As a leading global financial market infrastructure and data provider, LSEG delivers high-volume, real-time, and low-latency market information to exchanges, trading firms, financial institutions, investment managers, and market participants worldwide.
These services support critical business activities such as trading, price discovery, risk management, investment decision-making, analytics, and regulatory reporting.
Given the significant reliance of market participants on timely and accurate market information, any disruption to market data services can rapidly propagate across financial markets and create operational, financial, and reputational impacts.
From an operational resilience perspective, identifying and decomposing a Critical Business Service (CBS) into its detailed operational components enables organisations to understand how services are delivered and where vulnerabilities may exist.
For LSEG, breaking down CBS-2 Market Data Distribution Services into detailed Sub-CBS processes provides a basis for analysing operational dependencies across people, processes, technology, facilities, and third parties that support the end-to-end market data ecosystem.
The purpose of this chapter is to identify and document the detailed business processes (Sub-CBS) that collectively support the delivery of CBS-2 Market Data Distribution Services within LSEG’s operational resilience programme.
By decomposing the high-level service into granular operational activities, this chapter provides readers with a structured understanding of how market data is acquired, processed, validated, distributed, monitored, and recovered during disruptions.
Readers should use this chapter as a foundational reference for subsequent operational resilience activities, including dependency mapping, process and resource analysis, impact tolerance establishment, severe-but-plausible scenario identification, and scenario testing.
The objective is to enable stakeholders to understand the operational architecture that supports market data services and to identify critical resilience considerations across the service lifecycle before progressing to later implementation stages.

|
2.13 |
Historical Data Capture and Archiving |
Captures and stores historical market information for replay, analytics, audit, and regulatory use. |
|
2.14 |
Customer Delivery Channel Integration |
Supports integration with customer systems, trading platforms, desktops, and third-party market data consumption channels. |
|
2.15 |
Exception Handling and Data Recovery Management |
Detects feed interruptions, sequence gaps, corrupted messages, or missing updates and initiates recovery procedures. |
|
2.16 |
Market Data Monitoring and Performance Surveillance |
Continuously monitors latency, throughput, feed health, and service quality metrics. |
|
2.17 |
Incident Response and Service Restoration |
Coordinates operational response activities in the event of data distribution failures or service disruptions. |
|
2.18 |
Regulatory Reporting and Data Compliance Monitoring |
Ensures compliance with licensing obligations, audit requirements, market regulations, and supervisory expectations. |
|
2.19 |
Cybersecurity Monitoring for Data Infrastructure |
Monitors market data environments for cyber threats, including DDoS attacks, malware, credential compromise, and unauthorised access attempts. |
|
2.20 |
Business Continuity and Resilience Administration |
Maintains resilience procedures, redundancy arrangements, disaster recovery capabilities, and operational recovery plans supporting uninterrupted market data services. |
The CBS-2 Market Data Distribution Services capability at LSEG comprises a highly interconnected set of operational, technological, and governance processes that collectively ensure the reliable delivery of market information to global financial markets.
These twenty Sub-CBS components represent the complete value chain from market data acquisition through validation, processing, enrichment, distribution, customer access management, and resilience operations.
Understanding these detailed processes is fundamental to Operational Resilience planning.
By identifying each Sub-CBS, LSEG can systematically map dependencies, assess vulnerabilities, establish impact tolerances, perform severe-but-plausible scenario testing, and implement appropriate controls to maintain service continuity.
This structured decomposition also enables clearer accountability, improved risk management, and stronger recovery capabilities across the market data ecosystem.
In subsequent Operational Resilience activities, these Sub-CBS processes will serve as the foundation for dependency mapping, interconnection analysis, impact tolerance setting, and resilience testing, ensuring that LSEG can continue delivering critical market data services even during significant operational disruptions.
