Open Banking and API Usage Statistics and Facts (2026)

Introduction

Open Banking and API Usage Statistics: Data has become the main driving force of the world, and open banking is one of the signs of this change. It has not only been a fintech trend but a foundation of the modern financial systems. What was initially a regulation-oriented initiative intended to create an environment of transparency and competition has now become a global economic power, literally changing the way individuals and businesses handle money.

APIs (Application Programming Interfaces) are the technology that enables this change, and they are the invisible yet powerful tools that allow banks to share data securely and let third parties develop new services without having to build entire systems from scratch.

This paper will give you a wide and rich picture of the 2025 landscape based on Open Banking and API Usage statistics, research insights, and the generation of financial impact. All the information will be collected from the most current research and industry sources.
