SNB will do everything in their power to hold the floor. SNB's Jordan has insisted this from the get-go. I don't believe this can be compared to the Yen's failed intervention attempts or previous failed SNB intervention attempts. This floor, peg, intervention whatever you want to call it has been extremely expensive for the SNB. They'll commit billions to this and may be able to hold this floor strong for many months to come..We'll have to keep checking with the balance sheet and see where it's at every week or so.
Good luck trading out there.
