CREDIT RISK AND BANK COMPETITION IN SUB-SAHARAN AFRICA

Alphonse Noah, Luc Jacolin and Michael Brei

No 2018-27, EconomiX Working Papers from University of Paris Nanterre, EconomiX

Abstract: This paper investigates the impact of bank competition in Sub-Saharan Africa on bank non-performing loans, a measure of credit risk. Using bank-level data for a sample of 221 banks from 33 countries over the period 2000-15, we find a non-linear or U-shaped relationship between bank competition and credit risk. In other words, increased bank competition has the potential to lower credit risk via efficiency gains (lower credit cost, operational gains). However, the positive effects may be outweighed by adverse effects of excessive competition (lower profit margins, increased risk incentives). We also find that credit risk in Sub-Saharan Africa is not only related to macroeconomic determinants, such as growth, public debt, economic concentration, financial deepening and inclusion, but also to the business and regulatory environment. These results may provide useful insights on how to design and adapt prudential and regulatory frameworks to the specific needs in developing countries.
