Put your surplus cash to work

Do you want to earn interest on your surplus cash while still being able to respond quickly to business opportunities or financial obligations? Our Business Investment Account (BIA) lets you access your funds whenever you want.


  • The Business Investment Account (BIA) is a transfer account available in CAD and USD.
  • Only transfers can be carried out using this account, so a business current account4 in the same currency at National Bank is also required.
  • You can transfer funds via our Internet Banking Solutions, our automated telephone service5 or at the branch where you opened your account.
  • There are no fees for credit transfers (deposits) made to your account.
  • Three free debit transfers (withdrawals) are allowed per month. A fee is charged for each additional debit transfer.
