CBS-1 Securities Trading & Execution 

Introduction

Operational resilience requires more than identifying critical business services; it demands a structured mapping of the interconnections and interdependencies that enable those services to function end-to-end.

For CBS-1 Securities Trading & Execution at Maybank Investment Bank, the delivery of trading services depends on a tightly integrated ecosystem of people, processes, technology platforms, market infrastructures, and third-party providers.

Disruptions in any of these components—whether internal system failures, market connectivity outages, human resource constraints, or external clearing disruptions—can impair the firm’s ability to execute and settle trades within its impact tolerance.

This dependency mapping exercise systematically identifies and documents the critical internal and external resources supporting each Sub-CBS.

By understanding how these elements connect and interact, management can better assess concentration risk, identify single points of failure, prioritise recovery, and determine the resilience enhancements needed to safeguard trading operations.
