Accounts, Deposits & Interest Accrual
CASA and term deposits, holds, and how interest accrues and capitalises—settings that quietly drive P&L and complaints.
Objectives
- ▸Differentiate current, savings, and term deposit behaviours
- ▸Explain holds, liens, and available vs ledger balance
- ▸Describe accrual vs posting of interest
- ▸Spot product parameters that cause customer complaints
Current accounts prioritise payments; savings accounts blend payments with interest; term deposits lock funds for yield. Each has status lifecycles (active, dormant, frozen, closed) that payment products must honour.
- Ledger balance vs available balance (holds for authorisations, liens, mandates).
- Nominee / joint holding modes affect who can act.
- Dormancy rules can block unexpected debits—plan reactivation UX.
