Introduction

Open banking is quietly redefining what counts as creditworthiness for Nigerian small businesses. Instead of requiring physical assets as security, lenders can now assess a company's ability to repay based on the pattern and reliability of its cash inflows. This shift has the potential to unlock financing for millions of commercially active businesses that have long been excluded from the formal banking system due to strict collateral demands.

What Happened

In December 2025, the World Bank reported that barely one in twenty Nigerian MSMEs held bank credit, identifying collateral requirements, short loan terms, and expensive borrowing as primary barriers. For decades, the default lending question has been a standard that leaves many daily-trading businesses financially invisible despite active operations. Nigeria has taken steps to address this gap: the National Collateral Registry launched in 2016, and the Secured Transactions in Movable Assets Act of 2017 provided statutory backing for using inventory, receivables, and equipment as collateral. Open banking builds on this foundation by making a business's transaction history transferable, verifiable, and actionable in real time, replacing static document submissions with live, permissioned data flows from financial institutions.

Why This Matters

Traditional SME loan applications typically demand audited financial statements, tax returns, and physical assets, creating barriers for businesses operating informally or without fixed property. Open banking changes the process by enabling structured data access directly from banks through a standardized API, pulling account balances, transaction histories, and indebtedness records with proper consent. As FairMoney's managing director Henry Obiekea noted in early 2026, richer financial data allows lenders to differentiate risk levels rather than pricing all borrowers uniformly. A World Bank backed pilot with Access Bank and Sterling Bank found that cash-flow underwriting showed promise, and the institution's $500 million FINCLUDE programme, approved in December 2025, aims to onboard 250000 MSMEs into debt financing using an AI enabled digital appraisal platform. Beyond expanding access, the model also improves rejection quality lenders can spot instability, unusual cash movements, or patterns linked to non-performing loans, reducing bad debt while expanding opportunity for credit worthy firms that lack tangible assets.

Key Takeaways

  • Open banking shifts collateral from physical assets to verified cash-flow data, broadening the pool of borrowable businesses.
  • Nigeria's open banking framework, though still in transition after a delayed nationwide rollout, is designed to enable structured, real-time financial data sharing.
  • World Bank initiatives and bank-level pilots are already testing cash-flow underwriting, with early results suggesting faster, more inclusive credit decisions.
  • Consent frameworks require explicit, revocable permission, but the economic reality means opting out may mean losing access to financing entirely.
  • Success will be measured not just by API connectivity, but by whether previously uncreditworthy businesses gain access to appropriately priced capital and clear feedback when declined.

Conclusion

Open banking holds the potential to transform Nigeria's SME lending landscape by turning daily transaction data into legitimate collateral. However, the technology's impact depends on how banks and lenders choose to interpret that data whether it expands credit access or simply automates more precise exclusions. For business owners, understanding how their cash flow will be assessed becomes as important as the business itself. As the ecosystem matures, the real win will be credit worthy startups gaining affordable capital, portable financial histories, and meaningful feedback, even when turned down.
