The Swiss banking market is to an uncomfortably large degree an opaque vault for unsavory money, everyone knows that. Just how unsavory? That is the question that the SZ's now-infamous investigative reporting team (Panama Papers, Paradise Papers, Ibizagate, ...) tried to answer using a leak of client data from Credit Suisse. The result? Warlords, corrupt politicians, and other undesirables are welcome clients. Apparently, the respective compliance departments believe KYC and AML are fast-food chains. Anything else would indicate malicious intent or smug indifference.
Unfortunately, the book itself, while important, appears rushed, and the authors even state as much. The book lists a small number of high-profile cases and their connection to CS. Some are already water under the bridge while others open up to serious allegations yet to be investigated. I would have preferred a more conclusive post-mortem a few months down the road. Unfortunately, recent geopolitical events have all but drowned out the press coverage on this undoubtedly important investigation. It appears the devil does indeed look after his own.
