NEW YORK, Sept 12 (Reuters) - Uncertainty over the future of troubled investment bank Lehman Brothers dragged down U.S. stocks on Friday, offsetting a rise in energy shares as oil climbed above $102 a barrel as Hurricane Ike headed for the Texas Gulf Coast.
The dollar also fell on uncertainty over Lehman, the No. 4 U.S. investment bank, and on data showing a second straight month of declines in retail sales.
The euro <EUR=> hit session highs as investors pared back dollar exposure over a weekend set to be pivotal to Lehman's <LEH.N> future.
Spot gold <XAU=> gained nearly 2 percent as the dollar declined, with the yellow metal's rally leading precious metals prices higher across the board [
] while U.S. Treasury bonds traded mostly lower as Wall Street stocks pared early losses, sapping safe-haven bidding for government debt.Concern that Lehman Brothers Holdings Inc may fail to find a buyer because the U.S. government is reluctant to provide financial backing sent the investment bank's shares tumbling to a nearly 14-year low on Friday.
Lehman's bonds also dropped ahead of what is expected to be a series of frantic calls this weekend between Lehman, U.S. regulators and potential bidders. Bank of America Corp <BAC.N> is widely seen as a leading contender, with British bank Barclays Plc <BARC.L> also cited as a possibility.
"Lehman is a proxy for the U.S. markets to some extent," said Jim Fehrenbach, head of Nasdaq trading at Piper Jaffray in Minneapolis. "Where Lehman goes so will the market in the short term."

The energy sector, meanwhile, was a bright spot as oil prices rose. An index on energy stocks was up 2.2 percent, and shares of Exxon Mobil <XOM.N> rose 1.1 percent at $76.67.
U.S. crude futures <CLc1> gained 36 cents at $101.23 a barrel, prompted by Hurricane Ike's threat to U.S. oil facilities.

> index of top European shares ended up 1.88 percent, snapping a three-session losing streak as higher metals prices sparked a strong rally in mining shares and energy stocks gained with oil prices..In currency trade, the dollar was down against a basket of major trading-partner currencies, with the U.S. Dollar Index <.DXY> down 1.01 percent at 79.017 from a previous session close of 79.822.

MARKETS IN THRALL TO LEHMAN
Bond markets were in thrall to the Lehman story, overshadowing news that U.S. consumer confidence soared unexpectedly to an eight-month high in September as lower fuel prices soothed inflation fears and made Americans more hopeful about the economy, the Reuters/University of Michigan Surveys of Consumers showed.
