* Fed signals no rush to scale back U.S. economic support
* But Fed will complete $600 billion bond buy as scheduled
* Dollar remains pressured (Recasts, updates prices, adds detail)
NEW YORK, April 27 (Reuters) - The U.S. dollar fell against the euro on Wednesday after the Federal Reserve said it will end its bond-buying program in June as planned and appeared in no rush to tighten monetary policy further.
The dollar fell to a three-year low against major currencies on Wednesday ahead of the announcement and remained pressured. For more see [
] and [ ].The spotlight now shifts to the 2:15 p.m. (1815 GMT) news conference by Chairman Ben Bernanke, the first regularly scheduled news briefing by a Fed chief in the central bank's 97-year history.
The Fed's super-loose interest rate policy is a source of severe trouble for the dollar, which has lost 10 percent of its value against a broad measure of major currencies since its January peak.
Low rates have combined with slow growth and an alarming budget shortfall, which led Standard & Poor's to change to "negative" from "stable" its outlook on the United States' prized AAA rating last week.
"Bit of dollar selling on the announcement as expected but respecting the day's ranges"," said John McCarthy, director of currency trading at ING Capital Markets in New York. "Nothing too much has changed. Still waiting for Mr Bernanke's Q&A."
The euro was up 0.4 percent at $1.4695 <EUR=> after reaching $1.4713, its highest since December 2009. The euro was at $1.4665 prior to the Fed announcement.
Traders said Asian and Middle East sovereign accounts were looking to buy the euro on every dip.
Market participants say a sustained break on the euro could open the way to the psychologically key $1.50 mark.
The dollar <.DXY> skidded to a three-year low of 73.493 against a currency basket earlier in the day, down around 10 percent from its peak in January, and many traders expect the index to fall to the all-time low, hit in July 2008, of 70.698. It last traded down 0.2 percent at 73.713.
"There is really nothing working in favor of the dollar right now," said Greg Anderson, G10 strategist at CitiFX in New York. "Rate differentials are working firmly against the dollar, we are in a risk-on environment and general dollar sentiment is overwhelmingly bearish," he said. "The Fed would have to turn substantially hawkish for the dollar to reverse course."
"Really the only positive for the dollar right now is the large level of shorts in the market," he said.
Yield differentials, however, favored the dollar over the yen, with Japan's central bank expected to keep interest rates low, perhaps longer than the Fed. The yen was one of the few currencies against which the dollar managed to gain, surging 1.1 percent at 82.43 yen <JPY=>.
The yen came under pressure after S&P downgraded its ratings outlook on Japan's sovereign debt. It warned the huge cost of last month's devastating earthquake would hurt already weak public finances unless the government raised taxes.
The euro jumped 1.5 percent to 121.12 yen <EURJPY=>. ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ For graphic on Fed funds rate hike expectations: http://r.reuters.com/xyz48r For graphic QE2 may flatten yield curve, stocks http://r.reuters.com/qyw78r For graphic QE with S&P 500 and 10-year TIPS yield http://r.reuters.com/faq98r ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
