Payments and Funds Transfer Services (CBS-2) represent one of the most systemically important critical business services of China Construction Bank (Malaysia) Berhad.
These services enable retail, SME, and corporate customers to move funds domestically and across borders, settle obligations, execute payroll and supplier payments, and interact with digital payment ecosystems. Disruptions to these services can result in immediate financial loss, regulatory breaches, reputational damage, and systemic market impact.
This chapter establishes appropriate impact tolerances for each Sub-CBS under CBS-2, in alignment with operational resilience regulatory expectations. Impact tolerances define the maximum tolerable level of disruption, expressed through measurable metrics such as Maximum Tolerable Downtime (MTD) and Maximum Tolerable Data Loss (MTDL).
The objective is to ensure the bank can continue delivering critical payment services within acceptable disruption thresholds, even under severe but plausible scenarios such as cyber incidents, system outages, third-party failure, or infrastructure disruption.

These tolerances must be validated through scenario testing, cyber resilience assessments, and third-party concentration risk reviews.
Establishing impact tolerances for CBS-2 Payments & Funds Transfer Services provides China Construction Bank (Malaysia) Berhad with a measurable framework to withstand disruption while protecting customers, maintaining regulatory compliance, and preserving financial stability.
By clearly defining Maximum Tolerable Downtime and Maximum Tolerable Data Loss for each Sub-CBS, the bank transitions from traditional business continuity planning to a forward-looking operational resilience model centered on service continuity rather than system recovery alone.
Going forward, these tolerances must be regularly tested under severe but plausible scenarios, including cyberattacks, infrastructure outages, third-party service disruption, and liquidity stress events.
Continuous improvement, governance oversight, and board-level accountability will ensure that CBS-2 remains resilient, adaptive, and aligned with evolving regulatory expectations and digital payment ecosystem risks.
