I have no inside information on SVB or their depositors, and no prior experience with managing a bank run. (I also have no exposure to SVB, nor do I have any stock market positions that may be affected by it.)
If you want my motivation for discussing it all day: I’m curious, it’s an interesting and fast-moving puzzle that a lot of smart people are discussing. If you want my qualifications for offering so many specific assertions: I’ve read the primary sources and it just doesn’t seem like it would fix or prevent this the way other people assume it would. If in my enthusiasm I’ve oversold myself as an expert, I apologize unreservedly.
