Crude oil prices slip

World oil prices fell on Monday but held close to 92 dollars per barrel, with many traders away from their desks for Christmas holiday celebrations.
In London, Brent North Sea crude for February delivery slid 58 cents to 91.88 dollars per barrel.
New York's main contract, light sweet crude for February, gave up 38 cents to 92.93 dollars per barrel.
"Trading should remain rather subdued this week given the upcoming holidays," said MF Global analyst Edward Meir.
"Moreover, Friday's move may have gotten ahead of itself, especially now that key resistance levels are within sight," he added.
