BSB is an acronym for Bank State Branch number. This six-digit number represents your bank and the branch where your account is held. You will need this number when setting up automatic payments such as periodical payments or direct debits between BankSA and another party. You can find the BSB on the top right hand side of your account statement or in the "Account Information" section, next to the Account Number listing when you log onto Internet Banking. If you have a chequebook with your account, your account BSB is also printed on each cheque, in between the cheque number and the account number.

Buffer (Margin Lending)

Every investment has risks. Margin Lending is no exception. However, to help protect you from fluctuations in the share market that could result in a margin call the following buffers are currently 'built-in' to the value of your investment:

  • 5% for shares with a gearing ratio of more than 75%
  • 10% for shares with a gearing ratio of 75% or less
  • 10% for managed funds

It is expected that whilst you are in buffer you take action to bring your account back below the appropriate gearing ratio to help manage your risk of being in a margin call.
