What is Banking-as-a-Service (BaaS)?

Banking-as-a-Service (BaaS) is an advanced business model in which financial institutions make their banking services available to third parties via APIs (application programming interfaces). These third parties can be other institutions or non-banks that want to expand their product range to include financial services.

By using APIs, external development teams and companies can access established banking services and integrate them into their own applications to create innovative financial products or improve their processes.

Forms of Banking-as-a-Service

  • Banking-as-a-Service takes various forms, including Software-as-a-Service (SaaS), which is the provision of banking software via the Internet.
  • Business-Process-as-a-Service (BPaaS) is a way to outsource specific business processes in banking.
  • Infrastructure-as-a-Service (IaaS), on the other hand, denotes the provision of basic banking infrastructures such as servers and computing power via the Internet.

Why is BaaS relevant in banking?

BaaS in banking accelerates the development of innovative financial products. Outsourcing institutions can offer more powerful systems and processes and thus generate additional revenue. At the same time, sourcing companies can react more flexibly and quickly to new market conditions. Studies show that this can reduce operating costs by up to 30%.

Benefits of Banking-as-a-Service

  • Agility and innovation: BaaS enables banks to make their services more agile and develop innovative products to market in a shorter period of time.
  • Cost efficiency: By using external services, banks can reduce costs as they do not have to manage all processes internally.
  • Access to technologies: Financial institutions can access the latest technologies without having to set up extensive IT infrastructure themselves.

Limitations of Banking-as-a-Service

The use of BaaS comes with challenges, including data protection and security concerns. The feeding of bank data into third-party systems requires robust security measures.

Moreover, financial institutions must ensure that their BaaS implementation complies with regulatory requirements – in particular the material outsourcing requirements pursuant to MaRisk AT 9 – and data protection guidelines.

BaaS: supplementary custom development

The integration of custom development can contribute to overcoming the limitations of BaaS. By developing customized applications, financial institutions can meet their own specific requirements while benefiting from the advantages of BaaS.

This combination allows for more flexible and bespoke solutions while ensuring regulatory compliance. The synergy between BaaS and custom development paves the way for a transformation of the German financial landscape.

Which banks and institutions may benefit from BaaS?

A combination of BaaS and custom development is a solid basis for developers to build upon. APIs allow them to create bespoke solutions tailored to specific customer needs. According to a report by Gartner, 90% of new corporate applications could be API-based by 2025. This shows the great potential of BaaS integration and custom development.

In particular smaller banks and up-and-coming fintech start-ups can benefit from BaaS by gaining access to established banking services. Larger institutions can use BaaS as a means of diversifying their service portfolio and intensifying their digitalization strategies.

It is expected that 70% of banks worldwide will integrate BaaS into their business models by the end of 2024 in order to strengthen their competitive position.
