Barclays Expands Anthropic Partnership to Scale Claude Across Global Operations

Barclays is expanding its strategic collaboration with Anthropic to integrate secure, enterprise-grade Claude AI systems across its global operations. The bank aims to accelerate software development, modernize legacy systems, and improve operational efficiency through this rollout.

Developer Adoption Targets

Barclays projects that Claude Code adoption will reach 50% of its developer population by the end of 2026, with the goal of reaching a majority of software engineers in 2027. This initiative is part of a broader effort to embed AI as an agentic capability within how the bank builds, tests, secures, and operates technology.

Customer Servicing and Knowledge Assistance

The partnership already includes the Colleague Knowledge Assistant, a tool powered by Claude through a retrieval-augmented generation architecture. Live since 2025, the assistant supports Barclays UK employees serving over 20 million retail customers. Key metrics include:

• 16,000+ colleagues have adopted the assistant.
• Over 1 million searches have been handled.
• The tool provides faster access to information, resulting in quicker customer support.

Global Markets Efficiency

Within Barclays' Global Markets business, Claude models streamline the processing of client enquiries. The system classifies, enriches, and determines the optimal processing route for incoming emails, allowing operations teams to prioritize requests more effectively. The platform currently processes approximately 120,000 emails each day, reducing manual handling and helping colleagues identify relevant information efficiently.

Governance and Oversight

Responsible deployment remains central to the expansion. Barclays applies robust governance, security controls, and human oversight to all AI use cases. Anthropic’s Chief Commercial Officer, Paul Smith, emphasized that Barclays’ high standards for AI security and oversight are critical given the bank's global reach and regulatory environment.
