NEW YORK, March 3 (Reuters) - The dollar rose against the yen and euro on Tuesday as Federal Reserve Chairman Ben Bernanke called for bold government action to pull the economy out of recession, even if it means a surge in federal debt.
Bernanke's remarks to Congress heartened some investors who are betting that proactive measures to fight the crisis will help the United States become the first major economy to recover. For details see, [
]A report showing pending U.S. home sales falling to the lowest level since the data series began in 2001 also dulled risk appetite, causing Wall Street to surrender earlier gains and prompting safe-haven flows into the dollar. [
]."The pending home sales, which were worse than expected, did help the dollar, as it just heightens the downturn and increases the market's risk aversion," said Omer Esiner, senior market analyst at Reusch International in Washington.
"Bernanke's comments, on the other hand, are positive for the dollar in the short term because they suggest the government is doing all it can to get us out of this crisis," he said. But he added that rising government debt will hurt the dollar in the long run.
The euro fell 0.4 percent to $1.2539 <EUR=> after earlier rising as high as $1.2677. The dollar rose 1 percent to 98.20 yen <JPY=> as worries about Japan's economy continued to weigh on the Japanese currency.
Sterling fell 0.2 percent to $1.4014 <GBP=>, reversing earlier gains that lifted it to $1.4157.
Wall Street stocks initially rose on Tuesday, reversing some of the prior day's slide to levels last seen in 1997, but they fell back into negative territory after Bernanke's remarks and the U.S. housing data.
"It's really a simple equation right now: if equities go down, buy the dollar; if they go up, buy other currencies," said Shaun Osborne, senior currency strategist at TD Securities in Toronto.
Analysts said the market was also waiting to see if U.S. Treasury Secretary Timothy Geithner sheds new light on plans to shore up the financial system when he speaks to Congress later on Tuesday.
CENTRAL BANKS IN FOCUS
The euro also suffered from expectations of an imminent interest rate cut and worries about euro zone bank exposure to struggling Eastern European economies.
The European Central Bank is seen cutting rates by half a percentage point to an all-time low of 1.5 percent later this week, and on Tuesday, ECB council member Christian Noyer said policy-makers were considering all options, including unconventional monetary policy. [
]The Australian dollar remained the top performer after the central bank left interest rates at 3.25 percent, saying fiscal stimulus would keep a deeper recession at bay.
But it trimmed some of its early gains and was last up 1.4 percent at $0.6382 <AUD=> after hitting $0.6462 previously.
Other central banks were not as sanguine as Australia's. The U.S. dollar rose 0.4 percent against its Canadian counterpart to C$1.2950 <CAD=> after the Bank of Canada cut rates to a record low and said it may turn to quantitative easing.
The Bank of England is also seen bringing borrowing costs to a record low of 0.5 percent with its own half-point cut, and markets are on alert for the possible roll-out of alternative monetary policy measures. [
