What does artificially pegging your currency through 4+ years of central bank manipulation get you?
In our lifetime there has never been a day like today. Years from now when a currency moves 300 pips (which used to be a big move) traders will be like "remember when the Franc moved over 2,000 pips in just a few hours back in 2015?". Its truly a historic day, and not for good reasons... at least as far as I am concerned.
The Swiss decided to wave the white flag today and end years of artificial price fixing of their currency. For us mere mortals manipulating the price of something would likely land us in jail, for a central bank its just another day of lining their pockets. Heck three years ago the head of the Swiss Bank's wife was front running all the currency manipulation. Today's massive move, historic move, once in a lifetime move.... what are the odds some Swiss Bankers wife wasn't front running it?
