NEW YORK, June 18 (Reuters) - The dollar recovered some recent losses on Wednesday but gains were capped as investors scaled back expectations that the Federal Reserve will raise interest rates in August after conflicting U.S. economic data.
Traders have also pared bets that the European Central Bank will tighten policy with a series of rate hikes, giving the dollar some support following two straight days of losses versus the euro.
Analysts said trading conditions were expected to become more volatile, tracking frequent policy-maker nuances on the interest rate outlook in the euro area and United States.
"There is a little bit of a dollar bid, but what we see is the dollar continuing to trade sideways within well worn ranges," said Michael Woolfolk, currency strategist at Bank of New York Mellon in New York.
"Officials from both Europe and the U.S. have been trying to downplay expectations of a series of rate hikes by the Fed and the ECB before year-end."
The New York Board of Trade's dollar index, which tracks the dollar's performance against a basket of six currencies, rose as high as 73.774 <.DXY> in overnight trade. It was last up 0.2 percent at 73.668 in New York morning trade.
The euro was down 0.2 percent at $1.5481 <EUR=> after earlier slipping to $1.5462. The dollar rose 0.1 percent to 108.08 yen <JPY=>.
RATE HIKE CHANCES TRIMMED
With no major economic data due for release during the New York trading session, traders will monitor comments by Janet Yellen, the San Francisco Federal Reserve president, at 11:45 a.m. (1545 GMT) and the weekly national petroleum report.
U.S. short-term interest rate futures are pricing in a 50 percent chance of a 25 basis points Fed rate increase in August, down from 90 percent earlier in the week.
The U.S. central bank is widely expected to keep its benchmark fed funds rate target at 2 percent next week, having slashed it by 3.25 basis points since mid-September.
"There is no one who believes we are at a neutral policy stance now on behalf of the Fed. We have extraordinary monetary accommodation which at some point needs to be removed," said Woolfolk.
A tightening in monetary policy will help the dollar regain some of its appeal to investors seeking higher returns.
Expectations of a series of rates hikes from the ECB have also been scaled back in recent days, but a move to 4.25 percent in July is still widely expected.
"What we're really having to contend with at the moment is how central bank rhetoric and economic data is challenging market expectations for monetary tightening by the end of the year in the U.S. and euro area," said Kamal Sharma, G10 strategist at JP Morgan in London.
"Over the near term, we think euro/dollar is likely to be a tug of war between competing central bank rhetoric."
Investors got more evidence of the U.S. economy's poor health from FedEX Corp <FDX.N>, which reported a quarterly loss and gave a dismal outlook for 2009.
Sterling remained on the back foot against the dollar, dipping 0.1 percent to $1.9525 <GBP=> with little reaction to minutes from the Bank of England's last policy meeting that showed an 8-to-1 vote in favor of keeping British borrowing costs on hold at 5 percent.
The market has been speculating on the possibility of a rate hike from the British central bank to tame accelerating consumer price inflation, which hit an annual 3.3 percent, above the bank's 2.0 percent target and its highest since the Labour government took power in 1997 [
