TOKYO, Oct 1 (Reuters) - The dollar dipped against the euro on Wednesday a day after it surged on quarter-end deals and on hopes that U.S. lawmakers could still reach agreement to revive a $700 billion bank bailout plan to stem the credit crisis.
Light selling hurt the dollar as investors thought the previous day's rally was exaggerated, traders said.
Activity was light in Asia as markets in China, Singapore and many other parts of the region were closed for national holidays.
The dollar posted its biggest jump against the euro on Tuesday since the introduction of the single currency in 1999 as investors bet Washington would manage to salvage the package after its shock rejection by the House of Representatives on Monday.
"Investors have been reacting too strongly to the situation in Europe while being too optimistic about the United States," said Hideki Hayashi, chief economist at Shinko Securities.
Traders also said the previous day's hefty gains in the dollar were partly explained by a dollar shortage at some institutions before the end of the July-September quarter, repatriation of overseas assets by U.S. investors and dollar demand from hedge funds facing redemption.
"If people can't fund themselves through the money market or swaps, they have to go out and buy dollars. That's what we've descended into," said Gerrard Katz, head of North Asia currency trading at Standard Chartered in Hong Kong.
The euro edged up 0.1 percent from late U.S. trade to $1.4106 <EUR=>.
The dollar dipped 0.2 percent against the yen to 105.88 yen <JPY=>. The U.S. currency staged a sharp rebound on Tuesday from a four-month low of 103.50 yen hit in early trade.
Adding to a cautious feeling towards the dollar was a slide in U.S. stock futures <SPc1> during Asian trade.
The euro was down 0.1 percent at 149.38 yen <EURJPY=>.
On Tuesday, the euro plunged 2.4 percent against the dollar after news of another bank bailout in Europe worsened fears about widening fallout from the credit crisis.
Banks in Britain, Belgium, Russia, Iceland and the United States have been rescued by authorities this week, prompting huge cash injections into the global banking system by central banks in an attempt to relieve frozen money markets.
But interbank rates stayed high, showing banks are still scrambling for dollars even at the start of a new quarter.
Traders and analysts said the market's focal point remains whether Congress will be able to pass a package to buy toxic assets from struggling banks in an effort to revitalise strained lending markets.
U.S. House Republican leader John Boehner backs a revised financial rescue plan and believes Congress should pass it, his spokesman said on Tuesday. The revised plan includes increasing federal coverage of bank deposits to $250,000 from $100,000. [
]"While the dollar lacks clear direction, investors are likely to be moved between hope and despair by developments in Washington," said a senior trader at a Japanese brokerage.
The Bank of Japan's tankan quarterly survey showed on Wednesday that business sentiment has turned pessimistic for the first time in five years, a sign that a global slowdown and financial turmoil were taking a toll as the economy teeters on the brink of recession. [
