White paper
5 Lessons Learned From 3 Years of Open Banking
Hard-won lessons from three years of monitoring Open Banking APIs at scale.
Three years of continuous Open Banking API monitoring has produced a body of evidence about the patterns, problems, and progress of regulated API implementation across UK financial institutions.
This white paper synthesises that experience into five durable lessons — observations about where Open Banking succeeds and fails, the quality patterns that recur across institutions, and what the data says about the future of regulated API programmes.
Use it as a practical reference for teams building, managing, or governing Open Banking infrastructure.
