Executive Summary
Open Finance is far more than a technology trend; it is the next paradigm in the evolution of financial services. Moving beyond the limits of Open Banking, this model enables an ecosystem in which users’ financial data (banking, insurance, investments, pensions, and more) can be shared securely and with explicit consent via APIs. The result is unprecedented disruption that unlocks hyper-personalisation, new business models, and deeper financial inclusion. For business leaders and technology teams, understanding and adopting Open Finance is no longer optional — it is a strategic imperative to stay competitive. In this definitive guide, we explore its architecture, benefits, risks, the global regulatory landscape, and a practical roadmap to help you embed Open Finance at the core of your business.
The Paradigm Shift: Why Open Finance is the Strategic Conversation You Need to Lead
Over the past decade, digitalisation has reshaped entire industries. Now it is the financial system’s turn. If you think Open Finance is merely an extension of Open Banking — or a topic reserved for banks and fintechs — you are only seeing the tip of the iceberg.
Open Finance represents a fundamental shift in data ownership and portability. Control moves from institutions to the user, turning financial information into an asset the customer can “plug into” different platforms to receive greater value. For organisations, this creates a unique opportunity to stop selling isolated products and start delivering integrated solutions that solve real customer lifecycle problems.
As discussed in the episode “Is Open Finance a financial revolution or just hype?” (EP. 92 of the Digital Experience podcast), the key question is no longer whether Open Finance is “a revolution or just hype”, but how organisations can capitalise on this shift to avoid being left behind.
“Open Finance is not just a technological opportunity; it is a strategic decision about how we want to build trust with the end user. It is the bridge between fragmented data and an integrated, coherent, and contextualised experience”.
Christian Patiño, digital innovation expert.
This mindset shift is critical. Companies that continue to operate in silos, protecting “their” data, will watch more agile and open competitors build value ecosystems around customers — and capture their loyalty.
From Open Banking to Open Finance: The Evolution Towards a Connected Ecosystem
To understand the potential, it is essential to differentiate the two concepts. While related, their scope is dramatically different.
- Open Banking: Focuses primarily on banking data. In many jurisdictions it requires banks to open access — via secure APIs and always with customer consent — to current accounts, savings accounts, and credit cards. Its main objective was to increase competition in payments and account aggregation services.
- Open Finance: Extends this concept to a person’s or company’s entire financial universe. It includes data from mortgages, personal loans, insurance policies, investment funds, pension plans, and products from non-bank institutions. It goes further still by potentially integrating “adjacent finance” data such as from utilities (telcos, energy providers) or large retailers.
A simple analogy: Open Banking lets you see all your tools of a single type (e.g. all your hammers) in one toolbox. Open Finance lets you see all your tools of every type (hammers, saws, screwdrivers) — and then suggests what you can build with them.
| Feature | Open Banking | Open Finance |
| Data Scope | Bank accounts, cards. | The full financial spectrum: investments, insurance, credit, pensions. |
| Primary Objective | Increase competition in payments and account aggregation. | Create a 360° customer view to deliver hyper-personalised services. |
| Main Actors | Banks and payment providers (TPPs). | Banks, fintechs, insurtechs, asset managers, regulators, telcos, retailers. |
| Key Benefit | Unified account visibility. | Integrated customer experiences and new business models (BaaS, Embedded Finance). |
| Maturity Level | Regulated and established in several regions. | In regulation-and-growth phase, with leading implementations in the UK and Brazil. |
Strategic Benefits: The “Why” for Every Leader in the Organisation
The impact of Open Finance is not uniform; it resonates differently depending on the role. Below we break down the value for each decision-maker.
For C-levels and Founders: Redesigning the Business Model
- Creating New Revenue Streams: Open Finance powers business models such as Banking-as-a-Service (BaaS) — where any business can offer financial products without being a bank — and Embedded Finance, which integrates financial services (e.g. “buy now, pay later”, insurance at checkout) natively into the customer experience.
