Open API, open banking


Many banks are currently opening their core functions through application programming interfaces (APIs). This happens on the one hand as a consequence of new regulation regulations and on the other because they have realized that this opens up new business opportunities. The revised Payment Services Directive (PSD2), for example, obliges European banks to share their customer transaction and counterparties with third parties, including, for example, Fintechs, retailers, telecommunication providers, payment service providers and account aggregation services. But also where the PSD2 has no binding effect, as in the US, a large number of API projects deployed by banks demonstrates the current trend to open banking.


Many banks have come to the conclusion that opening towards new players is a perfect way to provide innovations without employing an army of developers. Banks are aware of the growing challenges of Fintechs and other market players, but they have also realized that working with them can be an opportunity to maintain their position in the new digital economy.
