NEW YORK, Nov 17 (Reuters) - Oil fell more than 2 percent to below $81 a barrel on Wednesday as worries persisted that China would raise interest rates to cool down inflation, curbing demand from the world's biggest growth engine.
U.S. government data showing an unexpectedly heavy drawdown in domestic crude stocks last week failed to stem a fourth day of decline in energy markets.
By 12:58 p.m. EDT (1758 GMT), U.S. crude for December delivery <CLc1> was down $1.60 at $80.74 a barrel, having dropped to a session low of $80.55, the lowest in more than two weeks.
U.S. crude prices have fallen about 7.7 percent in four sessions, the biggest percentage loss since a four-day decline to July 2. Prices are down from the two-year high of $88.63 hit on Thursday.
ICE Brent January crude <LCOc1> fell $1.02 to $83.71.
U.S. crude stockpiles fell 7.3 million barrels last week as imports dropped and refinery demand increased as more production units restarted after seasonal maintenance, data from the U.S. Energy Information Administration showed. [
]The data also showed larger-than-expected drawdowns in distillate supplies, which include heating oil and diesel fuel, and in gasoline inventories.
Even so, reaction to the bullish government report was muted as the industry group American Petroleum Institute reported late on Tuesday a 7.7 million barrel drop in domestic crude stocks last week.
DOLLAR SIDESTEPPED
Oil markets also shrugged off signals from the dollar, which fell against the euro and a basket of currencies <.DXY> as there appeared to be no clear-cut solution available to resolve Ireland's debt crisis in the euro zone. [
]In the usual correlation pattern, a lower value of the dollar sparks more risk-taking in the oil markets.
"After failing at Tuesday's close, bulls are shedding length and that is why crude hasn't received much support from the dollar's reversal today even with the inventory slide," said Stephen Schork, president at the Schork Group in Villanova, Pennsylvania.
Commodities and global markets have been hard hit in recent sessions on concerns involving China, the world's largest energy consumer. China has overtaken the United States to become the world's largest energy consumer.
Chinese Premier Wen Jiabao said his government was preparing steps to tame rising prices, the official Xinhua news agency reported late on Tuesday. [
]The tendency of China's central bank to raise interest rates around the 20th day of the month makes this coming Friday a "sensitive window" for a rate rise, an official newspaper said on Wednesday, citing unnamed analysts.
U.S. CPI, IRELAND
Further pressure came as the U.S. consumer index increased by a smaller-than-expected 0.2 percent in October. [
]The increase in the year-on-year core rate was the smallest on record, data showed, further supporting the Federal Reserve's decision to ease monetary policy through a gradual but massive purchase of Treasury bonds.
Irish debt problems continued to roil world markets, even though Ireland committed itself on Wednesday to work with a European Union-IMF mission on urgent steps to help its stricken banking sector, a process that could lead to a bailout despite reluctance in Dublin.
A team from the European Commission, the International Monetary Fund and European Central Bank will travel to Ireland on Thursday to examine what measures may be needed if Dublin decides to seek aid, euro zone finance ministers said.
