How about that to focus the mind.

IMFThe question is whether they can come up with some form of words at the IMF meetings over the weekend to calm the markets, to show that they are determined to address the imbalances that underlie the tensions over currencies.

Foreign exchange intervention by the Chinese to keep the yuan low is, after all, only part of the story.  The bigger problems are the uneven pace of global economic growth, the weakness of the U.S. economy that is fuelling the dollar’s decline, and the export-oriented policies of many other countries.
