Bank Efficiency, Ownership, And Market Structure : Why Are Interest Spreads So High In Uganda ?

Abstract

Using a unique bank-level dataset on the Ugandan banking system over the period 1999 to 2005, we explore the factors behind consistently high interest rate spreads and margins. While foreign banks charge lower interest rate spreads, we do not find a robust and economically significant relationship between privatization, foreign bank entry, market structure and banking efficiency. Similarly, macroeconomic variables can explain little of the over-time variation in bank spreads. Bank-level characteristics, on the other hand, such as bank size, operating costs, and composition of loan portfolio, explain a large proportion of cross-bank, cross-time variation in spreads and margins. However, time-invariant bank-level fixed effects explain the largest part of bankvariation in spreads and margins. Further, we find tentative evidence that banks targeting the low-end of the market incur higher costs and therefore higher margins. JEL Classifications: G21, G30, O16

Essential Information Sharing Thresholds for Reducing Market Power in Financial Access: A Study of the African Banking Industry

“…More contemporary literature suggests that compared to big banks, smaller banks are linked to lower margins of interest (see Beck & Hesse, 2006;Ahokpossi, 2013) 2 . This is a paradox because, banks with greater market power are expected to be associated with lower interest margins because of the economies of scale they enjoy (internal and external advantages).…”

Information asymmetry and market power in the African banking industry

“…This study builds on this literature by investigating the relationship between information sharing offices and market power in African countries. We do so by analysing 162 banks from 42 African countries over the period of 2001-2011. Prior literature indicates that smaller banks are characterised with lower interest margins (see Beck & Hesse, 2006;Ahokpossi, 2013) 1 . In essence, relative to small banks, financial institutions with high market power are supposed to reduce their interest margins because of internal and external economies of scale.…”

Analisis Pengaruh Efisiensi dan Kecukupan Modal terhadap Kinerja Keuangan pada Bank Pembangunan Daerah di Indonesia

“…Hal ini karena bank besar memiliki portfolio yang lebih diversifikasi dibandingkan dengan bank kecil. Pengaruh positif GDP terhadap kinerja perbankan juga ditemukan oleh beberapa peneliti lain diantaranya Iannotta et al (2006); Beck dan Hesse (2006); Bonin et al (2003). Apabila dilihat dari ukuran BPD di Indonesia dikaitkan dengan bank yang ada di Amerika, maka BPD di Indonesia masuk dalam skala bank kecil.…”
