* Oil pares previous session's 3 pct gain on profit-taking
* Bernanke's comments help support U.S. dollar (Updates prices, add JP Morgan comments)
SINGAPORE, Oct 9 (Reuters) - Oil fell to $71 a barrel on Friday, following the previous session's gain of 3 percent, as the battered U.S. dollar firmed after U.S. Federal Reserve chief Ben Bernanke pointed to the chances for tighter monetary policy.
U.S. crude for November delivery <CLc1> dropped by 74 cents to $70.95 a barrel by 0701 GMT, after closing $2.12 higher on Thursday.
London Brent crude <LCOc1> fell 75 cents to $69.02 a barrel.
In comments that supported the dollar, Bernanke indicated monetary policy might have to be tightened as an economic recovery takes hold, adding the Fed could remove its easy money policies even while its balance sheet remained bloated. [

]A weaker greenback supports oil because dollar-priced commodities become cheaper for buyers using other currencies.
"Oil prices have spiked up too much, so there is some consolidation now. Continuous concerns of a weak dollar will keep crude oil supported," said Tony Nunan, a risk management executive at Tokyo-based Mitsubishi Corp.
Adding to the strength, Kuwait's finance minister said on Thursday oil trading would remain in U.S. dollars, the latest denial of a report this week of a move to replace the world's reserve currency with a basket of currencies. [
]The rebound in Asian shares to 14 month-highs on optimism over U.S. earnings and the global economy gave little support to crude oil prices.
Higher OPEC seaborne oil exports, excluding Angola and Ecuador, also weighed on the market. Such exports will rise 160,000 barrels per day (bpd) in the four weeks to Oct. 24, to 22.65 million bpd, according to Roy Mason, an analyst at British consultancy Oil Movement. [
]However, Venezuela said its total crude oil and refined product exports fell by 230,052 bpd to 2.328 million bpd in September, after rising in August. [
]While lower U.S. unemployment claims signalled a stabilising labour market, brimming fuel inventories in the world's top energy user remained a concern.
The U.S. Energy Information Administration (EIA) reported gasoline stocks leapt 2.9 million barrels last week, nearly three times the build that analysts had expected. Distillate stocks, including diesel and heating oil -- rose by 700,000 barrels. [
]JPMorgan said in a research note gasoline was likely to do refiners more harm than good in coming years, as demand had fallen nearly 340,000 bpd from its July 2007 peak.
"While our expected 16 percent fall in U.S. gasoline demand is impressive, we hesitate for now to link it to any larger trend in the global demand profile," it said.
"We expect global oil demand growth will be overwhelmingly centred outside of the United States in the coming years and greater U.S. efficiencies may have only a moderating impact on the overall global oil balance." (Reporting by Felicia Loo; Editing by Clarence Fernandez)
