In a dramatic move, the SNB has decided to put a floor on the price of the CHF vs Euro, a floor at 1.20 CHF per Euro. This is a defacto peg to the Euro as the Swiss franc is unlikely to decline and this resulted in a massive 8% move in the Swiss Franc / Euro exchange rate a massive move (probably unheard of) in the currency markets.

Another battle has been fought in the currency war and the Swiss Franc is no longer a safe heaven. There remains the Yen (but I wonder why) and possibly the Singapore dollar (SGD) which appreciated around 6% against the USD since the beginning of the year. Of course, there is still gold and silver which should remain the real safe heavens.
