In order to understand how the industry is responding to the opportunities of open banking, Ovum conducted a series of interviews with leading thinkers and market participants from across the value chain.


  • Where the industry has become particularly focused is APIs that go beyond basic regulatory requirements. It is here that banks see the opportunity not just to support the launch of a new wave products and services, but to generate revenue.
  • One of the biggest changes that open banking drives is the emergence of developers and TPPs as a new customer base. The usability, accessibility, and breadth of APIs and developer services will be a new competitive battleground.
  • Analysis of the registrations under PSD2 from the national competent authorities (NCAs) in Europe shows that, of the non-bank TPPs registered by the end of June as either an AISP, PISP, or both, 63% are UK-based.
