Case Study: UK Largest Bank achieves Open Banking Compliance with Wipro

A CMA9 bank achieves Open Banking Compliance within stipulated timelines

UK Largest Bank, part of the UK’s nine largest banks, needed to achieve Open Banking / PSD2 compliance within strict regulatory timelines for Open Banking Release 4 across AISP, PISP, and Commercial services. The challenge was made harder because the regulator’s R4 specification was not yet finalized, and the bank wanted Wipro to deliver on an outcome-based model with shared risk.

Wipro responded by rapidly scaling an onshore engineering team, transferring knowledge from earlier releases, and using Agile sprints to deliver compliant Open Banking APIs. Wipro also built a utility to simulate user journeys and automate testing, enabling 100% test automation and effective mocks. As a result, the bank achieved Open Banking compliance on time, avoided potential non-compliance penalties, and delivered integration testing in less than a week, with Wipro taking 100% fee at risk.
