NEW YORK, July 29 (Reuters) - The U.S. dollar hit fresh eight-month highs against the euro on Tuesday and advanced against the yen and Swiss franc on expectations for positive U.S. economic data and a potentially more hawkish tone from the Federal Reserve.
Analysts said the Fed, which is expected to cut its monthly bond-buying program by another $10 billion after its two-day meeting ends on Wednesday, may hint at an approaching hike in interest rates in light of U.S. labor market growth.
"The market is starting to get more comfortable with the idea that a shift in (the Fed's) tone is coming, and they're positioning for it," said Ian Gordon, FX strategist at Bank of America Merrill Lynch in New York.
He said, however, that Bank of America expects the central bank to maintain a dovish stance given Fed officials' emphasis on continued slack in the labor market. An eventual rate hike would boost the dollar by attracting investment flows into the United States, analysts have said.
Analysts said expectations for positive U.S. second-quarter gross domestic product growth and July nonfarm payrolls data supported the dollar. The GDP data, due Wednesday, is expected to show a 3 percent advance after a 2.9 percent contraction in the first quarter, according to a Reuters poll of economists.
Economists expect the Labor Department's nonfarm payrolls report to show U.S. employers added 233,000 jobs in July, down from 288,000 in June but still showing momentum in the U.S. labor market.
Conference Board data on Tuesday showed its index of U.S. consumer confidence rose to 90.9 in July, beating economists' expectations of 85.3 and marking its highest level since October 2007. That helped underpin the dollar's strength against major currencies.
"The overall picture is of a continuing U.S. recovery, and the number this morning is in line with that," said Aroop Chatterjee, currency strategist at Barclays in New York.
Analysts also said new European sanctions against Moscow, which the European Union agreed to impose on Tuesday, weighed on the euro given the potentially negative impact on trade ties between Russia and Europe.
The euro was last down 0.22 percent against the U.S. dollar at $1.3410, slightly above a fresh eight-month low of $1.3402.
The dollar was last up 0.27 percent against the Japanese yen at 102.12, just under an earlier three-week high of 102.15.
The dollar was up 0.32 percent against the Swiss franc to trade at 0.9069 franc, just below an earlier five-month high of 0.9074 franc.
The U.S. dollar index, which measures the dollar against a basket of six major currencies, was last up 0.22 percent at 81.202.
The benchmark 10-year U.S. Treasury note yield fell to 2.46 percent, from 2.49 percent late Monday.
