* Fed's Bullard fans doubts over December Fed rate hike
* Euro hits more than 2-1/2-yr high of $1.1868
* Commodity-linked currencies on backfoot on trade concerns
NEW YORK, Aug 2 (Reuters) - The U.S. dollar hit its lowest level against the euro in more than 2-1/2 years on Wednesday on doubts about another Federal Reserve interest rate increase this year and expectations for European Central Bank hawkishness.
The euro hit $1.1868, its highest level against the dollar since January 2015. In contrast to the political risks and monetary policy uncertainty that have plagued the dollar, the common currency has drawn support from expectations that the ECB would eventually begin phasing out its easy policy.
St. Louis Federal Reserve President James Bullard said he is opposed to further U.S. interest rate increases by the central bank and warned that more hikes could hinder achievement of the Fed's 2-percent domestic inflation goal, Market News International reported on Wednesday.
Bullard's comments reinforced skepticism surrounding another Fed rate increase this year, analysts said. Expectations for another Fed rate hike in December last stood at about 48 percent, according to CME Group's FedWatch tool.
"The market has reached a position where they think Fed hikes are going to be limited," said Jason Leinwand, founder and chief executive of FirstLine FX in Randolph, New Jersey. "Bullards comments would be more of a confirmation" of that view, he said.
While traders awaited Friday's July U.S. non-farm payrolls report, euro zone economic data has encouraged the view that the ECB is on a path toward tightening its monetary policy, which is considered a favorable scenario for the euro.
"Euro zone data just has constantly validated the optimistic outlook of the European Central Bank," said Kathy Lien, managing director of FX strategy at BK Asset Management in New York.
The dollar index, which measures the greenback against a basket of six major rivals, was last down 0.2 percent at 92.857 . The dollar gained slightly against the yen and was last at 110.46 yen, hovering above a more than six-week low touched Tuesday of 109.91 yen.
Fears of a trade spat between China and the United States saw the U.S. currency score some early gains against its commodity-linked rivals such as the New Zealand and the Canadian dollar.
The dollar was last up 0.4 percent against the Canadian dollar at C$1.2585 after touching a 1-1/2-week high of C$1.2591 . The New Zealand dollar touched a one-week low against the greenback of $0.7411.
Uncertainty over U.S. relations with Venezuela also caused commodity-linked currencies to dip against the greenback, Leinwand of FirstLine FX said.
