Swiss central bank unusually transparent about FX action

Swiss National Bank gave rare confirmation that it had intervened in the currency market to weaken the Swiss franc in the wake of Britain's vote to leave the European Union, as reported by Reuters:

"Following the United Kingdom's vote to leave the European Union, the Swiss franc came under upward pressure," the SNB said in a statement. "The Swiss National Bank has intervened in the foreign exchange market to stabilise the situation and will remain active in that market."

According to Reuters, the SNB normally declines to comment on whether or not it has been active in the currency market.

This unusual transparency seemed to serve as a sort of statement on its own, to demonstrate to markets along with other major central banks that the SNB is alive and kicking and performing business as usual.
