SIX Launches b.Link – the Central Platform for the Standardized Sharing of Data Between Financial Institutions and Third-party Providers
With the b.Link platform, SIX is creating the basis for innovative partnerships between financial institutions and third-party providers. In a first step, providers of accounting solutions in Switzerland can connect to financial institutions under controlled conditions via the standardized b.Link interfaces. Corporate customers can thereby process account information and payment orders directly in their accounting software. SIX operates b.Link as an open platform and will continuously increase the number of participating financial institutions, third-party providers and applications.
Blog of Prof. Dr. Andreas Dietrich
“Open Banking will, in the medium to long term, gain in relevance also in Switzerland. With the appropriate technical interfaces (API, SOA) and/or regulatory requirements, private and corporate clients will be able to make their personal financial data accessible to other banks, financial service providers or FinTechs via open interfaces. Various initiatives are currently underway in Switzerland to create the possibility of open banking."
In his current blog, Andreas Dietrich presents the b.Link concept of SIX.
Voice of FinTech
The first podcast in the "Financial Markets" series, which is the result of the cooperation between SIX and "Voice of FinTech", is about Open Banking.
Therein, Sven Siat, Head Connectivity SIX, explains the differences between PSD2-driven open banking in the EU and the SIX open banking solution for the Swiss financial centre. It is important to him that cooperation between banks and third-party providers such as FinTechs must always work in both directions, not only when exchanging data but also when ensuring sufficient security in handling sensitive financial data.
