NEW YORK, Feb 24 (Reuters) - Crude oil prices soared to almost $120 a barrel and the safe-haven Swiss franc hit a record high on Thursday as the turmoil in Libya kept markets tense, but gold and Wall Street even edged higher.
The escalating violence in Libya, home to Africa's largest proven oil reserves, lifted benchmark Brent crude oil to its highest price since August 2008 and kindled investor fears of an inflationary spike that might slow global economic growth. For details see: [
]This week's relentless surge in oil prices stung the U.S. dollar against major currencies, boosting the Swiss franc and to a lesser extent the Japanese yen, currencies that often benefit during times of uncertainty. [
]Copper, considered a harbinger of economic sentiment, fell to one-month lows but gold steadied near seven-week highs as investor fears over oil-induced inflation were partially offset by pockets of profit-taking. [

"The focus is on the Middle East and oil prices. Everybody and his mother has upgraded their forecasts on oil prices, with one even forecasting oil to hit $200 per barrel," said Ron Simpson, director currency research at Action Economics in Tampa, Florida.
Forces loyal to Muammar Gaddafi launched a counter-attack but rebels threatened the Libyan leader's grip on power by seizing important towns close to the capital and bringing the tide of rebellion ever closer to his power base. [
]Disruption to Libya's output has cut at least 400,000 barrels per day of the country's 1.6 million barrels per day production, Reuters calculations show. [
]Italian oil company ENI said the decline was greater, estimating 1.2 million barrels of oil had been removed from the market.
