UK Open Banking API Performance 2022-2023

UK Open Banking API Performance 2022-2023

The UK continues to be at the forefront of the global Open Banking revolution thanks to the proactive attitude of regulators. 

These regulators helped create an Open Banking ecosystem that encourages and facilitates smaller banks and new entries, including fintechs and neobanks, to participate in the Open Banking market alongside the largest banks.

As the most advanced Open Banking market in the world, the UK provides an example of best practices in the implementation of API-based Open Banking that other jurisdictions can use as a model.

In this follow-up to our 2020-21 and 2021-22 reports, we studied the performance of the Open Banking APIs exposed by the large CMA9 UK banks, traditional High Street banks, credit card providers and building societies, and new entrant banks (neobanks).

The endpoints were provided by the banks and measured using the APImetrics active API monitoring service, including our patented quality scoring system, CASC (Cloud API Service Consistency).

The data in this report, produced by APImetrics, has been generated from real API calls made using the FAPI-compliant consent process with the support of their third-party provider (TPP) partner tomato pay. All calls were made between July 1, 2022 and June 30, 2023.
