Open banking services

In Banking and capital markets

Open banking is a disruptive force in the financial services industry. It will change how consumers engage with their banks and financial services providers, introduce new channels and promote innovation and competition in financial products.

What EY can do for you

Maintaining a trusted open banking ecosystem requires a clear customer-centric business strategy, new business and operating models, rapid innovation cycles, flexible technology integration, enhanced security and an updated privacy and liability regime. We see open banking as a strategic opportunity for both new and established institutions – and also a strategic risk.

To address the regulatory changes and prepare for the new environment in Europe, banks are establishing transformation programs, with initial focus on meeting regulatory deadlines and delivering good customer outcomes. Banks should now be confident in complying, and put in place robust security measures, develop an understanding of liability and create compelling customer propositions.

In other countries, the regulatory imperative is less, however,  open banking continues to develop, driven by customer expectation and enabled by new technology.

Consumer uptake of open banking is expected to drive new competitive dynamics. Plus, financial services firms will also need to monitor these trends and review appropriateness and sustainability of ongoing business strategies. New data and payments capabilities, through open banking, have the potential to trigger industry-level digital transformation, unlocking innovation and driving competition.

How would the bank transform its operating model amidst a merger?

Successful Day-1 integration with best-in-class operating model design led to a holistic transformation.

One of India’s leading public sector banks merged with two other banks and the combined entity resulted in one of the country’s largest banking entities. It was the largest merger in the Indian banking industry at the time.

At the time of the merger, the bank’s primary objective was to achieve seamless Day-1 integration with minimal customer disruption and smooth structural, cultural, operational, and functional integration. The bank sought support to manage the scale and complexity of this integration. It also wanted to ensure that the combined entity realized all synergistic opportunities for future growth.

EY worked with the bank to deploy a destination operating model for providing a competitive advantage across the value chain. The new operating model set a foundation for scalable growth and higher efficiencies across sales, credit, collections, and internal operations.

EY led Day-1 integration and destination model roll-out to transform the bank

The transformation involved building an operating model with a revamped organizational structure, efficient operations and a culturally aligned workforce.

EY conducted a detailed diagnostic and comprehensive Day-1 readiness assessment across the business, support and control functions of the bank. The key focus areas were:

  • Harmonization of products, processes and policies
  • Ensuring minimal customer disruption
  • Enhancing geographical reach with an optimum product mix
  • Alignment and integration of unified digital platforms for customers

Subsequent to the successful Day-1 merger, EY created a destination operating model with an 18-month long transformation roadmap targeting:

  • A four-tiered credit operating model with specific focus on large corporates, mid and small corporates, micro, small and medium enterprises
  • A revamped organization structure to create specialized verticals including fintech and collections and recovery
  • A comprehensive assessment of potential cost and revenues synergy arising from the amalgamation and developing a 3-year roadmap for the bank for realizing the same
  • Seamless customer experience with inter-operability across branches and other digital and physical channels
