* Oil surges on Libya turmoil, prompting share sell-off
* Dollar, U.S. Treasuries get safe-haven flows
By Jeremy Gaunt, European Investment Correspondent
LONDON, Feb 22 (Reuters) - World stocks fell nearly 1 percent on Tuesday as revolt in Libya drove oil prices sharply higher, prompting fears of disruption to global economic growth.
Widespread risk aversion boosted the dollar and Swiss franc and prompted strong flows into U.S. Treasury bonds. U.S. stock index futures also tumbled, suggesting losses on Wall Street when it opens.
U.S. crude futures <CLc1> hit a 2-1/2 year high, rising close to 8 percent to more than $94 a barrel on the latest contract's last day of trading, as deadly clashes wracked exporter Libya's biggest cities.
Brent oil <LCc1> was up close to $2 a barrel at $107.60, somewhat shy of Monday's intra-day 2-1/2 year peak.
Libya is by no means the world's largest oil producer, ranking third in Africa after Nigeria and Angola, but investors are concerned about the spread of trouble and a serious disruption to supply.
"Investors are scaling down on exposure across the board," said Richard Falkenhall, currency strategist at SEB in Stockholm. "Libya is the first major oil exporting country to be affected ... if this spreads to other oil exporting countries, it will not be a good sign."
Adding to the uncertain mood, two Iranian ships entered the Suez Canal on Tuesday on their way to the Mediterranean, a move that is bound to anger Israel. [
]Investors are primarily concerned that Middle East/North Africa trouble will keep oil prices high, driving up inflation, cutting into corporate profits and crimping economic growth.
This could be seen most clearly on Tuesday in MSCI's benchmark emerging market stock index <.MSCIEF>, which was down 1.7 percent. Leading emerging market economies are among the fastest growing in the world and the most susceptible to inflationary pressure.
Globally, world stocks as measured by MSCI <.MIWD00000PUS> were down 0.9 percent. Europe's FTSEurofirst 300 <
> was down about 1 percent. Japan's Nikkei < > earlier lost 1.8 percent.^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

FLIGHT TO SAFETY
The risk-averse mood triggered a broad flight to safety. The yield on 10-year U.S. Treasuries <US10YT-TWEB> fell nearly 8 basis points to 3.505 percent. Yields on core euro zone debt <DE10YT=RR> lost 5 basis points to 3.131 percent.
"The situation in the Middle East is overshadowing everything else, and we've broken a series of technical levels on the way up," a trader said.
On foreign exchange markets, the dollar rallied broadly, up 0.6 percent against a basket of major currencies <.DXY> while the euro lost close to 1 percent to $1.3551 <EUR=>.
The euro <EURCHF=R> also fell 1 percent on the day to 1.2793 Swiss francs, pushing the traditional safe-haven currency to its strongest in three weeks.
Separately, the New Zealand dollar hit a near two-month low against its U.S. counterpart after investors fretted about the economic damage caused by a strong earthquake which rocked the country's second biggest city, spurring speculation about the chance of an interest rate cut.
