TOKYO, June 9 (Reuters) - The dollar rose against the yen on Monday, rebounding from a sharp fall late last week when data showing an unexpectedly big jump in the U.S. jobless rate revived fears of a deeper and more prolonged economic downturn.
The euro also climbed to a five-month high against the yen as investors shifted their focus to the euro zone's widening interest rate advantage compared with Japan, helping to lift the dollar versus the yen.
Traders said the earlier drop in the euro against the yen only invited traders to chase the euro higher after European Central Bank President Jean-Claude Trichet signalled last week a possible July rate hike to 4.25 percent next month to quell inflation pressures.
With Japan's Nikkei stock average still in sight of a five-month high, investors felt encouraged to return to risky carry trades, helping push up higher-yielding currencies such as the Australian dollar.
The Nikkei <
> dropped 2 percent, but losses were limited compared with the 3 percent slide on Wall Street.Little prospect is seen of Japanese rates rising in the immediate future from 0.5 percent, the lowest among industrial nations.
In carry trades, the low-yielding yen is borrowed to fund investment in higher-yielding currencies and assets. But such trades are vulnerable to falling share prices, which erode investors' tolerance for risk and typically prompt buying back of the yen.
"The euro seems to have taken centre stage for now, with a lot of talk favouring the euro against the yen," said a senior currency option trader at a big Japanese bank.
The dollar rose 0.4 percent from late Friday New York trade to 105.31 yen <JPY=>, rebounding nearly a full yen from the day's low of 104.40 yen hit on trading platform EBS.
Earlier in the session, traders rushed to cut dollar-long positions that had pushed the U.S currency to a three-month high above 106 yen last week, analysts said.
The euro climbed 0.3 percent to 166.07 yen <EURJPY=R> and reached a peak of 166.39 yen, the highest since late December, recovering sharply from an early low of 164.97 yen.
Against the dollar, the euro was little changed at $1.5780 <EUR=> after edging up to $1.5800 on EBS.
News on Friday of the biggest jump in the U.S. unemployment rate in 22 years, to 5.5 percent in May, dented expectations the Federal Reserve will hike interest rates before the year is out.
"The payrolls report last week made market players have second thoughts about the recent optimistic outlook for the U.S. economy, hurting the dollar," said Shuichi Kanehira, a senior trader at Mizuho Corporate Bank.
But he said market players would look to comments by Fed Chairman Ben Bernanke later on Monday to see if he repeats his rare attempt last week to talk up the dollar by saying a weakening of the currency is adding to price pressures.
Oil prices <CLc1> fell on Monday, giving the dollar some respite after its tumble late last week. They had posted their biggest ever one-day surge on Friday, leaping more than $10 to a record high near $140 a barrel.
