G20 central bankers and finance ministers meet in Shanghai Friday and Saturday, and there has been persistent chatter of FX intervention.

The Wall Street Journal address the question, concluding that "if currency misalignment is similar to 1985, the tools for dealing with it are not"

And that's a no-no.

What we'll hear instead are calls for fiscal measures (to take the pressure off monetary policy and exchange rates)

Much more at the piece, which appears to be ungated.
