Banks don't close accounts because of low balances.  Have you ever tried to close a bank account?  It's a pain in the arse.  They do everything they can to keep every account open.  Why?  Because the idiotic "financial supermarket" sales model gives incentives at the branch level to open (and keep open) every single possible account they can.  The personal bankers have quotas for how many of each type of account to open each month.  Closing an account goes directly against this. PS.  The article specifically said she had $34k in that account.
