Learning Objectives:

  • Define BaaS, platform banking, and embedded finance.

  • Explain how APIs enable these models.

  • Understand the ecosystem of BaaS providers.

4.1 Banking-as-a-Service (BaaS)

Banking-as-a-Service (BaaS) is a model where licensed banks offer non-banking companies access to their services, enabling them to embed financial products into their offerings [citation:1,4,9]. The University of West Georgia’s course is an “in-depth study on the Banking as a Service model where licensed banks offer non-banking companies access to their services. We will examine the relationships between the financial institutions, BaaS providers, and Fintechs” . GIFT IFI’s course also covers “BaaS Platforms and Ecosystem Enablers” as a core topic .

Key Components of BaaS:

  • Licensed Banks: Provide the banking license, regulatory compliance, and balance sheet.

  • BaaS Platforms: Technology providers that connect banks to FinTechs or non-financial companies via APIs.

  • FinTechs/Non-Financial Companies: Use BaaS to embed financial services (e.g., lending, deposits, cards) into their products.

Related Models: The University of Warsaw course also mentions “Fintech-as-a-Service and Payments-as-a-Service” . The GIFT IFI curriculum covers “BaaS Platforms and Ecosystem Enablers” and “Account Aggregators and Consent Architecture,” which are key elements of the BaaS ecosystem .

4.2 Platform Banking

Platform banking refers to a business model where financial institutions act as a platform, providing a marketplace for third-party products and services. The University of Warsaw course includes “platform economics” as a core topic . Platform banking creates an ecosystem where banks can offer a wider range of services to their customers without having to develop them in-house. This model leverages the power of network effects, where the value of the platform increases as more participants (both providers and users) join.

4.3 Embedded Finance

Embedded finance is the integration of financial services into non-financial platforms . The University of Warsaw course includes “embedded finance, Banking-as-a-Service, Fintech-as-a-Service, Payments-as-a-Service” as key topics . This allows non-financial companies (e.g., e-commerce platforms, ride-hailing apps) to offer services like payments, lending, or insurance seamlessly within their existing user experience. The University of Sussex course focuses on the wider ecosystem of embedded finance and platform banking .
