a much larger securities market to market losses than almost any other bank as well as having underinsured depositors who weren't loyal and sticky and likely to run, that combination with silicon valley, led to their rapid downfall. then the question was who else is managing their interest rate so badly and market to market box so badly that they could have a similar run which they wouldn't be able to handle. essentially that is a risk that the chairman had been talking about in the previous months, it was understood and out there, but over that weekend when there was panic about what other banks might face that combination, regulators didn't do the right thing, systemic risk was uninsured depositors of other banks might look at the losses on their balance sheets and suddenly leave. haw
