The Greg Becker of the article (SVB CEO & president) was in SF Fed board of directors until Friday [1]. The current risk officer worked at NY Fed [2]. Previous risk officer was director of Freddie Mac [3]. Yellen was the 11th President of the SF Fed [5] and the current president is her protégé [6].
They knew exactly what they were doing. The Fed looked the other way. They sold a lot of stock in the past month [7]. They are very well connected into the Fed and Treasury. I doubt anybody will get any kind of serious legal troubles.
