Open Finance builds on open banking by using APIs to securely share financial data—not just from banks, but also from pensions, investments, mortgages, insurance, and more. It’s empowering a unified, real-time, and personalized financial experience across platforms and providers.
1. What Is Open Finance?
Open Finance extends traditional open banking APIs—transaction and balance sharing—to a broader financial ecosystem. It encompasses pensions, mortgages, investments, insurance, and beyond. APIs are enabling consumers and businesses to securely share, access, and monetize financial data—unlocking deeper personalization and new services
-
Booming investment: The global open banking API market is projected to grow from $30 billion in 2025 to over $300 billion by 2035 (26% CAGR).
-
Embedded finance surge: By 2025, embedded finance spans >$7 trillion globally, with real-time API-driven payments exceeding $500 billion annually.
-
BaaS expanding fast: Banking-as-a-Service allows non-bank companies to offer financial services via APIs—forecasted to reach $70 billion by 2030.
2. Global Regulatory Push & Frameworks
-
United States
The CFPB finalized open banking rules under Section 1033 of Dodd-Frank, phasing out screen scraping and mandating secure, standardized data access—boosting competition and consumer control.
-
Europe
PSD3 (Payment Services Directive 3) will strengthen Strong Customer Authentication (SCA), enforce tighter API standards, and support innovative real-time/account payments (e.g. VRP).
-
Asia-Pacific & LATAM
Canada, Mexico, Brazil, Australia, Vietnam, and Singapore are rolling out open finance frameworks—some permissive, some regulatory—with API directories, data access rules, and consumer protection mechanisms under way.
