What does the SNB know that the rest of us are just guessing at?

USDCHF and EURCHF ramped up in the past hour as we wait on ECB 8 Dec

A pre-emptive strike based on fact or just a case of "just in case" ? Either way I'm putting the SNB back in the dock as the countdown to the ECB announcement and presser gets ever closer.

USDHCF has ramped up to 1.0078 from 1.0045 and EURCHF to 1.0881 which is helping to put a bid under EUR pairs generally.

So are the SNB looking for some bearish moves out of the ECB or, just like the rest of us, second-guessing?

We'll know soon enough.
