Key Indicators for Availability & Performance
- The regulatory requirements, as defined by EBA Guidelines 2.2, 2.3 and 2.4.
- For each requirement, OBIE guidelines to explain how these should be calculated by ASPSPs for the dedicated interface.
- For each requirement, an OBIE recommended benchmark for the dedicated interface.
- These benchmarks are based on feedback from the developer community for what a well performing API should support to enable PSU adoption and should be achievable by ASPSPs in most cases.
- Benchmark availability and AISP and PISP response times are based on the best performing endpoints of the CMA9 in the UK at the end of 20181 and factor in 1000 milliseconds (ms) per megabyte (MB) to cater for larger payloads.
- Benchmarks for CBPII response times are based upon international card schemes’ authorisation response times. It is noted that this benchmark would not apply to complex corporate models, but rather simple account models only.
- OBIE will review these benchmarks on a regular basis.
ASPSPs must, as per EBA/FCA requirements, ensure (at least) parity between the availability and performance of their best performing PSU interface and that of their dedicated interface.
Separately, to ensure an appropriate base level of availability and performance of the dedicated interface, ASPSPs should aim to adhere to the OBIE Recommended Benchmark, unless (in the unlikely event) that this would bring the dedicated interface below the availability and performance of the PSU interface.
