The impact of a higher leverage ratio on the South African economy

Abstract

We employ a micro-founded and stock-and-flow-consistent model to study the impact of a higher leverage ratio on the South African economy. The model provides a rich representation of institutional balance sheets. The relationship between bank capital, risk-taking behaviour, lending spreads, and economic activity is highlighted. The financial accelerator mechanism operates through the balance sheets of all economic institutions. The introduction of a higher leverage ratio is likely to generate negative economic impacts in the short run.
