Geithner, Timothy

"No government, no central bank can be indifferent to changes in the value of its currency," Geithner said.

He said the dollar was important not just because of its effect on growth and inflation in the U.S. and elsewhere but also because of "the very important role" it plays in the international financial system.

Geithner added: "As a result, as you would expect, we pay very close attention to what happens in (foreign) exchange markets."
