NEW YORK, Feb 28 (Reuters) - Major stock markets rose on Monday as worries eased about the effect of high energy prices on U.S. economic growth, while the dollar hit a 3-1/2-month low against a basket of major currencies.
World equities measured by MSCI All-Country World Index <.MIWD00000PUS> added 0.9 percent, after rising 1.1 percent on Friday. The global index is up 2.3 percent this month, on track for a third straight monthly rise.
Comments by James Bullard, president of the St. Louis Federal Reserve, that the U.S. economy should do well in 2011 and that oil prices are not currently a drag on the recovery helped boost U.S. stocks.
"If oil prices rise further it will restrain economic growth, but with no further escalations, at current levels it isn't going to cause a recession," said Jason Pride, director of investment strategy at Glenmede Investment and Wealth Management in Philadelphia.
The dollar, however, came under pressure on expectations that Fed Chairman Ben Bernanke, in testimony to Congress later this week, will stick with his recent economic assessment that the recovery is strengthening, but not enough to bring about a significant improvement in the jobs market.
The Dow Jones industrial average <
> was up 98.95 points, or 0.82 percent, at 12,229.40. The Standard & Poor's 500 Index <.SPX> was up 9.03 points, or 0.68 percent, at 1,328.91. The Nasdaq Composite Index < > was up 14.05 points, or 0.51 percent, at 2,795.10.U.S. stocks last week had their worst performance since November on worries about energy prices and the revolt in Libya.
Brent crude oil prices were volatile, following a spike last week on worries over supply disruption from the Middle East and North Africa. Brent crude <LCOc1> was last up 0.2 percent at $112.41.
The uprising in Libya has cut as much as three quarters of the country's oil output, prompting Saudi Arabia to step in and plug the supply gap to Libya's oil buyers.
Brent crude is up more than 10 percent this month, heading toward its sixth straight month of rises. It touched a 29-month high of near $120 a barrel last week.
The U.S. dollar fell versus a currency basket as investors speculated that Fed chief Bernanke will this week signal continued support for the central bank's quantitative easing program.
Bernanke's testifies to Congress on Tuesday and Wednesday, and expectations are that he will reiterate his view of an economic recovery that is still not strong enough to significantly reduce the jobless rate, suggesting the time is not ripe for U.S. interest rates to rise.
The ICE futures exchange's U.S. dollar index <.DXY>, which tracks the greenback's performance against a basket of major currencies, was down 0.6 percent. It earlier hit its lowest level since Nov. 9.
U.S. Treasuries prices remained steady at slightly higher levels after an index of Midwest business activity came in stronger than expected in February.
Benchmark 10-year note <US10YT=RR> yields stood at 3.42 percent, unchanged from late last week.
U.S. Treasuries earlier were supported by comments by the president of the New York Fed, William Dudley, that the U.S. central bank was "very far" from achieving its dual mandate of maximum sustainable employment and price stability and should be wary of withdrawing monetary policy support.
According to fund tracker EPFR Global, a growing aversion to risky assets in the latest week fueled the biggest flows to global bond funds in more three months, and turned more investors away from emerging market stocks. [
]The rotation out of emerging markets into developed markets, partly driven by inflation concerns in emerging economies, has led to outperformance in developed markets. The MSCI emerging market index <.MSCIEF> has lost 4.2 percent this year.
Credit Suisse's private bank expected the fund rotation to ease in the second quarter.
In Europe, the pan-European FTSEurofirst 300 <
> index of top shares was last up 1.1 percent at 1,172, extending gains after Bullard's comments on the U.S. economy.Copper prices also rose, helped by a weaker U.S. dollar and U.S. economic data, including the Midwest business activity report.
