From the story here:
It’s all fun and good to speculate on the SNB equity price, but I am more interested in what the SNB’s behaviour means for the global markets going forward.
The real problem is that a Central Bank just monetized their balance sheet against another country’s equity market, and instead of getting punished for this reckless behaviour, the markets are celebrating the Swiss good fortune. And I ask you - have you ever seen Central Bankers not behave like a bunch of antelopes on the Serengeti? It is an amazingly disturbing precedent.
