Open Banking in Singapore

Singapore exemplifies a hybrid approach to open banking and open finance, combining regulatory guidance with market-driven innovation and public digital infrastructure. The Monetary Authority of Singapore (MAS) has fostered API adoption through its API Playbook, Financial Industry API Register, and the groundbreaking SGFinDex platform.

MAS's approach began with the Finance-as-a-Service (FaaS) API Playbook in 2016, which provided guidelines and recommended standards for financial institutions to develop and publish APIs. Rather than mandating participation, MAS encouraged adoption through industry engagement and the establishment of the API Exchange (APIX), a cross-border platform for financial institutions and fintechs to discover and test APIs.

The most significant development was the launch of SGFinDex (Singapore Financial Data Exchange) in 2020. SGFinDex is a public digital infrastructure, developed jointly by MAS and the Smart Nation and Digital Government Group, that enables individuals to retrieve their financial information from across government agencies and financial institutions through a single consent mechanism. It uses Singapore's National Digital Identity (Singpass) for authentication.

SGFinDex currently covers data from major banks (DBS, OCBC, UOB, Standard Chartered, HSBC, Citibank, and Maybank), the Central Provident Fund (CPF), the Housing Development Board (HDB), and the Inland Revenue Authority. Users can view consolidated information about their bank accounts, credit cards, loans, investments, insurance policies, pension contributions, and housing data in participating financial planning applications.

Singapore's approach is notable for its integration of government data alongside financial institution data, creating a holistic view of an individual's financial position. The government-backed nature of SGFinDex, combined with Singpass identity verification, has helped build consumer trust. MAS continues to explore expansion into real-time data sharing, more financial products, and cross-border data portability within ASEAN.
