NEW YORK/LONDON, March 10 (Reuters) - Gold lost more than 1 percent on Thursday, set to post its biggest one-day loss in about six weeks, as the dollar rallied and investors sold bullion to cover losses in equity and other commodity markets.
Gold retreated from its record high of $1,444.40 an ounce set earlier this week, as a cross-asset sell-off accelerated on Thursday. Both Wall Street and oil fell sharply after an unexpected Chinese trade deficit and renewed euro zone debt jitters fueled global growth concerns. [

The need to raise cash more than offset any safe-haven buying in gold, even as a downgrade of Spain's credit rekindled worries about the euro zone debt crisis. [
]"Spain's downgrade is clearly helping the dollar at this point. A few weeks ago, the story was everybody rushing into gold rather than the dollar, and now the tide seems to have shifted a bit," said Peter Buchanan, senior economist of CIBC World Markets.
Ongoing violence in Libya and rising political unrest across the Arab world also failed to lift gold despite worries about global economic growth because of oil's spike.
Spot gold <XAU=> fell as low as $1,402.72 an ounce, a two-week low, and was later down 1.6 percent at $1,406.20 an ounce by 12:45 p.m. EST (1745 GMT). U.S. gold futures for April delivery <GCJ1> fell 1.6 percent to $1,406.30.
On charts, spot bullion bounced off support after briefly falling below its 20-day moving average.
Tom Pawlicki, precious metals and energy analyst at futures broker MF Global, cited technical selling as gold this week has failed to clear key resistance at $1,435 an ounce -- the upper trendline of a long-term rising channel dated back from 2008.
Gold was hit as the dollar rose 0.5 percent against the euro after Moody's downgraded Spain to Aa2 from Aa1 with a negative outlook, leaving the euro vulnerable to more downward pressure in the coming weeks. [
]EYES ON EURO ZONE SUMMIT
Bullion investors will watch closely for possible development out of a Friday summit of a group of 17 euro zone leaders. The goal for the meeting is to boost competitiveness and to quell the region's debt crisis. [
]UBS said in a note that financial markets are likely to be disappointed by the outcome of the European meeting, which could benefit bullion.
"There is growing acceptance that Europe's debt crisis will get worse before it gets better, as our fixed income strategists maintain, and that this will be gold-positive," UBS said.
Among other precious metals, silver <XAG=> fell 3.5 percent to $34.79 an ounce.
Platinum <XPT=> slid 2.3 percent to $1,756.24 an ounce, while palladium <XPD=> lost 1.8 percent to $762.97. Prices at 12:45 p.m. EST (1745 GMT)
