TOKYO, Aug 22 (Reuters) - The dollar limped up on Friday, recovering a little after its biggest one-day drop in five months, but worries about the U.S. financial sector limited the greenback's rally.
The dollar's sharp slide the previous day was mostly due to market players being forced to unwind bets favouring the U.S. currency after having chased it to eight-month highs, traders said.
Through the first two weeks of the month, the dollar soared as investors dumped positions they had made betting the global economy would withstand the U.S. downturn and the credit crisis by selling the euro, the Australian dollar and commodities.
Clear signs that the euro zone and other major economies are losing steam have prompted investors to expect some central banks starting to cut interest rates to shore up growth, just as the Federal Reserve is expected to keep rates steady for a while.
"ECB rate cuts are not fully discounted in the market, so the euro has more downside risk," said Koji Fukaya, a senior currency strategist at Deutsche Bank in Tokyo.
"The medium-term trend is still positive for the dollar against the euro and other currencies."
Analysts said the dollar had been overdue for a reversal of those sharp gains, but it was still on the road to a medium-term recovery after a seven-year slide to record lows.
Persistent doubts about the health of Fannie Mae <FNM.N>, Freddie Mac <FRE.N> and investment bank Lehman Brothers <LEH.N> have reminded investors about the housing-related troubles still plaguing the United States. [
]But those financial sector fears were not having the same repercussions in financial markets as they did earlier in the year, traders said.
Later in the day, Fed Chairman Ben Bernanke will speak on financial stability at the Kansas City Fed's annual symposium in Jackson Hole, Wyoming. [
]The dollar climbed 0.5 percent from late U.S. trade to 108.95 yen <JPY=>, pulling up from a low of 108.13 yen hit the previous day but off the seven-month peak of 110.67 yen hit this month.
Despite a brief surge the previous day, analysts said the Japanese currency would likely struggle as stalled economy meant the Bank of Japan was unlikely to raise interest rates from their low 0.5 percent.
"Investors don't see any factor solid enough to support yen buying beyond 108 a dollar," said Hideki Amikura, deputy general manager of forex trading at Nomura Trust and Banking.
The euro dipped 0.2 percent to $1.4880 <EUR=>, recovering from a six-month low of $1.4630 struck this week. Against the yen, the single currency rose 0.3 percent to 162.08 yen <EURJPY=R> after hitting a three-month low of 160.19 yen on Thursday.
The dollar index, a gauge of its performance against a basket of six major currencies, edged up 0.2 percent to 76.191 <.DXY> after falling 1.2 percent on Thursday -- the biggest one-day drop since March, when the index slumped to an all-time low.
"We continue to view recent gains in the U.S. dollar as sustainable," UBS currency strategists said in a note to clients, noting that more investors believe U.S. house prices should bottom out sometime next year.
The national slide in U.S. property prices has been at the root of the U.S. and global economic woes, leading to billions of dollars of write-downs on mortgage securities that have hobbled the global financial system.
The moves in the dollar and commodities remain closely linked and have been reinforcing each other.
Oil prices were holding above $121 a barrel <CLc1> after a $5 spike the previous day, partly on worries about escalating tensions between Russia and the United States. Gold slipped to near $834 an ounce <XAU=> after surging nearly $27 on Thursday. (Additional reporting by Rika Otsuka; Editing by Rodney Joyce)
