The U.S. dollar gave up its early gains against its key counterparts in the New York session on Friday, after Federal Reserve Chair Jerome Powell reiterated that the central bank would act as appropriate to sustain the economic expansion.
Speaking at annual Economic Policy Symposium in Jackson Hole, Powell said that the economy is close to Fed goals of maximum employment and price stability.
"Our challenge now is to do what monetary policy can do to sustain the expansion so that the benefits of the strong jobs market extend to more of those still left behind, and so that inflation is centered firmly around 2 percent," he said.
"We are examining the monetary policy tools we have used both in calm times and in crisis, and we are asking whether we should expand our toolkit," he added.
The currency has been trading higher against its major counterparts in the previous session.
