Here is a link to my 59th column on Quartz, “Swiss pioneers! What unpegging the franc from the euro means for the US dollar.”

Update, January 19, 2015: Denmark lowered its interest on reserves from -.05% to -.2%. Danmarks Nationalbank has viewed its currency peg with the euro as the heart of its monetary policy for many decades.

Thanks to Mark Fontana for letting me know in real time about the Swiss National Bank’s and Danmarks Nationalbank’s actions.
