UK Open Banking API Performance 2021-2022

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

We studied the performance of 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 our patented APImetrics quality scoring system, CASC (Cloud API Service Consistency).
