NEW YORK/LONDON, Feb 5 (Reuters) - Gold ended 1.5 percent higher on Thursday after the Bank of England cut its key interest rate, triggering strong investment demand amid renewed bank worries.
"We are seeing more investor interest in gold," said Citi analyst David Thurtell. "Some like it as a safe haven in times of high economic uncertainty, and others like it as a hedge against inflation.
"While deflation is the short-term threat, there is a concern that all this monetary and fiscal stimulus will eventually cause inflation to explode."
Shares of U.S. banks, led by Bank of America, initially tumbled on economic worries, but hopes that the Obama administration's plan would help banks stem losses led a broad-based stock recovery. [
]Spot gold <XAU=> was at $914.80 an ounce at 2:07 p.m. EST (1907 GMT), up 1.5 percent from the last trade of $904.70 on Wednesday.
U.S. gold futures for April delivery <GCJ9> settled up $12.00, or 1.3 percent, at $914.20 an ounce on the COMEX New York Mercantile Exchange.
Investors also fear the large amount of government debt poured into the banking sector will fuel inflation.
"The fact that gold as an asset class has more trust in it than a lot of other financial products out there at the moment means people are continuing to push money in there," said Commerzbank trader Rory McVeigh.
Options-related buying was also cited for the rally in gold futures.
Jonathan Jossen, a COMEX gold options floor trader, said that heavy buying of call options and deep out-of-the-money calls with a clear upside skew could be seen.
"A lot of people are saying when they are selling the bonds, and when they are buying the Dow, they are buying gold. Investors are putting a little more gold in their portfolio," Jossen said.
The Bank of England cut its rates by the expected half percentage point, in an attempt to revive the flagging UK economy. [
]"The backdrop of rate cuts has been supportive for gold over the last few weeks and months, mainly on the fear of inflation further down the line," said VM Group analyst Matthew Turner. "Today's moves were just a confirmation of that theme."
The ECB opted to leave its interest rates on hold at 2 percent. The bank's president, Jean-Claude Trichet, had already flagged that no rate cut was in the cards. [
]Interest in gold as a safe store of value is fueling buying among risk-averse investors.
The world's largest bullion-backed ETF, New York's SPDR Gold Trust <GLD>, said its holdings hit another record on Wednesday, rising to 859.49 tonnes. [
]SAFE HAVEN BUYING
Goldman Sachs lifted its three-month gold forecast to $1,000 an ounce from $700 an ounce, citing safe-haven demand for the metal. [
]"The gold price rally has been driven by surging demand for gold in all forms: physical gold, exchange traded funds and futures contracts and investors seek a 'safe store of value,'" the bank said in a note.
"It is also important to emphasize that the recent strong demand for gold has not been irrational, but rather pretty much in line with the probabilities of financial and sovereign default."
Silver <XAG=> was at $12.84 an ounce, up 2.6 percent from its previous close of $12.51 late in New York on Wednesday. Platinum <XPT=> was at $977.50 an ounce, up 1.4 percent from its last finish of $964.
Palladium <XPD=> was at $199.50 an ounce, up 2.8 percent from its previous close $194 on Wednesday. Earlier it rose nearly 5 percent to a high of $203.50, driven by buying for palladium-backed ETFs, dealers said. (Editing by Jim Marshall)
