CBS-2 Payments and Fund Transfers

In the context of Metrobank’s operational resilience framework, the critical business service (CBS) CBS-2 Payments and Fund Transfers plays a vital role in the financial ecosystem, facilitating secure, accurate, and timely transactions for clients.

As Metrobank continues to strengthen its operational resilience, establishing impact tolerances for its critical business services is essential.

Impact tolerance refers to the maximum level of disruption or loss that can occur in a critical business service without severely affecting the institution's ability to meet customer, regulatory, and business requirements.

This chapter aims to define the appropriate impact tolerances for CBS-2 Payments and Fund Transfers, encompassing all sub-CBS components.

By setting clear parameters for acceptable levels of downtime, data loss, and impact, Metrobank can ensure continuity of service even in adverse situations, aligning with regulatory requirements and maintaining stakeholder confidence.
