The financial services sector has experienced a seismic shift in 2025 driven by rapid advances in artificial intelligence (AI) technologies, alongside ongoing IT challenges. Computer Weekly takes a comprehensive look back at the most significant stories this year, highlighting AI’s transformative impact, persistent banking IT outages, and strategic leadership changes.
1. AI Roles: The Only Safe Jobs in Banking
Artificial intelligence emerged as the dominant force reshaping banking jobs in 2025. A report by industry benchmarking firm Evident revealed that AI-related roles are now considered the safest positions within the sector. With one in every 50 employees recruited by the top 10 banks working in AI functions, it is clear that the adoption of AI is radically altering workforce compositions. While institutions expect rapid return on investment from AI, this inevitably means a reduction in traditional roles as AI systems take over repetitive and analytical tasks.
2. Lloyds Bank Invests in AI Training for Senior Leaders
Recognizing that AI literacy is critical at all levels, Lloyds Banking Group partnered with training provider Cambridge Spark to equip over 200 senior leaders with the knowledge necessary to leverage AI effectively. This initiative underscores the growing understanding that leadership must adapt to the AI revolution to maintain competitiveness and steer organizational transformation confidently.
3. ING’s CTO Emphasizes AI as a Core Transformation Force
Daniele Tonella, CTO of ING, shared insights on how the bank integrates generative AI (GenAI) as a fundamental element of innovation, rather than a mere technology experiment. Tonella described ING’s four-layer IT strategy comprising reliability, scalable technology platforms, quality control, and innovation—with AI driving the latter. This balanced approach ensures IT robustness while harnessing AI’s potential to transform customer experiences.
4. Bloomberg’s Commitment to AI Amid Sector Complexity
Wayne Barlow, head of terminal products at Bloomberg, detailed the company’s efforts to embed GenAI into its services to meet the evolving demands of the financial ecosystem. Given Bloomberg’s pivotal role in providing timely information and analytics, embracing AI has become essential for maintaining market leadership and enabling smarter decision-making across banking and finance.
5. The Bank of England’s Quiet ‘Big Bang’ Upgrade
One of the financial sector’s most critical IT projects—the replacement of the Bank of England’s real-time gross settlement (RTGS) system—reached significant milestones in 2025. Processing £800 billion in payments daily, the successful, staged overhaul led by CIO Nathan Monk was hailed as “a hell of a journey,” demonstrating how complex legacy systems can be modernized without disrupting nationwide financial operations.
6. ASN Bank’s Strategic Integration and Cybersecurity Overhaul
ASN Bank in the Netherlands undertook an ambitious initiative to unify its branding and systems, involving extensive core infrastructure revamps and cybersecurity enhancements. CTO Sebastiaan Kalshoven likened this continuous improvement process to his experience as a swimming coach, emphasizing persistence and incremental gains as keys to success in digital transformation.
7. Barclays Suffers Major IT Outage on Crucial Payday
Banking IT outages remain a stubborn challenge. Barclays experienced a significant disruption on a key HMRC deadline day in January, leaving customers unable to access online banking services or execute payments. The incident highlighted the sector’s vulnerability at critical transactional moments, affecting customer trust and financial operations.
8. ‘Bankenstein’: Complexity and Cost-Driven Banking Crashes
Experts analyzing frequent banking IT failures point to an overly complex “spaghetti” technology infrastructure likened to “technology Jenga.” Additionally, some financial institutions have made cold calculations weighing the cost of achieving near-perfect 99.999% uptime against paying compensation for downtime, often opting for the latter. This pragmatic but risky approach suggests banking IT outages will continue to surface.
9. US AWS Outage Raises Questions in UK Financial Sector
Dependency on third-party cloud providers was starkly exposed when a major outage in Amazon Web Services (AWS) in the United States disrupted UK tax offices and several banking firms, including Lloyds. The incident has prompted government inquiries into the resilience of cloud service providers and the implications for critical financial infrastructure.
10. AI-Powered Automation and the Future Workforce
AI systems such as the virtual assistant “Dave” are beginning to perform roles equivalent to thousands of human workers without fatigue, signifying a profound shift in operational efficiency and workforce requirements. This advancement brings promise but also challenges for financial services organizations as they navigate employee retraining, ethical considerations, and regulatory compliance in a rapidly evolving AI landscape.
As 2025 draws to a close, the financial services industry stands at a historical crossroads. Artificial intelligence has emerged not just as a technological innovation but as a core pillar redefining jobs, leadership, infrastructure, and customer experience. Coupled with ongoing IT resilience challenges, the financial sector’s journey through digital transformation remains dynamic and complex. Computer Weekly will continue monitoring these shifts as the industry evolves in 2026 and beyond.
