The dollar weakened after the Fed, the U.S. central bank, on Wednesday indicated a marked shift in sentiment even as it left its benchmark rate unchanged for now. Gold prices soared to near six-year highs.
“I do think that today’s move is due to yesterday’s Fed move," said James Ragan, director of wealth management research at D.A. Davidson.
"The Fed was certainly more dovish than they were earlier in the year and it seems pretty likely that they are going to cut the rate at the July meeting."

Focus also is turning to next week's G20 meeting for any developments between the United States and China regarding their trade war that has raised concerns about global growth.
“There have been two drivers of the market gains this month: The expectations for the Fed to get more dovish; and optimism over the potential for some type of trade progress with China," Ragan said.
Government bond yields in the United States and Europe fell following the Fed's decision, with the U.S. 10-year note yield dropping below 2% for the first time in 2-1/2 years.
