This is a link to my 56th column on Quartz: “The Swiss are now at a negative interest rate due to the Russian ruble collapse.” I kept something closer to my working title as the title of this companion post, and as what I plan for the long-run title.

This column is in honor of all the amazing people I met at the Swiss National Bank.

Update December 19: Paul Krugman links to my column as a news source in his column “Switzerland and the Inflation Hawks.” The link is on the words “charging banks."
