In the context of open banking, established banks need to transition from sole owners of financial data to partners in a distributed network of services, competing with fintech startups for consumer attention. To achieve this, they must balance data protection with data sharing, complying with evolving global privacy laws and granting consumers explicit consent before sharing their sensitive financial data. Banks are overcoming these limitations by remodeling their approach to data and building a data mesh using a modern developer data platform, which enables decentralization of data sharing and governance, and self-service consumption of that data. This decentralized approach encourages departments within the bank to adopt a "product-like" mentality toward the data within their domain, ensuring it is maintained and made available like any other service or product they deliver. By facilitating responsible, efficient data sharing across their financial institution, banks can open new doors for better customer outcomes and improved bottom lines.
