Commonwealth Bank has launched a notice account for business customers, designed to combine higher interest rates with flexible notice periods. The Capital Growth Account will offer rates that are 75 to 150 basis points above at-call business deposit rates. Customers have the option of choosing notice periods of 48 hours or seven days. CBA said comparable accounts offered by competitors have notice periods of at least 31 days. Mike Vacy-Lyle, group executive of business banking at CBA, said in a statement: “Many businesses hold cash for lump sum payments for specific periods of time, especially to cover tax payments at the end of the financial year.  “Flexible notice accounts give business customers the ability to earn extra interest, like a term deposit, on these funds without the same restrictions on withdrawals.”
