18.01 an ounce, up from $17.84 the day before.
Spot platinum <XPT=> was at $1,522.50 an ounce, down around 1.5 percent from the levels late in New York on Wednesday, but up from an intraday low of $1,500.75. Palladium <XPD=> was at $466.75, versus $477.00 Wednesday.
Asian traders said earlier the drop in PGM prices was a knee-jerk reaction to declines in equity markets. [
]However, investor sentiment in PGMs should receive a boost after General Motors [
] posted its biggest quarterly profit in six years. The top U.S. carmaker is also expected to file for initial public offering on Friday to raise $10 billion in equity, the biggest U.S. IPO since 2008. [ ] Prices at 12:16 p.m. EDT (1616 GMT)LAST NET PCT YTD
