NEW YORK, March 1 (Reuters) - Global stocks dipped on Tuesday as oil prices regained ground on worries about supply disruptions, fanning concerns about a dampening effect on economic growth.
Gold rose as escalating violence in Libya and unrest spreading across the Middle East boosted the precious metal's safe-haven appeal.
World equities, measured by the MSCI All-Country World Index <.MIWD00000PUS>, fell 0.3 percent. The index had gained 2.8 percent in February.
The U.S. dollar was down slightly against major currencies, while the 10-year U.S. Treasury note also was lower in price.
U.S. stocks, which are up about 26 percent since the start of September, declined despite data showing the U.S. manufacturing sector grew in February at its fastest rate since May 2004.
Federal Reserve Chairman Ben Bernanke, in testimony to the U.S. Senate Banking Committee, said higher oil prices were unlikely to have a big impact on the U.S. economy but could lead to weaker growth if sustained. For details, see [

The Nasdaq Composite Index < > was down 26.37 points, or 0.95 percent, at 2,755.90.High oil prices are "essentially a huge tax on consumers, who make up two-thirds of the economy. So there's no way (gross domestic product) won't suffer on this," said Scott Armiger, portfolio manager at Christiana Trust in Greenville, Delaware, which has $6.8 billion in client assets.
U.S. crude for delivery in April <CLc1> rose $1.71 to $98.67 a barrel, while Brent crude <LCOc1> was up $2.31 at $114.11 on continued concerns about supply disruptions amid unrest in Libya. [
]Oil, however, remained off its highs of last week, when Brent crude traded close to $120 per barrel, its highest in more than two years, due to concerns that political upheaval in Libya would spread across oil-producing nations in the Middle East. Saudi Arabia has calmed the market with extra supply. <^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ Graphic showing oil price shocks http://r.reuters.com/qes28r Calculator: Oil price impact on GDP

Spot gold rallied to a session peak of $1,424.01 an ounce -- its highest since Dec. 7, when it hit a record $1,430.95.
Gold in February staged its largest monthly rise since last August, as the turmoil in the Middle East fed demand for perceived safe-haven assets.
"What gold needed was a catalyst. It found it in the form of tensions that are surfacing in the Middle East and rising oil prices, which served as an inflationary threat and also led to political instability," said Mark Luschini, chief investment strategist of Janney Montgomery Scott, which manages $53 billion in client assets.
U.S. Treasury prices slipped as profit-taking unwound some of the market's recent safe-haven rally.
Benchmark 10-year notes <US10YT=RR> were down 8/32, their yields at 3.46 percent from 3.43 percent late on Monday.
The dollar index <.DXY>, which tracks the greenback's performance against a basket of major currencies, was up 0.01 percent after earlier hitting a 3-1/2-month low.
The euro gave up gains against the dollar after Bernanke noted in his remarks that downside risks to growth have declined and the risk of deflation was negligible. <EUR=>
Helping to support the view that China's monetary tightening was beginning to register, data from China showed manufacturing growth slowed in February while costs jumped. Analysts said more tightening would probably be needed to cool inflation due largely to rising oil and food prices. [
