U.S. Treasury Secretary Jacob Lew has said Japan must stay within the bounds of an international agreement not to target exchange rates, after the dollar-yen broke through 100 and continued to extend gains on Friday.
Lew declined to criticize Japan and said he wouldn't comment on day-to-day moves in the yen, but he added that recent G20 meetings in Washington and Moscow had affirmed an international policy agreement over currency devaluation.

"The world has made clear that domestic tools that are designed to deal with domestic growth are within the bounds of what the international community thinks is appropriate and that policies that are targeted to affect exchange rates are not," Lew told CNBC's Steve Liesman in an interview in London.
