LONDON, Aug 18 (Reuters) - Gold prices were firmer in Europe on Monday, but retreated from highs hit in Asian trade as the dollar steadied against the euro.
The yellow metal climbed more than 2 percent to above $800 an ounce in early trade as the dollar slipped and oil prices rose, triggering a wave of short covering.
But the metal failed to hold on to those gains as the dollar steadied amid expectations it could be due another leg higher.
"Most of the gold price movement is strongly correlated with what is happening in the U.S. dollar," said Lehman Brothers analyst Michael Widmer.
"One thing that is keeping gold prices under pressure is the view that the dollar is going to be (stronger) going forward." Gold typically moves in the opposite direction to the U.S. currency, as it is often bought as a hedge against dollar weakness.
At 1013 GMT, spot gold <XAU=> was trading at $796.95/797.95 an ounce, up from $787.65/789.25 late on Friday in New York, but off its earlier session high of $803.65.
Gold slipped around $70 an ounce, or 8 percent, last week as a broad strengthening in the dollar led investors to sell commodities.
A wave of short-covering inspired by the weaker dollar and some bargain hunting pushed prices higher early on Monday. The dollar retreated from a six-month high against the euro as a recovery in oil and commodity prices arrested its recovery. [
]However, gold remains susceptible to further downward moves if the dollar resumes its upward trend.
"We are going to see a further retracement in the gold market, in particular on dollar strength," said Saxo Bank analyst Philip Carlsson.
"Even though the dollar has already (made) quite a large movement, people are predicting dollar strength will be the subject going forward."
An uptick in oil prices on Monday is also supporting prices. Oil rose more than $1 to above $115 a barrel as investors worried Tropical Storm Fay would disrupt supply in the Gulf of Mexico. [
]PLATINUM ETF HOLDINGS SLIP
Platinum firmed more than 5 percent in Asian trade, but has since slipped back to trade little changed from its level in New York late Friday.
The market remains under pressure from fears over demand from carmakers, which consume over half of the world's platinum every year.
London-based ETF Securities said holdings of its Physical Platinum <PHPT.L> exchange-traded commodity, which issues securities backed by physical metal, fell 30 percent in the week to Sunday, to their lowest level since February.
Its Physical Palladium <PHPT.L> ETC also saw an outflow of 10 percent, or just over 25,000 ounces. [
]Platinum <XPT=> was trading at $1,377.00/1,397.00 an ounce, up slightly from $1,365.00/1,385.00 in New York. Earlier it reached a session high of $1,438.00.
Meanwhile, spot palladium was trading at $283.50/291.50 against $281.00/289.00.
Among other precious metals, spot silver was at $13.11/13.16 an ounce against $12.74/12.84. Earlier it climbed almost 5 percent to a session high of $13.32 an ounce.
