SINGAPORE, April 6 (Reuters) - Brent crude fell below $122 a barrel on Wednesday from a 2-1/2 year high in the previous session, as a Chinese interest rate hike dampened sentiment, but widespread unrest in the Middle East will continue to underpin the market.
Brent crude for May <LCOc1> fell 28 cents to $121.94 a barrel at 0533 GMT after rising to $122.89 on Tuesday, the highest since August 2008.
U.S. May crude <CLc1> shed 13 cents to $108.21 a barrel at 0533 GMT.
Brent crude's premium to U.S. benchmark West Texas Intermediate crude <CL-LCO1=R> was at $13.72 a barrel, trailing record levels at $17.12 a barrel set on March 1.
"I expect Brent to remain on the uptrend. Technically, it is possible for Brent to go to $125 a barrel within this week." said Ken Hasegawa, commodity derivatives manager at Japan's Newedge brokerage.
"When Brent moves to $125, WTI could go above $110, although there is a small resistance now towards that level. After WTI goes above $110, it may accelerate and move towards $115 next week."
Brent's four-day rally to above $120 a barrel will soon fizzle out, a majority of traders and analysts said in a Reuters poll released on Wednesday, but it will roar back above $130 a barrel in the second half of this year. [
]China's central bank increased interest rates on Tuesday for the fourth time since October, raising speculation that data to be released next week by world's No. 2 oil importer may show inflation rose more than expected in March. [
]The increase comes before the European Central Bank is expected to raise its rates on Thursday for the first time since the global financial crisis, showing how inflation is rising to the top of the global policy agenda.
But market attention remains mainly on the Gulf and its widespread political turmoil.
MIDEAST UNREST
In Libya, a rebel spokesman said Gaddafi's forces bombarded Misrata again on Tuesday. Another rebel in Misrata said two people had been killed and 26 injured on Tuesday in mortar attacks. [
]Western powers have destroyed nearly a third of Gaddafi's military since launching air strikes last month but NATO said it was forced to change bombing tactics because of human shields. [
]In Yemen, President Ali Abdullah Saleh urged the opposition to join talks in Saudi Arabia to try to end weeks of turmoil and violence in which at least three more people were killed on Tuesday. [
]Separately, Kuwait's emir on Tuesday asked the outgoing prime minister to form a new government after the cabinet resigned to avoid possible questioning over the issue of unrest by Shi'ites in neighbouring Bahrain. [
]In Bahrain, firms have fired hundreds of mostly Shi'ite Muslim workers who went on strike to support pro-democracy protesters, an opposition group said on Tuesday, in what appeared to be part of a government crackdown. [
]Oil prices could rocket to $200-$300 a barrel if the world's top crude exporter Saudi Arabia is caught in the serious political unrest, former Saudi oil minister Sheikh Zaki Yamani told Reuters on Tuesday. [
]He said he saw no immediate signs of further trouble following protests last month calling for political reforms but added that underlying discontent remained unresolved.
Amid the widespread tension, the African nation of Gabon was able to resolve issues between workers and oil companies, which are expected to restore crude production shortly after an oil employees' union agreed to end a four-day strike. [
