The U.S. dollar hit a more than two-week high against the euro on Tuesday on continued belief that the Federal Reserve would hike rates this year while the European Central Bank could ease further.

The euro hit $1.11130, its lowest against the greenback since Sept. 4, following Fed officials' recent comments indicating that the U.S. central bank was still on track to raise interest rates this year for the first time since 2006.

Analysts said traders expect the ECB, meanwhile, to ease policy further. One- and three-month euro/dollar risk reversals , which measure demand for options on a currency falling or rising, show their biggest bias in over seven weeks for a weaker euro.

"The looking forward to December as pretty much a launch date," said Boris Schlossberg, managing director at BK Asset Management in New York, in reference to the Fed's first rate hike.

Rate hikes are expected to boost the dollar by driving investment flows into the United States.

Are we on the cusp of a currency war?

The dollar slipped against the Japanese yen, meanwhile, on concerns about global growth. Analysts said traders digested the Fed's Sept. 17 policy statement and comments from Fed Chair Janet Yellen regarding worries about the global economy, which in turn helped the safe-haven yen gain while riskier emerging market currencies fell.

The U.S. dollar hit a record high against Brazil's real of 4.0667 reais, and hit a nearly two-week high against the Mexican peso of 16.9 pesos, before trading at 16.89.

"You've got the Fed warning about global weakness, and then...some (Fed) board members said we need to hike rates," said Joseph Trevisani, chief market strategist at WorldWideMarkets in Woodcliff Lake, New Jersey. "Both things are bad for emerging markets and for the risk play."

ECB President Mario Draghi will speak on Wednesday, while Fed Chair Yellen will speak on Thursday. Analysts said expectations that Draghi would hint at more stimulus kept the euro lower against the dollar.

The euro was last down 0.53 percent against the dollar at $1.1126. The dollar was last down 0.32 percent against the yen at 120.11 yen. The dollar was last up 0.32 percent against the Swiss franc at 0.9751 franc.
