CBS-3 Corporate & SME Banking

In the evolving banking landscape, operational resilience is critical to ensure that essential banking services continue to function effectively, even during disruptions.

Establishing impact tolerances is a fundamental step in operational resilience, as it defines the maximum level of disruption a critical business service (CBS) can sustain before it affects customers, regulatory obligations, or the bank’s strategic objectives.

For CBS-3 Corporate & SME Banking, this exercise ensures that AmBank maintains service continuity for both corporate clients and SMEs, who rely heavily on financing, cash management, and trade services to operate smoothly.

This chapter focuses on setting appropriate impact tolerances for each sub-process (Sub-CBS) under Corporate & SME Banking. By defining thresholds for maximum tolerable downtime (MTD) and maximum tolerable data loss (MTDL), AmBank can identify vulnerabilities, prioritise mitigation strategies, and enhance overall resilience.

The table below presents the proposed impact tolerances, customer and regulatory considerations, current resilience status, and recommended actions for each Sub-CBS.

Establishing clear impact tolerances for CBS-3 Corporate & SME Banking enables AmBank to quantify its risk exposure and operational limits during disruptions.

By defining MTD, MTDL, and associated customer and regulatory impacts, the bank can prioritise mitigation strategies, allocate resources efficiently, and maintain confidence among clients and regulators.

This proactive approach ensures that critical banking services, from corporate lending to digital banking platforms, remain resilient under adverse conditions.

Continuous monitoring, testing, and improvement of these impact tolerances will allow AmBank to not only meet regulatory expectations but also uphold its commitment to uninterrupted, high-quality service for corporate and SME clients.
