SWIFT creates financial sector API blueprint

Brussels, 16 October 2018

SWIFT has today published a blueprint for common API standards following collaboration with
European banking standards bodies, STET and Berlin Group NextGenPSD2 – who together represent
many of the region’s banks and payment service providers.

As pressure from regulators and customers shift banking towards more open access to financial
services, SWIFT is playing a lead role in unlocking the potential of API technology by providing the
neutral collaboration platform to develop the common data standards the industry needs.
SWIFT’s white paper, Towards a global platform for the Financial Services API economy, published
today, concludes that a successful transition to an API-based financial ecosystem is only possible if
financial standards bodies converge towards a shared business standardisation methodology.

Regulators around the world have identified the need for interoperability among financial institutions
as they move towards a more open banking model. SWIFT, STET and Berlin Group NextGenPSD2
are at the centre of efforts to avoid fragmentation, isolation, and the needless complexities that will
frustrate attempts to build the value-added services that customers want.

SWIFT is working to minimise inefficiencies caused by differing regulatory specifications that could
limit opportunities for common API frameworks across different regions and potentially require different
solutions for every market. The cooperative has lent its long-standing expertise in standards,
specifically ISO 20022 – the standard for electronic data interchange between financial institutions –
to work alongside STET and Berlin Group NextGenPSD2 in Europe to define the building blocks for
the new services that will spring from the new API economy.

Stephen Lindsay, Head of Standards at SWIFT, said: “APIs are at the core of SWIFT’s strategy and
a key part of how we deliver a faster, more transparent experience to our customers. Overall, the
financial services industry has been slow to adopt APIs, but it’s catching up fast. With the wealth of
experience we have working with standards at SWIFT, it is fitting that we’re at the forefront of API
standardisation and efforts to avoid fragmentation of approach as the industry embraces API
technology. In our role as neutral facilitator, we have made the most of our unique position to create
and maintain the standards necessary for processing financial transactions efficiently and securely.”

SWIFT, STET and Berlin Group NextGenPSD2 have concluded a first phase where a business model
for the PSD2 Account Information Services has been defined using common standards. This data
model will be the foundation for any API definitions and will enable interoperability among PSD2
participants. This work follows a successful collaboration on the creation of a common API framework
between SWIFT and Australia’s New Payments Platform (NPP).

Hervé Robache, PSD2 API Coordinator at STET, said: “STET has been involved with PSD2 API
topics since 2016. Our participation in different working groups at the European level has confirmed
our assumption that there is strong demand for common standards. Having the building blocks that
can accommodate all business needs and be reused by all API providers is critical to achieving this
goal, which is why the development of this ISO20022 model is such an important and exciting
development.”
 

Dr. Ortwin Scheja, Chief Editor at Berlin Group NextGenPSD2, said: “For Berlin Group
NextGenPSD2, alignment and convergence on PSD2 API standards has always been a crucial
objective which has consistently been communicated into the market since the start in 2016. The
alignment with SWIFT and STET on the PSD2 relevant data models is a perfect example of a core

component in the harmonisation that Berlin Group NextGenPSD2 advocates. We believe that open
and harmonised PSD2 API standards are the necessary building blocks of an interoperable market.”
