How banking-as-a-service (BaaS) works and industry outlook

Across industries, digital transformation is democratizing data to enable greater transparency. New technologies are opening up legacy systems to emerging startups and third parties and, in some cases, putting data directly in the hands of consumers.

In financial services, Banking-as-a-Service (BaaS) platforms have surfaced as a key component of open banking , in which banks provide more financial transparency options for account holders by opening their application programming interfaces (APIs) for third parties to develop new services.

Fintechs have been encroaching on incumbent institutions in the banking game but by moving into the BaaS space, tech-savvy legacy banks can turn this looming threat into an opportunity.

What is banking-as-a-service?

BaaS is an end-to-end process that allows fintechs and other third parties to connect with banks' systems directly via APIs so they can build banking offerings on top of the providers' regulated infrastructure, as well as unlock the open banking opportunity reshaping the global financial services landscape.

Techy-savvy legacy banks can fend off the encroaching threat of fintechs by moving into the BaaS space to share their data and infrastructure. In a matter of years, access to this level of information will become table stakes for digitally native customers so banks that begin now will be ahead of the curve, and likely rewarded with high demand.

How BaaS Works Business Insider Intelligence

In addition to getting ahead in open banking, legacy institutions that launch their own BaaS platforms are also opening up new revenue streams. The two main monetization strategies for BaaS include charging clients a monthly fee for access to the BaaS platform or charging a la carte for each service used.

Tech-savvy legacy banks that create their own BaaS platforms now will not only get ahead of the open banking opportunity before their competitors, but also unlock a new stream of revenue by monetizing their platforms.

In the UK, the new revenue potential generated through open banking-enabled small- and medium-sized business and retail customer propositions was 500 million ($700 million) in 2018, per PwC and Business Insider Intelligence expects that to grow at a 25% compound annual growth rate to reach 1.9 billion ($2 billion) by 2024.

Beyond adding a new revenue stream, developing a BaaS solution also allows legacy banks to establish relationships and forge partnerships with emerging fintechs thereby keeping themselves ahead of the trends that will inevitably follow once BaaS and open banking become mainstream.
