I wont call the Swiss decision a currency war. Swiss decided for itself, that it wanted to float the Franc again. But we had a currency war at 16th December 2014 when Rubel dropped by nearly 40% on one day, and went up again next day. This was a currency war against Russia that failed. Russia had to push about US$100 billion on the market at that day, to win this currency war. The other side therefor was likely also a state owned player.
