 NEW YORK, Feb 23 (Reuters) - U.S. oil prices topped $100 a
barrel for the first time since October 2008 and investors
sought safety in bonds, gold and the Swiss franc on Wednesday
as the uprising in Libya fanned fears of inflation and slower
growth.
                                
 In London, Brent crude futures climbed above $110 a barrel

 The price of Brent posted the biggest three-day gain since
October 2009 as traders weighed the risk that popular revolts,
which have swept North Africa since January, could spread to
the big exporters in the Gulf.
                                
 "Oil prices are not likely to fall any time soon," said
Shelley Goldberg, commodities and energy strategist at Roubini
Global Economics in New York.
                                
 "It's not all about Libya, but a fear these movements will
spread further across the Middle East and North Africa region,"
she said.
                                
 The U.S. oil benchmark West Texas Intermediate touch highs

 Up to 25 percent of Libya's daily crude production of about
1.6 million barrels has been shut down, according to Reuters
calculations, helping to pressure oil prices.
                                
 U.S. light sweet crude oil <CLc1> pared gains after hitting
$100 a barrel, slipping to $98.01, up $2.71 for the day. Brent
<LCOc1> rose $5.53 to $111.30.
                                
 Despite the surge to the psychological barrier of $100, the
drag on the economy still might not be that great.
                                
 "Although higher oil prices at these levels would
negatively impact the economy, material damage wouldn't likely
occur until we moved above the $120 level," Chris Jarvis,
president of Caprock Risk Management in Hampton Falls, New
Hampshire.
