The Canadian dollar has been remarkably stable against the Swiss franc since the beginning of 2015, which was incidentally the time at which the Swiss National Bank broke the peg between the euro and the franc, causing the franc to strengthen significantly overnight. The CAD/CHF currency pair has traded in the range of 0.68 to 0.80 since mid-January of 2015.
