The Power of Orchestration and Digital Ledger Platforms: How UK Banks can offer payment and fintechs at speed

Guest blog by Dhritiman Mukherjee, Managing Partner, Banking & Financial Services and Dr. Marc Brogle, Principal Advisor, Modernization & Transformation at DXC Technology

Introduction 

As the financial sector rapidly evolves, traditional UK banks face mounting pressure to provide new payment options, digital experiences, and seamless integration with emerging fintech services. However, legacy core banking systems often make this transition slow and difficult. So, the question is: how can they modernise their infrastructure without the disruption and risk of replacing their core systems? 

 

The Challenge: Legacy Cores and the Innovation Gap 

Most UK banks operate on legacy core banking platforms, often running on mainframes that are decades old. These systems are robust but inflexible. When it comes to adding new payments functionalities or launching digital products, they pose significant hurdles: 

  • Slow integration cycles: New features can take months or years to implement. 
  • High costs and operational risk: Core changes risk outages, data loss and compliance issues. 
  • Limited agility: Responding to market trends or regulatory changes is challenging. 
  • Skills gap: Difficulty in finding resources with the right skills  

 

This innovation gap is particularly acute as customers demand real-time payments, embedded finance, digital assets and superior experience. 

 

The Role of Orchestration and Digital Ledger Platforms 

Traditional core banking systems, often running on mainframes, have provided dependable service for decades. Yet, they are not built to incorporate the rapid pace of change in today’s payments ecosystem. Integrating new payment methods (such as real-time payments, “buy now, pay later” solutions, and digital wallets) can be slow, expensive, and complex. 

Orchestration and digital ledger platforms offer a pragmatic solution. Rather than requiring a full-scale core replacement, banks can adopt an accelerated approach with the following features: 

  • Centralised orchestration: These platforms act as payment hubs, managing transactions, data flows, and risk and compliance across multiple rails and providers. 
  • Simplified integration: By exposing legacy services through modern APIs, orchestration platforms make it easier to connect with fintech partners and launch new products quickly. 
  • Operational efficiency: Consolidating payment processing reduces manual intervention, lowers costs, and improves resilience. 
  • Intelligent routing: Transactions are automatically directed to the fastest, most cost-efficient payment rails. 
  • Real-time compliance: Fraud, AML, and KYC monitoring are embedded by design into payment flows, reducing manual intervention and risk. 
  • Agility and scalability: Banks can respond rapidly to market trends, regulatory changes, and member demands. 

 

Benefits for Banks 

Adopting this approach brings several advantages: 

  • Faster time-to-market: New payment functionalities can be added without costly and time-consuming changes to the core system. 
  • Enhanced customer experience: Banks can offer innovative services, such as instant payments and embedded finance, meeting the expectations of today’s consumers. 
  • Reduced risk: Phased migration and modular integration minimise operational disruption and compliance risks. 
  • Future-proofing: Banks can adapt to new technologies and regulatory requirements without being held back by legacy systems. 

 

Bridging the Innovation Gap 

The gap between what legacy cores can deliver and what customers expect is widening. Orchestration and digital ledger platforms bridge this gap by enabling banks to: 

  • Integrate with third-party payment providers (e.g., Ripple, Klarna, “Pay now, buy later”, Coinbase etc.) in an agile manner. 
  • Consolidate data from multiple sources for improved compliance and analytics. This can  also provide greater insight into customer preferences 
  • Support digital first experiences, such as mobile wallets and apps, without overhauling the core. 
  • Support digital assets, including crypto and tokenised deposits. 
  • Retire costly sidecar systems by consolidating their functionality. 
  • Shift workloads to the cloud without disturbing mission-critical systems. 

 

Why Now? 

The financial services landscape is evolving rapidly. Regulatory changes, customer expectations, and competitive pressures demand greater agility. Banks that embrace Orchestration and Digital Ledger Platforms can position themselves as leaders in innovation, offering customers the latest payment options and digital services without the risk and cost of a full core replacement. 

 

A Practical Example: DXC’s CoreIgnite 

CoreIgnite is a high-performance orchestration and digital ledger platform designed to work alongside existing core systems (on prem or cloud based) and enables:  

  • Seamless integration with new payment services and fintech partners on their existing core systems 
  • Accelerated product launches and delivery of digital experiences on legacy cores. 
  • Monetisation of infrastructure through APIs and embedded finance opportunities. 
  • Modernisation of operations with phased migration and cloud-ready capabilities. 
  • By adopting platforms like CoreIgnite, Banks can unlock agility, innovation, and new revenue streams—ensuring they remain relevant and resilient in a fast-changing market.

Conclusion 

The future of payments for UK Banks lies in embracing orchestration and digital ledger platforms. These solutions act as payment hubs and simplify integration, offering a pragmatic path to modernisation. Banks that invest in flexible, scalable infrastructure will be best positioned to deliver the services their members expect while safeguarding agility and operational stability.
