By Karl Flinders, Chief Reporter and Senior Editor EMEA
Published: 23 December 2025
The financial services industry in 2025 has been marked by seismic technological shifts and significant IT disruptions that have transformed the banking landscape. Artificial intelligence (AI), and in particular generative AI (GenAI), has emerged as a dominant force, driving innovation, efficiency, and dramatic changes in workforce dynamics. At the same time, critical IT outages and legacy system challenges have underscored vulnerabilities in banking infrastructure. Computer Weekly has compiled its top 10 financial services stories of 2025 to highlight these developments and their implications.
1. Artificial Intelligence Roles Become the Safest Jobs in Banking
AI has not only revolutionized banking technology but also reshaped employment within the sector. Industry analysts predict rapid returns on AI investments leading to workforce reductions in traditional roles. A report from banking benchmarking firm Evident revealed a stark trend: AI-related positions are increasingly replacing conventional jobs, with about one in every 50 employees at the top 10 banks now working in AI-focused capacities. These AI roles are widely seen as the âonly safe jobsâ in the banking domain as institutions lean heavily into automation.
2. Lloyds Bank Prepares Senior Leaders for AI Era
Recognizing the critical need for leadership to fully grasp AIâs impact, Lloyds Banking Group partnered with Cambridge Spark to deliver artificial intelligence training to over 200 senior managers. This initiative aims to embed AI understanding at strategic decision-making levels, ensuring the bank remains competitive and capitalizes effectively on AI capabilities. The move highlights that AI education is no longer just for technical staff but a necessary asset for executives.
3. ING CTO Daniele Tonella on Embedding Generative AI
Daniele Tonella, Chief Technology Officer at ING, shared insights with Computer Weekly on the bankâs structured approach to GenAI adoption. Tonella described a four-layer IT architecture at ING: focusing on reliability, scalable technology platforms, quality control, and innovationâwith GenAI initiatives clustered within the innovation layer. His approach ensures generative AI is not treated as a mere technological novelty but as a cornerstone for digital transformation.
4. Bloombergâs Wayne Barlow Discusses GenAI Challenges and Strategies
Wayne Barlow, head of terminal products at Bloomberg, provided an interview covering the companyâs integration of GenAI technologies into its service offerings. Bloomberg, a critical player in financial information dissemination, is adapting to AI-driven changes to enhance data delivery and decision-making tools for clients. Barlow underscored ongoing challenges faced as the company balances innovation with data accuracy and compliance.
5. The Bank of Englandâs Core System Replacement: A Quiet âBig Bangâ
One of the yearâs most significant undertakings was the Bank of Englandâs phased replacement of its Real-Time Gross Settlement (RTGS) systemâthe infrastructure that processes approximately ÂŁ800 billion in daily payments. CIO Nathan Monk described the multi-year project as âa hell of a journey,â carefully balancing innovation with operational continuity to avoid disruptions in the nationâs financial plumbing.
6. ASN Bankâs CTO on Brand Integration and Cybersecurity Enhancements
ASN Bank in the Netherlands embarked on a comprehensive IT overhaul to unify its brand platforms while strengthening cybersecurity. CTO Sebastiaan Kalshoven likened his approach to his experience as a swimming coachâfocused on continuous improvement. Kalshoven detailed how the bank tackled integration challenges and infrastructure revitalization to enhance customer experience and safeguard operations.
7. Barclays Suffers Major IT Outage on Crucial HMRC Deadline Day
In January, Barclays experienced a severe IT outage coinciding with a key HM Revenue and Customs (HMRC) deadline. The disruption denied customers access to web and mobile banking, payment services, and customer support. The incident echoed a persistent risk in the banking sector: significant IT failures often strike at the most critical financial moments, undermining trust and operational reliability.
8. Experts Attribute Banking System Crashes to âSpaghettiâ IT Architectures
Analysts point to inherited fragmented and complex IT systemsâdescribed as âspaghettiâ architecturesâthat resemble a precarious game of Jenga, where one failure can cascade into wide outages. A pragmatic calculation often drives investment decisions: the cost to achieve near-perfect uptime (such as 99.999% availability) can exceed the financial impact of occasional downtime and customer compensations. This cold calculus contributes to ongoing system instability challenges.
9. US Amazon Web Services (AWS) Outage Disrupts UK Banks and Public Sector
The banking sectorâs growing reliance on major cloud providers was put under the spotlight when an AWS outage in the United States affected key UK financial institutions, including Lloyds Banking Group, and various government services. This incident raised concerns about over-dependence on US-based technology giants, prompting calls for greater resilience and diversification in cloud infrastructure sourcing.
10. The Dawn of AI-Driven Job Transformation: Introduction of âDaveâ
Perhaps the most emblematic change of 2025 was the unveiling of AI systems capable of performing the tasks of thousands of employees swiftly and efficiently. One such AI, nicknamed âDave,â represents the shift towards automation that may drastically reduce human roles in routine banking functions. While promising cost reductions and operational streamlining, these technologies also brought significant challenges around workforce transition, ethical considerations, and organizational culture.
In summary, 2025 has been a transformative year for financial services IT, dominated by the rapid ascendancy of AI technologies, complex system renewal efforts, and the realities of digital disruption. Financial institutions are increasingly balancing innovation with the critical need for reliable, secure, and customer-centric services. As these trends continue unfolding, stakeholders across the sector will be closely monitoring how technology reshapes bankingâs future landscape.
