TOKYO, Jan 18 (Reuters) - The dollar rebounded against the yen on Friday as Tokyo stocks erased earlier losses to edge higher, prompting investors to trim their bets that the Japanese currency will rise further due to an unwinding of carry trades.
The Nikkei share average <
> initially plunged as much as 3 percent to two-year lows, tracking sharp losses on Wall Street on Thursday on growing fears of a U.S. recession.A strong rebound in the benchmark shares helped investors to recover their risk tolerance, which had been hurt earlier in the session and driven the yen to a four-month high against the euro as investors rushed to exit risky carry trades.
In carry trades, market players use low-yielding currencies such as the yen to finance purchases of assets offering higher returns elsewhere. Those trades are vulnerable when stock markets fall and market volatility rises as they deteriorate investor risk appetite.
"The rebound of the stock market is the big factor for the yen's retreat this session," said Etsuko Yamashita, chief economist at Sumitomo Mitsui Bank.
"Also, market players are broadening their attention to weakness in the yen as well as the euro after selling the dollar sharply for some time."
The dollar was at 107.10 yen <JPY=>, up 0.25 percent from late New York trade on Thursday, rebounding from a day's low of 106.35 yen hit earlier in the session on electronic trading platform EBS. Demand from Japanese importers also helped the dollar to stay above a 2-1/2-year low of 105.92 yen hit on Wednesday.
The euro rose 0.2 percent to 156.75 yen <EURJPY=R> after falling to a four-month low of 155.69 yen earlier in the session.
POLICY ACTION IN FOCUS
In testimony before the House of Representatives' Budget Committee on Thursday, the Fed chief repeated a bleak assessment of the U.S. economy's health that he gave last week.
Investors took Bernanke's comments as a signal that the U.S. central bank is willing to cut the benchmark federal funds rate aggressively from the current 4.25 percent this month.
In the testimony, Bernanke also backed the idea that the struggling economy needs rescue while President George W. Bush urged a quick and temporary fiscal package, and that led some investors wonder about a possibility of an inter-meeting rate cut.
"Bernanke stressed that the fiscal stimulus measure needs to be designed to kick in quickly. I took his words that the Fed may also take action quickly to restore market confidence," said a senior portfolio manager at a Japanese trust bank.
The manager said he thinks the U.S. stocks could rebound temporarily if the White House and the Fed move together to announce policy actions, and help sentiment for the dollar.
Interest rate futures had already fully priced in a half-percentage point cut from the Fed at its regular policy meeting on Jan. 29-30, and saw a 50-50 chance of an even broader 75 basis point cut.
The euro was steady on the day at $1.4640 <EUR=>, off a two-week low of $1.4589 hit the previous session.
The euro tumbled this week after European Central Bank Governing Council member Yves Mersch told Bloomberg News on Wednesday he did not rule out a downward revision of euro zone growth forecasts for 2008, fuelling fears that U.S. economic weakness may be spreading to Europe.
"Mersch's comments continue to cast a shadow over the euro as the possibility of an ECB rate cut was not priced in by the market before the remarks," said a trader at a big Japanese bank.
"It will take time for the currency to start rising again," he said. (Additional reporting by Rika Otsuka)
