Central bankers lurch from 'whatever it takes' to 'whatever next'
By Mike Dolan
LONDON (Reuters) - The Swiss currency shock has raised an awkward question many investors have been fearful of asking - what if central banks become as unpredictable and fallible as they are powerful?
The Swiss National Bank's sudden decision to abandon its three-year-old cap on the franc - the "cornerstone" of its monetary policy just three days before - led to the biggest one-day move in major exchange rates in the post-1973 floating rates era.

The subsequent waves of cheap credit, currency fixes and "quantitative easing" drove down borrowing rates and erased volatility.
The demonstrations of central bank might culminated in ECB chief Mario Draghi's declaration in 2012 that he would do "whatever it takes" to save the euro. In the face of the power of the money printing press, speculation became pointless.
