Powell, who took over from former Fed chief Janet Yellen in early February, said the central bank was staying on a path of gradual rate increases but needed to be on guard against inflation. "We are trying to take the middle ground here," Powell said in a press conference after the end of the policy meeting, adding that there were no signs the economy was on the cusp of accelerating inflation.
The rate hike was widely expected. All 104 economists polled by Reuters from March 5-13 said the Fed would increase borrowing costs this week.
US stocks rose after the policy statement before paring gains to close lower. US Treasury yields fell and then recovered. "The guidance in terms of the future rate hikes is a touch more hawkish than originally expected. 2019 looks like we're going to get a faster pace of rate hikes," said Matt Miskin, market strategist at John Hancock Investments. "This a new Fed chairman starting with a bit of a hawkish tone as he takes leadership."
CONFIDENCE IN THE ECONOMY
The rate hike was the latest step away from years of stimulating the world's largest economy in the wake of the 2007-2009 financial crisis and recession. The Fed tightened policy three times last year.
The combination of $1.8 trillion in expected fiscal stimulus from the Trump administration and recent hints of price and wage pressures had prompted some Fed officials to speculate more Americans could be drawn into an already tight labor market.
Some even worried inflation could rise well above the Fed's target if the economy got too hot.
Policymakers were largely split on Wednesday as to whether a total of three or four rate hikes would be needed this year. They predicted rates would rise three times next year and two times in 2020, a further indication of their view that the economy is on solid footing.
"The Fed seems to be gaining confidence," said Brian Coulton, an economist at Fitch Rating in London.
Fed policymakers projected U.S. economic growth of 2.7 percent in 2018, an increase from the 2.5 percent forecast in December, and also marked up growth for next year. The Fed's preferred measure of inflation was expected to end 2018 at 1.9 percent, unchanged from the previous forecast, but it is seen rising a bit above the target next year.
The U.S. unemployment rate by the end of 2018 is expected to edge down to 3.8 percent, indicating the Fed sees more room for the labor market to run. Fed officials predicted the longer-run rate would settle at 4.5 percent, slightly lower than the forecast from December.
