* Gold up on safe haven buying but off highs as oil plummets
* Crude dips more than $7/bbl as Lehman spooks investors
* Platinum, palladium plummet on fears over growth outlook (Adds comment, updates prices)

LONDON, Sept 15 (Reuters) - Gold rose on Monday on safe haven buying after Lehman Brothers filed for bankruptcy protection, but retreated from the highs it hit earlier in the session after oil fell sharply.
Platinum and palladium also tumbled as investors worried about the outlook for economic growth, amid fears Lehman's insolvency could destabilise the financial sector.
Spot gold <XAU=> was at $775.30/776.90 at 1427 GMT, up $11.85 from Friday's nominal close in New York but well off session highs of $784.90.
Traders say squaring of open positions in precious metals by Lehman and Merrill Lynch, whose takeover by Bank of America was also announced on Monday, could still push gold prices either way, however.
"We expect high volatility in the market in any direction," said Commerzbank senior trader Michael Kempinski. "We need a washout of all the positions which have to be squared."
"There is some safe haven buying going on at the moment, but when the banks have to liquidate their long positions... this may not appear in the price," he added.
Gold rose sharply earlier in the session as news broke of Lehman's bankruptcy, spurring buying of gold as a safe haven and pressuring the dollar. [
]A weaker dollar typically benefits gold as it boosts the precious metal's appeal as an alternative investment.
Traders were further spooked by news that Bank of America has agreed to buy Merrill Lynch, increasing fears over the stability of the global financial system. [
]But a sharp drop in oil prices has pressured gold more than $10 from its highs.
Crude fell more than $7 to well below $100 a barrel as investors sold oil in favour of safer assets, and as Hurricane Ike spared most Gulf of Mexico oil infrastructure. [
]Lower oil prices are reducing investors' interest in gold as an inflation hedge, analysts said.
"Crude oil is trading significantly below the $100/bbl mark, which is limiting the rebound of gold," said Dresdner Kleinwort in a note.
With the market still eyeing the dollar as the main driver of prices, however, dealers are awaiting the Fed's interest rates decision due on Tuesday for clues as to the future direction of the U.S. currency.
ETF SALES
Investor selling of gold held by exchange-traded funds is also knocking confidence in the precious metal, analysts said.
ETF Securities said on Monday that the amount of gold it holds to back its Physical Gold <PHAU.L> exchange-traded commodity fell 16 percent last week to 1.551 million ounces. [
]The world's biggest gold-backed ETF, SPDR Gold Trust <GLD>, said its holdings have fallen more than 37 tonnes, or 5 percent, since the beginning of September.
Among other precious metals, platinum and palladium headed lower after last week's bounce, tracking losses in the base metals as investors worried about the outlook for global growth.
"Platinum and palladium are following what is happening in the base metals, which looks like another round of selling, as people are increasingly concerned about the outlook for the economy in the United States," said Mitsubishi precious metals strategist Tom Kendall.
Spot platinum <XPT=> was down $50 or 4 percent at $1,152.50/1,182.50 an ounce, while palladium <XPD=> fell $12 or 5 percent to $230.50/240.50.
Spot silver <XAG=> was unchanged at $10.83/10.88 an ounce. Earlier it rallied 3 percent in line with gold to a session high of $11.15 an ounce. (Reporting by Jan Harvey; Editing by Editing by Peter Blackburn)
