CBS-1 Retail Deposit & Account Services

Mapping interconnections and interdependencies is a critical step in strengthening operational resilience for financial institutions.

For a retail bank, the ability to deliver Retail Deposit & Account Services depends on a complex network of people, processes, technology platforms, and third-party service providers working seamlessly together.

Any disruption to these supporting components can affect the bank’s ability to provide essential services, including account opening, deposits, withdrawals, transfers, and customer notifications.

Therefore, identifying and documenting these dependencies enables the organisation to understand how failures may propagate across systems and business processes.

For Clarien Bank, the Critical Business Service CBS-1 Retail Deposit & Account Services supports the fundamental banking relationship between the institution and its customers.

The dependency mapping presented in this chapter highlights how each Sub-CBS relies on supporting resources and external parties.

This mapping aligns with operational resilience principles described in the BCM Institute guidance on mapping interconnections and interdependencies, allowing the bank to better manage risks, plan recovery strategies, and ensure continuity of essential banking services during disruptions.
