SNB didn't just stood there. They intervened heavily in the forex market. They took on hundreds of billions of Euros to defend that floor. They actually need to sell these Euros now that the price is going back up, or at least convert to something else. SNB need to unwind their Euro reserves desperately. I think it was like 70% of their reserves were in Euros. LOL. Yeah, so they were buying the Euros like hotcakes to defend it. They almost ran out of ammo, but the Euro is going higher, so they must quickly sell Euros if you ask me.
