The dollar extended declines despite Treasury Secretary Steve Mnuchin's attempts to clarify comments he made on Wednesday, Jan. 24, to reporters in Davos as he arrived at the World Economic Forum.

"I thought my comment on the dollar was actually quite clear (Wednesday)," Mnuchin said. "I thought it was actually balanced and consistent with what I've said before, which is, we are not concerned with where the dollar is in the short-term. And it's a very very liquid market."
