Open Banking Expands Worldwide with Different Implementations: Here’s What’s Happening

Mercator has completed a worldwide review of countries embracing open banking. This review identifies the approach each country has taken to legislate open banking and also identifies the standards bodies that they rely on to implement the APIs that deliver access to data and payments. This knowledge is important for any supplier that intends to enter these markets. Mercator Advisory Group’s latest research report, Open Banking Goes Worldwide: U.S. Inroads are Keeping Pace with Global Efforts, evaluates the legislation and technology standards that are being promulgated in six countries including the U.S.

Our last report documented the stabilization of open banking within the EU and especially the U.K., but the success of open banking in the EU has expanded interest into other countries including Australia, Hong Kong, Japan, New Zealand, Singapore and the U.S.

“Combined with the 36 countries within the Single Euro Payments Area (SEPA), there are now a potential of 41 countries implementing open banking at some level,” comments Tim Sloane, Research Director at Mercator Advisory Group and the author of the report. “Understanding what services are being prioritized in which countries combined with a recognition of the standardized APIs being used in each country enables financial institutions and fintechs to better plan their cross-border and market-entry strategies.”

Those U.S financial institutions and fintechs building out an API portal strategy need to understand how each country intends to authenticate participants, secure the API infrastructure and establish standard APIs for a range of use cases.

This research report has 19 pages and 1 exhibit.
