NEW YORK, Nov 12 (Reuters) - Oil prices slumped more than 3 percent on Friday, recoiling from a 25-month high, amid a broad commodities rout on fears that China may raise interest rates to brake its economy and concerns about the euro zone economy.
Profit-taking struck the market as traders said oil's near 8 percent gain over the past two weeks may have gotten ahead of fundamentals, despite news this week of record Chinese demand in October and big declines in U.S. crude and fuel stocks.
Volume was average, however, suggesting only moderate liquidation.
Friday's pull-back followed the biggest drop in the Shanghai composite index <
> in more than a year on the talk of Chinese interest rate increases after inflation sped to a 25-month high in October and bank lending roared past expectations. Earlier, China raised bank reserve requirements.U.S. crude for December delivery <CLc1> fell $2.80, or 3.19 percent, to $85.01 a barrel at 1:30 p.m. EST (1830 GMT), with total crude trading volume already above half million lots.
Prices were on track for a weekly loss after last week posting their strongest weekly percentage gain since February.
In London, ICE December Brent crude <LCOc1> fell $2.60 to $86.21 a barrel.
"Much of this liquidation appears prompted by growing expectations that China is poised for another interest rate hike," Jim Ritterbusch, president at Ritterbusch & Associates in Galena, Illinois, said in a note.
The International Energy Agency, an adviser to 28 industrial countries, predicted on Friday a slowdown in the rate of growth in global oil demand next year, while raising its forecast for this year, unsettling traders, who are looking for a more sustained recovery in global demand. [
]"When you look at the fundamentals, although improving during the week, they are not really supporting a very strong increase in oil prices as we have had," said Christophe Barret of Credit Agricole.
Oil vacillated, tracking the euro much of the day, deepening losses as the dollar bounced when greenback buying was sparked by the uptick in Treasury yields. [
]Prices of U.S. Treasuries fell on Friday as the first day of heavy purchasing by the Federal Reserve failed to jump-start wider demand for low-yielding government debt. [
]While euro zone debt concerns had been overshadowed by news from China and signs of improving fundamentals, commodity markets appeared to pay more heed on Friday.
Other commodity markets also plunged from multi-year highs, with Ireland's debt woes and this week's spate of exchange-imposed higher margin requirements adding to investors' growing risk aversion.

Concerns about Ireland overshadowed a Group of 20 leaders' summit in Seoul, where a breakthrough on resolving global economic imbalances amid incongruent policies looked unattainable. [
