NEW YORK, Jan 28 (Reuters) - Brent oil surged toward $100 a barrel on Friday and U.S. crude jumped more that 4 percent in heavy trade as unrest in Egypt rattled markets.
Brent pushed back above $99 a barrel to a 2011 peak as protests in Egypt and the government's response intensified and investors became increasingly wary about the turmoil. [
] [ ]"It's knocking on $100 a barrel. Whenever you have violence in the Middle East, you have (traders) buying on risk. It will come off as quickly as it got there," said analyst Andrey Kryuchenkov at VTB Capital in London.
Earlier, oil prices received a boost from news that the U.S. economy gathered speed in the fourth quarter, fueled by the biggest gain in consumer spending in more than four years and strong exports. [
]In London, ICE Brent crude for March <LCOc1> rose $2.08 to $99.47 a barrel at 12:59 p.m. EST (1759 GMT), having reached $99.74, eclipsing the earlier 2011 peak of $99.20 on Jan. 14.
U.S. crude oil for March delivery <CLc1> rose $3.59, or 4.19 percent, to $89.23 a barrel.
The bigger U.S. gains squeezed Brent's premium over its U.S. counterpart <CL-LCO1=R>, which had stretched to more than $12 per barrel, its widest since January 2009. [
]Total U.S. crude volume was above 1.06 million lots traded just after 12:45 p.m. EST (1630 GMT), according to Reuters data, nearing its record 1.432 million lots.
Total Brent trading volume was above 487,000 lots traded, according to Reuters data, 27 percent above the 250-day average.
"There is growing concern about the situation in Egypt and Yemen and there may be worry about not going into the weekend being too short," said Phil Flynn, analyst at PFGBest Research in Chicago.
The dollar and U.S. Treasuries rose and stocks fell around the globe as concerns that the protests in Egypt will intensify and spread across the Middle East drove investors to seek safer assets. [
