One spying scandal, you can survive. Two, even. But three? Well, that starts to look like carelessness, either in setting up a far-reaching global surveillance apparatus to make sure that no suspect employees are screwing you over, or in not knowing that such an apparatus had been set up under your nose by your closest lieutenant. And that sort of carelessness is both very detrimental to one’s reputation, and also very unSwiss. And so, no matter how good a job Tidjane Thiam did turning Credit Suisse around (a fairly decent one, it has to be said) or how many major investors wanted a different human sacrifice, this was probably inevitable (even if we didn’t realize that earlier this week).
