[OR] [PNB] [E3] [CBS] [1] [DP] Retail Deposit and Account Services

CBS-1 Retail Deposit & Account Services

For the Philippine National Bank (PNB), the delivery of Retail Deposit and Account Services (CBS-1) represents one of the most fundamental and customer-facing critical business services.

It encompasses the full lifecycle of a depositor relationship—from onboarding and account opening to ongoing servicing, transaction processing, and customer access across branch and digital channels.

In the context of operational resilience, this service is not merely a collection of banking activities but a continuous, integrated service chain that must remain available, secure, and reliable even during disruptions.

Aligned with the expectations set out in BSP Circular No. 1203, banks are required to move beyond high-level service identification and develop a granular understanding of the underlying processes that support each critical business service.

This requires decomposing CBS-1 into its detailed business processes (Sub-CBS), enabling the bank to identify vulnerabilities, map dependencies, and assess the resilience of each component.

By breaking down CBS-1 into its constituent processes, PNB lays the foundation for subsequent stages, including dependency mapping, resource mapping, impact tolerance setting, and scenario testing.

Purpose of the Chapter

The purpose of this chapter is to provide a structured and detailed breakdown of the end-to-end processes that constitute CBS-1 Retail Deposit and Account Services for PNB.

By presenting the Sub-CBS clearly and systematically, this chapter enables readers to understand how each process contributes to the overall delivery of the service and where potential disruptions may arise.

It pre-empts the reader by stating that operational resilience begins with process clarity—without a precise understanding of how services are delivered, it is not possible to assess resilience or design effective safeguards.

At the end of this chapter, the reader is expected to gain a comprehensive view of the operational building blocks of CBS-1 and be able to use this decomposition as a reference point for the next phases of the Operational Resilience Planning Methodology, particularly in identifying dependencies, assessing critical resources, and defining impact tolerances in accordance with regulatory expectations.

Below is a recommended decomposition of CBS-1 Retail Deposit and Account Services for the Philippine National Bank (PNB).

It is aligned to the operational resilience lens in BSP Circular No. 1203 (2024), which requires banks to identify critical operations, their supporting assets, interconnections, and interdependencies, disruption tolerances, and severe but plausible scenarios.

The Circular also makes clear that supporting assets include people, technology, information, facilities, clearing and settlement arrangements, and outsourced services.

PNB’s public product and channel information supports treating retail deposit servicing as a critical business service: PNB offers deposit accounts such as Debit Savings, Regular Checking, Passbook Savings, Budget Checking, My First Savings, Greencheck, Pensioner Savings, Top Saver Account, and foreign currency deposits, and PNB Digital supports enrolled deposit accounts, transaction viewing, transfers, bill payments, cardless withdrawal, checkbook orders, and savings account application through the mobile app.

Table P1: Detailed Processes for CBS-1 

Operational resilience requirements from BSP Circular No. 1203 relevant to this CBS

For a Philippine bank, the table above should not be treated as just a process map.

Under BSP Circular No. 1203, PNB should identify which of these retail deposit processes form part of a critical operation, identify the supporting assets behind them, and understand the interconnections and interdependencies across people, systems, facilities, clearing arrangements, and third parties.

The Circular says that identifying critical operations drives the subsequent steps of setting disruption tolerance and mapping dependencies.

The Circular also requires banks to set a tolerance for disruption for each identified critical operation, using at a minimum a time-based metric, and possibly other measures such as affected customers or transaction volumes/values.

Those tolerances must then be tested against severe but plausible scenarios.

Examples named by BSP include the “Big One” earthquake, a severe typhoon, a failure of a critical third-party service provider, payment and settlement disturbances, and simultaneous or coordinated cyberattacks or ransomware on banks.

For deposit and account services specifically, regulator-facing examples would include: disruption to branch withdrawals, outage of mobile banking access to deposit accounts, failure of account-opening/ KYC systems, unavailability of ATM or cardless withdrawal capability, prolonged reconciliation backlogs, and failure of outsourced or third-party components supporting customer onboarding, messaging, authentication, or channel connectivity.

BSP also says banks should ensure third parties supporting critical operations meet the bank’s operational resilience expectations and support the bank’s mapping and tolerance requirements.

The decomposition of CBS-1 Retail Deposit and Account Services into detailed Sub-CBS provides PNB with a clear operational blueprint of how one of its most critical customer services is delivered.

Each Sub-CBS represents a vital link in the service chain, and collectively, they illustrate the complexity and interdependency inherent in modern banking operations.

From onboarding and KYC processes to transaction handling, digital access, and incident response, the continuity of this service depends on the seamless functioning of multiple interconnected components.

More importantly, this structured breakdown enables PNB to meet the intent of BSP Circular No. 1203 by establishing a strong foundation for resilience analysis. With clearly defined processes, the bank is better positioned to identify critical dependencies, assess vulnerabilities, set realistic impact tolerances, and design severe but plausible scenarios for testing.

This ensures that the bank is not only prepared to withstand disruptions but also able to continue delivering essential services to its customers with minimal impact.

As PNB progresses to the next stages of its operational resilience journey, the Sub-CBS defined in this chapter will serve as a reference framework for deeper analysis and implementation, ensuring that resilience is embedded at every level of service delivery and aligned with both regulatory expectations and customer needs.
