Open Banking and Beyond: Monetizing APIs and Creating New Revenue Streams

As financial institutions undergo rapid digital transformation, Open Banking is emerging as more than a regulatory requirement—it’s a strategic opportunity to unlock innovation and generate new revenue streams. By exposing core banking functionalities via Application Programming Interfaces (APIs), banks and national switches are evolving into platforms that enable collaboration, foster financial inclusion, and monetize data-driven services.

This shift marks a new era: APIs are no longer just technical tools—they are products.

🔓 The Promise of Open Banking

Traditionally, banks held a closed architecture, controlling all customer interactions and data within proprietary systems. Open Banking changes this model by requiring (or encouraging) financial institutions to securely share data with third-party providers (TPPs), including fintechs, wallets, insurers, and merchants—with customer consent.

At the center of this model lies the Open API, which unlocks:

  • Real-time access to customer accounts

  • Seamless third-party app integrations

  • Custom product offerings based on behavioral insights

💡 From Compliance to Commercial Opportunity

Most institutions start Open Banking initiatives for compliance (e.g., PSD2 in Europe). However, forward-thinking players move beyond compliance to turn APIs into monetizable assets. Here’s how:

1. API-as-a-Product (APIaaP)

Offer APIs as subscription services or usage-based models to fintechs, merchants, or even other banks. Think:

  • Account verification API

  • Credit scoring API

  • KYC onboarding API

  • Payments initiation API

  • Lending-as-a-Service

2. Partner Ecosystem Monetization

Allow TPPs to build services on your platform. Generate value from:

  • Revenue sharing

  • Co-branded services

  • White-labeled solutions

3. Data-as-a-Service (DaaS)

With consent, anonymized and enriched financial data can be offered for:

  • Market insights

  • Credit profiling

  • Customer segmentation

🧠 What it Takes: Strategic Considerations

Monetizing APIs isn’t just about publishing endpoints. It requires:

  • Robust Developer Portals: With sandbox environments, clear documentation, and analytics.

  • Security & Compliance: OAuth 2.0, consent management, data minimization, and continuous risk monitoring.

  • Governance Models: To control access, pricing, SLAs, and dispute handling.

  • Cultural Shift: APIs are not side projects—they’re core business drivers. This requires cross-functional alignment.

🌍 National Switches: Catalysts for API Monetization

In countries like Ethiopia, where national switches play a central role, open APIs can:

  • Facilitate real-time P2P, merchant payments, and bulk disbursements

  • Bridge banks, wallets, and fintechs

  • Promote interoperability while reducing direct bilateral integrations

A centralized API gateway by a national switch ensures governance, scalability, and trust—key ingredients for monetization.

🚧 Challenges to Monetization

  • Market Dominance: Large platforms may resist standard integration if they already dominate.

  • Fragmentation: Without a central API standard, the ecosystem becomes siloed.

  • Skill Gaps: Building secure, scalable, and productized APIs requires specialized teams.

  • Incentives Misalignment: Smaller institutions may hesitate without clear ROI.

🚀 Looking Ahead: The API Economy for Finance

Banks and switches must reimagine themselves as platforms, not just service providers. Open APIs are at the heart of this transformation. By embracing the API economy, financial players can:

  • Accelerate financial inclusion

  • Launch embedded finance products

  • Improve CX through personalization

  • Generate non-interest revenue

✅ Call to Action

For financial institutions and national switches looking to lead:

  1. Define your API monetization strategy—compliance-only or commercial?

  2. Invest in secure and scalable API infrastructure

  3. Engage fintechs and developers—your future revenue may come from their innovation.

  4. Promote a centralized, standardized API framework, especially in national-level switch environments.

Understanding the Evolution: AI, ML, Deep Learning, and Gen AI

In the ever-evolving landscape of artificial intelligence (AI) and machine learning (ML), one of the most intriguing advancements is the emergence of General AI (Gen AI). To grasp its significance, it's essential to first distinguish between these interconnected but distinct technologies. AI, ML, and Deep Learning: The Building Blocks Artificial Intelligence refers to the simulation of human intelligence in machines that are programmed to think like humans and mimic their actions. Machine Learning, a subset of AI, empowers machines to learn from data and improve over time without explicit programming. Deep Learning, a specialized subset of ML, involves neural networks with many layers (hence "deep"), capable of learning intricate patterns from vast amounts of data. Enter General AI (Gen AI): Unraveling the Next Frontier Unlike traditional AI systems that excel in specific tasks (narrow AI), General AI aims to replicate human cognitive abilities across various domains.

Normalization of Database

Database Normalisation is a technique of organizing the data in the database. Normalization is a systematic approach of decomposing tables to eliminate data redundancy and undesirable characteristics like Insertion, Update and Deletion Anamolies. It is a multi-step process that puts data into tabular form by removing duplicated data from the relation tables. Normalization is used for mainly two purpose, Eliminating reduntant(useless) data. Ensuring data dependencies make sense i.e data is logically stored. Problem Without Normalization Without Normalization, it becomes difficult to handle and update the database, without facing data loss. Insertion, Updation and Deletion Anamolies are very frequent if Database is not Normalized. To understand these anomalies let us take an example of  Student  table.
