CBS-4 Corporate Cash Management and Collections

Scenario testing constitutes a core tenet of the operational resilience framework. It enables Metrobank to rigorously challenge the resilience of its Corporate Cash Management and Collections service by exposing critical processes to severe yet plausible disruption scenarios.

This structured test regime validates the bank’s ability to absorb shocks, adapt in real time, and continue delivering essential client services without breaching impact tolerances.

The scenario constructs integrate cyber and ICT risks, reflecting the heightened threat landscape in digital banking operations, while evidencing proactive risk mitigation and readiness actions undertaken by Metrobank.
