Bank on this
As far as I can recall, none of the recent stream of operational features involves an actual bug with a real financial service, mortgage, debit payment, savings account. The features seem to reside in the bulk move or access to large splurges of data. This points much more to data management than it does to financial execution.
I will reiterate my call to remove bulk data management from the banks. Allow them access still, but take care of storage in an operation that has consistently demonstrated its ability to handle this kind of stuff. Expertly. Without failure. Cheaply.
