💡 Accountant's Note
The interest cost on customer deposits is the bank's primary funding expense. It is accrued monthly and settled on payment dates. The net interest margin (NIM) is the difference between interest income on loans and interest expense on deposits.
Practitioner & Systems Framework
💻 ERP Architecture
In SAP Bank Analyzer, deposit interest accrual is part of the same EOD/EOM batch as loan interest accrual but credits the interest payable account. In Oracle FLEXCUBE, the ACCINIT batch processes all CASA and TD accounts. The Finance team reconciles the total against the ALCO rate model each month.
⚠️ Audit Flags
Auditors test that rates applied to deposits match ALCO-approved schedules. Segmentation errors (e.g., applying wholesale rates to retail accounts) are flagged. IFRS 9 requires that deposit interest reflects the EIR including any premium paid to attract deposits.
📄 Required Documentation
Month-end deposit interest accrual report by product type, ALCO rate approval minutes, and reconciliation to the interest expense general ledger.
