These are strange and unnerving times in global financial markets, and if Thursday’s jaw-dropping move in the Swiss currency didn’t prove it, nothing will.
It is not every day that the currency of an advanced, economically important country rises by double-digit percentages against the currencies of other such countries within mere hours. But that is what happened to the Swiss franc on Thursday. It is up 18 percent against the euro as of Thursday morning, and at one point was up 39 percent. Currency strategists were searching for any analogue in modern history for a similarly abrupt move in major Western currency and coming up empty.
The Swiss move offers interesting lessons about the oddly precarious state of the global economy, but first it’s worth working through what exactly the Swiss National Bank has done.
