AI is already disrupting every area of the Financial Services Industry, and is being included in almost every strategic conversation around technology-enabled transformation. This transformation is exemplified by industry leaders like JP Morgan Chase. CEO Jamie Dimon has championed a £12 billion annual investment in data and technology, overseeing over 400 AI use cases. These include fraud detection, customer service improvements and operational efficiencies across the bank. The core platforms underpinning the industry risk buckling under the weight of modernisation. AI is gradually loosening the components of legacy institutions and presenting fresh opportunities. These are scalable, resilient and adaptable to the agile needs of Financial Services. Through this reimagining of core platforms, those who choose to act now can expect to leapfrog their competition. Meanwhile, those who fail to act now risk obscurity, lack of productivity and being disregarded by their consumer base.
The transition to new architectures
For decades, banks have relied on legacy systems to power their core operations. These often ageing platforms are becoming increasingly difficult and expensive to maintain. They have been built both in languages not commonly used and architected with a different business reality in mind. Many frequently lack the flexibility required to meet the demands of today’s digital-first customers. They also struggle to integrate with modern financial technologies. A significant challenge facing organisations is the accumulation of technical debt. There is a cost to additional work or rework caused by choosing quick or limited solutions over more robust, maintainable approaches. Over time, this can lead to significant issues that compound the challenges of legacy systems.
This lack of nimbleness is often the byproduct of a Frankenstein approach to architectural systems. Many financial institutions have traditionally built new features or attempted to fuse together two platforms. This is a delicate balancing act, requiring extensive planning and careful execution. If done with limited oversight, challenges can arise. These include operational disruptions, increased security risks and obvious incompatibility issues. The high risks and cost burdens associated with maintaining legacy platforms has led many banks to reconsider traditional merger approaches. Increasingly opting for modern, cloud-based microservices driven solutions that offer enhanced scalability, security and integration potential.
Meeting the challenge
As the industry establishes governance around this necessary transition, core platforms are being replaced by newer, more adaptable microservice-based architectures. Navigating this evolution requires leveraging an industry partner with a deep understanding of the complexities and risks involved. There are challenges moving from monolithic core systems to flexible, modern frameworks.
If we think back five years or so, many players in the market were already aware of this critical shift. Companies like Misys and Avaloq were acquired by private equity firms and given substantial investment to advance digital initiatives, developing solution suites. The reason for this was clear, everyone understood the market was changing. However, the challenge still remains in managing the migration of large, complex platforms. The key question has always been how to de-risk these migrations when moving to newer architectures. This is an issue across organisations, and it is something that we at Altimetrik actively work with clients in financial services to address.
Data first with AI
If we consider platforms such as core banking or payments systems, the data generated from these transactions should, in theory, hold value. However, gaining insights from legacy platforms is significantly more challenging and the cost of extracting and utilising that data is often prohibitive. It is here that a data-driven approach to AI must be agreed upon.
High-quality, accurate data lies at the core of every successful AI implementation. AI thrives on data; the more precise the data, the better the AI can learn and provide reliable insights. This fundamental truth highlights the importance of data integrity within the AI ecosystem. However, many financial institutions are struggling in this area, both in effectively using internal data and leveraging accurate, timely external data. As companies grow, their data environments become increasingly complex, adding to these challenges.
As financial services organisations expand, they often face the challenge of data silos, declining data quality and scattered, disconnected data repositories. This leads to a fragmented data ecosystem. It can limit AI’s potential to deliver meaningful insights and drive improvements. This transformation requires active leadership from the top. Successful digital transformation depends on executive-level commitment and understanding. Leaders like Charles Scharf of Wells Fargo demonstrates how CEO ownership of data and AI initiatives drives organisation-wide adoption and success. Their hands-on approach ensures these technologies aren’t just IT projects, but core business strategy enablers.
A Single Source of Truth with AI
To overcome this, financial institutions should establish a Single Source of Truth (SSOT) and in doing so move away from older, somewhat clumsy core platforms. An SSOT will provide a unified, consistent view of data across the organisation. This accelerates decision-making with greater confidence. As demonstrated by successful implementations across the industry. For exmple, Bank of America’s AI-powered virtual assistant Erica providing personalised financial advice to Wells Fargo’s modernised data infrastructure. This enables enhanced risk assessment and management. By centralising core data, an SSOT enables the identification of operational inefficiencies, better monitoring of customer behaviours and effective execution of strategies to foster growth.
The key question is how to successfully de-risk this transition from a fixed cost base to a more flexible, agile one. This transition is essential for becoming an outcomes-focused business with greater adaptability. So, how can technology help achieve this?
One approach involves what is often (unfortunately) referred to as a Strangler Pattern. Instead of a wholesale shift from one platform to another, this modulated approach guides clients on a journey that focuses on gradually moving specific functionalities. By decomposing the legacy system function by function, we rebuild each component within the new platform. This allows the old system to run in parallel until fully replaced. Thus shrinking the monolithic structure in a manageable, low-risk way. It is a method preferred by many large financial services players when they move to become digital businesses.
By working within a digital business methodology that prioritises outcomes over technology, we gain significant advantages. The beauty of this function is its flexibility. When implementing a new function, the management of a FS firm may discover it isn’t meeting expectations or fulfilling business needs. And yet these clients still have the security of the old platform to fall back on and can easily revert back to the original system and refine the new function before trying again. This way of working ensures a safety net. It can reduce risk and enable iterative improvements without causing major disruptions to business operations.
The full picture
The transformation of core platforms through AI presents both immense opportunity and significant challenges. Those institutions willing to embrace this change, adopting data-first approaches and modern architectures, are poised to redefine the industry landscape. The transition, whilst complex, can be managed through measured strategies allowing for gradual, low-risk modernisation. As we move forward, the success of financial institutions will increasingly hinge on their ability to harness AI’s potential. They will need to create unified data ecosystems and adapt to the evolving needs of the digital age. Financial services businesses must embrace AI and modernise their core platforms or risk becoming as obsolete as a floppy disk.
