LONDON, Feb 18 (Reuters) - Oil prices moved lower on Friday after China increased lenders' reserve rates, although a background of continued geopolitical tension in the Middle East and North Africa lent support.
Brent crude futures <LCOc1> fell 5 cents to $102.54 a barrel by 1245 GMT, down from earlier gains to $103.5 a barrel. U.S. March light crude contract <CLc1> shed 14 cents to $86.50.
China raised banks' required reserves by 50 basis points on Friday, the second such increase this year as it continues the fight against inflation, and fanning fears this could signal a curb in its oil demand growth. [
]"They have been trying to curb liquidity for some time so little surprise and not as bad as a benchmark rate rise, but still slightly weighing on sentiment," Andrey Kryuchenkov from VTB Capital said.
Despite China's bearish move, analysts said Brent futures prices could be supported going into the weekend.
"We suspect that the markets will be fairly well bid heading into the weekend, as developments in the Middle East should prevent aggressive short positions from building up," MF Global analyst Edward Meier said in a note.
"It will likely be Brent that will likely see the most price sensitivity in the event of a serious flare-up, as WTI still seems to be on the defensive."
Tensions in the Middle East were in focus after Egypt said on Friday it had received a request for Iranian naval vessels to pass through the Suez Canal, a move Israel's right-wing foreign minister has described as "provocative."
"We sent it to the relevant authorities," the Foreign Ministry spokesman told Reuters, adding the request had been passed to the Defence Ministry and the Suez Canal Authority. [

G20 ALSO IN FOCUS
Investors were mulling data from the European Central Bank showing that overnight emergency funding reached 16 billion euros on Friday, the second consecutive day, and the highest level since June 2009. [
]The news flagged fresh concerns over the health of the European banking system as finance ministers and central bankers from the Group of 20 meet in Paris to discuss the global economy and commodity price inflation over the weekend. [
]The U.S. Federal Reserve Chairman Ben Bernanke, ECB President Jean-Claude Trichet, the Bank of Japan's Masaaki Shirakawa, the Bank of England's Mervyn King and People's Bank of China head Zhou Xiaochuan will speak at an event in Paris at around 1430 GMT.
The debate concerning crude benchmarks continued as the spread between Brent and U.S. light crude <CL-LCO1=R> traded at around $13.66 by 1213 GMT.
Nomura's Michael Lo argued the change in global oil demand growth was playing a role in the weakness of the U.S. light crude, also known as West Texas Intermediate (WTI).
"Future oil demand growth will likely come from the Asia Pacific region, and new refineries are being built in this region to meet new demand. WTI plays almost no part in this region and the demand and supply dynamics are very different," Lo wrote in a note. "Brent is increasingly being recognised as a crude benchmark in Asia."
The U.S. light crude contract could benefit from short-covering ahead of expiry of the March future on Tuesday.
Brent oil prices are forecast to drop later this year as analysts expect the risk premium for unrest in the Middle East to ebb, a Reuters poll showed. [
