NEW YORK/LONDON, March 5 (Reuters) - Gold rose more than 2 percent on Thursday, fueled by flight-to-quality buying as stock markets fell and investors saw a bargain in gold, which had retreated from above $1,000 an ounce last month.
Wall Street stocks extended their slide to 12-year lows on a warning of possible bankruptcy from General Motors and on mounting concerns about the banking system.
"Looking at the equity markets, we are a little weaker, which may help gold today," BNP Paribas analyst Michael Widmer said. "We are seeing support emerging after the sharp price falls of the past few weeks."
Spot gold <XAU=> was at $929.95 an ounce at 2:59 p.m. EST (1959 GMT), up 2.5 percent from its last quote of $906.90 late in New York on Wednesday.
U.S. gold futures for April delivery <GCJ9> settled up $21.10, or 2.3 percent, at $927.80 an ounce on the COMEX division of the New York Mercantile Exchange.
The Dow Jones industrial average <
> tumbled nearly 300 points, while the S&P 500 index fell 4 percent. Shares of Citigroup, once the world's largest bank by market value, traded below $1 for the first time.The yellow metal kept appreciating against a weaker equities market. The gold-to-S&P ratio jumped to 1.36, its highest level since 1990, Reuters data showed.
Gold was supported after the European Central Bank cut interest rates by 50 basis points as expected. ECB president Jean-Claude Trichet said inflation would remain below target this year and next.
The Bank of England cut rates by 50 basis points to a historic low of 0.5 percent, and said it would buy assets worth 75 billion pounds to help the UK economy. [
]"Today's cut in interest rates by the Bank of England (and) its decision to increase money supply in the banking system... will remind investors of the specter of future inflation and its eroding effect on wealth," said Marcus Grubb, head of investment at the World Gold Council.
CONSOLIDATION PHASE SEEN
But supply-demand fears kept a cap on enthusiasm for gold.
Buying has stalled from gold-backed exchange-traded funds. Holdings of the largest ETF, New York's SPDR Gold Trust <GLD>, remained at the level hit last Thursday. Its holdings have risen only 5 tonnes in the last fortnight, compared with 205 tonnes in the first six weeks of 2009. [
]On the supply side, dealers in Asia and the Middle East reported surging inflows of scrap as high prices lured sellers. Turkey imported no gold last month as domestic supply met needs, and Indian scrap selling is also picking up.
Gold has been in a consolidation phase as investors consider the outlook for other markets. The fear that drove the metal above $1,000 an ounce in February has been easing, analysts say.
"Steady support for gold came from investors who viewed the recent large decline as a buying opportunity," said George Gero, vice president of RBC Capital Markets Global Futures.
Among other precious metals, spot silver <XAG=> was at $13.23 an ounce, up 2.6 percent from its Wednesday finish of $12.90, while spot palladium <XPD=> was at $195.50, down 0.3 percent from its late Wednesday New York quote of $196.
Platinum prices inched higher after firming more than 1 percent on Wednesday on hopes China would ramp up plans to stimulate the economy. Spot platinum <XPT=> was at $1,060.00 an ounce, up 1.3 percent from its previous close of $1,046.
