NEW YORK (Reuters) - The dollar added to gains against a basket of major currencies on Tuesday after Federal Reserve Chairman Jerome Powell told U.S. lawmakers the central bank would stick with gradual interest rate increases despite the added stimulus of tax cuts and government spending.
Powell pledged to "strike a balance" between the risk of an overheating economy and the need to keep growth on track. His congressional testimony was his first public appearance since being sworn in as chairman earlier this month.
Powell is scheduled to present his remarks to a U.S. House of Representatives committee at a hearing scheduled for 10 a.m. EST (1500 GMT), followed by questions from lawmakers.
Brad Bechtel, managing director FX at Jefferies, in New York, said Powell's comments were generally positive for the dollar.
"He is hawkish in the context of being very upbeat on the economy but willing to go at a moderate pace to normalize policy," Bechtel said.
The dollar index (DXY), which measures the greenback against a basket of six other major currencies, was up 0.26 percent at 90.089.
Some of the headwinds the U.S. economy faced in previous years have turned into tailwinds, Powell said, noting recent fiscal policy shifts and the global economic recovery.
"That's sort of a big statement if you think about it," said Bechtel.
"He's kind of dialed it up just a notch from where (Powell's predecessor, Janet) Yellen was," Bechtel said.
The Fed is expected to approve its first rate increase of 2018 at its next policy meeting in March, when it will also provide fresh economic projections and Powell will hold his first news conference. Fed policymakers anticipate three rate increases this year.
"From a 10,000-foot view, Powell's prepared remarks are common-sense," said Guy LeBas, chief fixed income strategist at Janney Montgomery Scott in Philadelphia.
"It's more interesting to see that the market is interpreting the comments as somewhat hawkish, and that's more informative about the trading bias right now than about the Fed's actually likely policy path."
The dollar was up 0.19 percent against the Japanese yen
The euro (EUR=) was down 0.26 percent against the dollar at 1.2284.
Italians vote in a national election on Sunday, while the leading political parties in Germany will decide on a coalition deal that could secure Angela Merkel a fourth term as chancellor.
There was not a whole lot of fear in the market about the outcome of the Italian election, Bechtel said.
"There is a lot of folks looking at hedges but not a huge amount of activity in that space. Kind of an ambivalence toward the election this weekend, which is interesting," said Bechtel.
