Title: The Evolution of Banking: Embracing Banking as a Service (BaaS)

Introduction: The landscape of financial services is undergoing a transformative shift with the emergence and widespread adoption of "Banking as a Service" (BaaS). This essay explores the dynamics, motivations, and challenges surrounding the integration of banking functions into non-financial sectors.
Body:

1. Rise of BaaS: The concept of BaaS involves extracting core banking functions, such as "deposits," "loans," and "foreign exchange," and making them accessible to non-financial entities through APIs. This trend has gained momentum globally, with Japanese mega-banks like Mitsubishi UFJ Financial Group and Mizuho Financial Group signaling a commitment to bolster their BaaS initiatives in 2024.

2. Origins and Regulatory Shifts: The inception of BaaS in Japan can be traced back to the June 2018 amendments to the Banking Act, paving the way for legal recognition of electronic payment agents. Further, the June 2020 enactment of the Financial Services Act established new intermediaries, referred to as "Enablers," facilitating the integration of financial services into non-financial platforms.

3. APIs and Functionality: BaaS categorizes APIs into "reference APIs" for viewing account information and "update APIs" for actual account operations. This API-driven approach enables seamless interaction between financial institutions and external entities, promoting what is also known as embedded finance.

4. Diverse Applications of BaaS: BaaS extends beyond traditional banking services, finding applications in payment apps like PayPay and marketplace platforms like Mercari's "Merpay." These instances exemplify the versatility of BaaS, enabling functionalities ranging from asset management within payment apps to integrated payment features within e-commerce platforms.

5. Merits of BaaS: The advantages of BaaS lie in its ability to democratize access to financial services. By API-izing banking functions, non-financial companies can selectively incorporate essential features into their services, providing users with a seamless and integrated experience.

6. Diverse Approaches by Financial Institutions: Financial institutions, especially net banks, are intensifying their BaaS efforts. Examples include SBI New Bank Group's "BANKIT," GMO Aozora Net Bank's "BaaS by GMO Aozora," and Minna no Ginko's BaaS initiatives. Additionally, Rakuten Bank's partnership with JR East Japan to establish "JRE BANK" adds to the vibrancy of BaaS discussions.

7. Unique Strategy of SBI Net Bank: Notably, SBI Net Bank takes a distinctive approach with its NEOBANK, offering a full banking experience rather than providing individual APIs. This strategic move aims to ensure a consistent user experience across different companies while allowing each entity to add its unique features on top of the shared banking functionalities.

8. Regulatory Dynamics: The regulated nature of financial services, governed by licensing systems and held by license holders, distinguishes institutions like SBI Net Bank as both license holders and enablers. The essay underscores the importance of regulatory changes and legal frameworks in fostering the growth of BaaS.

Conclusion:
In conclusion, the evolution of BaaS represents a paradigm shift in the financial services industry, allowing for greater collaboration between financial and non-financial sectors. As we witness the continual expansion of BaaS initiatives globally, the landscape of banking is undergoing a profound transformation, ushering in a new era of financial accessibility and innovation.
