Brussels, May 29, 2026: ETPPA Welcomes Bank for International Settlements (BIS) Project Aperta Report on Cross-Border Open Finance Interoperability

ETPPA is proud to have participated as an observer in the Bank for International Settlements (BIS) Project Aperta, an important initiative exploring how open finance ecosystems can interconnect across borders through trusted interoperability.

The report highlights the growing importance of cross-border interoperability as open finance frameworks continue to develop around the world. Project Aperta proposes a "network of networks" approach, enabling domestic open finance ecosystems to remain independent while facilitating trusted cross-border exchange of data and services through a neutral interoperability layer.

Importantly, the report highlights a key lesson from international experience that should resonate strongly in Europe's ongoing Financial Data Access (FIDA) discussions:

“International experience suggests regulation-led approaches with standardised APIs can support faster and more coordinated adoption.”

As policymakers consider the future of open finance in Europe, Project Aperta provides further evidence that clear rules, common standards and trusted frameworks are critical to unlocking innovation, competition and cross-border interoperability.

For ETPPA, the report reinforces the importance of a robust European open finance framework that enables trusted data sharing, promotes innovation and supports the development of interoperable digital financial services across the Single Market.

ETPPA encourages stakeholders following the FIDA negotiations to take note of the report's findings and looks forward to continuing to contribute to discussions on the future of open finance in Europe.
