TOKYO, Sept 24 (Reuters) - The dollar edged down against the euro on Wednesday on uncertainty about the effectiveness of the U.S. government's proposed $700 billion bailout plan to tackle the financial crisis.
But the U.S. currency erased earlier losses and gained against the yen after news of Warren Buffett's Berkshire Hathaway Inc investing $5 billion in Goldman Sachs Group Inc <GS.N> sent U.S. equity futures shooting up in Asian trade. [
]"At the end of the day the dollar still remains in range. The main focus is on whether the U.S. Congress will approve the rescue plan within the week, and whether the plan functions as hoped if passed," said Tomoko Fujii, head of economics and strategy for Japan at Bank of America.
The greenback, amid volatile swings, has retreated against the euro in the past week or so since trouble in the U.S financial sector progressed from bad to worse, highlighted by last week's collapse of Lehman Brothers <LEHMQ.PK> and the $85 billion rescue of American International Group Inc <AIG.N>.
The financial crisis, stemming from the subprime debacle, has been dubbed America's worst since the Great Depression with still-standing Wall Street investment banks Morgan Stanley and Goldman Sachs receiving approval this week to become commercial banks.
The U.S. government's proposed rescue plan has failed to stem the dollar's slide, as uncertainty due to the plan's lack of details has fanned doubts about its effectiveness.
The euro advanced 0.1 percent to $1.4658 <EUR=> after a low of $1.4636. The dollar rose 0.3 percent to 105.90 yen <JPY=>, after dropping to around 105.35 yen earlier in the day.
The Goldman news sent S&P futures <SPc1> jumping as much as 23 points, and dragged the yen lower, stemming some of the inflow that the Japanese currency had enjoyed the previous day when U.S. stocks slumped on fear that congressional wrangling could delay the plan to rescue the financial sector.
Asian equity markets were jittery but erased much of their earlier losses, giving a boost to the dollar against the yen in the late afternoon trade.
The Nikkei stock average <
> ended up 0.2 percent, recovering from an earlier 1.5 percent drop."As it will take more time for the bailout plan to be enacted, the chances for the dollar and U.S. stocks to fall will increase," said a sales trader at a Japanese trust bank in a note to clients.
FOGGY DOLLAR OUTLOOK
Market watchers said longer-term prospects for the dollar remain foggy as questions linger over the U.S. bailout plan, limiting confidence over its positive impact on the financial sector.
Eyes are on August U.S. existing home sales figures slated for release on Wednesday, with analysts warning that the dollar could feel the heat if the numbers are discouraging.
"Expectations are for a decline in existing home sales. The widely held view is that the U.S. economy will not be able to gain a toehold towards recovery until the housing market slump comes to an end," said Fujii at Bank of America.
Market players will also be watching German September Ifo business confidence data to be released on Wednesday for further hints of economic weakness in the euro zone after factory data released the previous day showed euro-zone manufacturing activity contracted at its fastest rate in nearly seven years.
