LONDON, Feb 24 (Reuters) - Oil prices hit 29-month highs on Thursday to near $120 a barrel on growing fears that the unrest in Libya could spread to other oil producing countries including top exporter Saudi Arabia, threatening to derail global growth.
World stocks and copper prices fell for the fourth straight day as investors cut their risk exposure, while safe-haven gold, Swiss francs and U.S. Treasury prices rose.
Libyan security has cracked down on anti-government protesters and fighting has spread to the capital Tripoli after erupting in Libya's oil-producing east last week with no signs of leader Muammar Gaddafi stepping down after 41 years in power. [
]Goldman Sachs said oil markets were driven by fears of unrest spreading to other producing nations and that another disruption could create severe oil shortages and require demand rationing.
"The market cannot accommodate another disruption, in our view, with the problems in Libya potentially absorbing half of OPEC's spare capacity," Goldman Sachs' Jeffrey Currie said in a research note. [
]Disruption stemming from the revolt in the world's No. 12 exporter Libya has cut at least 400,000 barrels per day (bpd) of the country's 1.6 million bpd output, according to Reuters calculations. [
]London Brent crude futures <LCOc1> rose 5.6 percent to trade above $117 a barrel after touching a 29-month high of $119.79, while U.S. crude futures <CLc1> advanced 4.3 percent to above $102 a barrel.
The surge in oil prices is threatening to put an end to the recovery in the developed economies and add further inflationary pressure in booming emerging countries.
According to UBS, a $10 increase in oil price will shave off 0.3 percentage points of global growth. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

GROWTH THREAT
"There has been another spike in oil and the general unrest in the Middle East has knocked all the confidence out the market," Mark Priest, senior equities trader at ETX Capital in London, said. "We cannot see a turnaround unless suddenly the situation is resolved in Libya."
World equities measured by MSCI All-Country World Index <.MIWD00000PUS> dropped 0.3 percent, falling for the fourth day in a row after hitting a 30-month high on Friday. The index is still up 2.3 percent this year.
MSCI emerging markets index <.MSCIEF> lost 0.9 percent to extend the loss for the year to 5.7 percent as investors shift out of developing economies to developed markets on concerns over higher inflation.
Europe's FTSEurofirst 300 <
> index lost 0.8 percent, while the VDAX-NEW volatility index <.V1XI>, a fear gauge, rose 6.5 percent to hit a two-month high. In Asia, Japan's Nikkei average < > fell to a three-week low, down 1.2 percent.
SHELTERS SOUGHT
The dollar was down 0.8 percent at 0.9257 Swiss francs <CHF=> and 0.7 percent at 81.91 yen <JPY=>, while the euro lost 0.6 percent to 1.2755 francs <EURCHF=>.
"There is a lot of safe haven demand for the Swiss and the yen but the dollar's downside against these currencies could be limited because for a lasting trend to arise you need U.S. Treasury yields to fall," said Manuel Oliveri, currency strategist at UBS.
Yields on benchmark 10-year U.S. Treasuries <US10YT=RR> eased 4 basis points to 3.4403 percent, down about 33 basis points from a nine-month high hit earlier this month.
Gold <XAU=> added 0.3 percent after gaining 0.9 percent in the previous session, though copper <CMCU3> eased 1 percent after falling 4.4 percent in the previous three sessions.
