NEW YORK, Dec 17 (Reuters) - Oil prices edged up on Friday, seesawing near $88 a barrel as currencies fluctuated amid fresh concerns about euro zone debt that helped limit gains in oil.
Refinery issues boosted U.S. gasoline futures <RBc1> and cold weather lifted heating oil futures <HOc1>, joining a report of supportive economic indicators to help keep crude oil firm, brokers and analysts said.
Ratings agency Moody's slashed Ireland's debt rating and put the country, along with Greece, on a negative outlook, warning that further downgrades could follow. [
]"After the market's rally above $90 (last week) it's trying to consolidate below, waiting for a cue as to whether we're going to see a year-end sell-off or whether more economic optimism is going to push crude higher," said Gene McGillian, analyst, Tradition Energy in Stamford, Connecticut.
U.S. crude for January delivery <CLc1> rose 17 cents to $87.87 a barrel at 12:07 p.m. EST (1707 GMT), having bounced off an $87.01 low before stalling after bouncing as high as $88.52. A finish above $87.79 would post a weekly gain ahead of the January contract's expiration on Monday.
Prices reached a 26-month high of $90.76 on Dec. 7.
"The recent long-side bias could likely be scaled back somewhat, as hedge funds seek to close out both the quarter and the year. This could result in prices working slightly lower as we head into the year-end," said Edward Meir, a senior commodity analyst at MF Global.
Technicals indicated crude could be set to slip to $85.41 over the next week, based on its wave pattern and a Fibonacci retracement analysis. [

ICE Brent crude for February <LCOc1>, in front-month position after January contract's expiration on Thursday, rose 9 cents to $91.69 a barrel, also in choppy trading.
The euro extended losses against the dollar to hit a two-week low after a drop below $1.32 triggered automatic sell orders amid pressure on the currency after Moody's warnings about Ireland. [
] The dollar index <.DXY> was stronger, but had seesawed.Oil and dollar-denominated commodities often move inversely to the dollar, with a stronger dollar typically pressuring oil prices as it raises the value of greenbacks paid to producers and raises the price of oil in markets using other currencies.
Moody's actions were viewed as an emphatic thumbs down on European Union leaders' failure to resolve the region's debt crisis and keep the contagion from spreading. [
]But the broad concerns were tempered by news that German business sentiment rose to its strongest level since 1991 in a closely watched survey by the Munich-based Ifo think tank. [
]Also keeping bulls hopeful was the view that the U.S. economy is gathering steam as 2010 draws to a close, based on data from two separate economic research firms on Friday.
The Conference Board's measure of leading economic indicators rose 1.1 percent in November, the biggest rise since March and the fifth straight monthly gain, while the Economic Cycle Research Institute said its gauge of future growth rose to its highest level since May. [
