Commercialising Open Banking: A Practical Guide
Around 60 jurisdictions have now mandated or regulated open banking. The infrastructure is being built. The standards are maturing. But most banks are still treating it as a compliance cost, not a commercial asset.
That’s the gap this guide addresses.
Banks bear real ongoing costs to deliver open banking: building and maintaining standards-compliant APIs, security certifications (ISO 27001, SOC 2 Type 2, FAPI), 24/7 third-party support, fraud prevention, and continuous updates as standards evolve. Without a clear path to revenue or strategic value, investment stays minimal and the potential stays unrealised. The third parties connecting to those APIs, meanwhile, often expect everything for free.
It doesn’t have to work that way.
The guide walks through three distinct approaches to building commercial models around open banking APIs, each with practical implementation steps.
Foundational APIs are your market presence play. Basic account information APIs, mandated by regulation in most markets, deliver real strategic value even at low or no direct cost: higher customer retention, credit decisioning advantages, and your entry point into open finance ecosystems. There’s also a clear commercial path: usage tiers, rate limiting, and support packages that sit on top of the regulatory baseline without conflicting with it.
Premium APIs generate direct revenue. Payment initiation, identity and income verification, Confirmation of Payee (CoP) and Verification of Payee (VOP): these APIs have clear costs and clear value, making them natural candidates for commercial pricing. The guide covers what to charge, how to structure terms, and the specific technical and liability requirements for each.
Distribution channel APIs are where open banking becomes a genuine growth channel. Instead of customers coming to your branch or website, your products appear wherever financial needs arise: an accounting platform surfaces your SME credit line when a client’s cash flow tightens, a savings product appears in a fintech app when a user shows intent to save. Brazil is already running this model at scale (2.3 billion successful API communications a week). The UK, EU, UAE, and Saudi Arabia are all moving in the same direction.
Beyond the three models, the guide addresses:
This isn’t theory. It’s built on what we’ve learned helping banks, central banks, and regulators across six continents implement open banking infrastructure, starting with the UK open banking standard, which our founding team helped design.

The UAE built a fully operational national Open Finance API Hub in 12 months. The UK took nearly five years. Brazil took almost three. This guide examines the six building blocks, coalition model, and realistic delivery timeline that made that speed possible, and what regulators and central banks need to get right to do the same.
At FDX Global Summit 2026, one theme dominated: banks are already moving on digital assets, but open finance doesn't support them yet. Ozone API's Co-Founder and CEO Chris Michael shares what it will take to close that gap, from solvable technical challenges to the case for global standards over market-by-market patchwork.
