The financial services sector experienced a year of seismic shifts in 2025, driven largely by emerging technologies with artificial intelligence (AI) taking center stage. Computer Weekly’s annual roundup highlights the top 10 stories that have reshaped banking and finance this year, detailing both the opportunities and the challenges faced by institutions amid rapid innovation.
1. Artificial Intelligence Emerges as the ‘Only Safe Jobs’ in Banking
AI’s growing presence in banking has brought both promise and apprehension. Reports indicate that investment in AI technologies is generating swift returns, but inevitably at the cost of workforce reductions. According to benchmarking firm Evident, AI roles represent the only truly secure jobs in the sector, with 2% of employees at the top 10 banks now engaged in AI-related roles. This trend underscores how human resources are being realigned towards technology-driven positions.
2. Lloyds Bank Invests in AI Training for Senior Leaders
Recognizing that AI’s impact extends beyond frontline roles, Lloyds Banking Group launched a major initiative to upskill its leadership. Over 200 senior managers are receiving specialised AI training via Cambridge Spark to ensure a comprehensive organisational understanding of artificial intelligence’s potential. This move addresses concerns that lack of AI literacy among executives could hinder innovation and competitiveness.
3. Insight from ING’s CTO Daniele Tonella on GenAI Integration
In an exclusive interview, ING Bank’s Chief Technology Officer Daniele Tonella revealed the bank’s strategic approach to generative AI (GenAI). Rather than treating AI as a novelty, ING integrates it as a fundamental force underpinning core digital transformation efforts. Tonella describes a four-layer IT architecture prioritising reliability, scalable platforms, quality control, and innovation—the latter being where GenAI initiatives are positioned to drive future growth.
4. Bloomberg’s Tech Leadership Discusses GenAI Adoption
Bloomberg, a cornerstone of financial information services, shared its perspective through an interview with Wayne Barlow, head of terminal products. The firm is embracing GenAI to enhance decision-support tools for clients across the financial ecosystem. Barlow highlighted the challenges of integrating cutting-edge AI technologies while maintaining information accuracy and system integrity.
5. Bank of England’s ‘Quiet Big Bang’ in Core System Replacement
Over an eight-year journey initiated in 2017, the Bank of England completed a phased overhaul of its real-time gross settlement (RTGS) system, an infrastructure challenged with processing around £800 billion daily. Technology lead Nathan Monk described the extensive effort required to modernize this critical backbone, emphasizing minimal operational disruption despite the system’s centrality to national financial stability.
6. ASN Bank’s Journey to Brand Integration and Cybersecurity Enhancement
ASN Bank in the Netherlands underwent a significant brand consolidation requiring deep IT integration and infrastructure refurbishment. CTO Sebastiaan Kalshoven likened the iterative improvement process to his prior experience in swimming coaching, stressing continuous development and resilience. Cybersecurity enhancements were a key focus during the transition to safeguard digital assets.
7. Barclays Faces Major IT Outage on HMRC Deadline Day
Financial IT disruptions remain a vexing reality. Barclays experienced a high-profile outage in January coinciding with a critical tax deadline, leaving customers unable to access online banking, execute payments, or contact customer service. The incident highlighted the sector’s vulnerability to technology failures at times of peak demand.
8. ‘Bankenstein’: Why Banking IT Crashes Persist
Experts attribute recurrent banking IT outages to fragmented and overly complex legacy systems dubbed “spaghetti” architectures. Financial institutions operate a delicate balance, sometimes accepting brief service disruptions as more cost-effective than exhaustive infrastructure upgrades. The “technology Jenga” analogy encapsulates the risky dependencies embedded within aging IT environments.
9. Impact of US AWS Outage on UK Tax Office and Banks Raises Governance Questions
Reliance on third-party cloud providers caused widespread disruption when an Amazon Web Services (AWS) outage in the US affected critical UK services, including Lloyds Banking Group and government tax offices. The incident spurred debate about the risks of over-dependence on US-based Big Tech firms for essential infrastructure, prompting calls for greater oversight and diversification.
10. The Future of Financial Services IT: Navigating Continuous Innovation and Risk
These stories illustrate the dual-edged nature of technological advancement in financial services. While AI and digital transformation promise efficiency and new capabilities, they also introduce operational risks and workforce challenges. Banking leaders must skillfully manage this complexity to harness technology’s benefits without compromising stability or security.
As 2025 draws to a close, the financial services industry stands at a pivotal moment. The year’s developments underscore the critical role of AI and resilient IT systems in shaping the future of banking. Organizations that embrace innovation thoughtfully and invest in people and infrastructure will be best positioned to thrive in this rapidly evolving landscape.