- Exponential Growth in Lifetime Value (LTV): With a 360° customer view, you can anticipate needs. A customer seeking a mortgage may also need home and life insurance. Open Finance enables you to offer the full solution at the right moment — increasing retention and LTV.
- Market Expansion and Risk Reduction: Access to alternative data (such as utility payments or non-banked income history) enables more accurate and inclusive credit scoring models. This opens previously underserved segments, expanding the addressable market sustainably.
- Sustainable Competitive Advantage: The edge no longer sits in the product, but in the ecosystem. Organisations that build open platforms and collaborate with other players create a network effect that siloed competitors struggle to replicate.
For Product and Technology Leaders: Building Next-Generation Experiences
- True Hyper-Personalisation: Forget basic segmentation. With Open Finance, you can build a “segment of one”. For example, a personal finance app can analyse spending, income, and investments to recommend a dynamic, automated savings plan that adapts in real time.
- Radical Friction Reduction (Onboarding and KYC): Processes like opening an account or applying for credit — which today can take days and require multiple documents — can be reduced to minutes. Identity and affordability can be verified via API in seconds, dramatically improving conversion rates.
- Faster Time-to-Market: API- and microservice-based architectures let you “plug in” new capabilities instead of building from scratch. Need a scoring engine? A payments gateway? An insurance product? Integrate a specialist partner and ship MVPs in weeks, not months.
- From Technical Debt to Strategic Agility: Open Finance drives modernisation of technology stacks. It forces organisations away from rigid monoliths towards flexible, modular, cloud-native models — an investment in future agility.
The Global Landscape: From Regulation to Practical Innovation
Open Finance is not theory — it is happening now. However, adoption varies significantly by region, creating a patchwork of regulatory and market approaches.
- United Kingdom (The Regulated Pioneer): The UK was the first to force adoption through the Open Banking Implementation Entity (OBIE). Today it remains the most mature market, with millions of consumers and businesses using services ranging from personal finance management (apps like Plum and Moneybox) to SME accounting optimisation. Its success set the foundations for the rest of the world.
- European Union (The Standardising Giant): Through the Payment Services Directive (PSD2), the EU created a legal framework for Open Banking. Implementation has been more fragmented than in the UK, but it has still driven innovation. The EU is now debating PSD3 and Financial Data Access (FiDA), which move directly towards a regulated Open Finance framework across the Union.
- Brazil (The Exponential Success Story): Led by the Central Bank, Brazil rolled out Open Finance in phased, mandatory, and ambitious waves. Combined with the enormous success of the instant payments system PIX, it has created a vibrant ecosystem. Nubank, Banco Inter, and other fintechs use these rails to deliver simplified onboarding, personalised credit, and seamless payment experiences to tens of millions of Brazilians.
Latin America (The Fast Followers):
- Mexico: The 2018 Fintech Law was regionally pioneering by anticipating standardised APIs. While implementation has been gradual, the ecosystem is maturing quickly with aggregators such as Belvo and Finerio Connect.
- Chile: Its recently approved Fintech Law establishes an Open Finance System with a clear governance model, set to accelerate innovation and competition over the coming years.
- Colombia: Colombia is advancing with a voluntary but standardised model led by the financial regulator, with strong market appetite for openness.
The Architecture of the Future: Technologies that Enable Open Finance
Implementing Open Finance requires a modern, secure, and scalable technology architecture. These are the core pillars:
- APIs (The Backbone): APIs are the channels through which data flows. In Open Finance, RESTful APIs are the standard. They are not just technical tools — they are products in their own right. They must be secure, well documented, reliable, and easy for third parties to consume.
- Microservices Architecture: Legacy monoliths are too rigid. Microservices break applications into smaller, independent services (e.g. one for KYC, another for scoring, another for payments). This enables teams to update, scale, or replace components without impacting the rest of the system — delivering unmatched agility.
