LSEG Strengthens AWS Partnership to Accelerate Cloud Transformation Across Key Divisions

Subscribe to our newsletter

The London Stock Exchange Group (LSEG) has extended its strategic collaboration with Amazon Web Services (AWS), naming AWS as its preferred cloud provider for the Markets, Risk Intelligence, and FTSE Russell divisions. The move deepens an existing relationship that forms a central part of LSEG’s broader digital transformation strategy.

The latest agreement will see LSEG continue its migration of internal systems to AWS’s cloud infrastructure, aiming to enhance operational resilience, strengthen security, and deliver new services to customers more efficiently. LSEG’s Risk Intelligence division will leverage Amazon Bedrock to enable faster and more accurate risk analysis, helping clients to better anticipate market volatility and regulatory changes.

In the FTSE Russell division, AWS’s capabilities will support the provision of historical and quantitative index data, allowing institutional clients to identify deeper market trends, accelerate time-to-insight, and reduce operational costs. LSEG Markets will also use AWS Outposts to deliver scalable, resilient services directly to customers, combining cloud flexibility with the low-latency demands of trading environments.

The partnership with AWS complements LSEG’s broader investment in cloud technologies, which form a cornerstone of the Group’s long-term strategy. In December 2022, LSEG and Microsoft entered into a 10-year strategic partnership under which LSEG’s data infrastructure would be architected using the Microsoft Cloud, with both companies jointly developing new products and services for data and analytics. As part of that agreement, Microsoft also agreed to acquire shares in LSEG, resulting in Microsoft holding an approximately 4% equity stake in the Group. Alongside its work with Microsoft, LSEG’s collaboration with AWS has focused on strengthening data hosting, enhancing risk modelling capabilities, and enabling cloud-native services across its Markets, Risk Intelligence and FTSE Russell divisions.

Beyond efficiency gains, the extended collaboration with AWS positions LSEG to meet growing regulatory demands for data security, residency, and compliance across different jurisdictions. AWS’s global infrastructure has been key to supporting LSEG’s compliance efforts, particularly as financial institutions face increasingly complex data governance requirements.

The move also strengthens LSEG’s competitive position against other financial data providers such as Bloomberg and ICE, both of which are pursuing similar cloud transformation strategies. By building a more agile, cloud-based platform, LSEG aims to offer clients more advanced analytics, deeper insights, and faster product innovation in an increasingly digital financial services landscape.

Daniel Maguire, Group Head of Markets, LSEG, commented: “Our ongoing collaboration with AWS is an important part of the Group’s cloud strategy. LSEG’s role as a leading global market infrastructure and data provider means that operational resilience is the foundation of everything we do – and cloud services are the cornerstone of our approach. We look forward to working with AWS to deliver innovative products and an enhanced experience for our customers to support their trading and risk management activity.”

Tanuja Randery, Managing Director, AWS EMEA, added: “AWS has deep expertise in meeting the unique needs of financial markets participants around the world, and we are excited about the opportunity to scale our work with LSEG. We look forward to helping LSEG drive innovation for their financial services customers and improve resilience.”
