Case Study

Open Finance Brasil

Since its inception in 2019, Open Finance Brasil has become a global benchmark for secure data sharing and financial innovation. This case study explores how Raidiam's technology and expertise has supported Banco Central do Brasil's Open Finance initiative, overcoming key challenges to drive its success.

The Challenge

Building a Trusted, Scalable Open Finance Ecosystem in Brazil

When Brazil's central bank, Banco Central do Brasil (BCB), launched Open Finance Brasil, it set out to revolutionise the country's financial landscape. By giving consumers full control over their financial data, the initiative aimed to foster greater competition, enhance financial inclusion, and unlock more personalised products and services.

However, delivering a nationwide Open Finance ecosystem at scale came with several complex challenges:

  • Security & ScalabilityA robust infrastructure was needed to facilitate seamless, real-time data sharing across institutions.
  • InteroperabilityWith hundreds of banks, fintechs, and financial service providers participating, a consistent and standardised approach to API success was essential.
  • Regulatory ComplianceMeeting strict technical and security requirements to ensure that all participants adhered to central bank regulations.
  • Trust & AdoptionSuccess depended on widespread adoption from financial institutions and trust from consumers in the system's security and benefits.

Without a solid technological foundation, the ecosystem risked fragmentation, inefficiencies, and limited adoption. This is where Raidiam stepped in.
