How Development Finance Can Unlock Nigeria’s Growth | Prof. Joseph Nnanna

How can development banks expand access to credit without creating excessive risk? And what role can development finance play in tackling some of Nigeria’s biggest economic challenges?In this episode of Beating Sisyphus, we speak with Prof. Joseph Nnanna, Chief Economist at the Development Bank of Nigeria (DBN), about credit constraints, financial inclusion, MSME financing, inflation, and the broader challenge of economic development in Nigeria.Prof. Nnanna explains how information asymmetries, limited collateral, volatile cash flows, and high borrowing costs restrict access to finance for productive firms. We discuss how DBN uses wholesale lending, capacity building, and partial credit guarantees to address these market failures while managing default risk and moral hazard.The conversation then turns to Nigeria’s macroeconomy: why higher interest rates alone may not be enough to control inflation, the importance of fiscal and monetary policy coordination, and why diversification beyond oil remains critical to long-term growth.Finally, Prof. Nnanna shares concrete examples of how development finance can unlock productivity—from rural electrification to solving coordination failures between small businesses—and explains why he remains optimistic about Nigeria as an emerging market.CHAPTERS00:00 Introduction01:15 From the Private Sector to Development Economics04:54 Why Do Credit Constraints Matter?08:29 How the Development Bank of Nigeria Works13:43 Managing Credit Risk and Supporting Larger Firms17:23 Financial Inclusion and Underserved Businesses21:59 Credit Guarantees and the Moral Hazard Problem25:47 Why Economic Theory Can Behave Differently in Nigeria26:34 Inflation, Interest Rates, and Monetary Policy28:17 Why Fiscal and Monetary Policy Must Work Together33:03 How Development Finance Affects the Broader Economy33:42 Rural Electrification and Local Economic Development35:26 Solving Coordination Failures: The Tomato Example38:19 Why Nigeria Is an Emerging Market to Watch40:55 Closing ThoughtsBeating Sisyphus is a production of the Cañizares Center for Emerging Markets in collaboration with the Cornell Emerging Markets Institute Club (EMIC).#Nigeria #EmergingMarkets #DevelopmentFinance