- Cloud Infrastructure: The scale, resilience, and security Open Finance demands are most efficiently achieved in the cloud (AWS, Google Cloud, Azure). Cloud enables demand spikes, advanced security controls, and lower operating costs.
- Security and Consent Management (The Trust Layer): Security is not optional — it is the foundation of the model. This includes:
- Authentication and authorisation standards: Protocols such as OAuth 2.0 and OpenID Connect are essential to ensure only authorised parties access data.
- Data encryption: Both in transit (TLS 1.2+) and at rest (AES-256).
- Consent management platforms: Users must have granular, transparent control over what they share, with whom, and for how long. Consent must be easy to understand — and easy to revoke at any time.
The Real Challenges: Overcoming Barriers to Adoption
Despite its enormous potential, the road to Open Finance is not without obstacles. The winners will be those who anticipate them and manage them proactively.
- Regulatory fragmentation: There is no single global standard. Operating across jurisdictions means navigating a complex web of local laws, increasing compliance costs.
- Cybersecurity and fraud risk: Greater connectivity expands the attack surface. Protecting data against breaches and sophisticated fraud is an ongoing arms race, requiring continuous investment in technology and talent.
- User adoption and education gap: Many consumers still distrust sharing financial data or do not understand the benefits. Investment in financial education and outstanding UX design is essential — building trust through transparency and control.
- Monetisation and ROI: Who pays for the infrastructure? How are ecosystem revenues shared? Defining sustainable business models where all actors (banks, fintechs, users) capture value is key to long-term scale.
Roadmap: 5 Steps to Embed Open Finance into Your Strategy
Where should you start? Implementing Open Finance is not an IT project — it is a business transformation. Here is a strategic roadmap:
- Phase 1: Strategic and capability assessment.
- Ask yourself: Where are the biggest frictions in my customer journey that Open Finance could solve? What new products or services could we create?
- Audit your tech stack: Is our architecture modular enough to integrate external APIs? How much technical debt do we carry?
- Phase 2: Use case prioritisation.
- Do not try to do everything at once. Identify 1–2 high-impact, low-risk use cases to start. Examples: a fully digital onboarding flow, or an account aggregation tool for your customers.
- Define clear KPIs to measure success: reduced onboarding time, higher conversion, improved NPS, etc.
- Phase 3: Architecture design and partner selection.
- Define the technology blueprint: Do we build internally, or leverage a platform provider (data aggregator)?
- Identify strategic allies: Look for product, legal, and business partners that complement your capabilities (e.g. Soho.lat for digital product design and development).
- Phase 4: MVP build and governance.
- Build a first product version focused on the prioritised use case.
- In parallel, establish a robust data governance framework. Define data ownership, consent management, and compliance controls.
- Phase 5: Launch, iterate, and scale.
- Launch the MVP to a controlled user segment.
- Collect feedback continuously and iterate using agile methods.
- Once value is validated, plan expansion into additional use cases and markets.
The Future is Open: Open Data and the Synergy with AI
Open Finance is only the beginning. The next frontier is Open Data, where the same principles of portability and user consent will be applied to healthcare, government, telecommunications, and more. This will create a truly holistic view of the individual, enabling proactive and predictive services that currently sound like science fiction.
This data explosion will become fuel for Artificial Intelligence. AI algorithms will be able to analyse Open Finance data streams to:
- Detect fraud patterns in real time with unprecedented accuracy.
- Create truly personalised autonomous financial advisers.
- Automate insurance underwriting and complex risk evaluation processes.
Conclusion: Your Next Strategic Move
Open Finance has moved from promise to tangible reality — and it is redefining the rules of the game. For business and technology leaders, ignoring it means risking irrelevance.
The question is not whether you should adopt Open Finance, but how and how quickly. The transition requires strategic vision, investment in modern technology, and — above all — an uncompromising commitment to building trust through transparency and customer value.
Organisations that embrace openness, collaborate, and put the user at the centre of their data strategy will not only survive disruption — they will lead the next generation of digital financial services.
