As fraud becomes more sophisticated and increasingly powered by artificial intelligence, financial institutions are being forced to rethink how identity verification and trust operate across the banking ecosystem. The City of London Corporation’s proposal for a national digital verification network reflects a growing industry shift toward collaborative security infrastructure, where banks, fintech firms, and technology providers work together to create shared, interoperable identity frameworks capable of combating fraud at scale.
The City of London Corporation has issued a call for support from UK technology firms to develop a national digital verification network designed to combat the country’s escalating fraud crisis. The proposed network would establish a system of shared security among financial providers, allowing a person’s identity to be verified once by a trusted entity and subsequently recognised across all participating financial institutions. According to estimates from the City Corporation, this streamlined infrastructure could unlock £5 billion over the next five years by significantly reducing fraud losses and accelerating security processes.
The initiative comes as financial crime reaches critical levels, with City Corporation Policy Chairman Chris Hayward reporting that fraud currently costs banks more than £1 billion annually. Industry data reveals the severity of the situation; UK Finance recorded two million confirmed fraud cases in the first half of 2025 alone, resulting in losses of nearly £630 million. Furthermore, a Home Office study found that the broader social and economic cost of fraud reached £14.4 billion in the year ending March 2024, with £5.2 billion of that total specifically targeting businesses.
Experts highlight that the challenge for financial institutions is intensifying as criminals employ advanced technology. Dr Janet Bastiman, Chief Data Scientist at Napier AI, noted that artificial intelligence is making fraud attempts increasingly sophisticated, making continuous monitoring both essential and more difficult to execute. She emphasised that, because fraud is a predicate crime to money laundering, which costs the UK an estimated $195 billion per year, using technology to stop fraud at the source is vital to protecting the wider economy from complex criminal networks. This call for a unified digital network follows other recent enforcement efforts, including the fraud reporting service established by the City of London Police in early 2026.
What this means for the industry
- Fraud prevention is evolving from institution-level controls toward ecosystem-wide collaboration
- Shared digital identity infrastructure could significantly reduce onboarding friction and duplicate verification processes
- AI-driven fraud is accelerating the need for real-time, network-based security models
- Banks and fintech firms may increasingly rely on interoperable digital trust frameworks rather than isolated systems
- Digital identity is becoming critical infrastructure for the future of financial services and cross-platform security
- Regulatory and industry cooperation will play a major role in scaling trusted digital verification networks
- Institutions that fail to modernise identity and fraud prevention capabilities risk higher operational and financial exposure
