TOKYO, June 4 (Reuters) - The dollar drifted on Wednesday, holding big gains against the euro and other major currencies racked up the previous day when Federal Reserve Chairman Ben Bernanke issued an explicit warning about the inflationary threat from a weak U.S. currency.
Bernanke said the weak dollar was adding to price pressures and that the Fed along with the U.S. Treasury were carefully monitoring currency markets, suggesting greater concern in Washington and the potential for dollar-buying intervention. [
]The Fed rarely comments on the dollar because currency policy is up to the Treasury.
"It was extraordinary for the Fed to make a specific comment on the dollar, even in the context of inflationary risks," said Toshihiko Sakai, a manager of forex trading at Mitsubishi UFJ Trust Bank.
The dollar's tumble to record lows this year, driven by the Fed's aggressive rate cuts, has caused a vicious circle by adding fuel to the surge in oil and commodity prices and stoking inflation pressures around the world.
Analysts said Bernanke's unexpected reference to the weaker dollar could put a floor under the U.S. currency, but it may also tempt some investors to see if officials in Washington will back their words with action.
The Fed chief's comments also suggested the central bank is unlikely to cut interest rates further from 2 percent, and investors are looking for the next move to be a rate increase later in the year.
Masafumi Yamamoto, head of FX strategy for Japan at Royal Bank of Scotland, said the key message from Bernanke's speech to other central bankers in Spain is that the Fed's focus has shifted to containing inflation fears.
"From here, the next policy move will be a rate hike, not a cut. But it does not mean an immediate action by the Fed," Yamamoto said.
While U.S. Treasury Secretary Henry Paulson has repeatedly said a stronger dollar in is the country's interests, those words have largely fallen on deaf ears because Treasury secretaries have stuck to that refrain even as the U.S. currency slid.
But Bernanke struck a chord, especially by saying the U.S. central bank and Treasury were watching currency markets in what appeared to be in a reference to the most recent statement by Group of Seven financial leaders.
The G7 caught investors off guard in April by saying officials were monitoring exchange markets closely and will cooperate as appropriate, which was seen as a show of support for the dollar. [
]The dollar edged up to 105.15 yen <JPY=> from 105.07 yen in late U.S. trade after having moved back near a three-month high struck last week.
The euro barely budged at $1.5446 <EUR=> after having slid as low as $1.5410, tumbling 1.4 percent from Tuesday's peak. The single currency has retreated from the all-time peak of $1.6020 reached in April in the weeks following the G7 statement.
The dollar's trade-weighted index -- a gauge of its performance against six major currencies -- was flat at 73.325 <.DXY> after surging as much as 1.3 percent from Tuesday's lows. The dollar index has clawed back 3.7 percent from a record low hit in March.
The Australian dollar edged up 0.4 percent to $0.9563 after data showing Australia's economy expanded at a robust 3.6 percent annual rate in the first quarter, keeping alive expectations for higher interest rates. [
]Analysts were abuzz over Bernanke's remarks, which overshadowed the latest worries about the U.S. financial sector after reports Lehman Brothers <LEH.N> may need to raise capital.
"We take this as a meaningful shift in rhetoric," said currency strategists at Morgan Stanley in a note to clients.
"The Fed would not have made these comments without the support of the Treasury, given that the Treasury has the responsibility for exchange rate policy. In that regard, we can view this as a coordinated signal from U.S. monetary authorities," they said.
But Morgan Stanley said the risk of dollar-buying intervention was low for the time being, though it would be possible with all the G7 powers seeming to be more coordinated in their views on the dangers of a sliding U.S. currency.
Some analysts said Bernanke's comments will reverberate in markets for a while and showed that the United States no longer had a policy of "benign neglect" on the dollar, tolerating its weakness as long as it helps the economy through export growth. (Additional reporting by Satomi Noguchi)
