Side bit of amusement:
A big problem with this bank failure is that most of the deposits were commercial, rather than personal.
In the US, bank deposits are guaranteed up to $250 k USD per depositor (joint account), but the commercial accounts were much, much larger.
Many companies have been caught short, and will have difficulty making payroll while their accounts are frozen.
That's not funny, but the US newspapers discussed the related closure of this bank in the UK, and reported the legal limit there as "$204,544", a rather precise value, which I assume is really 170 k GBP (for a joint account)?
This reminds me of when banks were robbed the old-fashioned way: an American newspaper would report a robbery in UK as being "$2,350,000", because the UK police had reported "about a million pounds".
