Most savings accounts have tiered interest rates that require customers to fulfil multiple requirements, from salary credits to minimum credit card spends. In contrast, the Cash+ projected return of 1.5% p.a. applies to all your funds, with no additional criteria you must fulfil.
Cash+ also provides daily accrual of returns, unlike traditional savings accounts. This means you get to keep whatever returns you accumulate when you invest in Cash+, no matter the duration.
Lastly, while Cash+ is invested in very low risk bond funds, it is not capital guaranteed.
