Earlier quoted context omitted.
> The Swiss franc is currently pegged 1:1 with USD, having ditched Euro peg almost 5 years ago. It's not.
The Swiss central bank actively tries to maintain parity Use whatever word you want to quickly convey that thought to a broad population “Peg” also does that.
Over the last four years the EUR has moved in the range 1.06-1.20 CHF (a +/- 6.0% interval around the midpoint). The average rate is 1.117, the standard deviation 0.034 (3.1%).
Even though the exchange with the USD is slightly more stable in this case (it depends on the period and metric chosen) saying that it's pegged is an exaggeration.
By the way, the CHF was not pegged to the EUR either. There was a minimum rate set by the SNB at 1.20 but it floated as high as 1.26 in 2013.
