Question to the HM Treasury:

To ask the Chancellor of the Exchequer, what key performance indicators his Department uses to assess the performance of Open Banking; and what recent assessment he has made of the performance of Open Banking.

The independent Open Banking Implementation Entity (OBIE) is responsible for assessing the performance of Open Banking, and HM Treasury’s view is informed by their assessment.

The OBIE’s latest published assessment of Open Banking performance, made in March 2019, shows that in that month the average availability of Open Banking APIs was 97%, the average response time was 798 milliseconds, and that 38.2 million successful API calls had been made, representing over 97% of the total number of calls made to APIs.
