This paper examines the determinants of net interest margins in four regional blocks in Sub-Saharan Africa and one comparator block in the Eastern Caribbean. Using bank-level data, we find that countries with a high level of operating costs, a high ratio of equity to total assets and high treasury bill interest rates have higher net interest margins. Moreover, high operating costs are associated with low measures of institutional quality and a small size of bank operations. We find support for the view that market structure is also partly responsible for high net interest margins in Sub-Saharan Africa. If interpreted causally, high operating costs and a high ratio of equity to total assets and, indirectly, institutional factors such as the rule of law, are the most important factors in accounting for high interest margins in the East African Community, relative to other regions.

This study assesses the determinants of banking system efficiency in sub-Saharan Africa (SSA) and asks what, besides the degree of efficiency, explains the low level of financial development in the region. It uses stochastic frontier analysis to measure efficiency and a generalized method of moments system to explain financial development. SSA banks are found to be generally cost-efficient, but nonperforming loans undermine efficiency, which suggests that improvement in the regulatory and credit environments should improve efficiency. The political and the economic environment have held back financial development in SSA.

Financial sectors in low-income sub-Saharan Africa (SSA) are among the world's least developed. In fact, assets in most low-income African countries are smaller than those held by a single medium-sized bank in an industrial country. The absence of deep, efficient financial markets seriously challenges policy making, hinders poverty alleviation, and constrains growth. This book argues that building efficient and sound financial sectors in SSA countries will improve Africa's economic prospects. Based on a review of the key features of financial systems, it discusses the main obstacles and challenges that financial structures pose for SSA economies and recommends steps that could address major shortcomings in implementing the reform agenda.

In its fourth edition, this report focuses on recent developments in Africa's banking sectors and the policy options for all stakeholders. The study of banking sectors across all African sub-regions includes the results of the EIB survey of banking groups operating in Africa. Three thematic chapters address challenges and opportunities for financing investment in Africa: Crowding out of private sector lending by public debt issuance The state of bank recovery and resolution laws in Africa Policy options on how to finance infrastructure development. The report finds that in many African banking markets, the last two years saw a pause in financial deepening. However, a rising share of banking groups report improving market conditions and plan a structural expansion of their operations in Africa and a continued push for new technologies.

Economic growth in sub-Saharan Africa this year is set to drop to its lowest level in more than 20 years, reflecting the adverse external environment, and a lackluster policy response in many countries. However, the aggregate picture is one of multispeed growth: while most of non-resource-intensive countries—half of the countries in the region—continue to perform well, as they benefit from lower oil prices, an improved business environment, and continued strong infrastructure investment, most commodity exporters are under severe economic strains. This is particularly the case for oil exporters whose near-term prospects have worsened significantly in recent months. Sub-Saharan Africa remains a region of immense economic potential, but policy adjustment in the hardest-hit countries needs to be enacted promptly to allow for a growth rebound.

The sharp decline in oil and other commodity prices have adversely impacted sub-Saharan Africa. Nevertheless, the region is projected to register another year of solid economic performance. In South Africa, however, growth is expected to remain lackluster, while in Guinea, Liberia, and Sierra Leone the Ebola outbreak continues to exact a heavy economic and social toll. This report also considers how sub-Saharan Africa can harness the demographic dividend from an unprecedented increase in the working age population, as well as the strength of the region's integration into global value chains.

Growth momentum in sub-Saharan Africa remains fragile, marking a break from the rapid expansion witnessed since the turn of the millennium. 2016 was a difficult year for many countries, with regional growth dipping to 1.4 percent—the lowest level of growth in more than two decades. Most oil exporters were in recession, and conditions in other resource-intensive countries remained difficult. Other nonresource-intensive countries however, continued to grow robustly. A modest recovery in growth of about 2.6 percent is expected in 2017, but this falls short of past trends and is too low to put sub-Saharan Africa back on a path of rising living standards. While sub-Saharan Africa remains a region with tremendous growth potential, the deterioration in the overall outlook partly reflects insufficient policy adjustment. In that context, and to reap this potential, strong and sound domestic policy measures are needed to restart the growth engine.
