LONDON, Nov 12 (Reuters) - Oil fell more than 2 percent to below $86 a barrel on Friday, retreating from a 25-month high reached in the previous session, as concern about Irish debt spurred a broad retreat from riskier assets.
Attention in the oil market refocused on risk aversion and macroeconomic concerns at the end of a week when prices were sent higher by oil's fundamentals -- Chinese demand at a record and U.S. inventories plunging.
U.S. crude <CLc1> was down $1.93 a barrel at $85.88 as of 0837 GMT, after touching an intra-day peak of $88.63 on Thursday, the highest since October 2008. ICE Brent <LCOc1> slid $1.57 to $87.24.
"It's just a correction after the big rebound the euro had against the U.S. dollar," said Ken Hasegawa, a commodity derivatives manager at Japan's Newedge brokerage.
"The big issue is the worries about Ireland's economy. It seems to be worse than expected, and that is the reason why the euro is falling. In addition, technically some selling orders have been triggered across all commodities."
The euro fell broadly on Friday, hitting a two-month low versus the Japanese yen and a six-week low versus the dollar on worries over Ireland's public finances and as positions in riskier assets were pared back.
