Open banking sounds like a contradiction in terms. How can banking – which relies on the most secure processes, safeguarding our most private and sensitive data from financial crime – possibly align with the idea of openness, sharing, and accessibility?
But as the number of digital banking users has grown – projected to reach 80 million in the US alone by 2028, up from 52 million in 2023 – so has the complexity of the financial services ecosystem. Accenture reports that 73% of people engage with multiple banks beyond their main bank, while 58% purchased a financial service or product from a new provider in the last 12 months.
Customers are hungrily taking advantage of the breadth of banking products and financial services that can help them manage their finances better and make their money work harder. And within the last decade, open banking has emerged as a way of greasing the wheels by offering consumers greater control of their financial data. Consumers can now choose to transfer that data between banks and financial services providers, reaping the rewards of more personalized banking products and consolidated views of their finances. Here’s how it works.
What is open banking?
As the name suggests, open banking is literally opening up the closed data that’s traditionally been held by and within each bank. Customers can consent to sharing select financial data, such as their transaction history, with third-party fintech providers via their bank’s APIs, typically with read-only permission.
Open banking regulation exists to address consumers’ data privacy concerns. Third-party providers must be authorized by a relevant regulatory body – a National Competent Authority, or NCA. But since open banking is a relatively new innovation, countries are at different levels of maturity when it comes to this regulatory infrastructure.
In the UK, for example, where banks’ participation in open banking was mandated in 2018, fintech companies can enrol on the Financial Conduct Authority’s Open Banking Directory. In the US, on the other hand, equivalent enforcement has only been proposed by the Consumer Financial Protection Bureau (CFPB) in 2023, meaning implementation of open banking APIs is voluntary and inconsistent.
