Description

Global Open Finance Expands Beyond Banking as Financial-Data Infrastructure Develops in 2026

Key Highlights

India's Account Aggregator ecosystem reached over 325 million cumulatively linked financial accounts and more than 530 million cumulative fulfilled consents by July 2026.
UK Open Banking APIs recorded over 99% successful-call rate and availability in July 2026.
New Zealand's regulated Open Banking data-sharing requests more than doubled from over 9 million in May to more than 19 million in July 2026.

Open Finance Extends Across Financial Products

Financial-data sharing is broadening beyond payment accounts to include areas such as credit, investments, insurance, pensions, and business finance, expanding the range of data and institutions involved in Open Finance.

Financial-Data Ecosystems Show Growing Activity

Increasing account connections, fulfilled consents, API usage, and repeated data access indicate expanding operational activity across Open Banking ecosystems, although adoption indicators differ considerably between markets.

Broader Connectivity Raises Infrastructure Requirements

As financial-data sharing extends across more products and participants, interoperability, data quality, permission management, accreditation, liability, and governance become increasingly important to effective implementation.
