CBS-1 Retail Deposit & Account Services

Introduction

Mapping dependencies for CBS-1 Retail Deposit and Account Services helps the Philippine National Bank (PNB) understand how the service is actually delivered end-to-end across people, processes, technology, infrastructure, and third parties.

The BCM Institute’s mapping guidance explains that interconnection and interdependency mapping should identify the links among people, processes, information, technology, facilities, and service providers that support each critical business service, so that weaknesses and points of disruption can be identified before an incident occurs.

BSP Circular No. 1203 takes the same direction by requiring BSFIs to identify critical operations, map interconnections and interdependencies, assess vulnerabilities, and use the results to inform tolerance-setting, risk management, and scenario testing.

For PNB, this is especially relevant because retail deposit services are delivered through a mix of branches, ATMs, passbook/ debit-based accounts, and PNB Digital channels.

PNB publicly indicates that customers can access deposit accounts through branch and ATM networks and can enrol eligible debit, passbook, checking, pensioner, and other accounts in PNB Digital, which means the retail deposit service depends on tightly connected front-office staff, core banking processes, digital authentication, transaction monitoring, settlement, and customer communications.

Recommended operational resilience dependency map for CBS-1 Retail Deposit and Account Services at the Philippine National Bank.

This is a practitioner-style mapping based on the BCM Institute's dependency-mapping method, the requirements of BSP Circular No. 1203, and PNB’s publicly visible retail banking delivery model.

Regulatory Requirements and Examples for a Philippine Bank

Under BSP Circular No. 1203, the board is expected to approve the identified critical operations, which then drive the next steps of setting disruption tolerances and mapping interconnections and interdependencies.

The circular also expects BSFIs to use the operational risk management function to identify vulnerabilities affecting critical operations and to keep the identification process dynamic as threats, weaknesses, and business conditions change.

For dependency mapping, the circular gives several practical expectations that are directly relevant to a retail deposit service such as this one. It says the mapping exercise should be harmonised with operational risk, third-party risk, business continuity, and ICT risk activities.

It also requires banks to assess the effect of change management on delivery of critical operations and on their interconnections and interdependencies, to conduct due diligence on third parties supporting critical operations, to ensure third-party arrangements explain how services will be maintained during disruption or exited safely, and to assess dependencies on public infrastructure such as telecommunications, transportation, and energy.

The BSP also highlights the importance of technology and cyber resilience in maintaining critical operations. It expects risk-based, integrated, multi-layer strategies to protect the confidentiality, integrity, and availability of the IT environment, and it expects ICT protection, detection, response, and recovery capabilities to be tested under severe but plausible scenarios.

The circular even gives examples of scenarios that banks are strongly encouraged to consider, including a major earthquake, a severe typhoon, a failure of a critical third-party provider, payment and settlement disturbances, and a coordinated cyberattack or ransomware event.

 

The dependency map for CBS-1 Retail Deposit and Account Services shows that the service is not delivered by a single department or system; it is sustained by a tightly linked operating chain across branch personnel, compliance controls, core banking platforms, digital channels, ATM and cash-access infrastructure, reconciliation routines, fraud monitoring, and recovery capabilities.

Using the BCM Institute approach, the real value of mapping lies in making those links visible so that PNB can identify where a single point of failure, weak handoff, vendor dependency, or infrastructure outage could interrupt service delivery.

For PNB, this chapter’s map should be treated as a working baseline for operational resilience implementation.

It can now be used to support the next required activities under BSP Circular No. 1203, namely, validating critical operation boundaries, confirming vulnerability points, setting tolerances for disruption, developing severe but plausible scenarios, and testing whether the bank can continue or restore deposit services within acceptable limits.

In practice, the stronger the dependency map, the stronger the bank’s ability to protect customers, maintain confidence, and recover its retail deposit services through disruption.
