Over 135.0 million consumers worldwide use open banking services processing over $11.6 trillion in projected transaction value, with 85.0% of US consumers connecting bank accounts via APIs, the UK surpassing 11.0 million active users, and over 2,700 authorized third-party fintechs operating across Europe. Driven by regulatory shifts like CFPB Section 1033 in the United States and PSD2/PSD3 in the European Union, direct developer APIs are eliminating legacy screen scraping in favor of tokenized financial data access. The figures below come from empirical research published by Open Banking Limited (OBIE), Plaid, the Consumer Financial Protection Bureau (CFPB), the European Banking Authority (EBA), and Juniper Research.

1. Global Adoption: 135M Worldwide Users and $11.6T Transaction Scale
Open banking has expanded from a regional European compliance mandate into a global standard for consumer-permissioned financial interoperability. Juniper Research documents over 135.0 million global open banking users processing an estimated $11.6 trillion in cumulative transaction volume.
Over 80 jurisdictions worldwide have now implemented or drafted open banking regulations, accelerating the migration toward open finance across Latin America, Asia-Pacific, and North America.
