The BaaS revolution – Disruption and opportunities in financial services

Summary

Open banking has moved well beyond regulatory compliance into a genuine growth engine for banks across Asia-Pacific, unlocking fee-based revenue streams that sit outside the traditional interest income model. As banks expose their data and infrastructure through APIs, a new layer of collaboration with fintechs, marketplaces, and non-banking businesses is reshaping how financial products reach customers, through embedded finance, super-apps, buy-now-pay-later, and Banking-as-a-Service.

Australia, India, Singapore, Thailand, and Malaysia lead the region's open banking push, each shaped by different regulatory frameworks, from Australia's Consumer Data Right to India's Account Aggregator system built on the back of UPI. Banking-as-a-Service extends this further, letting banks and fintechs offer their core infrastructure to non-financial businesses so retailers, platforms, and marketplaces can embed payments, lending, and other financial products directly into their own customer journeys.

The BaaS ecosystem breaks down into three distinct roles: providers, the licensed banks and financial institutions exposing their infrastructure; enablers, typically fintechs that build specialized solutions on top of that infrastructure; and distributors, the non-banking businesses with large customer bases that embed financial products into their platforms. Each role carries its own path to monetization, from white-labeled customer journeys to marketplace access and specialized vertical solutions.

• Buy-now-pay-later, super-apps, and data monetization as adjacent open banking opportunities
• Six-step implementation roadmap covering compliance, API design, and partner onboarding
• Case examples from leading Asia-Pacific banks building developer-focused API stacks

For bank executives and fintech strategists, understanding where their organization fits, provider, enabler, or distributor, is the starting point for building a durable Banking-as-a-Service strategy as fee income growth increasingly depends on it.
