SINGAPORE, Dec 1 (Reuters) - Oil rose on Wednesday on data showing factories in China revved up output in November, while Europe's debt problems and signs of rising U.S. fuel inventories capped gains.
China's official purchasing managers' index (PMI) climbed to a seven-month high in November, but rising input prices also signalled a need to tighten monetary policy to curb inflation, a move that would cut energy demand from the world's second-largest oil user. [
]U.S. crude for January <CLc1> gained 35 cents to $84.46 a barrel by 0612 GMT, after tumbling almost 2 percent on Wednesday. Prices still posted a third straight monthly gain, up by more than 3 percent in November, when they also touched a 25-month high of $88.63. ICE Brent <LCOc1> rose 33 cents to $86.25.
U.S. crude inventories fell by 1.1 million barrels in the week through Nov. 26, the American Petroleum Institute (API) reported on Tuesday, compared with expectations for a 900,000-barrel decline.
A drawdown of a bigger magnitude than that reported by the API "would bring oil inventories closer to their five-year average, which might provide the market with a positive impulse," said Stefan Graber, a commodities analyst with Credit Suisse in Singapore.
Inventories of distillates including heating oil and diesel unexpectedly rose by 224,000 barrels last week in top consumer the United States, according to the API.
Should the increase be confirmed in a government report from the Energy Information Administration (EIA) due on Wednesday at 1530 GMT, that would end a streak of nine consecutive weekly drops. The average forecasts from a Reuters poll of analysts is for a decline of 1.1 million barrels.
And gasoline stockpiles rose 1.1 million barrels last week according to the API, almost three times the projected 400,000-barrel gain.
U.S. consumer confidence rose in November to its highest in five months and U.S. Midwest business activity grew faster than expected, providing further evidence of economic recovery.
Still, a faster-than-expected fall in prices of U.S. single-family homes in September underscored the hurdles remaining for the recovery. [
