SNB intervention definitely a possibility
Firstly let’s state the perfectly bleedin’ obvious! Do not take any positions based on central bank’s fools errands!
Ok, that’s out of the way. SNB chief Jordan said the following in a weekend interview with the Neue Zuercher Zeitung:
We are still monitoring the FX markets, and will intervene if necessary
When and where they will intervene is another matter. I cannot imagine that they would be so stupid again as to try and lift the market by force, but they will almost certainly step in, especially in USD/CHF, if prices start falling too far and too fast.
