Open banking continues to spread worldwide and is heading for the United States, in what some have been calling its “smartphone moment.” The infrastructure is falling into place to support open banking, and the Consumer Financial Protection Bureau has begun safeguarding the consumer protections necessary for this to happen.

In a recent PaymentsJournal podcast, Amit Shastri, Senior Director of Product Management at Worldpay from FIS, and James Wester, Co-Head of Payments at Javelin Strategy & Research, discussed the various payment rails that will facilitate open banking and what the benefits could be for banks, merchants, and consumers.

The Taxonomy of Open Banking

It’s important to understand the terminologies used in open banking, a new topic for many people. There are key differences between account-to-account (A2A) payments and open banking. A2A payments rely on legacy banking systems and often involve manual user steps, resulting in a suboptimal user experience. Open banking is not limited to the bank’s technology but can be seamlessly integrated into other apps with a stronger focus on conversion rates and experiences. A2A payments tend to lack interoperability across regions, whereas open-banking payments have the potential to be integrated into cross-border payments. In short: Although all open-banking payments are A2A payments, the reverse is not true.

In the United States, open banking is centered on the API-based connectivity that enables the sharing of bank account and balance information. U.S. consumers have become familiar with linking their bank accounts as part of the checkout process, then leveraging that connection to make payments again and again.

The term “real-time payments,” or RTP, refers to the underlying infrastructure that enables instant or near-instant transfer of payments between two parties. RTP operates 24 hours a day, weekends, and bank holidays. Open banking is effectively the overlay of services on these RTP rails, and it has the potential to revolutionize payments for consumers, retailers, small businesses, corporations, and governments. 

Where Open Banking Stands

According to Shastri, open banking accounted for nearly $525 billion of e-commerce transaction value in 2022 and is expected to see a 13% compound annual growth rate through 2026. Some of the key successes of open banking around the world are seen in Brazil, which has a payment scheme driven by the Central Bank of Brazil, and in India with UPI,
