* Investors take profits after 2-month high
* Fed seen cutting rates by at least 50 basis points * SPDR ETF holdings inch higher (Recasts, adds detail, changes dateline, pvs SYDNEY)
LONDON, Dec 16 (Reuters) - Gold dipped on Tuesday as traders took profits after the previous session's two-month highs and as the dollar lifted from lows against the euro, but trading was muted ahead of a U.S. interest rate decision.
A decision by the Federal Open Market Committee to cut interest rates would augur well for gold.
Spot gold <XAU=> eased to $833.10/835.10 an ounce at 1044 GMT, down from $837.80 an ounce in New York late on Monday. The precious metal rose more than 2 percent in that session, hitting a peak of $844.20, its strongest level since October 16.
"There is a bit of profit taking after the big moves of recent days," said Stephen Briggs, commodities strategist at RBS Global Banking & Markets. "And we have had a slight coming off lows of the dollar versus the euro - that is still a key driver." Traders are now awaiting the Fed decision on interest rates, due at 1915 GMT. The FOMC is widely seen cutting rates by at least 50 basis points in an effort to stimulate the ailing U.S. economy. [
]Such a move would take rates to just 0.5 percent, their lowest in half a century. But even if the central bank opts for a smaller cut that necessary, it will still augur well for gold, analysts said.
"Whether the Fed cuts by quarter of a point, half a point, or three quarters of a point, it is all heading in the same direction, which is interest rates trending towards zero," Briggs said.
"That lowers the opportunity cost of holding gold and (adds to) the growing sense that all currencies are looking unattractive." He added: "The only alternative to currencies is gold."
The dollar firmed a touch against the euro after hitting a two-month low in Asian trade as investors eyed the Fed rates decision. [
]Gold is often bought as an alternative asset to the dollar and tends to move in the opposite direction to it.
The other main external driver of gold, oil, was a touch firmer, however, lending a little support to the market. Stronger oil prices support interest in commodities as an asset class, and can boost buying of gold as an inflation hedge.
ETF HOLDINGS FIRM
Interest in gold exchange-traded funds remains firm. The world's largest gold ETF, the SPDR Gold Trust <GLD> said its holdings rose by just over three tonnes on Monday. [
]Among other precious metals, platinum <XPT=> was steady at $821/841 an ounce, against $817 in New York late on Monday. Palladium <XPD=> was at $171.50/179.50 an ounce from $171.
Traders are awaiting more news on a mooted U.S. plan to bail out beleaguered carmakers, the main buyers of platinum.
Platinum reached parity with gold for the first time since 1996 on Thursday, and is holding just below the yellow metal.
"Platinum prices may fall further on worsening auto sales figures, but production cuts must surely start to turn the market around," Fairfax analyst John Meyer said.
"Platinum is significantly more expensive to produce than gold and its concentration in South Africa, where mining costs continue to rise, makes the metal sensitive to the South African rand."
"A weaker rand might help to keep price levels down but a weakening US dollar may not help this cause," he added. "Sooner or later platinum prices must surely pick up, unless we all suddenly convert to battery powered cars."
