NEW YORK, Jan 30 (Reuters) - Gold rose toward its record high above $930 an ounce on Wednesday as the dollar tumbled after the U.S. Federal Reserve aggressively slashed key interest rates and left more room for further rate cuts to boost the U.S. economy.
"This is certainly constructive. It weakens the dollar and it tends to be inflationary, so this is a plus for gold and I think it will help continue the upward trend that we've been seeing in gold," said Bill O'Neill, managing partner of LOGIC Advisors in Upper Saddle River, New Jersey.
"This is going to help all the precious metals and should help the copper market as well. And the Fed left open the possibility of further rate cuts. That was very significant," O'Neill said.
The Federal Reserve cut U.S. interest rates by a hefty half-percentage point on Wednesday as part of an aggressive effort to halt a sharp slowdown in an economy hit by a housing slump and a credit crunch.
Spot gold <XAU=> rose as high as $932 in afternoon trade, just slightly below its record high of $933.10 reached on Tuesday. It traded at $921.10/921.80 an ounce by New York's last quote at 2:15 p.m. EST (1915 GMT), versus Tuesday's New York close of $928.60/929.30.
In after-hours electronic trade, the active contract for April delivery at the COMEX division of the NYMEX <GCJ8> traded as high as $942.20, which marked a record high for gold futures.
"Today's policy action, combined with those taken earlier, should help to promote moderate growth over time and to mitigate the risks to economic activity. However, downside risks to growth remain," the Fed said in a statement, leaving the door open to future rate cuts. [
]A U.S. rate cut reduces the opportunity cost of holding dollar-priced gold and also tends to weaken the U.S. currency -- making bullion more attractive for non-U.S. investors.
George Gero, vice president of RBC Capital Markets Global Futures in New York, said in an email that the Fed's rate cut extended gold's rally as possible inflationary pressures were temporarily brushed aside by the Fed.
BULLION MOSTLY LOWER BEFORE FED
Prior to the Fed's rate announcement, bullion was mostly trading in the negative territory as investors took profits due to a mixed bag of data as a strong U.S. private employers job data countered a report showing weaker-than-expected U.S. fourth-quarter growth.
The supportive impact of crippled mine output in major producer South Africa faded as power was restored to some operations on Wednesday, but traders and analysts said the U.S. central bank's decision was the solid focus of the day.
Lower physical buying by India due to record prices has also taken a toll on market sentiment, but dealers contended that other factors, such as investment demand and the dollar, were more important now in driving the yellow metal.
"Right now, in my opinion, jewelry demand is not the primary force behind the rise in the metal. I think it's basically central bank buying from Asia and the Middle East countries in a move to dump the dollar. Ultimately I think the dollar is the major factor," Greenberg said.
Platinum <XPT=> dropped to $1,684/1,688 an ounce from $1,705/1,710 late in New York on Tuesday, when the metal spiked to an historic high of $1,735 an ounce.
Dealers said supply concerns persisted even though South African miners had resumed some operations on Wednesday after the state power firm promised to boost to boost supplies this week to mines crippled by outages. [
]Anglo Platinum <AMSJ.J>, the world's top platinum producer, said it had resumed mining at full capacity based on 80 percent power supplies to its operations, but was not concentrating, smelting or refining. [
]"Platinum is much more fundamentally driven than gold. The South African situation is critical, given it accounts for nearly 80 percent of (world) production," Dan Smith, metals analyst at Standard Chartered said.
In other bullion markets, the benchmark Tokyo gold futures <0#JAU:> ended 6 yen per gram lower at 3,182 yen.
Silver <XAG=> rose to $16.80/16.85 from $16.68/16.73 an ounce in New York and Tuesday's 27-year high of $16.80. Palladium <XPD=> dipped to $386/389 from its previous U.S. finish of $389/392. (Additional reporting by Atul Prakash and Veronica Brown in London)
