LONDON, April 23 (Reuters) - Gold edged up on Thursday, extending gains from the day before as ongoing global economic concerns enhanced bullion's appeal as a hedge against market uncertainty, and physical buying in India also offered support.
Gold <XAU=> traded at $892.8/894 per ounce at 1156 GMT from $889.15 late in New York on Wednesday, up 0.4 percent. It rose 0.8 percent in the previous session.
But the market lacked momentum to push towards the key $900 mark, discouraged by stalling investment in the world's largest gold-backed exchange-traded fund (ETF).
"For gold to be really moving on the upside you've got to see more money coming into ETFs to justify that, and that has not been the case for some weeks now," Simon Weeks, director of precious metals at the Bank of Nova Scotia, said.
"I wouldn't say there's any more fresh demand coming in at the moment."
Holdings of the SPDR Gold Trust <XAUEXT-NYS-TT> have stayed at 1,105.98 tonnes, after investor outflows early this week reached their biggest since early September. [
]Some market players believe some funds may be looking at U.S. Treasury yields for clues about whether to invest in gold ETFs.
The benchmark 10-year U.S. Treasury yield <US10YT=RR> has stayed mostly between 2.5 and 3 percent this year, after plunging below 2.1 percent in late December as the global financial crisis deepened.
A 44 percent surge in the SPDR's holdings since the start of the year had helped underpin gold prices, but the last increase was nearly a month ago.
Gold-backed exchange-traded funds saw inflows of 456 tonnes in the first quarter of 2009, against a total 321 tonnes for the whole of the previous year, the World Gold Council said on Thursday. [
]Gold last closed above $900 on April 2 and fell as low as $864.00 on Friday, its lowest since Jan. 23.
DOLLAR WEAKER
A weaker dollar versus the euro also helped to support bullion, analysts said, as a lower U.S. currency makes gold cheaper for holders of other currencies. [
]And buying from India ahead of the Akshaya Tritya festival on April 27, an auspicious time for gold buying, continues to lend support.
Stock markets have recently indicated some glimmers of recovery, but gold has retained some appeal as a shelter from risk as global economic concerns nonetheless continue to abound.
The International Monetary Fund on Wednesday slashed its growth forecasts for every major country and urged governments to take forceful action to ensure the world economy's recovery from a severe recession. [
]Distress in the U.S. banking sector continues, with Morgan Stanley <MS.N> posting a wider-than-expected quarterly loss on Wednesday and cutting its dividend. [
]Among other precious metals, silver <XAG=> traded at $12.40/12.46 an ounce, platinum <XPT=> was at $1,178/1,186 an ounce and palladium <XPD=> traded at $230.5/235.5 an ounce.
"Should gold make a break lower, combined with base metals under pressure, both platinum and palladium could see a sharp decline in value," Standard Bank said in a note. "Auto demand alone would not support the price." (Additional reporting by Chikako Mogi in Tokyo; editing by Keiron Henderson)
