Is total assets a useful measure here? I would be more interested in a chart that showed budgetary shortfalls. It sounds like SVB is only short about 10% of total assets if I am remembering what I read earlier this morning.

No one really knows.

And banks usually aren't crazy amounts short. But they're short enough to got under.

lehman brothers had total assets of $639B when it filed for bankruptcy on September 15, 2008. adjusted for inflation that's ~$800B.

Lehman was an investment bank — they didn't take deposits. Wikipedia describes them as a "financial services firm".
