What is NextGenPSD2 and why does it matter for the digital euro?
NextGenPSD2 is the Berlin Group's open API specification for account access under PSD2. For the Digital Euro it provides a European-governed standard for how payment-service providers connect to the ECB's central-bank ledger, avoiding proprietary US-stack APIs.Source: event

Background

The Berlin Group is a pan-European payment-industry initiative focused on open-banking standards, best known for its NextGenPSD2 framework, which defines API specifications that allow third-party payment-service providers and fintechs to access bank accounts under the EU's revised Payment Services Directive (PSD2). Its membership covers European banks, payment processors and fintech associations working toward a common technical foundation for account-to-account payments, data access and Open Finance.

On 24 April 2026 the Berlin Group signed a technical standards agreement with the ECB alongside ECPC and nexo standards, contributing its open-banking API specifications as a reference framework for Digital Euro infrastructure. The Digital Euro involves not just card-payment terminals but also account-based access flows, where Open Finance standards defining how payment-service providers connect to a central-bank ledger entry point are directly relevant. The Berlin Group's NextGenPSD2 work covers precisely this layer.

The group's significance for Digital Euro sovereignty is at the account-access layer: if the ECB's Digital Euro distribution goes through licensed payment-service providers (the banks and fintechs that will distribute digital euros to end users), those providers need standardised API connections to the ECB ledger. Berlin Group specifications are the European-governed alternative to building those connections on proprietary US-tech-stack APIs. The April agreement formalises their role in that infrastructure.
