Introduction to Core Banking Systems

Core banking systems are centralized platforms that handle essential banking operations—transaction processing, account management, ledgers, payments, and risk controls. In Nigeria, upgrading legacy systems is vital to meet rising customer expectations, fintech competition, and regulatory compliance. With the CBN emphasizing digital infrastructure expansion and financial inclusion, selecting the right platform is critical for banks of all sizes.

What Is a Core Banking Platform?

A core banking platform is a centralized architecture that simplifies key banking activities:

• Core functionalities: Account handling, real-time payments, general ledger and ledger reconciliation, and compliance
• Key characteristics: It must be scalable, secure, API-first, low-latency, and adaptable.
• Deployment methods: Leading platforms today are cloud-native, offering modularity, composability, and flexible cloud vs. on-premise deployments

Criteria for Evaluating Platforms

When choosing a core banking platform in Nigeria, consider:

• Regulatory compliance: Must align with CBN rules and Payments System Vision 2025 .
  
• Integration & Open Banking: Facilitate FinTech, USSD, CBDC interoperability via APIs.
  
• User experience: Secure multi-channel (mobile, USSD, web) frontends.
  
• Cost efficiency: Analyze TCO—license, migration, maintenance, updates.
