Banking Market Structure and Macroeconomic Stability: Are Low-Income Countries Special?

This paper explores the channels through which the structure of banking markets affects macroeconomic volatility

Abstract

The structure of banking markets in low income countries differs from developed market economies. Banking systems in lower income countries are typically smaller and less open than those in developed countries. Differences in market concentration are less stark. In this paper, we explore the channels through which the structure of banking markets affects macroeconomic volatility. We focus on granular effects: if the degree of market concentration in the banking sector is sufficiently high, idiosyncratic shocks affecting large banks can impact aggregate volatility. We find some weak evidence for granular effects in banking. However, our results suggest that a high share of domestic credit to GDP has a stronger effect on volatility in low income countries. The effects of de facto financial integration are stronger in these countries as well.
