NEW YORK, Oct 9 (Reuters) - The U.S. dollar rose from a 14-month low on Friday after Federal Reserve Chairman Ben Bernanke said the U.S. central bank will be ready to tighten monetary policy, sparking a sell-off in bond markets.
Gold, which nearly always moves inversely to the dollar, eased after hitting record highs for three straight sessions as Bernanke's comments late Thursday lifted the dollar index, a basket of six other major currencies.
The U.S. Dollar Index <.DXY> rose 0.6 percent at 76.433.
The stronger dollar pushed oil down toward $71 a barrel and outweighed a positive demand outlook from the International Energy Agency, which earlier had lifted crude prices above $72. For details see [
].Bernanke's comments raised fears among investors that the Fed was closer to hiking interest rates than previously thought, sparking the biggest bond sell-off in over a month.
The benchmark 10-year U.S. Treasury note <US10YT=RR> fell 1-4/32 in price to yield 3.39 percent.
A lackluster U.S. 30-year bond auction on Thursday reminded both investors and officials that given a weak currency, foreign appetite for U.S. assets has its limits.
Bernanke "is still talking about an extended period of low rates but any time they use the tightening word it just brings to mind the fact maybe we're getting closer to the start of that whole cycle," said Rick Klingman, managing director of U.S. Treasury trading at BNP Paribas in New York.
U.S. stocks staged modest gains, lifted by supportive comments on technology bellwethers before key earnings reports are released next week. [

The Nasdaq Composite Index < > was up 8.99 points, or 0.42 percent, at 2,132.92.But Bernanke's comments also weighed on European shares, which closed lower. Even though the Fed's vast support for the U.S. economy will likely be needed for some time, it will have to remove those measures as the economy heals, to ward off any threat of inflation. [
]"It looks like the comments from Bernanke suggesting the Fed is positioning itself to raise rates at some point has been weighing on stocks. But I think it is a slight overreaction," said Peter Dixon, economist at Commerzbank.
The pan-European FTSEurofirst 300 <
> index of top shares closed down 0.3 percent at 998.17.Telefonica's <TEF.MC> disappointing results weighed on the telecommunication sector, and mining stocks fell, tracking a fall in metal prices.
Copper eased from three-week highs hit the previous session as doubts resurfaced over whether further gains are possible given prices have nearly doubled this year. Copper for three-month delivery <MCU3> on the London Metal Exchange traded at $6,250 a tonne.
"Bernanke put the brakes on the market by supporting the dollar," said Alex Heath, head of base metals at RBC Capital Markets.
U.S. crude for November delivery <CLc1> climbed 8 cents to $71.77 a barrel. London Brent crude <LCOc1> rose 9 cents to $69.86.
"The oil market today is sort of trying to balance the competing influences -- the dollar and the stock market. But at the end of the day it looks like the dollar's influence will hold after the greenback reacted to Bernanke's comments," said Brad Samples, an analyst at Summit Energy in Louisville, Kentucky.
The euro <EUR=> was down 0.55 percent at $1.4707, and against the yen the dollar <JPY=> was up 1.50 percent at 89.74 yen.
