Similar feature that Interactive Brokers (IBKR) have implemented into their brokerage accounts - uninvested money sitting in Pearler AU Cash / Automatic Investing accounts has the ability to earn interest for users each month.
This feature could give users more confidence to setup an automatic deposit each week without the fear of missing out on interest generated within a bank account. Interest amounts earned each month could appear in the “Transactions” tab and would just be added to the respective cash account.
